Habitus, male and female genitalia (Figs 5, 46–48). Distinct by virtue of orange cast to basal and postmedial areas of forewing. Male genitalia distinct by virtue of wide, rounded uncus without modifications; heavy, long recurved setal tufts at costa of valva; and intrasaccular patch of heavy setae. Female genitalia distinct by virtue of elongate, robust bursa combined with conspicuous appendices bursae.
Male (Fig. 5). Forewing length: 7.0–11.0 mm (n=14). Head (Fig. 14) - Ocelli present; proboscis normal; frons conical or expressed as a small hump; labial palpi porrect, extending beyond clypeus. Thorax - Legs white, forelegs cupreous dorsally, as basal tarsomeres on all legs. Female with two pair of hind tibial spurs (medial pair present). Forewing. Basal, antemedial, and subterminal fasciae brownish orange, shaded distally with white (dark basad). Both antemedial and postmedial lines shaded distally with white (dark basad); antemedial and postmedial areas rust colored/cupreous; medial area sparsely suffused with white. FW fringe brown. Hindwing. postmedial line faint if present; HW yellowed at margin, subterminal line interrupted; fringe whitish beige. Abdomen - Cupreous sheen; white abdominal bands on all segments. Scales arranged in two terminal black dorsal spots in males. Tympanal organs (Fig. 25). As for ysticalis-themis group, vide supra. Male genitalia (Figs 46, 47) - Teguminal sulcus short, such that anterior margin of tegumen appears deeply invaginate, the two oblong teguminal lobes joined obliquely. Uncus wider than long; terminal edge of uncus entire. Gnathos quadrate. Juxta an inverted triangular plate or robust “V”, less sclerotized at center. Valvae complex; costa robust with recurved, elongate tufts of setae; subcostal lobe with petiolate scales, most arched towards dorsal articulation of valva; with secondary outer, oblong lobe or process below costa; with fleshy setose lobe associated with terminus of costa and located between distal portion of costa and lower portion. Intrasaccular process a simple flange, the inner surface of which bears chisel-shaped setae; with robust, spine-like setae at base; submarginal area of sacculus setose. Saccular margin angled close to vinculum, not at saccular mid-point; ventro-marginal setae concentrated at saccular ulna. Phallus moderately sclerotized; vesica with a small cornutus. Female genitalia (Fig. 48) - Papillae anales separate, more or less round, flat, and swollen; ostium bursae with membrane between seventh and eighth segment; antrum membranous; colliculum present as a sclerotized collar of intermediate length embedded within ductus bursae; two conspicuous appendices bursae located at posterior end of corpus bursae; corpus elongate, membranous, without signa; ductus seminalis near posterior end of corpus bursae.
