Description. Forewings 2.0 times longer than wide, length about 4.6 mm. Colour stramineous; mesonotum light brown; middle tibiae tinted with red (fore legs missing in examined specimen). Forewings with 6 dark marks near hind margin, distad of claval tip; a large grey area at middle of wing in front of these marks; two faint bands of infuscation across wing base, along anterior apical cross-veins, and along apical margin; veins stramineous, but reddish in between the dark marks. Hindwings colourless (damaged in the examined specimen). Facial carinae not quite meeting at their bases; rostrum surpassing post-trochanter; subantennal processes and lateral carinae of pronotum well developed. Forewings with apical part of Sc nearly straight; Sc+R fork well before middle of wing; Ms1 branched near tip of basal median cell, a large triangle at base of Ms1. Male genitalia with pygofer narrow. Apical part of aedeagus flat, tapering towards a nearly pointed end; a rounded, flat dorsal lobe covers the right side.

Etymology. The species name is a latinized noun (Argus, from the Greek mythology who had many eyes) used in apposition.

Type material. Holotype ♂ (forewing 4.6 mm), INDONESIA: SULAWESI; labels: 1) SULAWESI TEN- GAH:/ Nr. Morowali,/ Ranu River Area ./ 27.i. – 20.iv. 1980 2) M.J.D. Brendell / B.M. 1980-280 3) At / light ( BMNH).
