Short description. This species is relatively larger than the 2 Thermocyclops observed in this study. The body is generally large at the prosome and narrows to the urosome. The lateral arms of the seminal receptacle are long and broad and are curved posteriorly; the anterior margin has wave-like indentations at the proximal; Transverse duct-like structure forms a “ V ” shape. This species is highly recognized by the several hairs present at the entire median length of the caudal rami. The medial apical spine of the P4 endopodite is longer than the lateral, with spinules present at the entire anterior surface of 1 side and few spinules at the medial surface of the other side. All the morphological characters concur with the description of Hołyńska (2003) and Dela Paz et al. (2016a).

Ecological distribution. Mesocyclops aspericornis is found in wide variety of habitats including lakes, ponds, swamps, and rice fields (Lopez et al. 2017). This species has a great dispersal capability but adequate in competitive abilities.
