Palaeontinidae Handlirsch, 1906 View in CoL

Gansucossus Wang, Zhang et Fang, nom. nov. pro Yumenia Hong, 1982: 81 , nec Yumenia Hou, 1958: 93 .

Type species. Yumenia pectinata Hong, 1982 ; by present designation.

Revised diagnosis. Hind wing length 22–32 mm, length/width ratio 1.5–1.9; costal area wide (length/width ratio 3.6–5.5); Sc terminating in indentation; RP fused with M1 for a considerable interval; Stem M with four branches; M3+4 connected to CuA by crossvein m­cua; media area (between M2+3+4 and CuA) wide; CuA arising basally; A1 terminating in anal margin.

Similar to Shurabocossus, but differs in the hind wing being comparatively long, stem M long, and A1 terminating in the anal margin. This genus differs from Plachutella in having M3+4 arising from M2+3+4 and A1 terminating in the anal margin; from Fletcheriana in having RP fused with M1, and M3+4 arising from M2+3+4; from Suljuktaja in having the hind wing relatively long, stem M long, and A1 terminating in the anal margin; and from Cicadomorpha in having a different shape of costal area (maximal width in basal 1/4–1/3 for Cicadomorpha ).

Type locality and horizon. Lower­Middle Jurassic, Dashankou Group; Subei County, Yumen City, Gansu Province, China.

Etymology. The generic name is after the type locality, Gansu Province.

Composition. Three species, Gansucossus pectinatus ( Hong, 1982) , Gansucossus luanpingensis ( Hong, 1983) , and Gansucossus typicus sp. nov., described below.
