Sexual Form

A new sexual form of a gallwasp, Andricus forni Pujade-Villar & Nicholls n. sp., is described from China (Zhejiang province) based on males, females and galls collected on Quercus serrata. Data on the morphology, diagnosis, distribution and biology of the new species are provided. Molecular data are also provided to support this species. A key to Asian Andricus gallwasp species with similar integral leaf galls is presented. Finally we discuss the taxonomic status of Asian Andricus making these integral leaf galls, including uncertainty on the validity of both Andricus quercicola and A. marmoratus.

Background. Phrynops present four valid species, including P. geoffroanus that might represents a complex of cryptic species. Here, we provide a preliminary analysis of the taxonomy and phylogenetic affinities within Phrynops, with special reference to the taxonomic status of populations of P. geoffroanus and P. tuberosus, and the recognition of a new species from Southern Brazil. Methods. We studied populations from ten Brazilian river basins. A linear morphometric analysis was performed in order to define taxonomically distinct populations. Also, a phylogenetic analysis using morphology and molecular data (sequenced for the genes R35, RAG2, c-mos, cytb, ND4, and 12S) were carried out. Three distinct sets of phylogenetic analyses were performed: parsimony to morphological and combined data, and maximum likelihood to molecular data. Results. The combined analysis shows that Phrynops represents a well supported clade. The set of skeletal data supports Mesoclemmys as the sister group of Phrynops, whereas the molecular and combined data sets show Phrynops as the sister group of a clade composed by all the remaining genera of Chelidae, except Hydromedusa. Our morphological analyses suggest that P. hilarii is the sister group of P. geoffroanus, but in both molecular and combined analyses, P. hilarii appears nested within the clade formed by the populations of P. geoffroanus. Futhermore, P. tuberosus and P. geoffroanus are not distinguishable by the set of osteological and morphometric data. On the other hand, both morphometric and osteological data show that the population of P. geoffroanus from the Paraná river basin is a distinct species. Discussion. The sister group relationships of Phrynops could not be clearly defined due to the different topologies achieved. Phrynops hilarii is included within of P. geoffroanus in both molecular and combined data, but this position has little statistical support and therefore does not express a clear position of P. hilarii within the genus Phrynops. Besides, we were not able to distinguish P. geoffroanus and P. tuberosus. However, a sampling of specific locations are still needed to objectively define the taxonomic status of P. tuberosus. Finally, the population of P. geoffroanus from the Paraná basin is clearly distinct from the remaining populations of this species. Qualitative osteological characters and morphometric results seem to demonstrate that this population is a new species of Phrynops.

A New Species

The phylogenetic relationships of bandicoots and bilbies have been somewhat problematic, with conflicting results between morphological work and molecular data. This conflict makes it difficult to assess the taxonomic status of species and subspecies within this order, and also prevents accurate evolutionary assessments. Here, we present a new total evidence analysis, combining the latest cranio-dental morphological matrix containing both modern and fossil taxa, with molecular data from GenBank. Several subspecies were scored in the morphological dataset to match the molecular data available. Both parsimony and Bayesian analyses were performed, giving similar topologies except for the position of four fossil taxa. Total evidence dating places the peramelemorphian crown origin close to the Oligocene/Miocene boundary, and the radiations of most modern genera beginning in the Late Miocene or Early Pliocene. Our results show that some species and subspecies require taxonomic reassessment, and are revised here. We also describe a new, extinct species from the Nullarbor region. This suggests that the number of recently extinct peramelemorphian species is likely to further increase.

A New Species

Silene sunhangii, a new species of Caryophyllaceae known from only three populations in Hubei and Hunan provinces of central China, is described. Both morphological and molecular data were used to assess the taxonomic status and relationships of this species. Morphologically, S. sunhangii is most similar to S. platyphylla Franch. from which it differs most readily in having 3-veined elliptical leaves without pubescence, tasseled catacorolla, pale purple to red petals without a linear lobe or narrow tooth and lanceolate, bifid to one third. A phylogenetic analysis based on nuclear ITS region identified the new species as a well-supported, independent lineage. Our new species is nested within a grade that encompasses species representing a polyphyletic Silene sect. Physolychnis (Benth.) Bocquet. Both the genetic and morphological data support the recognition of Silene sunhangii as a distinct species, although there is inconsistency between these two datasets as to the relationships of the new species.

