Rhotana suttoni Zelazny, sp. nov. (Fig. 252) Description. Forewings 1.8 times longer than wide, length about 4.7 mm. Colour stramineous; apex of clypeus and parts of the legs light orange-brown. Forewings glassy, lightly infuscated in apical third and along most veins. Veins orange-red but claval and basal sections of cubital veins stramineous. Hindwings lightly infuscated with most veins orange. Facial carinae contiguous up to lower margin of eyes; subantennal processes well -, lateral carinae of pronotum poorly developed. Forewings with apical section of Sc strongly sinuate; a small triangle at base of Ms1; Ms1 branched at basal third, Ms1b connected to middle part of Cu1 by a short crossvein. Pygofer of male genitalia with a pair of prominent, pointed lateral projections. Genital styles with a short proximal and an elongated distal dorsal process, a small hump between both. Aedeagus short with two needle-like terminal processes. Etymology. The species is named for the collector and ' suttoni ' is a latinized noun used in the genitive case. Type material. Holotype ♂ (forewing 4.7 mm), BRUNEI; labels: 1) Brunei, Labi / Bukit Teraja / 30km S.E. of Seria / 21–28.iii.1979 2) Primary mixed/dipterocarp/forest, alt. 60m. 3) light trap 2/ 50m. above ground/ L. Sutton / B.M. 1985-50 (BMNH). Distribution. Borneo (Brunei). Diagnosis. Rhotana suttoni resembles closely R. venosa Distant which also occurs in Borneo. Externally it can be separated from most specimens of R. venosa by its mesonotum, rostrum, legs and forewing veins lacking the brown coloration and by the forewings having more orange-red veins. However, a few specimens of R. venosa approach R. suttoni in coloration. Males of both species can be readily distinguished by the structure of the aedeagus.
