Ultrastructural and molecular characterization of diversity among small araphid diatoms all lacking rimoportulae. I. Five new genera,eight new species

Pennate diatoms are important contributors to primary production in freshwater and marine habitats. But the extent of their diversity, ecology, and evolution is still largely unknown. This is particularly evident among the clades of pennate diatoms without raphe slits, whose diversity is likely underestimated due to their small size and features that can be difficult to discern under light microscopy. In this study, we described five new araphid genera with eight new species based on morphological observations (light and electron microscopy) and molecular data (nuclear‐encoded small subunit ribosomal RNA and chloroplast‐encoded rbcL and psbC): Serratifera varisterna, Hendeyella rhombica, H. dimeregrammopsis, H. lineata, Psammotaenia lanceolata, Castoridens striata, C. hyalina, and Cratericulifera shandongensis. We also transferred Dimeregramma dubium to Hendeyella dubia. Phylogenetic analysis of the molecular data revealed that all the newly established taxa fell into a monophyletic group, with Fragilariforma virescens located at the base. The group was composed by two subclades: one comprising Castoridens, Cratericulifera, and Plagiostriata, and the larger including also the rest of the new genera plus some of the smallest known diatoms, such as Nanofrustulum, Opephora, Pseudostaurosira, Staurosirella, and Staurosira with a high level of support. This study enhances the general knowledge on the phylogeny and biodiversity of a group of small araphid diatoms that have been generally poorly described both by electron microscopy and DNA sequence data.     

Molecular phylogeny of the diatom genera Amphora and Halamphora (Bacillariophyta) with a focus on morphological and ecological evolution

The taxonomic history of the diatom genus Amphora is one of a broad early morphological concept resulting in the inclusion of a diversity of taxa, followed by an extended period of revision and refinement. The introduction of molecular systematics has increased the pace of revision and has largely resolved the relationships between the major lineages, indicating homoplasy in the evolution of amphoroid symmetry. Within the two largest monophyletic lineages, the genus Halamphora and the now taxonomically refined genus Amphora, the intrageneric morphological and ecological relationships have yet to be explored within a phylogenetic framework. Critical among this is whether the range of morphological features exhibited within these diverse genera are reflective of evolutionary groupings or, as with many previously studied amphoroid features, are nonhomologous when examined phylogenetically. Presented here is a four‐marker molecular phylogeny that includes 31 taxa from the genus Amphora and 77 taxa from the genus Halamphora collected from fresh, brackish, and salt waters from coastal and inland habitats of the United States and Japan. These phylogenies illustrate complex patterns in the evolution of frustule morphology and ecology within the genera and the implications of this on the taxonomy, classification, and organization of the genera are discussed.     

Phylogeny of Gracilariaceae (Rhodophyta): evidence from plastid and mitochondrial nucleotide sequences

Gracilariaceae are mostly pantropical red algae and include ~230 species in seven genera. Infrafamilial classification of the group has long been based on reproductive characters, but previous phylogenies have shown that traditionally circumscribed groups are not monophyletic. We performed phylogenetic analyses using two plastid (universal plastid amplicon and rbcL) and one mitochondrial (cox1) loci from a greatly expanded number of taxa to better assess generic relationships and understand patterns of character distributions. Our analyses produce the most well‐supported phylogeny of the family to date, and indicate that key characteristics of spermatangia and cystocarp type do not delineate genera as commonly suggested. Our results further indicate that Hydropuntia is not monophyletic. Given their morphological overlap with closely related members of Gracilaria, we propose that Hydropuntia be synonymized with the former. Our results additionally expand the known ranges of several Gracilariaceae species to include Brazil. Lastly, we demonstrate that the recently described Gracilaria yoneshigueana should be synonymized as G. domingensis based on morphological and molecular characters. These results demonstrate the utility of DNA barcoding for understanding poorly known and fragmentary materials of cryptic red algae.     

