AbstractAn update of the delimitation of the genus Bruggmanniella based on phylogenetic analysis using morphological data is presented. We included the seven new species of Bruggmanniella described between 2019 and 2020, and discuss some aspects of the evolutionary changes among the closely related genera Bruggmanniella, Pseudasphondylia, and Illiciomyia. Bruggmanniella is confirmed here as a monophyletic Neotropical lineage, divergent from the Asian species. The phylogenetic reconstruction hypothesized here reinforces the pertinence of the genus Odontokeros to house all species occurring in the Oriental/Palearctic region under Bruggmanniella. The delimitation of Bruggmanniella, the geographical distribution, and niche occupation are discussed.

A New Species

In May 2020, a new taxon of Euphorbia, Euphorbiaceae was collected from a dry hillside of Dongsheng District, Ordos City, Inner Mongolia. The morphological characteristics of the specimens analyzed differ from those of the known Euphorbia species from this region; therefore, we suspected this may be a new species, and we set to analyze the ITS2 sequences of some Euphorbia species. The results show that the new taxon belongs to the sect. Esula of Euphorbia subg. Esula. It is similar to Euphorbia esula (description from Flora of China) but does not belong to the same species. Concomitantly, plant morphological data and pollen morphology results show significant differences between the new taxon, E. esula and E. caesia, a finding that supports the delimitation of this new taxon, which is named Euphorbia mongoliensis in accordance with its geographical distribution.

A New Species

This report provides a description of Primula sunhangii from the Shennongjia Forestry District, Hubei Province in Central China, which is categorized as a new species of the primrose family. Primula sunhangii is morphologically similar to P. involucrata Wall. ex Duby in terms of its simple umbel, efarinose, and prolonged bracts. However, P. sunhangii is distinguished by its glabrous sepal, short petiole (compare with blade) and cylindrical calyx and capsule. Molecular phylogenetic analysis based on nuclear and cpDNA genes demonstrates that P. sunhangii and P. involucrata are closely related. Combining genetic and morphological data, the recognition of P. sunhangii as a unique new species is supported.

This study examined 504 Rhabdoblatta specimens sampled from China, of which, 86 Rhabdoblatta specimens were used for COI sequencing. A phylogenetic analysis using the ML method and MOTUs estimations by ABGD and GMYC based on COI sequences was performed. Eighteen Rhabdoblatta species were identified when these data were combined with morphological data. Six new species were established among these samples, i.e., Rh.similsinuatasp. n., Rh.densimaculatasp. n., Rh.gyroflexasp. n., Rh.chaulformissp. n., Rh.maculatasp. n., and Rh.ecarinatasp. n. For the first time, females including female genitalia of 14 known Rhabdoblatta species are described worldwide. Our study shows that combining molecular species delimitation methods with morphological data helps to delimit species and understand cockroach biodiversity.

Pristimantis, distributed throughout the New World tropics, is the most speciose vertebrate genus. Pristimantis presents an enormous morphological diversity and is currently divided into several demonstrably non-monophyletic phenetic species groups. With the purpose of increasing our understanding of Pristimantis systematics, we present the first phylogenetic analysis using molecular evidence to test the monophyly and infer evolutionary relationships within the Pristimantis leptolophus group, an endemic group of frogs from the highlands of the Colombian Andes. Our phylogenetic reconstruction recovers the group as monophyletic with high support, indicating general concordance between molecular data and morphological data. In addition, we describe a new polymorphic species lacking conspicuous tubercles, a regular attribute among species of the P. leptolophus species group and endemic from the Páramo de Sonsón complex (Antioquia, Colombia). The phylogenetic position of the new species is inferred and other systematic implications in the light of our results are discussed.

A new genus of Neotropical Lycidae, Currhaeus gen. nov., is herein proposed as the second Eurrhacini genus lacking parameres in male genitalia. Seven new species are described: Currhaeus striatus sp. nov., C. nigroapicalis sp. nov., C. championi sp. nov., C. tabascensis sp. nov., C. ruschii sp. nov., C. polegattoi sp. nov., and C. paranaensis sp. nov. Illustrations of diagnostic characters and a key to species identification are presented. Parsimony and maximum likelihood analyses of morphological data demonstrated that Currhaeus gen. nov. belongs in the crown Eurrhacini. Implied weighting parsimony trees recovered Currhaeus as sister to Eurrhacus Waterhouse.

