Forewings 2.1 times longer than wide, length
4.5–4.7 mm
. Colour stramineous; margins of facial carinae and hind margin of pronotum orange. Forewings unpowdered; a red band along apical cross-veins between Cu, Cu1 and Ms1a; adjacent to the band, three elongated dark marks and two irregular grey marks; narrow, faintly infuscated bands across 1st, 2nd, and 4th subcostal sectors, across apex of basal median cell, and along Ms3, a middle section of M, the apical part of Ms2, and the apical margin; rest of forewings yellowish brown with some hyaline areas; veins stramineous, red near and inside red band. Hindwings colourless. Carinae of vertex and frons separated; rostrum reaching posttrochanter; subantennal processes and lateral carinae of pronotum well developed. Forewings with apical part of Sc nearly straight; Sc+R fork just before middle of wing; Ms1 branches near apex of basal median cell, base of Ms1a connected to M by a cross-vein, apical section of Ms1b touching Cu1. Male genitalia with pygofer narrow. Genital styles broad; truncate at the end; proximal dorsal process short and broad; distal dorsal process elongated.

Diagnosis.
Rhotana deminuta
shows similarities to
R. lalage
Fennah
, also found in
New Caledonia
. It can be distinguished by the red stripe on the forewings accompanied by three oval marks, by the Ms1 fork being closer to the Ms1 base, by the crossvein between M and the Ms1a base, by the end of the genital styles being truncated, and by the apex of the aedeagus being curved to the left.
