Diagnosis. Body entirely orange-testaceous, black claws contrasting well with much lighter tarsal segments (Figs 1–3). Scales on elytra fine, hair-like, not longer than width of elytral interval (Fig. 9). Rostrum markedly distinctly sexually dimorphic in length, in male 1.07–1.21 as long as pronotum (Fig. 1) and 2.84–3.20 as long as its maximum width, in female 1.45–1.61 × as long as pronotum and 4.38–4.81 × as long as wide (Fig. 8). The distance between antennal pit and rostrum base longer than (in female 1.14–1.23 ×) or subequal (in male 0.91–1.04 ×) to eye length; in female scape longer than maximum rostrum width (1.07–1.22) and 3 rd funicular segment 1.2–1.3 × as long as wide. Pronotum in male 1.65–1.70 ×, in female 1.60–1.65 × as wide as head. Elytra 1.59–1.76 × as wide as pronotum, in male at mid-length 1.21–1.28 × as wide as at base, in female 1.56–1.63 × as long as wide. In male profemur as thick or slightly thicker than rostrum width (1.00–1.06), protibia straight, 5.44–5.90 × as long as wide; in female protibia 1.04–1.11 × as long as pronotum.
Male. Spiculum gastrale with apodeme no longer than fork (Fig. 24). Tegminal plate with evenly sclerotized ventral layer; sclerotisation of parameroid lobes narrowly extended to apical lobes along inner margins; fenestrae not transparent, with unclear margins (Figs 19, 20). Aedeagal apodemes 0.65 × as long as pedon; tectum narrowed apically; pedon about 3.8 × as long as wide; endophallus densely microspinose (Figs 26, 27).
Female. Tergite 8 subtruncate, with several long setae along apical margin. Ovipositor as in Fig. 16, coxites weakly divergent; styli with several apical setae shorter than stylar length. Bursa unilobed. Spermatheca as in Fig. 17, with thin duct and shapeless gland.
