MATERIAL EXAMINED. Holotype – male, Malaysia: Sabah Province, Crocker Range

Park, 02.III 2018, leg. M. Omelko; ( ZIN; gen. pr. No 1921).

DESCRIPTION. Male ( Fig. 1 ). Wingspan 17 mm. Head with bundles of tousled brown hairs. Labial palpi thin, 1,5 times longer than longitudinal eye diameter. Antennae thin,

brown. Thorax and tegulae white. Fore wings light-grey, interspersed with tiny brown scales.

Costal edge darkened, distally and apically with distinct elongated spots. Big dark triangle spot located below the apical one. Distinct dark elongated spots along dorsal edge are situated distally and medially. Wing noticeably lightened basally. Hind wings unicolorous, ash-grey.

Fringe on all wings grey. Contrast mottled pattern on legs: bright white portions alternating with black ones.

Male genitalia ( Fig. 2 ). Valves symmetric, apically rounded. Finger-shaped costal process basally. Uncus slightly widened in medium part, basally thinner, apically sharp. Saccus with round notch. Aedeagus short, almost straight, without cornuti.

Female unknown.

COMPARISION. In the colour and shape of the wings, the new species is similar to

Ochyrotica toxopeusi Gielis 1988 , but differs from latter by the clearly expressed dark elongated spots along the dorsal edge of the fore wing. In the general shape of male genitalia,

the new species has some similarity with O. yanoi Arenberger, 1988 , but differs from latter by the short, almost straight aedeagus and absence of the vinculum, while in O. yanoi aedeagus is long, arched and has an expressed vinculum.

NOTES. This species has been recorded from Sabah Province of Malaysia as Ochyrotica

sp. (Ustjuzhanin et al., 2018).

ETYMOLOGY. The species is named after the well-known Russian lepidopterologist,

Mikhail Omelko, who collected the new species of plume moth.
