Tisamenus fratercula is a stick insect species native to the Philippine island Luzon.

A male collected by W. Boetcher in Butucan in today's Batangas Province was deposited as holotype in the Academy of Natural Sciences of Drexel University.

[4] Males of Tisamenus fratercula are chocolate brown and reach a length of 35 to 45 millimetres (1.4 to 1.8 in).

In contrast to Tisamenus deplanatus, the triangular area on the mesonotum typical for the genus is significantly longer and forms an isosceles triangle.

Another difference to this species are the posteriores formed as paired spines on the second to fourth tergite of the abdomen in Tisamenus fratercula.
