Dichomeris matsumurai Ponomarenko & Ueda, 2004: 151 . TL: Thailand.

Material examined. CAMBODIA: 3♂, Kep (10°29'N, 104°18'E), 17.vii.2012, leg. Y. S. Bae et al., genitalia slide No. CIS-6685 ; 3♂, 1♀, same locality (10°30'N, 104°18'E), 11.xi.2015, leg. Y. S. Bae et al., CIS-6697 ; 1♀, Pursat (Osami), 2.v.2010, leg. Bae, Chae & Vi ( INU) .

Diagnosis. Adult ( Fig. 12 ) wingspan 20.0–21.5 mm. This species is similar to D. bulawskii Ponomarenko & Park, 1996 superficially. It is easily differentiated from D. bulawskii by the vinculum without lateral lobes and the aedeagus with two sclerotized lobes from the zone in the male genitalia ( Fig. 25 ), and the eighth tergite straight on the posterior margin in the female genitalia ( Fig. 34 ). In D. bulawskii , the vinculum has two asymmetrical lateral lobes, the aedeagus bears four sclerotized lobes from the zone, and the female eighth tergite has sclerotized quadrate plate on the posterior margin ( Ponomarenko & Park 1996: 114, Figs 1, 5–8 ).

Distribution. Cambodia (Kep), Thailand.
