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

Taxonomy

Batangas Province was deposited as holotype in the Academy of Natural Sciences of Drexel University. Females were not known until 2014. Rehn and Rehn placed the species in the Deplanata group they established within the genus. According to their description, this unites with Hoploclonia fratercula, Hoploclonia deplanata (today Tisamenus deplanatus), Hoploclonia cervicornis (today Tisamenus cervicornis), Hoploclonia armadillo (today Tisamenus armadillo), Hoploclonia spadix (today Tisamenus spadix) and Hoploclonia tagalog (today Tisamenus tagalog), relatively unspined species, with a flat upper surface, which except for the supra coxal spines on the edges of the thorax show no spines, but at most teeth.[2] In 2004 the Filipino species were transferred back to the genus Tisamenus and only those occurring on Borneo were left in the genus Hoploclonia, the species is referred to as Tisamenus fratercula.[1][3]

After specimens from the

conspecific. Frank H. Hennemann identified these specimens as Tisamenus fratercula, following the description by Rehn and Rehn. A 2021 study based on genetic analysis, which included representatives of both stocks or species, confirmed separate species status. It was also shown that the species are not as closely related to one another as suspected in the 1939 grouping.[4]

Description

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

tubercles. In the case of Tisamenus tagalog, all posterior parts of the abdomen are only formed as tubercles. The body structures of the wider females are similar to those of the males. They are lighter and more contrasty in color than the males and grow up to 55 millimetres (2.2 in) long.[2][5]

In terraristics

A stock to be found in the lovers'

bramble as well as other Rosaceae are eaten.[4][5][6]
