Owadaglaea dominiki Benedek & Saldaitis sp. nov.

( Figs. 6 , 21 )

Type material. Holotype: male ( Fig. 6 ), Myanmar, West Chun State, Junction Mt. Victoria, 2320 m, 1. ii. 2005, leg. Löffler, in the collection of HSV; (slide No.JB 1644m)

Diagnosis. Owadaglaea dominiki shows a close resemblance to O. triangulifera ( Figs. 7, 8 , 22 , 27 ), but it can be distinguished externally by the presence of the black postmedian fascia. The male genitalia of O. dominiki differs by the shape of the uncus, corona and harpe, the stronger, thicker ampulla, smaller clavus and the shorter digitus on the left cucullus. The structure of the aedeagus and vesica of the two species is similar, but O. dominiki has a wider, more rounded coecum, a stronger carinal process and differently shaped vesica with larger subbasal diverticulum.

Description. Wingspan 34 mm, length of forewing 15 mm. Proper description is hindered by the rather worn condition of the single holotype specimen. Head, front and thorax dirty grey; ground color of forewings ash-grey; ante-and postmedial fascia shaply marked with black; claviform stigma moderately large, triangular; median fascia a diffuse shadow of black scales; reniform and orbicular discreetly presented; hindwings darker smutty grey. Male genitalia ( Fig. 21 ): Uncus short, narrower at subapical part, distal segment fishtail shaped, hairs slender; tegumen low; juxta large, bell-shaped, with rather strong triangular extension on the ventral side; vinculum strong, fairly narrow, V-shaped; valve moderately elongate; cucullus rather straight with acute, pointed apex; corona presented by a few stronger hairs only at upper half with a small digitus on the left side; sacculus assymetrical, longer and more flat on the right side, extensions short, triangular; clavus conical, standing more close to the vinculum on the left; harpe strong, turned at middle with basal bar equally as long; ampulla narrow, straight, fused with a rather wide, arcuate basis to the harpe; aedeagus turned at last segment, the carinal process a heavily sclerotized ridge on a conical basis; vesica moderately broad with a single, large subbasal diverticulum. Only the male is known.

Bionomics and distribution. The single male holotype was collected at light at intermediate elevations of the primary forest zone. Early stages and the food plant are unknown.

Etymology. The species is dedicated to Mr. Pierdiluca Dominik by the holder of the holotype.
