Abstract
A new species of the genus Coeliccia Kirby, 1890, C. sirindhornae sp. nov., is described based on specimens of both sexes collected from Kanchanaburi Province, Thailand. This species can be differentiated from its congeners by its unique combination of morphological characters, including the shape of antehumeral stripe, the structure and pattern of prothorax, and the shape of anal appendages in both sexes, and the markings on the terminal abdominal segments in female.
