Phylogeny and tribal classification of Sterrhinae with emphasis on delimiting Scopulini (Lepidoptera: Geometridae)

Abstract. The phylogenetic relationships of tribes of the geometrid subfamily Sterrhinae (Lepidoptera) were studied, with special emphasis on finding delimiting characters for the tribe Scopulini. Two cladistic analyses were conducted for fifty‐nine species representing all previously recognized Sterrhinae tribes and covering the geographical range of the subfamily. In the first analysis, twelve putative synapomorphies of Scopulini, taken from the literature, were coded for actual specimens in order to test their ability to support the monophyly of the group. The resulting strict consensus cladogram was totally unresolved. In the second analysis, the twelve characters were combined with additional information from the morphology and ecology of adults and immature stages. Analysis of these ninety‐six characters resulted in a well‐resolved cladogram. The tribes were found to be monophyletic, except Cosymbiini and Rhodostrophiini. There are two main lineages within Sterrhinae: Cosymbiini + Rhodometrini + Timandrini and Rhodostrophiini + Cyllopodini + Sterrhini + Scopulini. Aletini and Problepsini lay within the concept of Scopulini. The association of the included Larentiinae taxa with the Cosymbiini + Rhodometrini + Timandrini lineage questions the monophyly of Sterrhinae. A majority of the recovered synapomorphic characters had been recognized previously, but several new phylogenetically informative characters were found, especially from the thorax. No unique characters diagnosing the tribe Scopulini were found, but many homoplastic synapomorphic features were found which diagnose parts of it. All recognized Sterrhinae genera are assigned tentatively to tribes and problematic cases are discussed.     

Phylogeny,classification and biogeography of bombyliine bee flies (Diptera,Bombyliidae)

The Bombyliinae comprises over 1100 described species in 73 known genera distributed worldwide. It is one of the largest subfamilies of bee flies (Diptera: Bombyliidae). We present the first phylogenetic hypothesis for this subfamily, based on 157 adult morphological characters scored for 123 species representing 60 genera, including all the tribes of Bombyliinae, and the related subfamilies Lordotinae and Toxophorinae. Four most parsimonious trees were generated from our analysis under equal weighting schemes. The monophyly of Bombyliinae is supported, and Lordotinae is sister to the Bombyliinae. Within Bombyliinae, Conophorini is sister to the remaining tribes. Five previously recognized tribes are revised and four new tribes are erected. We placed almost all genera in our tribal classification, based on our phylogenetic results and available character evidence. The genus Parabombylius is proposed as a synonym of Bombylius. The Gondwanan origin for the major lineages of Bombyliinae is strongly indicated by our biogeographic analysis which reconstructs ancestral areas.

Phylogeny and classification of the Scopulini moths (Lepidoptera: Geometridae, Sterrhinae)

The phylogenetic relationships of the genera in the geometrid tribe Scopulini (Lepidoptera: Sterrhinae) were examined using 141 characters of adult morphology and ecology. The study material included 92 species, representing all previously recognized genera and covering the morphological variation and full geographical range of the tribe. The cladistic analysis resulted in 20 equally parsimonious trees and a strict consensus cladogram based on these was well resolved. A majority of the recovered synapomorphic characters have been used previously in the taxonomy of the tribe. However, many novel characters were found in the sclerotized structures of the thorax. Many previously recognized genera were found to be nonmonophyletic and based on the present revised, synapomorphy-based classification, the number of recovered genera is reduced considerably. Twenty new generic synonyms and 90 new or revived species combinations are proposed. Seven genera are considered valid, with the large genus Scopula Schrank including over 85% of all species in the tribe. The taxonomic history of the tribe is reviewed and the problems of earlier classifications are discussed. A key to the genera is presented, although an informal diagnosis is preferred. All recognized genera are illustrated and a revised world checklist of the Scopulini is presented.  © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society , 2005, 143 , 473−530.     

