Genus Orthophana Melichar, 1923

Orthophana MELICHAR, 1923: 11 . Type species: Orthophana spinata Melichar, 1923 (by original designation).

Identification key to the subgenera and species of Orthophana

1 Branches of radius of tegmina with a common stem basally and costal vein furcating apically; tegmina without apical tooth-shaped spine ( Fig. 3 A ). Ratio LTg/BTg = 1.93. Hind tibia with two lateral spine distally. Lateral margins of frons not projecting laterally before clypeus ( Fig. 3 C ). General coloration brown or dark brown ( Fig. 3 A-C). Larger, total length: 14-15 mm – N Vietnam......................................................(subgenus Eupharos ) O. tamdaoina Gnezdilov & Constant, 2014 - Branches of radius of tegmina separated since basal cell and costal vein simple; tegmina with apical tooth-shaped spine ( Figs 1 A , 5 ). Ratio LTg/BTg = 2.2. Hind tibia with one lateral spine distally. Lateral margins of frons projecting laterally before clypeus ( Fig.1 C ). General coloration green or brown ( Figs 1 A-C, 5). Smaller, total length <12. 5 mm. Malaysia and Vietnam................. .....................................................................................................................(subgenus Orthophana ) 2 2 General coloration green; hind wings white; costal margin of tegmina smoothly rounded ( Fig. 5 ). Total length: 12.5 mm – Malaysia............................................................. O. spinata Melichar, 1923 - General coloration brown with dark brown markings; hind wings yellow and largely infuscate; costal margin of tegmina sinuate on posterior half ( Fig. 1 A-C). Total length: 11.9 mm – Central Vietnam........................................................................................................... O. bidoupensis sp. nov.

Note: the coloration as a character proposed to separate the subgenera Eupharos (brown) and Orthophana (green) by GNEZDILOV & CONSTANT (2014) is not valid. The series of characters allowing the separation of the two subgenera is consequently restricted to the tegmen shape and venation, the structure of the head and the spines on the hind tibiae as mentioned in the above key.