Using a multigene phylogenetic analysis to assess generic delineation and character evolution in Verrucariaceae (Verrucariales, Ascomycota)

Verrucariaceae are a family of mostly crustose lichenized ascomycetes colonizing various habitats ranging from marine and fresh water to arid environments. Phylogenetic relationships among members of the Verrucariaceae are mostly unknown and the current morphology-based classification has never been confronted to molecular data. A multilocus phylogeny (nuLSU, nuSSU and RPB1) was reconstructed for 83 taxa representing all main genera of this family to provide a molecular phylogenetic framework necessary to assess the current morphology-based classification. Four main well-supported monophyletic groups were recovered, one of which contains seven robust monophyletic subgroups. Most genera, as traditionally delimited, were not monophyletic. A few taxonomic changes are proposed here to reconcile the morphology-based classification with the molecular phylogeny (Endocarpon diffractellum comb. nov., Heteroplacidium fusculum comb. nov., and Bagliettoa marmorea comb. nov.). Ancestral state reconstructions show that the most recent common ancestor of the Verrucariaceae was most likely crustose with a weakly differentiated upper cortex, simple ascospores, and hymenium free of algae. As shown in this study, the use of symplesiomorphic traits to define Verrucaria, the largest and type genus for the Verrucariaceae, as well as the non monophyly of the genera Polyblastia, Staurothele and Thelidium, explain most of the discrepancies between the current classification based on morphological similarity and a classification using monophyly as a grouping criterion.     

When molecules and morphology concur: the ‘Gondwanan’ midges (Diptera: Chironomidae)

A phylogeny of the Chironomidae subfamily Podonominae, significant in the history of phylogenetic biogeography, is estimated from an analysis of four genes. Fragments of two ribosomal genes (18S and 28S), one nuclear protein‐coding gene (CAD), and one mitochondrial protein‐coding gene (COI) were sequenced from specimens representing 13 of 15 genera, and analysed using mixed model Bayesian and maximum likelihood inference methods. Podonominae is monophyletic and sister to Tanypodinae – the shared development of the larval ligula is synapomorphic and diagnostic. Tribe Podonomini is monophyletic with the inclusion of Trichotanypus; tribe Boreochlini is a grade. Monophyly is confirmed for the genera Podonomus Philippi, Podonomopsis Brundin, Podochlus Brundin, Archaeochlus Brundin and Austrochlus Cranston, Edward & Cook: Parochlus Enderlein becomes monophyletic through the inclusion of Zelandochlus Brundin ( n.syn. ) with its type species, P. latipalpis (Brundin) n.comb. The ‘mandibulate’Archaeochlus plus Austrochlus is monophyletic with nonmandibulate Afrochlus weakly supported as a member of, or sister to, the African Archaeochlus. Subtending this group is Lasiodiamesa, although it associates in some analyses with the sister group Tanypodinae. Generic relationships coincide with those proposed based on morphology, particularly as understood via all life history stages of some problematic (autapomorphic, adult‐based) taxa. Divergence time analysis (beast ) allows inference of Mesozoic diversification of higher taxa in Podonominae, of appropriate timing for fragmentation of Gondwana, post‐African divergence, to have caused vicariance. Shallower nodes (within genera) imply both younger vicariance involving Antarctica and some recent dispersal, including southern to northern hemisphere movement in the New World. New Zealand taxa test controversial biogeographical relationships and show proximity to southern South America without direct Australian sister taxon pairs: dating implies persistence of midges through the ‘Oligocene’ bottleneck.     

Phylogeny of Chaetonotidae and other Paucitubulatina (Gastrotricha: Chaetonotida) and the colonization of aquatic ecosystems

Kånneby, T., Todaro, M. A., Jondelius, U. (2012). Phylogeny of Chaetonotidae and other Paucitubulatina (Gastrotricha: Chaetonotida) and the colonization of aquatic ecosystems. —Zoologica Scripta, 42, 88–105. Chaetonotidae is the largest family within Gastrotricha with almost 400 nominal species represented in both freshwater and marine habitats. The group is probably non‐monophyletic and suffers from a troubled taxonomy. Current classification is to a great extent based on shape and distribution of cuticular structures, characters that are highly variable. We present the most densely sampled molecular study so far where 17 of the 31 genera belonging to Chaetonotida are represented. Bayesian and maximum likelihood approaches based on 18S rDNA, 28S rDNA and COI mtDNA are used to reconstruct relationships within Chaetonotidae. The use of cuticular structures for supra‐specific classification within the group is evaluated and the question of dispersal between marine and freshwater habitats is addressed. Moreover, the subgeneric classification of Chaetonotus is tested in a phylogenetic context. Our results show high support for a clade containing Dasydytidae nested within Chaetonotidae. Within this clade, only three genera are monophyletic following current classification. Genera containing both marine and freshwater species never form monophyletic clades and group with other species according to habitat. Marine members of Aspidiophorus appear to be the sister group of all other Chaetonotidae and Dasydytidae, indicating a marine origin of the clade. Halichaetonotus and marine Heterolepidoderma form a monophyletic group in a sister group relationship to freshwater species, pointing towards a secondary invasion of marine environments of these taxa. Our study highlights the problems of current classification based on cuticular structures, characters that show homoplasy for deeper relationships.     

