Key to the Dictyopharidae known from Nepal

1 Mesonotum with lateral carinae nearly straight and parallel ( Figs 1A, B ; 2A ); lobes of phallobase on aedeagus with long sclerotized spines around ( Figs 3D–F ) ( Dictyopharini ). .............................................................. 2

– Mesonotum with lateral carinae incurved and convergent ( Figs 1D, E ); lobes of phallobase on aedeagus without long sclerotized spines ( Orthopagini ). .......... 3

2 Cephalic process in front of eyes narrowed and distinctly slender; vertex with basal width narrower than transverse diameter of eyes ( Figs 1A , 2A–C ). ................ .............. Dictyohimalaya nepalensis gen. & sp. nov.

– Cephalic process in front of eyes not narrowed and distinctly robust; vertex with basal width equal to or wider than transverse diameter of eyes ( Fig. 1B ). ......... .................................................................... Raivuna sp.

3 Apex of cephalic process truncated; forewings with a large sublunate fuscous streak on posterior margin of apical area; fore femora flattened and dilated ( Fig. 1D ), with a large blunt spine near apex. .................................. .............................. Orthopagus lunulifer Uhler, 1897
