A New Species

Isotrema cangshanense X.X.Zhu, H.L.Zheng & J.S.Ma, a new species from western Yunnan, China, is described and illustrated here. It is similar to I. utriforme, I. forrestianum, I. cucurbitoides and I. obliquum The major differences between them are outlined and discussed. A detailed description, along with line drawings, photographs, habitat and distribution, as well as a comparison to morphologically similar species, is also provided. Meanwhile, the new taxon is assessed as Vulnerable (VU D2), according to the IUCN Red List criteria.

A New Species

Begonia leipingensis D. K. Tian, L. H. Yang & C. Li (2n = 30), a new species in Begonia sect. Coelocentrum from the limestone area of Guangxi, China. B. leipingensisis is easily distinguished from any other compound-leaved species in Begonia by its large variation in petiolule number and its unique spirally-arranged petiolule pattern, which has never been seen in Begoniaceae before and rarely seen even in other angiosperm taxa. Besides having non-overlapping flowering periods, it is clearly different from B. fangii, the most morphologically similar species in the same section and with the same chromosome number. In addition to its unique petiolule pattern, B. leipingensis has longer abaxial wings, shorter internodes, and usually larger leaves, leaflets and habit. Molecular phylogenetic analysis showed that B. leipingensis formed an independent lineage belonging to Sect. Coelocentrum. Morphological and phylogenetic evidence strongly supports this species as a new taxon in Sect. Coelocentrum of Begonia. B. leipingensis was assessed to be critically endangered based on criterion outlined by IUCN Red List Categories and Criteria.

A New Species

Begonia fenshuilingensis X.X.Feng, R.K.Li & Z.X.Liu, a new species in Begonia sect. Platycentrum (Klotzsch) A.DC. (Begoniaceae) from southeastern Yunnan, China, is here described and illustrated. It morphologically resembles B. dryadis and B. daweishanensis, but differs by its fleshy trigonous-ellipsoid capsules without wings. Molecular phylogenetic analysis of ITS sequence data supports the new species as monophyletic, and distinct from the two similar species. Due to its limited distribution, we consider the new taxon as “Vulnerable D2” (VU D2) according to the IUCN Red List Categories and Criteria.

Primulina silaniae X.X.Bai & F.Wen, a new species of Primulina Hance (Gesneriaceae) from the limestone area of Wangmo County, Guizhou Province, is described and illustrated. The new species is similar to P. spiradiclioides Z.B.Xin & F.Wen, but can be easily distinguished from the latter by a combination of characteristics, especially in the lateral veins of its leaf and floral shape and tube. At present, three populations in one locality of this new taxon were found, totaling about 600 mature individuals. According to the IUCN Red List Categories and Criteria (Version 3.1), the species is provisionally assessed as Vulnerable [VU D1].

A New Species

A new species of indotyphlid caecilian amphibian, Hypogeophis montanus sp. nov., is described based on a series of specimens from the Seychelles island of Mahé, collected from two localities in 2013 and 2015. The new species most closely resembles the Seychelles (Mahé) endemic H. brevis in being short (maximum known total length in life ca. 110 mm) and long snouted, but differs by having more vertebrae, a relatively smaller head, and substantially distinct mitochondrial and nuclear gene sequences. Hypogeophis montanus sp. nov. is known from higher elevations (718–731 m) than H. brevis (ca. 350–650 m), and its elevationally restricted distribution on a single small island likely renders it threatened under IUCN Red List criteria. Hypogeophis montanus sp. nov. is the third species of small and long-snouted caecilian reported from the Seychelles. Along with H. brevis and H. pti, H. montanus sp. nov. is among the smallest known species of caecilian and possibly has the smallest global distribution.

Begonia tinuyopensis is described and illustrated as a new species from Zamboanga del Norte, Philippines. This new species resembles B. mearnsii by having a decumbent stem, scattered hairs over the entire plant, terminal inflorescence bearing 2 staminate tepals and 5 pistillate tepals. However, Begonia tinuyopensis is distinct by having sparse pilose (vs. matted with long brown hairs) stems, ovate (vs. suborbicular to subreniform) leaves and glabrous (vs. densely pubescent) ovary. We assign B. tinuyopensis as Endangered (EN) following IUCN Red List Criteria.

We describe a new species of Ptychadena from Mutinondo Wilderness in northern Zambia. It has rupicolous tadpoles that develop in a film of water. The species is distinguished on morphology, advertisement call and DNA sequences from other grass frogs and was found to be most closely related to P. broadleyi. It has no contrasting longitudinal bands on the posterior thigh, the foot is longer than half SVL, it has no light triangle on the snout, three phalanges of the fourth toe free of web and the snout has no skin folds. The species should be considered Near Threatened in terms of the IUCN Red List criteria given its limited extent of occurrence and population size.