Phylogeny of the subfamily Larentiinae (Lepidoptera: Geometridae): integrating molecular data and traditional classifications

Larentiinae are the second largest subfamily of Geometridae, with more than 6200 described species. Despite recent advances in molecular systematics of geometrid moths, phylogenetic relationships between the numerous subgroups of Larentiinae are poorly known. In this study we present the most comprehensive attempt to date to resolve the phylogeny of Larentiinae, having sampled at least one species from all currently recognized 23 tribes. Fragments of one mitochondrial (COI) and eight nuclear (EF‐1α, WGL, GAPDH, RPS5, IDH, MDH, CAD and 28S) genes were sequenced, for a total of 6939 bp. Maximum likelihood and Bayesian analyses resulted in identical well‐resolved phylogenetic trees, which had maximum or near‐maximum support values at most nodes. Almost all conventionally recognized tribes represented by more than one genus were found to be monophyletic. Close to the root of Larentiinae, six tribes branch off the main lineage one after another, with Dyspteridini being sister to all other members of the subfamily. The rest of larentiines are divided into two very diverse lineages, comprising eight and at least ten tribes, respectively. There were just three findings incongruent with the conventional tribal subdivision of the subfamily. First, the genera Collix Guenée and Anticollix Prout formed a separate, previously unrecognized but well‐supported clade at the tribe level. Second, the Palaearctic genus Pelurga Hübner was placed apart from Larentia Treitschke and Mesoleuca Hübner, which were the other members of Larentiini in this analysis. Third, Cataclysmini appeared together with genera belonging to Xanthorhoini, leaving the latter paraphyletic. The Neotropic genus Oligopleura Herrich‐Schäffer is shown to belong to the tribe Euphyiini ( comb.n. ) according to both molecular data and male genital morphology. The results and the tribal classification of Larentiinae are discussed with reference to the principal publications since the end of the 19th Century. We conclude that the current tribal classification of Larentiinae is not controversial from the phylogenetic point of view and that its increasing complexity has merely reflected the accumulation of information, mainly through different methods of biosystematic study having become available for researchers. Our results indicate that diurnal lifestyle, accompanied by conspicuous coloration, has evolved independently in several subgroups of Larentiinae.     

Modern classification and distribution of the family Issidae Spinola (Homoptera,Auchenorrhyncha: Fulgoroidea)

The modern classification of the family Issidae s. str. is presented according to which the family consists of 3 tribes: Issini, Hemisphaeriini, and Parahiraciini and comprises a total of 994 species and subspecies in 159 genera. The largest tribe, Issini, is distributed worldwide and comprises 129 genera with 755 species and subspecies. The tribes Hemisphaeriini and Parahiraciini are much smaller and mostly distributed in the Indo-Malayan Realm with some taxa also present in the Eastern Palaearctic and the Oceania. The tribe Hemisphaeriini consists of 15 genera with 187 species and subspecies while Parahiraciini includes 14 genera with 38 species. The Palaearctic and Indo-Malayan Realms have the richest faunas of Issidae. In contrast, Equatorial Africa has a very poor fauna of the family, whereas the Australian fauna is still almost undescribed. Chimetopon camerunensis Schmidt is recorded for the first time from Central African Republic and Gabon, and Sarima erythrocyclos Fennah, from Taveuni Island (Fiji).     

A worldwide phylogenetic classification of the Poaceae (Gramineae) III: An update

We present an updated worldwide phylogenetic classification of Poaceae with 11 783 species in 12 subfamilies, 7 supertribes, 54 tribes, 5 super subtribes, 109 subtribes, and 789 accepted genera. The subfamilies (in descending order based on the number of species) are Pooideae with 4126 species in 219 genera, 15 tribes, and 34 subtribes; Panicoideae with 3325 species in 242 genera, 14 tribes, and 24 subtribes; Bambusoideae with 1698 species in 136 genera, 3 tribes, and 19 subtribes; Chloridoideae with 1603 species in 121 genera, 5 tribes, and 30 subtribes; Aristidoideae with 367 species in three generaand one tribe; Danthonioideae with 292 species in 19 generaand 1 tribe; Micrairoideae with 192 species in nine generaand three tribes; Oryzoideae with 117 species in 19 genera, 4 tribes, and 2 subtribes; Arundinoideae with 36 species in 14 genera and 3 tribes; Pharoideae with 12 species in three generaand one tribe; Puelioideae with 11 species in two generaand two tribes; and the Anomochlooideae with four species in two generaand two tribes. Two new tribes and 22 new or resurrected subtribes are recognized. Forty-five new (28) and resurrected (17) genera are accepted, and 24 previously accepted genera are placed in synonymy. We also provide an updated list of all accepted genera including common synonyms, genus authors, number of species in each accepted genus, and subfamily affiliation. We propose Locajonoa, a new name and rank with a new combination, L. coerulescens. The following seven new combinations are made in Lorenzochloa: L. bomanii, L. henrardiana, L. mucronata, L. obtusa, L. orurensis, L. rigidiseta, and L. venusta.     

