Morphological And Molecular Data

An investigation of the taxonomic status of Pareas hamptoni (Hampton's Slug snake) based on morphological and molecular data revealed a new distinct species from the Golden Triangle region (comprising parts of southern China, and adjacent Laos and Thailand). The new species is shown to be a sister species to P. hamptoni but can be separated from the latter by having 3–5 dorsal scale rows at midbody slightly keeled (vs 5–9 scales strongly keeled); a lower number of ventrals, 170–188 (vs 185–195); and a lower number of subcaudals, 67–91 (vs 91–99). The new species is currently known from northwestern Thailand, northern Laos, and the southern part of Yunnan Province in China at elevations of 1,160–2,280 m a.s.l. We suggest that the new species to be considered of Least Concern (LC) in the IUCN‘s Red List categories. Problems of taxonomy and actual distribution of the P. hamptoni complex are briefly discussed; our results show P. hamptoni is now reliably known only from Myanmar and Vietnam, but its occurrence in Yunnan Province of China is likely.

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.

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 of Cymbidium (Orchidaceae), Cymbidium xichouense, from Yunnan Province, China, is described and illustrated based on morphological evidence and molecular analyses. The new orchid is morphologically similar to C. qinbeiense, but it has several morphological features that distinguish it from C. qiubeinense and all other recognized species in Cymbidium. Phylogenetic analyses based on nuclear (ITS) and plastid DNA (matK) were conducted, and the results also supported the status of C. xichouense as a new species, which is sister to C. qiubeiense.

Colletotrichum sonchicola, sp. nov. from Sonchus sp. (dandelion tribe) in Forlì-Cesena Province, Italy, is introduced using morphological and molecular data. Combined phylogenetic analysis of ITS, GAPDH, CHS, ACT and TUB2 sequence data demonstrate that C. sonchicola is a distinct species within the dematium species complex. The new species is illustrated and compared with related taxa. This provides the first record of a Colletotrichum species from the genus Sonchus.

Water mite species of the genus Mideopsis Neuman, 1880 are common in running and standing waters in the Palaearctic. In the present study we used an integrative taxonomic approach by applying partial COI sequences (DNA-barcodes) and morphological characteristics to describe a new species, Mideopsis milankovici sp. nov. from the Mediterranean region of Montenegro. A high genetic distance (18.8-26% K2P) from three other known European congeners, M. crassipes Soar, 1904, M. orbicularis (Müller, 1776), and M. roztoczensis Biesiadka and Kowalik, 1979, support M. milankovici sp. nov. as a distinct species. From M. persicus Pešić and Saboori, 2015, a species known from South Iran, which resembles the new species in the shape of the ejaculatory complex, M. milankovici sp. nov. differs by the morphology of dorsal shield.

A new species of Cymbidium (Orchidaceae), C. weishanense, from Yunnan Province, China, is illustrated and described based on morphological and molecular evidence. Morphological comparison indicates that C. weishanense is similar to C. concinnum but differs in several floral characteristics. Molecular analyses based on nuclear ribosomal (ITS) and plastid DNA (matK and rbcL) support the status of C. weishanense as a new species. Due to the low support for nrITS, it is possible that this is a natural hybrid of C. concinnum with C. insigne or another related species.

A new species of Cymbidium (Orchidaceae), Cymbidium biflorens, from Yunnan Province, China, is illustrated and described based on morphological and molecular evidence. Morphological comparison indicates that C. biflorens is similar to C. rhizomatosum, but differs by its leafless, coralline rhizome, normally two flowering periods, a shorter scape, inflorescence with 1–2 flowers, greenish flowers with longer pedicel and ovary, subelliptic petal, petals and lip not fully opened. Molecular analyses base on nuclear (ITS) and plastid DNA (matK and rbcL) were conducted to explore the phylogenetic position of the species. The molecular evidence supports C. biflorens as sister to C. rhizomatosum.
