Description

BODY. Head capsule with vertex longer than wide, strongly projecting in front of eyes. Anterior margin triangular, lateral margins slightly diverging posteriorly, posterior margin anteriorly rounded concave; no median carina. Frons with lateral margins slightly diverging down to below level of the antenna, then converging to continue with lateral margin of postclypeus; median carina weak and thin, continuing on the clypeus; a pair of short dorsal latero-median carinae vanishing at the level of the compound eyes. No median ocellus. Rostrum long, with tip between metacoxae. Pronotum with anterior margin strongly produced, rounded, postocular carina interrupted behind compounds eyes, laterally continuing in an anteriorly curved ridge. Mesonotum with a weak median carina and a pair of lateral ones, anteriorly bifid. Tegulae large, bicarinate. Tegmina broad, extending far beyond the end of abdomen, with venation distinctly reticulate; costal area present and wide, with reticulate venation; ScP+R, MP and CuA branched separately on the basal cell.

LEGS. Hind tibia with 5–7 lateral spines. Metatarsus: basimetatarsomere with asymmetrical row of apical teeth, midmetatarsomere with symmetrical row of apical teeth. Metatibiotarsal formula: 8/12/2.

MALE TERMINALIA. Male gonostyli ( Figs 12 , 13B ) symmetrical, not fused medioventrally, more or less trapezoidal, with a small basal triangular expansion on its dorsal margin; capitulum not developed.

FEMALE TERMINALIA. Gonoplacs wide, flat, quadrangular, with no apical marginal teeth. Gonapophyses IX with a long lateral digitated process. Anal tube short, ring-shaped.