A New Species

Here we describe Oxytropis shennongjiaensis, a new species of Fabaceae from Central China (Hubei Province). Morphologically, O. shennongjiaensis is closely similar to O. sitaipaiensis, O. melanocalyx and O. kansuensis, but differs in stem characters, with less conspicuous internodes; persistent herbaceous stipules; pale yellow to white corolla; and stipitate legumes, 3–5 mm with a long beak. Phylogenetic analysis, based on the internal transcribed spacers (ITS) and two chloroplast markers (trnL–F and psbA–trnH), also identified O. shennongjiaensis as a new species, which is consistent with our morphological analyses. Considering the morphological data and phylogenetic data presented here, we believe that this evidence satisfies the required diagnostic criteria to identify O. shennongjiaensis as a new species.

This study represents the first phylogenetic reconstruction of lumbrinerid genera using parsimony analyses of 38 morphological characters. Following higher-level phylogenetic analysis, Oenone (Oenonidae) was selected as outgroup. The analysis was restricted to type species for each genus, yielded 24 equally parsimonious trees, which after successive weighting were reduced to one tree (CI= 0.7396). The topology of this tree revealed the separation of the family into four main clades: 1. Lysarete, 2. Arabellonereis, 3. Scoletoma, Lumbrineris, Hilbigneris gen. nov., Kuwaita, Lumbricalus, Sergioneris gen. nov. and Eranno, and 4. Abyssoninoe, Cenogenus, Lumbrinerides, Lumbrineriopsis, Augeneria, Loboneris gen. nov., Gallardoneris gen. nov., Helmutneris gen. nov., and Gesaneris gen. nov.; the position of Ninoe is unclear. A diagnosis of each genus is provided, including the description of six new genera and three new species. A key to lumbrinerid genera is included.

Six new species are described as males: P. (Pe.) botiense, P. (Pe.) botosaneanui, P. (Pe.) camposense, P. (Pe.) intuber, P. (Pe.) reei, and P. (Pe.) tissamaharense. One additional species is described as female imago. P. (Pe.) pseudotritum and P. (Pe.) utonaiprimum are synonyms of P. (Pe.) tigrinum, and P. (Pe.) takorageheum and P. (Pe.) famibeceum synonyms of P. (Pe.) furusecundum. Five species misidentified as Pentapedilum and one as Polypedilum s. str. have been transferred, four to Polypedilum s. str. [P. (P.) inaijeum Sasa, Kitami et Suzuki, P. (P.) iriodeeum Sasa et Suzuki, P. (P.) jokasecundum Sasa et Ogata, and P. (P.) parasordens Ree], one to Ainuyusurika [A. yakuabeum (Sasa et Suzuki)] and one to P. (Uresi- pedilum). P. (Pe.) pseudotritum and P. (Pe.) utonaiprimum are synonymized with P. (Pe.) tigrinum, and P. (Pe.) tokarageheum and P. (Pe.) famibeceum synonymized with P. (Pe.) furudosecundum. Subgeneric diagnoses are given for all stages and sexes of the subgenus Pentapedilum Kieffer. Keys are provided for all stages and sexes of all available material from all zoogeographical regions. The phylogenetic analysis, which included some species of Polypedilum s. str. and all available Pentapedilum indicate that Pentapedilum is likely monophyletic, while Polypedilum s. str. is polyphyletic. The subgenus Pentapedilum can be divided into three relatively distinct apical groups and the remaining species in a basal Hennigian comb when a parsimony analysis is done. The convexum group consists of one Afrotropical species, and five High, East and South Asian species with one of them also occurring in the Indo-Pacific. The sordens group consists of 13 species from Asia, the Indo-Pacific and Africa. The apparently paraphyletic uncinatum group consists of 9 species from the Holarctic and Oriental regions. The zoogeographical distribution does not support any vicariance patterns, but indicates that the present distribution is caused by dispersal. Diagnostic characters and keys to the males of Ainuyusurika Sasa et Shirasaki is given and Pentapedilum yakuabeum Sasa et Suzuki and Polypedilum (P.) yakucedeum Sasa et Suzuki assigned to the genus. The genus appears to be close to Phaenopsectra Kieffer and is known from Japan only.

A New Species

Aster brevicaulis W. P. Li (Asteraceae, Astereae), a new species from Sichuan, China, is illustrated and described. Morphological data and a phylogenetic analysis based on a combined nuclear DNA ITS and ETS dataset suggest that A. brevicaulis is a separate species closely related to A. tongolensis. The new species differs from the latter by having stems only 2–15 (22) cm long, without stolons, phyllaries 5-seriate, and pappus 4–5 mm long. Cytological observation shows that the new species is diploid with 2n = 2x = 18 =16m + 2sm.
