Short description. The body is generally large at the prosome and narrows to the urosome. The arms of the seminal receptacle are curved posteriorly. Caudal rami are diverging and naked. The marginal extension at the P4 basipodite bears few spinules. The distal margin at the P4 intercoxal sclerite is protuberant bearing small spinules. The medial apical spine of P4 endopodite is almost 3 times longer than the lateral spine. All the morphological characteristics concur with the descriptions and illustrations of Mirabdullayev (2003) and Dela Paz et al. (2016a).

Ecological distribution. Thermocyclops taihokuensis is found mostly in lakes, small pool, fish ponds, and rice fields. This species can survive and tolerate eutrophic condition.
