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.     

Large-scale diversity reassessment,evolutionary history,and taxonomic revision of the green macroalgae family Udoteaceae (Bryopsidales,Chlorophyta)

Udoteaceae is a morphologically diverse family of the order Bryopsidales. Despite being very widespread geographically, this family is little known as compared with the closely related Halimedaceae or Caulerpaceae. Using the most extensive Udoteaceae collection to date and a multilocus genetic data set (tufA, rbcL, and 18S rDNA), we reassessed the species diversity of the family, as well as the phylogenetic relationships, the diagnostic morphoanatomical characters, and evolutionary history of its genera, toward a proposed taxonomic revision. Our approach included a combination of molecular and morphological criteria, including species delimitation methods, phylogenetic reconstruction, and mapping of trait evolution. We successfully delimited 62 species hypotheses, of which 29 were assigned (existing) species names and 13 represent putative new species. Our results also led us to revise the genera Udotea s.s., Rhipidosiphon s.s., and Chlorodesmis s.s., to validate the genus Rhipidodesmis, and to propose three new genera: Glaukea gen. nov., Ventalia gen. nov., and Udoteopsis gen. nov. We also identified two large species complexes, which we refer to as the “Penicillus–Rhipidosiphon–Rhipocephalus–Udotea complex” and the “Poropsis–Penicillus–Rhipidodesmis complex”. Using a time-calibrated phylogeny, we estimated the origin of the family Udoteaceae at Late Triassic (ca. 216 Ma), whereas most of the genera originated during Paleogene. Our morphological inference results indicated that the thallus of the Udoteaceae ancestor was likely entirely corticated and calcified, composed of a creeping axis with a multisiphonous stipe and a pluristromatic flabellate frond. The frond shape, cortication, and calcification are still symplesiomorphies for most extant Udoteaceae genera and represent useful diagnostic characters.     

Morphological classification of loaches (Nemacheilinae)

Comprehensive comparative morphological analysis of loaches from the subfamily Nemacheilinae is conducted. Forty significant phylogenetic characters are suggested, and phylogenetic relationships are reconstructed. The subfamily Nemacheilinae is subdivided into five tribes (Vaillantellini, Lefuini nov., Yunnanilini nov., Triplophysini nov., and Nemacheilini), and the relationships between these tribes can be expressed by the following formula: Vaillantellini (Lefuini (Yunnanilini (Triplophysini + Nemacheilini))). The classification of highland Asian loaches (Triplophysini) is specified, and the revised diagnoses of the genera from this tribe are given. Heterogeneity of the genus Triplophysa is demonstrated. This genus can be divided into several subgenera, and three new subgenera (Labiatophysa subgen. nov., Indotriplophysa subgen. nov., and Tarimichthys subgen. nov.) are described. A new species Hedinichthys grummorum sp. n is described from the Turpan Depression (northwest China).     

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.     

A micromorphological study of some representative genera in the tribe Saturejeae (Lamia ceae)

HUSAIN, S. Z., MARIN, P. D., ŠILIĆ, Č., QAISER, M. & PETCOVIĆ, B., 1990. A micromorphological study of some representative genera in the tribe Saturejeae (Lamiaceae). The Old World genera in the tribe Saturejeae are usually distributed either in Europe and North Africa or in the temperate parts of Asia. The centres of distribution of investigated genera are mainly in the Mediterranean region. In taxonomic revisions very little reference is made to micromorphological characters, in particular, to nutlets and leaf indumentum, in spite of the stability of these characters. Scanning electron microscopy of nutlet surface and patterns of leaf indumentum show a wide range of variation, not only among genera, but also at lower levels of classification. In view of this, nutlet surface and leaf indumentum structure, as seen with the SEM, of representative species of eight genera in the tribe Saturejeae provides useful additional character combinations in delimiting these closely related genera. This study also supports Boissier's delimitation of sections Micromeria and Pseudomelissa.     

