(Figs. 48, 47, 206)

Redescription. Forewings 2.1 times longer than wide, length in male 4.8–5.2 mm (mean = 5.0, n= 3). Colour stramineous; in side view margins of vertex and facial carinae orange-red; last three abdominal sternites and sides of pygofer orange-red; fore tibiae light brown, tip of hind tibiae and tarsi dark brown. Forewings not powdered, a large dark brown mark around apex of Cu1; bands of faint infuscations across base of first costal cell and across first and second subcostal sectors; apex of Sc and adjoining veins red; apical margin and most of costal margin orange-red; second and third subcostal sectors and apices of R and M orange to orange red; remaining veins stramineous to light brown. Hindwings with a large brown-black mark around first median sector, connected to a smaller, lighter mark around second median sector; an additional small, separate dark mark at apex of claval vein. Facial carinae contiguous up to lower level of eyes; rostrum short, not reaching hind coxae; subantennal processes and lateral carinae of pronotum poorly developed. Forewings with costal margin slightly -, apical part of Sc strongly sinuate; Sc+R fork well before middle of wing; Ms1 branched before its middle; Ms1b connected to apical part of Cu1 by a cross-vein, a small triangle at base of Ms1. Male genitalia with pygofer bearing pointed, lateral projections; anal segment with a pair of short, lateral processes. Aedeagus thick; ending in two long, pointed (rarely blade-like), slightly sinuate processes; in dorsal view, the right one overlapping the left one (lectotype), or at least both processes meeting at the tip.

Etymology. The species name is a Latin adjective ( latipennis , -is, -e = with broad wings).

Type material. Lectotype ♂ (here designated) (forewing 4.9 mm, body 3.1 mm), BORNEO; labels: 1) type 2) delatipennis Walk. 3) SAR. 4) Wallace ( BMNH).

Note. Walker described this species from Sarawak, Borneo but did not indicate how many specimens he studied. The only syntype present in the British Museum is here designated as lectotype .

Other material examined. BRUNEI, Labi / Bukit Teraja / 30km S.E. of Seria / 21–28.iii.1979, primary mixed/ dipterocarp/forest, alt. 60m, light trap /50 and 75 m. above ground/ L. Sutton /B.M. 1985-50, 3 ♂ ( BMNH) .

Distribution. North Borneo.

Diagnosis. Rhotana latipennis resembles R. crassa sp. nov., R. hirashimai sp. nov. and R. sabaea sp. nov., all three also from Borneo, and R. inoptata Yang & Wu from Taiwan. It can be recognized by the dark tips of the hind tibiae, the prominent mark on the forewings near the apex of Cu1, and by the male aedeagus ending in two prominent processes.
