Material ( NHMUK). Holotype, male, Amboasary [25°3′S / 46°23′E], R. Mandrare, [Anosy Region], S. Mad. [agascar], ( R. Catala , 1934) // NHMUK individual number 012832487 // slide NHMUK: 010315518.

Description. Male. Antenna bipectinate, setae three times longer than antenna rod diameter. Length of fore wing 13 mm. Fore wing light-creamy with poorly expressed sputtering of brown scales (more expressed in anal area), thin dark-brown bands postdiscally and submarginally, poorly noticeable reticulated pattern of wavy brown lines in marginal and submarginal area. Hind wing light-creamy without pattern. Fringe on all wings light-creamy.

Male genitalia. Uncus basally narrow, with parallel margins from base to middle of length, gradually narrowing distally, apically acute; tegumen robust; gnathos arms of medium thickness, long; gnathos robust, covered with fine spikes; valve with robust crest on costal margin (on border between medium and distal third), sclerotized rib on inner surface of valve (about 1/2 of valve in width), apex of valve poorly sclerotized, semicircular; transtilla process hook-like, long, apically acute; juxta compact with long thick lateral processes; saccus semicircular, compact; phallus poorly curved, very thick, with two small prongs on ventral surface in distal third, equal to valve in length, with obliquely cut, acute apex, vesica aperture in dorso-apical position, about 1/2 of phallus in length, vesica without cornuti.

Female unknown.

Diagnosis. The new species differs from the other species of the genus in the very light coloring, very thick phallus with two small prongs on the ventral surface in distal third.

Distribution. Southern Madagascar, Anosy Region.

Etymology. The new species is named after the type specimen collector, Dr. René Catala, a famous French entomologist and hydrobiologist who worked for a long time in Madagascar, and later participated in the creation of the French Institute of Oceania in New Caledonia in 1946 ( Hladik 2014; Meunier 2016).
