n. gen.
is the only genus that displays both front coxal process and unarmed prosternum. This genus is also characterised by the combination of the following characters: mid trochanteral spine usually present; mid dorsal apical spur present; mid dorsal subbasal spur present; Pro lateral lobes relatively deep; male epiproct not specialised; male cerci cylindrical, without processes; male paraprocts reduced, without processes; male epiphallus with cephalic lobe bifurcated; female tergite VIII with hindward projecting folds on lateral lobes.
DESCRIPTION
Body size moderate (
12-17 mm
). Pro: anterior margin strait or weakly concave; lateral lobes relatively deep; ventral margin rimmed; prosulcus distinct, mesosulcus distinct on lateral lobes. Prosternum unarmed; mesosternal processes forming inconspicuous bulge; metasternum unarmed. Thoracic opening of small size. FW and HW reduced but at least as long as Pro. Fore leg with distinct minute coxal spine.Tympanal area of T1 moderately inflated.Mid leg with a distinct trochanter spine (lacking in
one specimen
of one species).T2 with one dorsal subbasal spur; with dorsal apical spur.Ventral spur formulae: T1 7/7 (rarely 8) subapical spurs; F1 5/4 (rarely 5) spurs; T2 6/5-6 (proximal spur often minute) subapical spurs; F2 3 (rarely 2)/1-2 spurs. F3 with 5-9 ventral spines. T3 with: 11-14/7-11 ventral spines; 18-20/18-19 dorsal spines.
Males
Left mirror area D-shaped,higher than wide (
Fig.12
). Terminalia (
Fig. 11A, B
, F-G). Epiproct small, semicircular, not fused with last tergum, with a median longitudinal depression. Paraprocts very small,visible dorsally, apical end more or less pointing. Cerci: widened at basis; regularly curved inwards. SGP: broad; posterior margin sinuate, with a very shallow emargination; with small distinct styli. Genitalia (
Fig. 11
D-E, I-J). Phallus with bilobate sclerified plates on dorsal phallomeres. Epiphallus with single undivided rod, cephalic lobe divided apically; head without distinct tubercles (side view).
Females
SGP hind margin weakly or distinctly projecting (
Fig. 13
A-D).Tergite VIII with hindward projecting folds on lateral lobes. O weakly and gradually curved upwards with serrated margins apically.
