Tisamenus ranarius is a stick insect species (Phasmatodea), in the family of the Heteropterygidae native to the Philippines.

The meso- and metathorax form a trapezoid that widens backwards, to which the abdomen attaches approximately the width of the anterior edge of the mesonotum.

A distinct longitudinal crest runs from the anterior edge of the mesonotum over the metanotum to the end of the abdomen.

[2][3] John Obadiah Westwood described the species in 1859 under the basionym Acanthoderus ranarius using a female, which he also depicts.

[1] Only Oliver Zompro transferred the species back to Tisamenus together with all other Philippine representatives except Ilocano hebardi.