Molecular systematics of Boraginaceae tribe Boragineae based on ITS1 and trnL sequences, with special reference to Anchusa s.l

BACKGROUND AND AIMS: Boragineae is one of the main tribes of Boraginaceae, but delimitation and intergeneric classification of this group are unclear and have not yet been studied using DNA sequences. In particular, phylogenetic relationships in Anchusa s.l. still need to be elucidated in order to assess its taxonomic boundaries with respect to the controversial segregate genera Hormuzakia, Gastrocotyle, Phyllocara and Cynoglottis. METHODS: Phylogenetic relationships among 51 taxa of tribe Boragineae were investigated by comparative sequencing of the trnL(UAA) intron of the plastid genome and of the ITS1 region of the nuclear ribosomal DNA. Exemplar taxa from 16 genera of Boragineae and all subgenera of Anchusa s.l. were included, along with two selected outgroups from tribes Lithospermeae and Cynoglosseae. KEY RESULTS: Phylogenies generated by maximum parsimony and combined ITS1-trnL sequences support the monophyly of the tribe and a split into two clades, Pentaglottis and the remainder of Boragineae. The latter contains two large monophyletic groups. The first consists of three moderately to well-supported branches, Borago-Symphytum, Pulmonaria-Nonea and Brunnera. In the Pulmonaria-Nonea subclade, the rare endemic Paraskevia cesatiana is sister to Pulmonaria, and Nonea appears to be paraphyletic with respect to Elizaldia. The second main group corresponds to the well-supported clade of Anchusa s.l., with the megaphyllic, polyploid herb Trachystemon orientalis as sister taxon, although with low support. Anchusa s.l. is highly paraphyletic to its segregate genera and falls into four subclades: (1) Phyllocara, Hormuzakia, Anchusa subgenus Buglossum and A. subgenus Buglossoides; (2) Gastrocotyle; (3) A. subgenus Buglossellum and Cynoglottis; and (4) A. subgenus Anchusa, Lycopsis and Anchusella. All species of Anchusa subg. Anchusa, including the South African A. capensis, are included in a single unresolved clade. Anchusa subgenus Limbata is also included here despite marked divergence in floral morphology. The low nucleotide variation of ITS1 suggests a recent partly adaptive radiation within this group. CONCLUSIONS: Molecular data show that nine of the usually accepted genera of the Boragineae consisting of two or more species are monophyletic: Anchusella, Borago, Brunnera, Cynoglottis, Gastrocotyle, Hormuzakia, Nonea, Pulmonaria and Symphytum. In addition, the tribe includes the four monotypic genera Paraskevia, Pentaglottis, Phyllocara and Trachystemon. The morphologically well-characterized segregate genera in Anchusa s.l. are all confirmed by DNA sequences and should be definitively accepted. Most of the traditionally recognized subgenera of Anchusa are also supported as monophyletic groups by both nuclear and plastid sequence data. In order to bring taxonomy in line with phylogeny, the institution of new, independent generic entities for subgenera Buglossum, Buglossellum and Buglossoides and a narrower but more natural concept of Anchusa are advocated.     

Systematic revision of Aluntiini Emeljanov, 1979 (Hemiptera: Fulgoromorpha: Dictyopharidae: Dictyopharinae): reclassification,phylogenetic analysis,and biogeography

The dictyopharid planthopper tribe Aluntiini s.l. is revised and reclassified into two tribes: Aluntiini s.s. and Arjunini Song & Szwedo trib. nov. The tribe Aluntiini s.s. includes five genera: Aluntia Stål, 1866; D endrophora Melichar, 1903 stat. rev. ; Dictyomorpha Melichar, 1912; Indodictyophara Liang & Song, 2012; and Madagascaritia Song & Liang gen. nov. The new tribe Arjunini comprises two genera – Arjuna Muir, 1934 and Pippax Emeljanov, 2008 – both moved from Aluntiini s.l. Four new species – A luntia longicephalica Song & Szwedo sp. nov. , Madagascaritia angusta Song & Liang sp. nov. , Arjuna maai Song & Wang sp. nov. , and Arjuna muiri Song & Wang sp. nov. – are described. A morphologically based phylogenetic analysis is undertaken for Aluntiini, Arjunini, and the representatives of Dictyopharini, Hastini, Orthopagini, and the fossil Worskaitini within Dictyopharinae, all distributed in the Old World. A matrix of 129 characters of the habitus, coloration, head, thorax, and male and female genitalia of the adults was used for the cladistic analysis. The phylogenetic results show that Aluntiini s.l. as placed in Dictyopharidae is well supported, but it is distinctly paraphyletic and should be separated into two unambiguous tribes. A palaeotropical distribution pattern displayed by Aluntiini is suggested. The origin and diversification of Aluntiini are discussed preliminarily. © 2015 The Linnean Society of London     

