Fig. 04 (♂ —App), Fig. 18 (♂ —habitus), Fig. 40 (D— ♂ pectoral color pattern).

Etymology: falcifer = falx, Latin for scythe + ferre, Latin meaning bear, in reference to the scythe shape of the male cercus.

Diagnostic characters. ♂ — Cercus in lateral view: basal 1/4 straight, apical 3/4 almost rectangular with a semicircular notch in the middle of the bottom edge. Cercus in mediodorsal view: base of cercus without spine, medial expansion fused with the apical portion of cercus forming a roughly rectangular plate. Paraproct in lateral view: more than half the size of the cercus, with a tuff of pale hair–like setae directly upward. Paraproct in dorsal view: almost triangular with a spoon–like tip.

♀ —female undescribed, but as almost all females have pectoral color pattern much similar to that of males, the male pattern was added for comparative purposes ( Fig. 40D ).
