Type material.

Holotype ♂ (pinned), Myanmar, Chin, Chin Hills, Natma Taung National Park, 8 miles camp, area of Mt. Victoria, 2500 m a.s.l., 6-8.x.2002, at light, genitalia in glycerine vial (MfN).

Paratypes (pinned): 2 ♂, same data as holotype (MfN)

Etymology.

The species is named in honour of Janos Oláh, who reviewed the Oriental and Afrotropical species of this genus.

Diagnosis.

The new species belongs to the C. holzschuhi group ( Oláh et al. 2008a), which is defined by the presence of apicodorsal lobes on segment IX and apicoventral setal lobes on segment X. The male genitalia of the new species resemble C. automedon Malicky & Chantaramongkol, 1997 (Thailand) and C. meyi Malicky, 1997 (Vietnam). Each of these species, however, has specifically-formed harpagones, allowing their clear separation and identification.

Description.

Length of forewing 5-5.5 mm. Head and thorax black, cephalic warts with black bristles, eyes small, interocular index 1.0, antennae dark brown, longer than forewing length, indistinct spots at articulations on ventral side; legs brown, inner spur of fore-tibiae very small; forewings brown, with golden-brown macula on subapical costal field, fork 1 present, hindwings sparsely covered by brown hairs, fork 1 present.

Male genitalia (Fig. 7D-F ). Ventral part of segment IX broad, dorsal part short and narrow; apicodorsal lobes of segment IX widely separated in dorsal view and with pointed tips in lateral view, apicoventral lobes on segment X short and rounded; inferior appendages shorter than phallotheca, harpagones deeply split into a longer median branch and a shorter, lateral branch; phallic apparatus with phallotheca bulbous at base and narrowed subapically, endothecal processes evenly rounded, oval, phallotremal sclerites large, clearly separating endothecal processes at their bases.

Distribution.

Myanmar, Chin Hills.

Biology.

Mountainous species with flight period in autumn. Adults are attracted by light.
