Brasidas quadratipes

Obrimus quadratipes is so far only known from two male specimens, namely the juvenile lectotype and an adult male in the collection of the National Museum of Natural History, France (MNHN) in Paris. In these specimens too, the slits in the slits in the metasternum (metasternal pseudoforamina) typical of the genus Obrimus are very narrow and barely recognizable. The juvenile lectotype is 42 millimetres (1.7 in) long, the adult male 64 millimetres (2.5 in) long. In contrast to all other males of the genus known to date, those of Obrimus quadratipes do not have any spines on the second to fourth tergum of the abdomen. There are eight spines on the head. A large pair of spines can be found on the posterior edge of the pronotum. On the anterior edge of the mesonotum is a smaller pair of spines, in its middle is a barely noticeable or missing pair, and on its posterior edge there is another pair of spines just as large as the one on the pronotum. The pair of spines on the posterior edge of the metanotum is just as large. The metapleurae are very spiny. In contrast to Obrimus mesoplatus, Obrimus quadratipes lacks both the prominent, central pair of spines on the mesonotum, as well as the spines on the anterior and the triangular lobes on the posterior abdominal segments.
