Remarks. We examined all additional specimens of this species from Ratchaburi and Chiang Rai Provinces. We found they matched with the morphological characters of holotype and paratype. By the coloration of antennae, shape and coloration of tegmina, coloration of all legs, mesosternal and metasternal lobes, shape of epiproct and presence of the lateral shorted spine of paraproct of male, the male genitalia complex ( Figs. 1A–Q ), shape of female subgenital plate and ovipositor, as well as presence of two rows of thin hairs on female 7 th abdominal sternite only.