Molecular systematics of gerbils and deomyines (Rodentia: Gerbillinae,Deomyinae) and a test of desert adaptation in the tympanic bulla

Recent molecular studies in gerbils found multiple instances of discordance between molecular and morphological phylogenies. In this study, we analyse the largest molecular data set to date of gerbils and their sister group the deomyines to estimate their phylogenetic relationships. Maximum‐likelihood and Bayesian analyses were largely concordant, and both generally had high levels of node support. For gerbils, the results were generally concordant with previous molecular phylogenies based on allozymes, chromosomes, DNA/DNA hybridization and DNA sequences, and discordant with morphological phylogenies. None of the traditional gerbil tribes and subtribes were monophyletic. In addition, paraphyly was found in the genera Gerbillus, Gerbilliscus and Meriones as well as in five subgenera within Dipodillus, Gerbillurus and Meriones. Short branches separating taxa in small clusters within Dipodillus and Meriones suggest synonymy. Within deomyines, all genera and subgenera were monophyletic; however, two species groups within Acomys appear to contain synonymous taxa. We also find support for the discordance between molecular and morphological phylogenies in gerbils being partly due to convergent adaptations to arid environments, primarily in the suite of traits associated with inflation of the tympanic bullae. Relative bullar size does appear to be a desert adaptation and is correlated with aridity independent of phylogeny. Further, it varies more strongly along bioclimatic clines than between binary habitat classifications (desert versus mesic).     

Phylogeny and taxonomy of the Prenolepis genus‐group of ants (Hymenoptera: Formicidae)

Abstract. We investigated the phylogeny and taxonomy of the Prenolepis genus‐group, a clade of ants we define within the subfamily Formicinae comprising the genera Euprenolepis, Nylanderia, gen. rev. , Paraparatrechina, gen. rev. & stat. nov. , Paratrechina, Prenolepis and Pseudolasius. We inferred a phylogeny of the Prenolepis genus‐group using DNA sequence data from five genes (CAD, EF1αF1, EF1αF2, wingless and COI) sampled from 50 taxa. Based on the results of this phylogeny the taxonomy of the Prenolepis genus‐group was re‐examined. Paratrechina (broad sense) species segregated into three distinct, robust clades. Paratrechina longicornis represents a distinct lineage, a result consistent with morphological evidence; because this is the type species for the genus, Paratrechina is redefined as a monotypic genus. Two formerly synonymized subgenera, Nylanderia and Paraparatrechina, are raised to generic status in order to provide names for the other two clades. The majority of taxa formerly placed in Paratrechina, 133 species and subspecies, are transferred to Nylanderia, and 28 species and subspecies are transferred to Paraparatrechina. In addition, two species are transferred from Pseudolasius to Paraparatrechina and one species of Pseudolasius is transferred to Nylanderia. A morphological diagnosis for the worker caste of all six genera is provided, with a discussion of the morphological characters used to define each genus. Two genera, Prenolepis and Pseudolasius, were not recovered as monophyletic by the molecular data, and the implications of this result are discussed. A worker‐based key to the genera of the Prenolepis genus‐group is provided.     

Molecular phylogenetics of Erebidae (Lepidoptera,Noctuoidea)

As a step towards understanding the higher‐level phylogeny and evolutionary affinities of quadrifid noctuoid moths, we have undertaken the first large‐scale molecular phylogenetic analysis of the moth family Erebidae, including almost all subfamilies, as well as most tribes and subtribes. DNA sequence data for one mitochondrial gene (COI) and seven nuclear genes (EF‐1α, wingless, RpS5, IDH, MDH, GAPDH and CAD) were analysed for a total of 237 taxa, principally type genera of higher taxa. Data matrices (6407 bp in total) were analysed by parsimony with equal weighting and model‐based evolutionary methods (maximum likelihood), which revealed a well‐resolved skeleton phylogenetic hypothesis with 18 major lineages, which we treat here as subfamilies of Erebidae. We thus present a new phylogeny for Erebidae consisting of 18 moderate to strongly supported subfamilies: Scoliopteryginae, Rivulinae, Anobinae, Hypeninae, Lymantriinae, Pangraptinae, Herminiinae, Aganainae, Arctiinae, Calpinae, Hypocalinae, Eulepidotinae, Toxocampinae, Tinoliinae, Scolecocampinae, Hypenodinae, Boletobiinae and Erebinae. Where possible, each monophyletic lineage is diagnosed by autapomorphic morphological character states, and within each subfamily, monophyletic tribes and subtribes can be circumscribed, most of which can also be diagnosed by morphological apomorphies. All additional taxa sampled fell within one of the four previously recognized quadrifid families (mostly into Erebidae), which are now found to include two unusual monobasic taxa from New Guinea: Cocytiinae (now in Erebidae: Erebinae) and Eucocytiinae (now in Noctuidae: Pantheinae).     