First phylogeny of predatory flower flies (Diptera, Syrphidae, Syrphinae) using mitochondrial COI and nuclear 28S rRNA genes: conflict and congruence with the current tribal classification

The family Syrphidae (Diptera) is traditionally divided into three subfamilies. The aim of this study was to address the monophyly of the tribes within the subfamily Syrphinae (virtually all with predaceous habits), as well as the phylogenetic placement of particular genera using molecular characters. Sequence data from the mitochondrial protein-coding gene cytochrome c oxidase subunit I ( COI ) and the nuclear 28S ribosomal RNA gene of 98 Syrphinae taxa were analyzed using optimization alignment to explore phylogenetic relationships among included taxa. Volucella pellucens was used as outgroup, and representatives of the tribe Pipizini (Eristalinae), with similar larval feeding mode, were also included. Congruence of our results with current tribal classification of Syrphinae is discussed. Our results include the tribe Toxomerini resolved as monophyletic but placed in a clade with genera Ocyptamus and Eosalpingogaster . Some genera traditionally placed into Syrphini were resolved outside of this tribe, as the sister groups to other tribes or genera. The tribe Bacchini was resolved into several different clades. We recovered Paragini as a monophyletic group, and sister group of the genus Allobaccha . The present results highlight the need of a reclassification of Syrphinae.

A modern classification of the family Caliscelidae Amyot et Serville (Homoptera,Fulgoroidea)

Recent changes in the classification of the family Caliscelidae Amyot et Serville are summarized. All the genera are attributed to tribes and subfamilies. Data on the distribution and the number of genera and species for each tribe are presented. The subfamily Ommatidiotinae is shown to be absent in the recent New World fauna, and only the tribe Peltonotellini represents the subfamily Caliscelinae in the Nearctic and Neotropical regions.     

Multilocus phylogeny defines a new classification of Staphylininae (Coleoptera,Staphylinidae), a rove beetle group with high lineage diversity

We provide the first multilocus molecular phylogeny of a group corresponding to the former subfamily Staphylininae. Results are corroborated by the morphological, biogeographical and palaeobiological evidence to serve as a baseline for an updated suprageneric classification. The former subfamily Staphylininae is proven to be a lineage sister to the monophyletic Paederinae and reclassified according to a robust phylogeny resolving a number of long-standing controversies. The subfamily Xantholininae (revised status) is reinstated to contain the tribes Xantholinini, Othiini, Maorothiini and Diochini. Subfamily Platyprosopinae (revised status) is reinstated for the tribes Platyprosopinini, Arrowinini and †Thayeralinini. For a highly peculiar genus Coomania Cameron, formerly in Diochini, a new subfamily Coomaniinae subfam.n. is established and the composition of Diochini (revised status) is changed accordingly. The subfamily Staphylininae (revised status) is reduced to contain the former tribe Staphylinini only. Elevating this mega-diverse tribe to the subfamily rank opened up an opportunity for its more fractional classification by raising several subtribes to the tribal level as follows: Acylophorini, Afroquediini, Amblyopinini, Antimerini, †Baltognathini, Cyrtoquediini, Erichsoniini, Hyptiomini, Indoquediini, Quediini and Tanygnathinini (revised status for all). As a result, the most species-rich tribe Staphylinini (revised status) is reduced to the more homogeneous lineage containing the subtribes Algonina, Anisolinina, Philonthina, Philothalpina, Staphylinina and Xanthopygina. Morphological synapomorphies and diagnostic characters supporting all newly defined higher taxa are provided.

Phylogenetic systematics of the colorful, cyanide-producing millipedes of Appalachia (Polydesmida, Xystodesmidae, Apheloriini) using a total evidence Bayesian approach

