Abstract

In the present study, a new species of the genus Teloganopsis Ulmer, 1939, T. sirindhornae sp. nov., is described based on specimens collected and reared in Thailand. The new species is distinguished from other Thai Teloganopsis species by its abdominal color pattern, which is consistent across all developmental stages. Both morphology characteristics and molecular analysis support its designation as a new species. A concatenated phylogenetic tree based on COI and 28S rDNA confirms its monophyly and clearly separates it from other Teloganopsis species. Additionally, a description of the chorionic structure of T. sirindhornae sp. nov., a distribution map of known Teloganopsis species in Thailand and a dichotomous key for both larval and imaginal stages of known Oriental Teloganopsis species are provided.
