Abstract
In this study, a new species Kibakoganea unnahachotei sp. nov. is described. Additionally, a new junior synonym of Kibakoganea akikoae Hirasawa, 1992 = Kibakoganea akikoae satoi Nagai, 2004 syn. nov. is proposed. Including the new species, genus Kibakoganea Nagai, 1984 currently comprises 18 species globally, and three species are recorded from Thailand. The habitus, some behavioral notes, and key to species of Kibakoganea from Thailand are given herein.

Kibakoganea unnahachotei Hongsuwong and Pathomwattananurak, sp. nov.
Differential diagnosis. Kibakoganea was arranged into three main species groups based on the structures of the aedeagus (Do 2013). K. unnahachotei is placed in the species group with parameres symmetric and apical part not separated. Among them, K. yoshitomii Nagai, 2004 from Northern Laos and K. costata Muramoto & Kobayashi, 2019 from India showed the most resemblance but could be distinguished with the characteristic listed in Table 1.

Etymology. The specific epithet “unnahachotei” is named after a Thai entomologist, Thornthan Unnahachote, who has consistently been a valuable collaborator and has provided assistance during our entomological surveys.
