Proapocyrtus luzonicus SCHULTZE 1934 View in CoL ( Figs 9-11 View Figs 9-11 )

Propocyrtus luzonicus SCHULTZE 1934: 320 View in CoL (description of male), pl. 1: fig. 13 (habitus of male).

M a t e r i a l e x a m i n e d: Holotype male (Museum Dresden) from Mount Irid, Rizal Province in Central Luzon ; for labels see Fig. 11. View Figs 9-11

D e s c r i p t i o n: Colour black, elytra except lateral margins and most of tibiae and femora chestnut brown, dorsum of body ( Fig. 9 View Figs 9-11 ) with a few scattered bluish green scales, sides of body with numerous scales distributed as in Fig. 10 View Figs 9-11 .

Size (in mm): Holotype male: Total length 13.4; head length 3.4; pronotum length 2.9, width 3.0; elytra length 8.5, width 5.6; scape length 2.3; hind femur length 5.0; head width at eyes 1.91; interoculus 0.96; rostrum length 1.74, width 1.19.

Structures: Dorsum of rostrum with moderately dense, fine puncturation and with distinct, narrow median furrow in posterior third, weakly extended until mid-length. Head between eyes with punctures of similar size, but more sparsely set. Dorsum of head behind eyes with very fine shagreen and with a few minute punctures. Imaginary longitudinal line on pronotal disk crossing approximately 15 tubercles. Elytra of very characteristic shape, dorsally slightly flattened and strongly narrowed at apical fourth; dorsum rather abruptly turning to sides which bear a distinct elongate impression near humeri; medial part with regular rows of rather small punctures and with smooth interspaces; lateral parts with irregular punctures and interspaces partly with low, transverse wrinkles; intervals apically not ridged; apical process laterally with rather long ventrad directed setae, in apical view each elytron with a minute tooth. In ventral view with long, unseg- mented sternal plate (sternite 1?) reaching base of elytral process, which is hollowed. Possibly terminal segments lacking, or turned dorsad. The unique representative of this species was not dissected.

C o mp a r a t i v e n o t e s: Proapocyrtus luzonicus differs strongly from P. insularis by colour, scale pattern, shape of elytra, and short median furrow on rostrum.