Here, we provide an exemplar-approach phylogeny of the xystodesmid millipede tribe Apheloriini with a focus on genus-group relationships-particularly of the genus Brachoria. Exemplars for the phylogenetic analysis were chosen to represent the maximum breadth of morphological diversity within all nominal genera in the tribe Apheloriini, and to broadly sample the genus Brachoria. In addition, three closely related tribes were used (Rhysodesmini, Nannariini, and Pachydesmini). Morphological and DNA sequence data were scored for Bayesian inference of phylogeny. Phylogenetic analysis resulted in polyphyletic genera Brachoria and Sigmoria, a monophyletic Apheloriini, and a "southern clade" that contains most of the tribal species diversity. We used this phylogeny to track morphological character histories and reconstruct ancestral states using stochastic character mapping. Based on the findings from the character mapping study, the diagnostic feature of the genus Brachoria, the cingulum, evolved independently in two lineages. We compared our phylogeny against prior classifications using Bayes factor hypothesis-testing and found that our phylogenetic hypothesis is inconsistent with the previous hypotheses underlying the most recent classification. With our preferred total-evidence phylogeny as a framework for taxonomic modifications, we describe a new genus, Appalachioria; supply phylogenetic diagnoses of monophyletic taxa; and provide a phylogeny-based classification for the tribe Apheloriini.     

Additions to the geometrid fauna (Lepidoptera: Geometridae) of Chile

Three species of geometrid moths are reported from the extreme North of Chile. All three are new for the Chilean fauna: Scopula umbilicata (Fabricius, 1794) (Sterrhinae), Cataspilates grisescens Warren, 1897, and Pero obtusaria Prout, 1928 (Ennominae).     

Phylogeny and morphological evolution of tribe Menispermeae (Menispermaceae) inferred from chloroplast and nuclear sequences

The Menispermaceae family contains ca. 72 genera with 450 species that are almost entirely tropical. Its phylogeny at the tribal level has never been examined using molecular data. Here we used DNA sequences of the chloroplast matK gene and trnL-F regions, and the nuclear ITS region to study the delimitation and position of the tribe Menispermeae within the family and its subtribal monophyletic groups. Family-wide phylogenetic analyses of the chloroplast data produced two strongly supported clades. The first clade contains two subclades: Coscinieae including Arcangelisia and Anamirta, and Tinosporeae sensu lato including Fibraureae, supported by morphological characters, such as traits of the cotyledon, stylar scar and embryo. The second clade consists of the tribes Menispermeae sensu DC. and Tiliacoreae Miers. All our analyses surprisingly recognized that tribe Menispermeae is not monophyletic unless tribe Tiliacoreae is included, suggesting that characters of cotyledon and stylar scar are very important for the infrafamilial classification, and that endosperm presence vs. absence was over-emphasized in traditionally tribal division of the family. Our topologies indicate a secondary loss of endosperm. The monophyly of two subtribes of the tribe Menispermeae, Stephaniinae and Cissampelinae, is supported by the cpDNA and ITS data, as well as by morphological characters, including aperture types and shapes, and colpal membrane features of pollen grains, and sepal number of male flowers. The Cocculinae was recognized as a paraphyletic group containing the remaining genera of the tribe Menispermeae.     

A new classification of Cyperaceae (Poales) supported by phylogenomic data

Cyperaceae (sedges) are the third largest monocot family and are of considerable economic and ecological importance. Sedges represent an ideal model family to study evolutionary biology due to their species richness, global distribution, large discrepancies in lineage diversity, broad range of ecological preferences, and adaptations including multiple origins of C₄ photosynthesis and holocentric chromosomes. Goetghebeur′s seminal work on Cyperaceae published in 1998 provided the most recent complete classification at tribal and generic level, based on a morphological study of Cyperaceae inflorescence, spikelet, flower, and embryo characters, plus anatomical and other information. Since then, several family-level molecular phylogenetic studies using Sanger sequence data have been published. Here, more than 20 years after the last comprehensive classification of the family, we present the first family-wide phylogenomic study of Cyperaceae based on targeted sequencing using the Angiosperms353 probe kit sampling 311 accessions. In addition, 62 accessions available from GenBank were mined for overlapping reads and included in the phylogenomic analyses. Informed by this backbone phylogeny, a new classification for the family at the tribal, subtribal, and generic levels is proposed. The majority of previously recognized suprageneric groups are supported, and for the first time, we establish support for tribe Cryptangieae as a clade including the genus Koyamaea. We provide a taxonomic treatment including identification keys and diagnoses for the 2 subfamilies, 24 tribes, and 10 subtribes, and basic information on the 95 genera. The classification includes five new subtribes in tribe Schoeneae: Anthelepidinae, Caustiinae, Gymnoschoeninae, Lepidospermatinae, and Oreobolinae.     