Molecular phylogeny of grapsoid crabs (Decapoda, Brachyura) and allies based on two mitochondrial genes and a proposal for refraining from current superfamily classification

Grapsoid and ocypodoid crabs receive a lot of attention in the literature due to their predominance and important role as primary and secondary consumers in intertidal as well as supratidal marine habitats. They are especially species‐rich in the tropics, where they have been found to repeatedly invade terrestrial and freshwater habitats. However, the systematics of the crabs belonging to these two superfamilies is still not settled, despite recent steps clarifying phylogenetic relationships and introducing new taxa. In this study, a molecular phylogeny of grapsoid crabs primarily based on East African representatives is constructed based on DNA sequences of the mitochondrial small and large ribosomal subunits (12S and 16S rRNA), thus complementing previous molecular taxonomic studies that had been carried out with the American and East Asian fauna. In addition, selected representatives of all ocypodoid families and subfamilies were included. The monophyly of Grapsidae, Ocypodidae (sensu stuctu), Sesarmidae and Varunidae is well confirmed, if the genera Cyclograpsus, Helice are considered Varunidae and Euchirograpsus a Plagusiidae, as previously suggested. The monophyly of the family Gecarcinidae cannot be supported with our data. The family Plagusiidae in its present composition is polyphyletic. Special attention was given to the large family Sesarmidae, which has many endemic genera in the Indo‐West Pacific. According to this study, two of the most speciose genera, Chiromantes and Parasesarma, are not monophyletic and need to be redefined. On the higher taxonomic level, it becomes evident that both superfamilies, Grapsoidea and Ocypodoidea, are not monophyletic in their current composition, as exemplified by a proposed sister group relationship of Varunidae and Macrophthalmidae. These results confirm those from previous molecular studies and we therefore propose to refrain from the traditional use of the Grapsoidea and Ocypodoidea as monophyletic superfamilies and treat the constituent families separately.     

A checklist of algal species found in the East Siberian Sea in May 1987

Summary A checklist of microalgae found in sea-ice in the East Siberian Sea in May 1987 has been compiled. A total of 122 taxa have been identified, consisting of 101 taxa in 18 genera of pennate diatoms, 14 taxa in 8 genera of centric diatoms, 4 taxa in 3 genera of dinoflagellates (including Ebria sp.), and 2 taxa in 1 genus of chrysophytes (silicoflagellates); choanoflagellates (Craspedomonadales) were found in one sample.     

A Molecular Phylogenetic Investigation of Bakuella,Anteholosticha, and Caudiholosticha (Protista,Ciliophora, Hypotrichia) Based on Three‐Gene Sequences

Traditionally classifications of the Urostyloida have been mainly based on morphology and morphogenesis. Recent molecular phylogenetic analyses have been largely based on single‐gene data for a limited number of taxa. Consequently, incongruence has arisen between the morphological/morphogenetic and the molecular data. In this study, the three phylogenetic markers (SSU rDNA, ITS1‐5.8S‐ITS2 region, and LSU‐rDNA) of three urostyloid genera represented by four species (Bakuella granulifera, Anteholosticha monilata, Caudiholosticha sylvatica, and C. tetracirra) were sequenced to investigate their phylogeny. The results show that: (1) all three genera should be regarded as the members of the order Urostyloida within the subclass Hypotrichia, as indicated by morphological characters; (2) phylogenetic analyses and sequence similarities both indicate that neither Anteholosticha nor Caudiholosticha are monophyletic and the systematic assignment of both genera awaits further evaluation; and (3) Bakuella has a closer relationship with Urostyla than with bakuellids (e.g. Apobakuella and Metaurostylopsis), suggesting Bakuella may belong to the family Urostylidae rather than the family Bakuellidae.     

