Obrimus quadratipes is a stick insect species from the family of Heteropterygidae native to the Philippine island of Luzon.

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.

Since the genus is so far only known from Luzon, more recent works assume that Obrimus quadratipes is also endemic there.

[1] Ignacio Bolívar described the species in 1890 as Obrimus quadratipes on a juvenile male that had meanwhile been deposited as a lectotype in the Museo Nacional de Ciencias Naturales in Madrid.

[5] Frank H. Hennemann transferred the species back to the genus Obrimus in 2023 due to the slit-shaped depressions in the metasternum, since its transfer to the genus Brasidas by Rehn and Rehn was based on incorrectly identified material.
