Abstract
A new species of microhylid frog of the genus Glyphoglossus Günther, 1869 is described from Huadianba, Cangshan Mountain, Dali Bai Autonomous Prefecture, Yunnan Province, China. Glyphoglossus huadianensis, new species, is compared with congeners from China and other parts of Southeast Asia, and was distinguished from the others by the following combination of characters: adult male body size up to 37.8 mm; pupil rounded; supratympanic fold distinct; tympanum concealed; toe tips obtuse; subarticular tubercles prominent and rounded; foot webbing extensive; outer metatarsal tubercle present; dorsum tuberculate, yellowish-brown/earth-yellow; and a pair of conspicuous large round spots in groin. The new species is the tenth species of Glyphoglossus to be described, and the second known from China.

Glyphoglossus huadianensis sp. n.
Diagnosis: The new species of Glyphoglossus is medium-sized
(average SVL 36.5 mm in adult males; body size of taxa of
Glyphoglossus ranges from 26.9 ± 3.3 mm to 61.3 ± 0.7 mm; Table
4), and shares the following combination of characters with its
congeners: flattened body; wide head; short snout; small eyes;
maxillary and vomerine teeth present; paired dermal folds
across palate; a crescentic, inner metatarsal tubercle present
(Inger, 1966; Manthey and Grossmann, 1997; Parker 1934).
The new species can be diagnosed from other congeners by
the combination of the following characters: adult male body
size larger than 34 mm (SVL range of 34.8–37.8 mm); pupil rounded; supratympanic fold distinct; tympanum concealed;
toe tips obtuse; subarticular tubercles prominent and rounded;
webbing between toes extensive, extending up to the second
subarticular tubercle on toe IV; outer metatarsal tubercle
present; dorsum tuberculate; and a pair of conspicuous large
round spots in groin.
Etymology: The name huadianensis refers to Huadianba, the locality where the new species was first found. Its Chinese common name is “huā diàn xiǎo xiá kǒu wā” ( 花甸小狭口蛙 ).
