Remarks. (1) In the original description (Černý & Pinratana 2009), a male and a female specimen with the same label data as in the holotype were cited as paratypes. However, the sex of one of them was erroneously determined by the authors and both specimens are in fact females. (2) The book by Černý & Pinratana (2009) is supplemented with a CD containing a PDF file of an updated version of the original book layout. In this file, an additional male specimen from Lampang Province was added to the type series of O. thomasi . However, only the specimens listed in the original hard copy of the book can be considered as secondary types and the aforementioned specimen is to be treated as a non-type additional specimen examined.

Diagnosis. The forewing length is 8.0–9.0 mm in males and 7.4–9.0 mm in females. Sexual dimorphism is limited: the male has a pale ochreous hindwing with a diffuse dark grey terminal fascia stretching from the apex to the anal angle, whereas the female hindwing is blackish with ochreous basal area and anal margin. The species is superficially similar to O. binghami, the detailed comparison between the two taxa is provided above in the diagnosis of the latter species.

Distribution. Northern Thailand (Chiang Mai, Lampang, and Nan Provinces).
