Key for Identification of Adults of Trechepaphiopsis Species of the Gaoligong Shan Region

1. Elytra without discal setae....................................... T. asetosa (Uéno) Elytra with a single discal seta, at or near mid-elytral length, next to stria 3............. 2

2. Size larger, BL = 3.5 to 3.7 mm; specimen from southeastern part of Gaoligong Shan region (Baoshan County) .......................................... T. unisetigera (Uéno) Size smaller, BL = 2.8 to 3.5 mm; specimen from more northerly part of the Gaoligon Shan region .................................................................... 3

3. Median lobe of male aedeagus ( Fig. 27b ) with a sinuous form, apical lamella very thin in lateral view, trilobed in apical view ( Fig. 27c ), endophallus formed as a long sleeve densely covered with long, fine spines; specimen from the southcentral part of the Gaoligong Shan region (Lushui County) ............................................ T. unisetosa (Deuve) Median lobe of male aedeagus ( Figs. 28b – 31b ) with a more simple form, apical lamella thick- er in lateral view, monolobate in apical view ( Fig. 28c ), endophallus with scaly areas but without long spines............................................................. 4

4. Median lobe of male aedeagus ( Fig. 28b ) with apical lamella progressively narrowed in lateral view, apex narrow, bluntly rounded and slightly recurved dorsally (Lushui County)............................................................... T. uniporosa sp. nov. Median lobe of male aedeagus ( Figs. 29b – 31b ) with apex thicker and more broadly rounded in lateral view.............................................................. 5

5. Size larger, BL = 3.3 to 3.5 mm; median lobe of male aedeagus ( Fig. 29b ) with shaft thicker subbasally, then moderately narrowed toward apex, apex broadly rounded, slightly lobate (Fugong County).......................................... T. unisetulosa sp. nov. Size smaller, BL = 2.7 to 3.1 mm; median lobe of male aedeagus ( Figs. 30b – 31b ) with shaft of more consistent thickness throughout its length, apex short and rounded, not dilated.... 6

6. Median lobe of male aedeagus ( Fig. 30b ) with scaly spoon-shaped area of endophallus only slightly narrowed toward apex (Gongshan County) .............. T. monochaeta sp. nov. Median lobe of male aedeagus ( Fig. 31b ) with scaly spoon-shaped area of endophallus markedly narrowed toward apex (Fugong County)................. T. unipilosa sp. nov.
