Descriptions. Specimen (GU/ R /B/G/3009) ( Fig. 2 View FIGURE 2 ). Incomplete tegmen with postero-apical part missing; original coloration not preserved; wing 24.8 mm long, about 8.2 mm wide; ScP ends on anterior margin, 8.8 mm from wing base, with weak anterior branches; R ends at wing apex, with numerous distally forked anterior branches, all parallel; area between R and anterior wing margin 2.6 mm wide; RA and RP not well differentiated; median area rather reduced, with few branches of M; CuA with numerous parallel branches covering a broad area; CuP+PCu strongly arched and concave; veins of postcubital-anal area all parallel and ending into CuP+PCu.

Specimen (GU/ R /B/G/3004) ( Fig. 3 View FIGURE 3 ). Distal halves of a tegmen and a hind wing, darkened (original color); fragment of tegmen 16 mm long, about 5.5 mm wide ( Fig. 3A View FIGURE 3 ); numerous anterior branches of R and area between R and anterior wing margin broad, ca. 2.3 mm wide ( Fig. 3A View FIGURE 3 ); fragment of hind wing 6.7 mm long with numerous branches of main veins ( Fig. 3B View FIGURE 3 ) and a part of anal fan ( Fig. 3C View FIGURE 3 ), partly folded below rest of wing so that cubital branches seem not to be parallel to anal fan.