Closing the gaps: phylogenetic relationships in the Brassicaceae based on DNA sequence data of nuclear ribosomal ITS region

Sequence data from the nuclear encoded ribosomal internal transcribed spacer (ITS) region were used to determine monophyly of tribes, tribal limits, and tribal relationships of 96 so far unassigned or tentatively assigned genera (represented by 101 taxa/accessions) within the Brassicaceae. Maximum-parsimony and maximum-likelihood analyses of 185 ITS Brassicaceae sequences, which also included representatives of each of the 34 currently recognized tribes, supported the separate phylogenetic distinctness of these tribes and permitted the tribal assignment of all but 12 of the unassigned genera into tribal clades. The data support the recognition of eight new, well-resolved, uni- or oligogeneric tribes recognized herein as the Alyssopsideae [96% bootstrap support (BS); including the central and southwestern Asian Alyssopsis and Calymmatium], Asteae (100% BS; including the Mexican Asta), Eudemeae (97% BS; South American Brayopsis, Eudema, and Xerodraba), Kernereae (96% BS; European Kernera and Rhizobotrya), Notothlaspideae (100% BS; New Zealandic Notothlaspi), Oreophytoneae (100% BS; eastern African Oreophyton and southern European Murbeckiella), and Yinshanieae (100% BS; Chinese Yinshania), as well as the moderately supported Microlepidieae (75% BS; Australian Microlepidium and Carinavalva). Furthermore, the results fully support the recent findings that the tribes Schizopetaleae and Thelypodieae ought to be recognized as two distinct tribes instead of a single tribe, as well as provide some support for the re-establishment of the tribe Cremolobeae, bringing the total number to 44 tribes in the family. Nearly 92% (308) of the 336 genera in the family have been assigned to a tribe. The earlier-published Anastaticeae is taken here to replace the Malcolmieae.     

A molecular phylogeny and classification of Verbenaceae

? Premise of the study: Verbenaceae consist of trees, shrubs, lianas, and herbs distributed primarily in Latin America, where they occur in a wide array of ecosystems. A second center of diversity exists in Africa. Competing morphology-based classifications that rely on different traits conflict in significant ways. A broad phylogenetic study was undertaken to assess those classifications and to examine the historical geography of the family. ? Methods: Analysis of seven chloroplast DNA regions for 109 species, representing all genera except one monotypic genus, provide inference into evolutionary relationships in Verbenaceae. ? Key results: The phylogeny shows that none of the traditional classifications reflect phylogenetic relationships very well. Eight clades are recognized as tribes (Casselieae, Citharexyleae, Duranteae, Lantaneae, Neospartoneae trib. nov., Petreeae, Priveae, and Verbeneae). Two genera, Dipyrena and Rhaphithamnus, remain unplaced in these larger clades. Petreeae, which consist of Neotropical lianas, are sister to the rest of the family. Lantaneae and Verbeneae together form a derived clade that comprises approximately two-thirds of the species in Verbenaceae. ? Conclusions: We present a new tribal classification, including one new tribe, Neospartoneae trib. nov., to accommodate three small genera of Argentine species (Diostea, Neosparton, and Lampaya). Phylogenetic inference suggests a South American origin for Verbenaceae, with approximately six colonization events having given rise to the Old World species.     

The taxonomy and systematics of Apocynaceae: where we stand in 2012

In their most recent classification of Apocynaceae in 2000, Endress and Bruyns recognized five subfamilies of Apocynaceae (Rauvolfioideae, Apocynoideae, Periplocoideae, Secamonoideae and Asclepiadoideae). Subsequently, through various studies using molecular data, it has been shown that most tribes and subtribes of Rauvolfioideae were not monophyletic, and new tribes and subtribes have been erected to reflect improved phylogenetic understanding of the family: Aspidospermeae in Rauvolfioideae; Nerieae, Odontadenieae and Baisseeae in Apocynoideae; Fockeeae in Asclepiadoideae; and Orthosiinae in Asclepiadeae. Several genera in Rauvolfioideae have been reassigned to different tribes in order to improve the monophyly of these tribes. The sister group of Asclepiadoideae plus Secamonoideae is not Periplocoideae, as formerly assumed, but tribe Baisseeae. Periplocoideae are nested in Apocynoideae. However, tribal composition remains unclear in some parts of the family. Clade structure in Apocynaceae is now generally well understood. The principal challenges now lie in identifying characters that can reflect and articulate these clades in a formal classification. Species‐rich, recent radiations such as core Asclepiadinae in Africa and the Metastematinae in Latin America present particular problems in this regard. © 2013 The Linnean Society of London
