Obrimus mesoplatus is a stick insect species from the family of the Heteropterygidae native to the Philippine island of Luzon.[2][1]
Obrimus mesoplatus is so far only known from a single specimen, namely the male holotype. In this case too, the slits in the metasternum (metasternal pseudoforamina) typical of the genus Obrimus are very narrow and barely recognizable. The male is a good 5.3 centimetres (2.1 in) long. This makes Obrimus mesoplatus the smallest species of the genus. The male has three pairs of spines on its head. There is a larger pair of spines on the pronotum. One pair of spines on the frontal edge and one in the middle of the mesonotum are hardly smaller. The front and rear edges of the metanotum also have a similarly large pair of spines. There are small pairs of spines on the second to fourth tergum of the abdomen. Triangular elevations (lobes) are located in the middle of the sixth to ninth abdominal tergum. Obrimus quadratipes lacks both the middle pair of spines on the mesonotum and the spines on the front and the triangular lobes on the rear abdominal segments.[2][1][3][4]