Monophyly and systematic position of Glypthelmins (Digenea), based on partial lsrDNA sequences and morphological evidence

Species composition and systematic placement within the order Plagiorchiida has been controversial. Species number in Glypthelmins Stafford, 1905, a genus of cosmopolitan parasites of anurans, has varied between 19 and 28 species, depending on the taxonomic treatment. The present study performs a phylogenetic analysis using partial lsrDNA sequences to test the monophyly of the genus, and compares new sequences obtained with those published for different plagiorchiids to clarify the systematic position of Glypthelmins within the order Plagiorchiida. Maximum parsimony (MP) and maximum likelihood (ML) analyses result in identical tree topology. The single MP tree (L=1587, CI=0.40, RI=0.76) includes several clades with high bootstrap and Bremer support values. Glypthelmins sensu lato as traditionally classified is paraphyletic. Based on molecular and/or morphological evidence, the taxonomic diagnosis for Glypthelmins is emended, only eight species are retained in the genus, and re-establishment of the genera Choledocystus Pereira & Cuocolo, 1941 and Rauschiella Babero, 1951 is proposed, resulting in the following new combinations: Choledocystus simulans (Teixeira de Freitas, 1941) comb. nov., C. vitellinophilum (Dobbin, 1958) comb. nov.; Rauschiella chaquensis (Mañé-Garzón & Holcman-Spector, 1967) comb. nov., R. lenti (Teixeira de Freitas, 1941) comb. nov., R. linguatula (Rudolphi, 1819) comb. nov., R. poncedeleoni (Razo-Mendivil & León-Règagnon, 2001) comb. nov., R. robusta (Brooks, 1976) comb. nov., R. rugocaudata (Yoshida, 1916) comb. nov., R. staffordi (Tubangui, 1928) comb. nov. In the phylogenetic reconstruction, Glypthelmins sensu stricto forms the sister group of Haematoloechus Looss, 1899.     

A Revision of Subtribe Pleioblastinae Keng & Keng f.

This paper deals with the taxa of tribe Arundinarieae Steud. subtribe Pleiobalastinae Keng and Keng f. which comprised three genera (Pseudosasa Makino, Pleioblastus Nakai and Brachystachyum Keng) when it was established in 1957. With the analysis of morphological characters and geographical distribution, a number of revisions connected with the taxon are made as follows: (1) Genus Brachystachyum Keng is transferred to the tribe Shibataeeae Nakai according to its false inflorescence. (2) Genus Pseudosasa Makino is transferred to subtribe Sasinae Keng f. according to our study on the numerical taxonomic method. (3) Some species of Pleioblastus Nakai established by Keng and Keng f. should be revised. Pleioblastus actinotrichus (Merr. and Chun) Keng f. should be Ampelocalamus actinotrichus (Merr. and Chun) S. L. Chen, T. H. Wen and G. Y. Sheng in subtribe Thamnocalaminae Keng f.; Pleioblastus dolichanthus (Keng) Keng f. is the synonym of Sinobambusa tootsik (Sieb.) Makino, belonging to tribe Shibataeeae Nakai. The rest species remain in this genus. Since the genus Pleioblastus is related to genus Arundinaria Michaux., subtribe Pleioblastus Keng and Keng f. does not seem to have a reason to be retained as a subtribe in tribe Arundinarieae Steud., according to the newest Code (1978). A part of it should be a synonym of subtribe Arundinariinae and we may cite it as follows: Subtribe Arundinariinae——Subtribe Pleioblastinae Keng and Keng f. pro parte, syn. nov. The other parts of it should be transferred to other subtribes or tribes. In addition, one new variety in Branchystachyum, two new species, one new variety in Pseudosasa and six new species, three new varieties in Pleioblastus, are described in this paper.     

