Description of Antaeola rhinosa sp. nov. (Lepidoptera: Tortricidae: Olethreutinae) from Thailand.

The genus Antaeola has remained monotypic since its description by Diakonoff in 1973. A new species, Antaeola rhinosa sp. nov., is described and illustrated from Thailand. The new species can be distinguished from A. antaea (Meyrick) by facies and features of the male and female genitalia.

The first checklist of the tribe Olethreutini (Lepidoptera: Tortricidae: Olethreutinae) of Thailand.

Olethreutini fauna in Thailand consists of 171 species belonging to 57 genera. This checklist is based on literature in which Olethreutini species have been described or recorded and identified specimens that were deposited in Kasetsart Kamphaengsaen Insect Collection (KKIC), Thailand. Of those, 36 species still were reported only in Thailand. Five genera (Lipsotelus, Meiligma, Metrioglypha, Prophaecasia, and Psilacantha) are new records for Thailand. Furthermore, 29 species are also recorded from Thailand for the first time.

A fifth species represented only by a single female is morphologically characterized but not formally described. Sirindhornia is most closely related to Anthozela Meyrick and Irianassa Meyrick but is easily distinguished by unique appendages of the tegumen and a conspicuous henion in the male genitalia.
