Tambinia macula Wang & Liang 2011

Body length (from apex of vertex to tip of forewings): ♂ 5.6 mm (N=1). Colour. General colour ocherous, vertex (Figs 1B, 3A) with median carina suffused reddish, the reddish extending from the sides, forming two reddish long stripes, its outer margins irregular, pronotum (Figs 1B, 3A) with a pair of reddish spots at disc depression between median and lateral carinae, frons (Fig. 3C) suffused with pale reddish, forewings (Figs 1B, 3D) with basal portion ocherous, with two red elongate marks near bases of sutural margins, many orange or red spots marked from basal part to nodal line, nodal line suffused with one transverse orange to red band, tips of spines on hind tibiae and tarsi black. Head and thorax. Head (Figs 1B, 3A) projecting before eyes approximately median length of eye, strongly dorsoventrally depressed. Vertex (Figs 1B, 3A) about as long as broad, two times as long as median length of pronotum, anterior margin projected at an obtuse angle in dorsal view, lateral margins ridged and converged anteriorly; median carina thin and percurrent; posterior margin straight. Frons (Fig. 3C) longer in middle than the widest breadth (1.3: 1), disc slightly depressed, covered with sparsely microsetae (Figs 3B, 3C); 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; without median carina. Clypeus (Fig. 3C) triangular, without median carina. Pronotum (Figs 1B, 3A) distinctly shorter than mesonotum in midline (0.3: 1), carinae strongly ridged, lateral carinae diverging posteriorly, median carina distinct, reaching posterior margin. Pronotum and mesonotum together medially 2.1 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 1B, 3D) relatively broad, with basal portion semihyaline, thicker than apical portion, without granulation, 2.7 times as long as maximum breadth, Sc+R forking about medially, Cu1 forking after level of junction of claval veins, cell Sc with a short cross vein at its apical angle, with 12 apical cells and 5 subapical cells, claval veins uniting distad of middle of clavus. Male genitalia. Pygofer (Figs 3E, 3G, 3H) narrow and high, wider ventrally than dorsally, anterior margin concave medially, posterior margin produced caudad in lateral view. Anal tube (Figs 3E, 3F) relatively elongate, ventral margin nearly straight and directed caudad in lateral view; lateral margins slightly diverging distad, apical margin concave in dorsal view; anal styles relatively long, distinctly surpassing apex of anal tube in dorsal view. Gonostylus (Figs 3E, 3G, 3H) elongate, basal half broad and apical half abruptly narrow in lateroventral view; median conical process very thin and slender, sclerotized in ventral view. Periandrium (Fig. 3E) tube-like, distinctly sclerotized, with a short process directed ventrad at dorsal apex, surrounding aedeagus medially. Aedeagus (Fig. 3E) with shaft very long and thin, simple tubule, sinuate and its apex directed caudad in lateral view, endosoma indistinct.