The higher classification of the ant subfamily Leptanillinae (Hymenoptera: Formicidae)

Abstract. Until now the ant subfamily Leptanillinae has been closely linked with the army ant subfamilies Dorylinae and Ecitoninae, but on relatively tenuous evidence. The current phylogenetic study strongly indicates that this view is incorrect and that the leptanillines really constitute the sister-group of subfamily Ponerinae, and are at a consider- ably greater taxonomic distance from the Army Ant subfamilies. Three tribes are now recognized within the Leptanillinae (Leptanillini; Anomalornyrmini, new tribe; and Apomyrmini, transferred here from Ponerinae: Arnblyoponini), containing a total of eight genera with fewer than fifty species in all. The subfamily and its component tribes are diagnosed and discussed here, and a key to genera provided. New taxa described include Anomalomyrma Taylor gen.n., type-species A. taylori Bolton sp.n. and Protanilla Taylor gen.n., type-species P. rafflesi Taylor sp.n.     

Integrative taxonomy and phylogeny of leafless Vanilla orchids from the South-West Indian Ocean region reveal two new Malagasy species

The leafless Vanilla species complex from the South-West Indian Ocean (SWIO) region has long been a taxonomic challenge, due to limited patterns of morphological differentiation and an absence of variation within chloroplast sequences. This complex includes seven known morphospecies: V. madagascariensis, V. bosseri, V. decaryana, and V. perrieri endemic to Madagascar, V. humblotii presumed as endemic to the Comoros Archipelago, but also present in Madagascar, V. roscheri from the East African coast, and V. phalaenopsis endemic to Seychelles. A previous population genetic study using microsatellite markers allowed us to distinguish, in addition to the five recognized Malagasy taxa, two other genetic clusters present in the East of the island. An integrative taxonomy approach was therefore conducted by combining microsatellite and morphological data used in the previous study with new data sets, and by adding ITS sequencing data, to validate the taxonomic level of these Malagasy genetic clusters and unravel phylogenetic relationships between SWIO species. As a result, based on phylogenetic, genotypic and morphological evidence, nine species were discriminated in the SWIO region, including seven in Madagascar, with two new eastern species. The leafless Vanilla group originated and diversified in Madagascar, from an ancestor of African descent, with three subsequent independent colonization events from Madagascar to the other territories of SWIO within the two main lineages (white versus yellow flower species). The new Malagasy species, V. allorgeae Andriamihaja & Pailler sp. nov., and V. atsinananensis Andriamihaja & Pailler sp. nov., are described and a new identification key is proposed.     

Phylogenetic analyses confirm polyphyly of the genus Campanula (Campanulaceae s. str.), leading to a proposal for generic reappraisal

Previous phylogenetic analyses found that the largest genus in the tribe Campanuleae, Campanula L. is polyphyletic. The genus is extremely intermingled, involving more than 50 genera, but no generic reappraisal has been attempted. For undertaking further phylogenetic analyses and subsequent generic reappraisal of the tribe, we sampled 333 samples, representing 27 of 28 genera currently recognized. Among them, 146 samples and two genera, Cylindrocarpa Regel and Sergia Fed., were newly sequenced. Six chloroplast DNA loci (atpB-rbcL, matK, petD-intron, rbcL, rpl16, and trnL-F) and internal transcribed spacer were used to undertake phylogenetic analyses. Our chloroplast DNA phylogeny comprises 24 clades, that is, 18 Cam clades and six genera, Feeria Buser, Homocodon D. Y. Hong, Jasione L., Peracarpa Hook. f. & Thomson, Trachelium L., and Favratia Feer. Campanula species are scattered among the 18 Cam clades and the six genera, and some of them join with well-established genera like Phyteuma L. and Adenophora Fisch. In the phylogeny Musschia Dumort. is at the basal position, but Jasione's position is unclear, whether in the tribe Campanuleae or in Wahlenbergieae; the other 22 lineages are grouped into two major clades: clade A comprising Cam 13–17 plus Feeria and Trachelium, and clade B comprising Cam 02, 03, 04-1, 04-2, and 06-12 plus Homocodon and Peracarpa. We found that the molecular phylogeny is closely correlated with morphology, particularly pollen morphology: clade A with pollen 3-porate and capsule dehiscent mostly by basal pores; and clade B with pollen mostly 4 (5–15)-porate and capsule dehiscent mostly by apical-middle pores. A generic reappraisal of the tribe is suggested based on the integrated phylogenetic analyses.     

