Abstract:
Raorchestes is a group of Bush frogs mainly distributed in South and Southeast Asia that are poorly recognized by morphological criteria. We recognize the true R. menglaensis (Kou) based on 10 specimens newly collected from the type locality. An expanded description is also provided, and we delist the recently reported record, R. parvulus (Boulenger) from China. Combing with morphological and molecular data, two new species are respectively described from Menghai and Lvchun, Yunnan, China. Raorchestes hillisi sp. nov. is distinguished from all other congeners by the following combination of morphological characters: (1) small body sized (males 15.9–17.7 mm, n = 7; female 17.5 mm, n = 1); (2) head longer than wide; (3) snout longer than eye diameter; (4) the tip of upper jaws slightly notched; (5) internasal space slightly less than interorbital space; (6) tympanum distinct; (7) fingers lacking lateral dermal fringe; (8) outside of toe I and both sides of toe II lacking lateral dermal fringe, other toes having weak lateral dermal fringes; (9) rudimentary web on toes; (10) lacking a series of tubercles along the outer sides of forearm and foot; (11) discs of fingers and toes not orange. Raorchestes huanglianshan sp. nov. is distinguished from all other congeners by the following combination of morphological characters: (1) small body size (males 17.0–19.6 mm, n = 12; female 21.5 mm, n = 1); (2) head slightly wider than long or equal; (3) snout longer than eye diameter; (4) the tip of upper jaws slightly notched; (5) internasal space distinctly less than interorbital space (6) tympanum distinct; (7) fingers lacking lateral dermal fringe; (8) toes lacking lateral dermal fringe; (9) rudimentary web on toes; (10) lacking a series of tubercles along the outer sides of forearm and foot; (11) discs of all fingers and toes orange or parts of them orange in life.
