A New Species

The Graphium (Pazala) mandarinus group was recently defined and the status of taxa as well as the number of species was revised. We report here the discovery of a new species from Kon Tum plateau of the Truong Son (Annamite) Range of Central Vietnam, which we describe based on morphological and molecular evidence. Molecular phylogeny shows that the new taxon, G. (P.) wenlingae Hu, Cotton & Monastyrskii sp. nov., is sister to G. (P.) daiyuanae Hu, Zhang & Cotton, 2018 plus G. (P.) confucius Hu, Duan & Cotton, 2018. Molecular dating analysis further suggests that this new species diverged from its sister clade in the Pliocene (~3.5 million years ago). The new taxon constitutes the eighth and southernmost species of the mandarinus group.

A New Species

We describe a new species of salamander of Bolitoglossa (Oaxakia) Parra-Olea, García-París and Wake, 2004 from the cloud forests of the central portion of the Sierra Madre del Sur highlands in the Mexican state of Guerrero. Bolitoglossa coaxtlahuacana sp. nov. is currently known only from the type locality and can be differentiated from other members of the group by morphological, coloration, and molecular evidence. With the description of this new taxon, the number of species in the subgenus Oaxakia increases to six.

A New Species

A new species of Maytenus has been discovered in the Brazilian Atlantic Forest. The new taxon, Maytenus nemorosa, occurs mostly in ombrophilous rain forests at an elevation of 500 m to 1200 m. Maytenus nemorosa resembles M. gonoclada but differs from it by possessing oblong-elliptical leaves with entire margins and larger fruits with thicker pericarp walls. A phylogenetic analysis was conducted with nrITS and plastid matK regions, including the new species and additional taxa available from the NCBI-GenBank. The results from the phylogenetic analysis places Maytenus nemorosa nested within a clade of species that have fruits possessing a coriaceous pericarp and close to both Maytenus gonoclada and Maytenus salicifolia, as expected from morphological similarities. Additionally, M. cardenasii and M. erythrocarpa, from Bolivia, are both recognized as new synonyms for M. floribunda after an examination of their descriptions, types, and diverse collections.

A New Species

Based on molecular phylogenetic analyses and morphological characters, a new species from Bangladesh, northern Vietnam, and southwestern China, Leptolejeunea nigra, is described. It is mostly similar to L. balansae but remarkable for having brownish black ocelli in its leaf lobes. In the molecular phylogeny, the samples of L. nigra are not nested within any clade and form an independent lineage. In particular, the molecular dating suggested that the divergence of L. nigra happened in time span of the formation of the Himalayas.

Paris variabilis, a new species from the Wumengshan Mountains, southwestern China, is described and illustrated. The new species is placed in Paris section Euthyra. The new taxon was determined to be most morphologically similar to P. vietnamensis but differs in its oblong leaf blades with an acute apex, stamens 2–4 × petal number, greenish yellow filaments and an enlarged, purplish red style base. The phylogenetic placement of this species was assessed based on nuclear ribosomal ITS DNA sequences data. The results of morphological and phylogenetic analyses support the status of the taxon as a new species.

A New Species

A new species of Amphiesma is described from the Truong Son (Annamite mountain range) of Quang Binh Province in central Vietnam. This new species is characterized by the combination of the distinct coloration and pattern, the slender body and tail (tail/total length ratio 0.31), the large eye diameter, a single loreal and preocular, three postoculars, a single anterior and posterior temporal, nine supralabials (fourth to sixth reach the eye), nine infralabials, 179 ventrals (plus two preventrals), anal plate divided, 99 divided subcaudals, dorsal scales in 19-19-17 keeled rows, 34 maxillary teeth (the two posteriormost enlarged), hemipenis simple, with undivided sperm groove, covered with small spines except for a single, strongly enlarged spine next to the sperm groove at the hemipenis base and except for irregularly arranged medium-sized spines that encircle the organ horizontally at the trunco-pedicel area. The new taxon is known only from a single male specimen that was collected in a limestone forest valley.

Based on morphology and molecular phylogeny, it is described as a new species, H. wujiangensis sp. nov. A detailed description and illustration are provided, along with molecular evidence for the new species.

A New Species

We describe a new species of treefrog of the genus Ptychohyla from southern Mexico occurring to the east of the Isthmus of Tehuantepec. This new species can be distinguished from Mexican congeners by a combination of a pale pink iris and the presence of nuptial excrescences in breeding males. Including this new taxon, the number of species of Ptychohyla increases to 14, with seven of these occurring in Mexico. The new species is relatively common in pristine tropical forests, but appears to be sensitive to habitat degradation and has not been found in human modified habitats, suggesting that habitat modification is a threat for this hylid frog.

A New Species

Cuba has the highest diversity of snakes in the genus Tropidophis, representing 53 % of all the known species. Tropidophis steinleini sp. nov. is described from the eastern region of Cuba, raising the number of species to 17 in this archipelago. The new species is most closely related to T. wrighti, T. spiritus and T. morenoi. We discuss the phylogenetic relationships of this new species and other species of the genus in Cuba, based on molecular data, and classified them within three species groups according to the obtained tree topology.