Tetrablemmidae (Arachnida, Araneae), a spider family newly recorded from China

The family Tetrablemmidae is reported for the first time from China, with five new species and one new genus. Lehtinenia gen. n., which is erected to accommodate Lehtinenia bicornis sp. n., is characterized by the modified embolus, special modifications on chelicerae, and a Tetrablemma-type vulva. The other four new species are: Ablemma prominens sp. n., Brignoliella caligiformis sp. n., Brignoliella maoganensis sp. n., and Tetrablemma brevidens sp. n., all collected from caves. A phylogenetic analysis of the subfamily Tetrablemminae based on 41 morphological characters shows that the tribe Brignoliellini is the most basal group in the subfamily, rather than the sister group to the tribe Fallablemmini. Lehtinenia gen. n. and the genera Ablemma, Sulaimania, and Maijana together form a monophyletic group.     

A reassessment of tribal affinities of Cratystylis and Haegiela (Asteraceae) based on three chloroplast DNA sequences

 The tribal affinities of Cratystylis and Haegiela were assessed using three chloroplast DNA sequences, the trnL/F spacer, the trnL intron and the matK coding region. The outgroup was represented by two species of the subfamily Barnadesioideae, whereas one to seven genera (45 species including Cratystylis and Haegiela) of the tribes of the Asteroideae [Anthemideae (6 genera), Astereae (7), Calenduleae (2), Gnaphalieae (7), Heliantheae s.l. (5), Inuleae s.str. (3), Plucheeae (3), Senecioneae (4)] and Cichorioideae, [Arctotideae (1), Cardueae (2), Lactuceae (2), Liabeae (1), Mutisieae (1) and Vernonieae (1)] comprise the ingroup. Phylogenetic analysis indicates that Cratystylis has strong support as a member of the tribe Plucheeae, whereas Haegiela is a member of Gnaphalieae. At some point in their taxonomic history, both genera have been placed in these tribes and there are good morphological and chemical characters that justify these placements. The monotypic Haegiela was once included in Epaltes (Plucheeae) and this study has confirmed the need for the separation of the two genera. The genus Cratystylis appears to be monophyletic.

A new phylogenetic tribal classification of the grape family (Vitaceae)

Vitaceae (the grape family) consist of 16 genera and ca. 950 species primarily distributed in tropical regions. The family is well‐known for the economic importance of grapes, and is also ecologically significant with many species as dominant climbers in tropical and temperate forests. Recent phylogenetic and phylogenomic analyses of sequence data from all three genomes have supported five major clades within Vitaceae: (i) the clade of Ampelopsis, Nekemias, Rhoicissus, and Clematicissus; (ii) the Cissus clade; (iii) the clade of Cayratia, Causonis, Cyphostemma, Pseudocayratia, Tetrastigma, and an undescribed genus “Afrocayratia”; (iv) the clade of Parthenocissus and Yua; and (v) the grape genus Vitis and its close tropical relatives Ampelocissus, Pterisanthes and Nothocissus, with Nothocissus and Pterisanthes nested within Ampelocissus. Based on the phylogenetic and morphological (mostly inflorescence, floral and seed characters) evidence, the new classification places the 950 species and 16 genera into five tribes: (i) tribe Ampelopsideae J.Wen & Z.L.Nie, trib. nov. (47 species in four genera; Ampelopsis, Nekemias, Rhoicissus and Clematicissus); (ii) tribe Cisseae Rchb. (300 species in one genus; Cissus); (iii) tribe Cayratieae J.Wen & L.M.Lu, trib. nov. (370 species in seven genera; Cayratia, Causonis, “Afrocayratia”, Pseudocayratia, Acareosperma, Cyphostemma and Tetrastigma); (iv) tribe Parthenocisseae J.Wen & Z.D.Chen, trib. nov. (ca. 16 spp. in two genera; Parthenocissus and Yua); and (v) tribe Viteae Dumort. (ca. 190 species in two genera; Ampelocissus and Vitis).