Interspecific plastidial recombination in the diatom genus Pseudo‐nitzschia

Plastids are usually uni‐parentally inherited and genetic recombination between these organelles is seldom observed. The genus Pseudo‐nitzschia, a globally relevant marine diatom, features bi‐parental plastid inheritance in the course of sexual reproduction. This observation inspired the recombination detection we pursued in this paper over a ~1,400‐nucleotide‐long region of the plastidial rbcL, a marker used in both molecular taxonomy and phylogenetic studies in diatoms. Among all the rbcL‐sequences available in web‐databases for Pseudo‐nitzschia, 42 haplotypes were identified and grouped in five clusters by Bayesian phylogeny. Signs of hybridization were evident in four of five clusters, at both intra‐ and interspecific levels, suggesting that, in diatoms, (i) plastidial recombination is not absent and (ii) hybridization can play a role in speciation of Pseudo‐nitzschia spp.     

Phylogeny of Mesoamerican freshwater mussels and a revised tribe‐level classification of the Ambleminae

Evolutionary and ecological hypotheses of the freshwater mussel subfamily Ambleminae are intensely geographically biased—a consequence of the complete exclusion of Mesoamerican taxa in phylogenetic reconstructions of the clade. We set out to integrate a portion of the Mesoamerican freshwater mussel assemblage into existing hypotheses of amblemine classification and evolution by generating a molecular phylogeny that includes four previously unsampled Mesoamerican genera and nine species endemic to that region. Given the traditionally hypothesized affinity to Nearctic mussels and the understanding that classification should reflect common ancestry, we predicted that (a) Mesoamerican genera would be recovered as members of the recognized tribes of the Ambleminae, and (b) genera would be supported as monophyletic. The mutilocus phylogeny (COI + 28S + 16S) reported herein does not fully support either of those hypotheses. Neither Cyrtonaias nor Psorula were supported as monophyletic and we predict several other Mesoamerica genera are also non‐monophyletic. The reconstructed phylogeny recovered four independent lineages of Mesoamerican freshwater mussels and these clades are distributed across the phylogeny of the Ambleminae, including the tribe Quadrulini (Megalonaias), Lampsilini (two lineages: Cyrtonaias explicata/Sphenonaias microdon, and Pachynaias), and a previously unrecognized, exclusively Mesoamerican and Rio Grande clade consisting of the genera Psoronaias, Psorula and Popenaias. The latter clade possesses several morphological characteristics that distinguish it from its sister taxon, tribe Lampsilini, and we recognize this newly identified Mesoamerican clade as a fifth tribe of the Ambleminae attributable to the Popenaiadini Heard & Guckert, 1970. This revised classification more completely recognizes the suprageneric diversity of the Ambleminae.     

Evolution of blindness in scolopendromorph centipedes (Chilopoda: Scolopendromorpha): insight from an expanded sampling of molecular data

Relative to its diversity (34 genera, 700 species), Scolopendromorpha has been undersampled in molecular phylogenetic analyses compared with the other chilopod orders. Previous analyses based on morphology have not resolved several key controversies in systematics and evolutionary morphology unambiguously. Here we apply new molecular and morphological data to scolopendromorph phylogenetics, with a focus on the evolution of blindness. The taxonomic sample includes 19 genera, many lacking previous molecular data, and diverse, cosmopolitan genera of Scolopendridae are sampled by multiple species. Phylogenetic analysis with Direct Optimization used 94 morphological characters and ca. 4.5 kb of sequence data from two nuclear (18S and 28S rRNA) and two mitochondrial (16S rRNA and COI) loci. A single most‐parsimonious cladogram selected after sensitivity analyses resolves Scolopendromorpha as monophyletic, and divides it into a blind clade of three families (Plutoniumidae, Cryptopidae, Scolopocryptopidae) and its ocellate sister group, Scolopendridae. Some species‐rich, cosmopolitan genera (Cormocephalus, Otostigmus, Scolopendra) in Scolopendridae are non‐monophyletic, and in several instances (e.g. New and Old World Scolopendra) relationships are more congruent with geographical distributions than with traditional classifications. The tribe Asanadini is particularly subject to parameter‐sensitivity, nesting in the combined analysis within Scolopendrini but as sister to all other Scolopendrinae for molecular data alone. The total‐evidence tree unambiguously optimizes trunk segmentation: a 23‐segmented trunk has a single origin in the blind clade. © The Willi Hennig Society 2011.     

