Tambinia conus Wang & Liang 2011

Body length (from apex of vertex to tip of forewings): ♂ 6.5 mm (N=1). Colour. General colour tawny yellow, vertex (Figs 1A, 2A) with two short reddish stripes, pronotum (Figs 1A, 2A) with a pair of orange spots outside lateral carinae, median carinae on vertex and pronotum orange, mesonotum (Figs 1A, 2A) with a pair of orange spots beside lateral carinae near posterior margin, genae (Fig. 2B) with orange patch between eye and lateral margin of frons, forewings (Figs 1A, 2D) with many reddish spots marked from basal part to nodal line, tips of spines on hind tibiae and tarsi black. Head and thorax. Head (Figs 1A, 2A, 2B) projecting before eyes approximately median length of eye, strongly dorsoventrally depressed. Vertex (Figs 1A, 2A) slightly longer in middle than the widest breadth (1.1: 1), distinctly longer than pronotum at midline (1.6: 1); anterior margin projected at an obtuse angle in dorsal view, lateral margins ridged and converged anteriorly; median carina thin and percurrent, with a pair of short sublateral carinae basally between median carina and lateral margins; posterior margin straight. Frons (Fig. 2C) longer in middle than the widest breadth (1.4: 1), disc flat and smooth, covered with sparsely microsetae (Fig. 2B); lateral margins sinuous, diverging from apex, slightly concave at level of eyes, then diverging further to reach their widest point before converging to the clypeus; median carina slender, gradually thinning and obsolete posteriorly, almost reaching to frontoclypeal suture. Clypeus (Fig. 2C) triangular, with broad median carina. Pronotum (Figs 1A, 2A) distinctly shorter than mesonotum in midline (0.4: 1), carinae strongly ridged, lateral carinae diverging posteriorly, median carina distinct, reaching posterior margin. Pronotum and mesonotum together medially 2.2 times as long as median length of vertex. Hind tibiae each with 2 distinct lateral spines; spinal formula of hind leg 5–5–2. Forewings (Figs 1A, 2D) relatively elongate and narrow, 2.7 times as long as maximum breadth, with corium smooth, not granulate, Sc+R forking at 2/5 apical, Cu1 forking after level of junction of claval veins, cell Sc with a short cross vein at its apical angle, with 13 apical cells and 6 subapical cells, claval veins uniting basad of middle of clavus. Male genitalia. Pygofer (Figs 2F–H) narrow and relatively high, wider ventrally than dorsally, anterior margin moderately concave, posterior margin nearly straight on ventral half in lateral view. Anal tube (Figs 2F, 2G) distinctly elongate, surpassing to apex of gonostylus, ventral margin slightly bent ventrad in lateral view; lateral margins narrowing distad, apical margin distinctly forked in dorsal view; anal styles relatively short and stout, not surpassing apex of anal tube in dorsal view. Gonostylus (Figs 2F, 2H) very narrow, apical part dorsoposteriorly directed in lateral view; median conical process distinctly elongate and strong, sclerotized, nearly reaching to middle part of gonostylus in ventral view. Periandrium (Fig. 2F) distinctly short, ring-shape, with a long process directed caudad at ventral side, surround aedeagusat medially. Aedeagus (Fig. 2F) with shaft sinuate and apical half dorsoposteriorly directed in lateral view, apical part forking at endosoma, forming two process, which dorsal one distinctly longer than the ventral one; endosoma membranous, slightly expanded.
