A similar excavation is visible in the distomesal face of the cercus
02 mm wide (n=3), striate except near basis, setulose basally; cercus
setose and secondarily lobed; hypoproct narrow, conspicuously longer than cercus
, deeply bilobed, and setose; aedeagus and hypoproct subequal in length, aedeagus 0.
Male: sternite IV with similar width and height; sternite V "V-shaped"; cercus
and surstylus with almost the same length of the aedeagus.
Surstylus with upper blade of bifurcated tip swollen and lower one shorter; cercus
with ventral appendix, which is directed posterior (Figs.
3-5): dark brown; tergite 9 not produced beyond apex of gonocoxite, lateral margins of proximal 1/2 straight, slightly divergent, lateral margins of distal 1/2 convergent, posterior margin rounded; sternite 9 with conspicuous, elongate, narrow posteromedian projection extending to gonocoxite midlength; sternite 10 slightly visible, spiculate, produced beyond base of cerci; cercus
6): tergite 9 short, not extending to apex of gonocoxite, posterior margin rounded; cercus
short, extending beyond margin of tergite 9; sternite 9 broad, with shallow posteromedial excavation, proximal 1/2 yellowish, distal 1/2 dark brown.
To measure cerci, I removed the right cercus
from each frozen male's abdomen, placed it in a labeled tube, and returned the animal to the freezer for later molecular analysis.
thick at base, narrowing towards and gradually transforming into apical third; moderately curved with spinule at tip Fig.
separate, large and broad, as long as broad.
occidentalis Sturtevant, 1954): epandrium and surstyli connected with internal structures of terminalia; cercus
moderately well sclerotised, longer than wide, porrect posteriorly, not narrowed apically, bearing several moderately long setae, but lacking stout, tooth-like setae at apex; surstyli fused with ventral margin of epandrium, asymmetrical or symmetrical, narrow and rounded apically, bearing sparse, short setulae on apical half; a well-sclerotised process joining base of surstylus; gonite distinct and comparatively long, tapered ventrally, shorter than surstylus.
simple longer than supra-anal plate, Subgenital plate subacute.
Male terminalia (Figure 8): Gonocoxite not splayed with mesobasal lobe; gonostylus elongate and striate, paramere slender, aedeagus truncate at the apex and longer than hypoproct, hypoproct with parallel lobes and cercus
with divergent lobes.