Basal ischnoceran louse phylogeny (Phthiraptera: Ischnocera: Goniodidae and Heptapsogasteridae)

A phylogenetic analysis of generic relationships for avian chewing lice of families Goniodidae and Heptapsogasteridae (Phthiraptera: Ischnocera) is presented. These lice, hosted by galliform, columbiform and tinamiform birds are reputedly basal in the phylogeny of Ischnocera. A cladistic analysis of sixty‐two adult morphological characters from thirty‐one taxa revealed thirty equally parsimonious cladograms. The phylogeny is well resolved within Heptap‐sogasteridae and supports the monophyly of subfamily Strongylocotinae (sensu Eichler 1963 ). Resolution within Goniodidae is lower but suggests that the genera hosted by Columbiformes are largely monophyletic. Mapping host taxonomy on to the phylogeny of the lice reveals a consistent pattern which is largely congruent down to the rank of host family, although at lower taxonomic levels the association appears to be more complex. The inclusion of more louse taxa may help considerably to unravel the coevolutionary history of both the hosts and their parasites.     

Historical biogeography and diversification within the Neotropical parrot genus Pionopsitta (Aves: Psittacidae)

Aim We investigate spatial and temporal patterns of diversification within the Neotropical avifauna using the phylogenetic history of parrots traditionally belonging to the genus Pionopsitta Bonaparte 1854. This genus has long been of interest for those studying Neotropical biogeography and diversity, as it encompasses species that occur in most Neotropical forest areas of endemism. Location The Neotropical lowland forests in South and Central America. Methods Phylogenetic relationships were investigated for all species of the genus Pionopsitta and five other short‐tailed parrot genera using complete sequences of the mitochondrial genes cyt b and ND2 as well as 26 plumage characters. The resulting phylogeny was used to test the monophyly of the genus, investigate species limits, and as a framework for reconstructing their historical biogeography and patterns of diversification. Results We found that the genus Pionopsitta, as previously defined, is not monophyletic and thus the Chocó, Central American and Amazonian species will now have to be placed in the genus Gypopsitta. The molecular and morphological phylogenies are largely congruent, but disagree on the position of one of the Amazon basin taxa. Using molecular sequence data, we estimate that species within Gypopsitta diversified between 8.7 and 0.6 Ma, with the main divergences occurring between 3.3 and 6.4 Ma. These temporal results are compared to other taxa showing similar vicariance patterns. Main conclusions The results suggest that diversification in Gypopsitta was influenced mainly by geotectonic events, marine transgressions and river dynamics, whereas Quaternary glacial cycles of forest change seem to have played a minor role in the origination of the currently recognized species.     

Molecular phylogeny of the mega‐diverse rove beetle tribe Staphylinini (Insecta,Coleoptera, Staphylinidae)

Chatzimanolis, S., Cohen, I. M., Schomann, A. & Solodovnikov, A. (2010). Molecular phylogeny of the mega‐diverse rove beetle tribe Staphylinini (Insecta, Coleoptera, Staphylinidae). —Zoologica Scripta, 39, 436–449. Phylogeny of the rove beetle tribe Staphylinini is explored by parsimony and Bayesian analyses of sequences of four genes (COI, wingless, Topoisomerase I, and 28S) for 43 ingroup (various genera of Staphylinini) and eight outgroup (two genera of Paederinae, six genera of other tribes of Staphylininae) taxa. Analyses were conducted for each gene independently and for the concatenated data set. Results of the most robust combined analyses were compared with the morphology‐based phylogenies of Staphylinini (‘test phylogeny’), and with the conventional classification of this tribe. Molecular results were congruent with the ‘test phylogeny’ in the following: ancestors of Staphylinini were ‘Quediina‐like’ lineages; formal subtribe Quediina mixes at least two relatively basal groups, ‘Quediina propria’ and ‘southern Quediina’; specialized subtribe Amblyopinina is an internal clade within ‘southern Quediina’; a relatively deeply nested ‘Staphylinini propria’ that unites current subtribes Staphylinina, Eucibdelina, Anisolinina, Xanthopygina and Philonthina is well supported as a monophyletic group. In strong contrast with morphology, molecular data place the tribes Othiini and Xantholinini nested within Staphylinini. Molecular results strongly conflict with morphology by uniting morphologically very different genera Holisus and Atanygnathus in one clade that has uncertain position within Staphylinini. Consistently with the most congruent areas of the morphology‐ and molecular‐based phylogenies, taxonomic changes are implemented for the formal subtribes Quediina and Amblyopinina.
