Figs. 5–9 , 20B

Additional description notes, both sexes. Tegmina surpassing the apex of abdomen, reaching basal third of hind tibiae ( Figs. 6 A–B , 8A–B ). Tegminal veins described based on one male and 4 females ( Figs. 6 C–D , 8 C–D , 9 ). Tegmina: radius with RS branching between middle and apical third of tegmen, both forked near tip; media anterior free from base but leaning on radius; cubitus anterior at base single branched, after divides into two branches about end of basal third of tegmen, the anterior branch makes a curvature and receives a short connection branch from MA, shortly after it divides into MP and CuA1 ( Figs. 8C–D , 9A, C–F ), or runs as fused MP+CuA1 till tip ( Figs. 6C–D , 9B ), the posterior branch does not divide further; cubitus posterior undivided, free throughout; with 3 or 4 anal veins, the last two with common base.

Discussion. The male subgenital plate of Furcilarnaca chirurga ( Fig. 5F, K ) is close to that illustrated in Fig. 1 by Bey-Bienko (1962). Based on the structure of the female subgenital plate which bears a deep and wide median concavity and the lateral lobes narrowly sharp on posterior margin, Furcilarnaca hirta is treated as valid species instead of being synonym of Furcilarnaca chirurga (Bey-Bienko, 1962) . This is in contrast with Furcilarnaca chirurga , where the posterior margin of the female subgenital plate has triangular median concavity and the lateral lobes rounded.
