Genus Encaumaptera Hampson, 1893

Type genus (by original designation) Brachylia stigmata Hampson, 1891 .

Redescription. Adults of medium size, similar to the representatives of the сossid genera Roerichiora Yakovlev & Witt, 2009 (type species Zeuzera stigmatica Moore, 1879 ). Antenna bipectinate along all length, antenna processes about two times longer than antenna rod diameter in its medium third. Fore wingwith poorly expressed pattern, hind wing without pattern, noticeably shorter. Abdomen apically without modified scales collected in a brush.

Male genitalia.Uncus robust, tapered, apically rounded; tegumen large; gnathos arms thick, relatively long, large leaf-like processes at bases of gnathos arms (more dorsally) on tegumen; gnathos massive; valve narrow, slightly narrowing from base to apex, with small notchon border between medium and distal thirds of costal edge, with small triangle harpe; juxta small cup-like; saccus tiny; aedeagus robust, short, straight, with small paired linear-shaped cornuti along lateral surfaces of vesica.

Females unknown.

Diagnosis. The new genus is distinguished in the weak wing pattern, the absence of modified abdomen scales, large tapered uncus, big leaf-like processes at bases of gnathos arms, narrow valve with a small harpe, straight thick phallus with small paired linear-shaped cornuti along the lateral surface of the vesica.

Composition. The genus Encaumaptera includes three species so far: E. stigmata ( Hampson, 1891) , E. aurora sp. nov., and E. devyatkini sp. nov.

Distribution. Indochina ( Vietnam and Thailand), south-eastern or Southern India (Tamil Nadu), Sri Lanka ( Fig. 27 ); its range strongly disjunct and incompletely known.
