Description.

Body length (from apex of vertex to tip of forewings): ♂ 6.2 mm (N=1), ♀, 6.6-6.8 mm (N=2).

Colour. General colour tawny yellow, vertex (Figs 1E, 5A) with six red spots, genae (Fig. 5B) with orange patch between eye and lateral margin of frons, forewings (Figs 1E, 5D) with two pairs of red spots near bases of sutural margins and distad of level of union of claval veins, relatively, tips of spines on hind tibiae and tarsi black.

Head and thorax. Head (Figs 1E, 5A) projecting before eyes 1.2 times as long as median length of eye, strongly dorsoventrally depressed. Vertex (Figs 1E, 5A) distinctly longer in middle than the widest breadth (1.1: 1), distinctly longer than pronotum at midline (2.3: 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 nearly straight. Frons (Fig. 5C) longer in middle than the widest breadth (1.6: 1), disc flat and smooth, covered with very sparsely microsetae (Figs 5B, 5C); lateral margins sinuous, diverging from apex, slightly concave at level of eyes, then slightly diverging to reach their widest point before converging to the clypeus; median carina long and slender, nearly reaching to frontoclypeal suture. Clypeus (Fig. 5C) triangular, with distinct median carina. Pronotum (Figs 1E, 5A) distinctly shorter than mesonotum in midline (0.3: 1), carinae strongly ridged, lateral carinae moderately diverging posteriorly, median carina distinct, reaching posterior margin. Pronotum and mesonotum together medially 2.0 times as long as median length of vertex. Hind titiae each with 2 distinct lateral spines; spinal formula of hind leg 4 –5– 2. Forewings (Figs 1E, 5D) relatively elongate and narrow, 2.8 times as long as maximum breadth, with corium smooth, not granulate, Sc+R forking at 2/5 apical, Cu1 forking at level of junction of claval veins, with 12-13 apical cells and 5 subapical cells, claval veins uniting distad of middle of clavus.

Male genitalia. Pygofer (Figs 5 F–H) moderately broad, anterior margin concave on dorsal 1/3, posterior margin convex caudad in lateral view. Anal tube (Figs 5F, 5G) distinctly elongate, almost surpassing to apex of gonostylus, ventral margin slightly curve dorsad in lateral view; lateral margins concave medially then diverging from apex, apical margin distinctly concaved in dorsal view; anal styles long and strong, surpassing apex of anal tube in dorsal view. Gonostylus (Figs 5F, 5H) very narrow, expanded subapically then narrowing to apex, directed caudad in lateral view; median conical process distinct, relatively short. Periandrium (Figs 5F, 5G) distinctly elongate and sclerotized, tube-like, surrounding aedeagus medially, with a long, sinuate process at left side, dorsoposteriorly directed. Aedeagus (Figs 5F, 5G) with shaft tubular, apical part abruptly curved through approximately 30˚, directed to right; endosoma indistinct.

Material examined.

Holotype ♂, AUSTRALIA: Kuranda N. Q. Australia, 1904.VIII.10. Koebele, W. M. Giffard Collection (CAS). Paratypes. 2♀♀, the same data with Holotype (CAS).

Etymology.

This new species is named for the presence of six reddish markings on vertex (Figs 1E, 5A).

Distribution.

Australia (Kuranda).

Remarks.

This species is similar to Tambinia conus but can be distinguished from the latter in the vertex with six red spots, forewings with two pairs of red spots and by the male genitalia structure (Figs 5 F–H), especially the shape of anal tube, median conical process of gonostylus relatively small, periandrium relatively long, with a long, sinuate process at left side, dorsoposteriorly directed, and the shaft of aedeagus apical part abruptly curved through approximately 30˚, directed to right.