This study reports on new squat lobsters of the genus Munida collected during recent surveys of Australia’s continental margins. We report on 33 species of Munida including seven new species and 14 new range extensions for Australia. More than 500 specimens were collected, mostly from the western continental margin of Australia, but also including a new species from deep water (>2000 m) off Tasmania. We provide new data on the colour patterns of some species and include molecular data from two mitochondrial markers (16S rRNA and COI) to support the taxonomic status of the new species.

The taxonomic status of the previous record of Opisthotropis maculosa Stuart & Chuaynkern, 2007 from Guangdong and Guangxi, southern China, is revised based on the comparison of morphological and molecular data collected from the Chinese specimens and the holotype of O. maculosa from Thailand and O. haihaensis Ziegler, Pham, Nguyen, Nguyen, Wang, Wang, Stuart & Le, 2019 from Vietnam. Results reveal that the population from Shiwandashan Nature Reserve in southern Guangxi, China belongs to O. haihaensis, and represents the first national record for China; the populations from western Guangdong and southeastern Guangxi are described as a new species, Opisthotropis hungtaisp. nov. We suggest that O. maculosa should be removed from the Chinese herpetofauna checklist. The new national record of O. haihaensis and the description of the new species bring the total number of Opisthotropis to 13 in China.

A New Species

The genus Linum consists of 15 species in Iran. A new species as well as a new record from Iran is described and illustrated here as L. khorassanicum and L. turcomanicum, respectively. The original description of the latter species is incomplete and ambiguous, probably due to incomplete taxon sampling. In this work, after a comprehensive taxon sampling from the entire distribution range of the species in northeast of Iran, the taxonomic description of L. turcomanicum is completed. The present study considers morphological and molecular (the nrITS region) analyses of the both species. In phylogenetic analysis based on the molecular data, we included these species and some related Linum species to examine the phylogenetic relationship of the new species and L. turcomanicum with other members of the genus. Linum turcomanicum is morphologically almost similar to L. austriacum and L. perenne, but it can be distinguished from them on the basis of several traits such as fruiting-pedicel form and length of petal. Likewise, results obtained from the molecular phylogenetic tree are consistent with those obtained from the morphological data. Linum khorassanicum is well characterized morphologically by having erect fruiting pedicels and inflorescence with few flowers. Our results suggest that the morphological data are in agreement with the molecular phylogenetic tree in which the taxonomic status of L. khorassanicum is confirmed as a new species. Based on IUCN Red List categories and criteria, L. khorassanicum and L. turcomanicum are evaluated as Endangered and Near Threatened species, respectively.

Abstract Coomansus batxatensis sp. nov., recorded from Vietnam, is described and illustrated and its phylogenetic relationship within the Mononchida is analysed. The molecular data (18S and 28S ribosomal DNA) are provided for the new species. The new species is characterized by small body size (body length, L = 0.7–0.9 mm); buccal cavity sub-rectangular in shape, flattened at base, 21–24 × 12–13 μm or 1.9 (1.7–2.0) times as long as wide; posterior position of dorsal tooth apex (59–63% from the base of buccal cavity); pars refringens vaginae with faint and small (2.5 × 1.7 μm) teardrop-shaped pieces, short pars distalis vaginae; and males with short spicules (50–51.5 μm) with rounded head and conical blade part. The new species is close to Coomansus parvus but differs from it by the smaller buccal cavity size, more posterior position of the dorsal tooth apex, longer tail and presence of males. An updated identification key to Coomansus species and a compendium of all the species known are presented.

Lines Of Evidence

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.
