Trichopelma zebra

Trichopelma zebra was first described by Alexander Petrunkevitch in 1925, under the name of Merothele zebra, a new genus he erected for the species, and which he placed in the family Barychelidae.[1][2] In 1985, Robert Raven made Mesothele a junior synonym of Trichopelma, saying that "it does not differ in any character of generic significance".[3][4] In 2015, the genus was placed by José Guadanucci in a much reduced subfamily of the Theraphosidae, Ischnocolinae sensu stricto.[5]

T. zebra has dusky-brown femurs, spinnerets, chelicerae, and cephalothorax. All other leg segments are chestnut-brown. The abdomen is purplish-brown, with five grey stripes running backward and five median grey spots. It is 17 mm (including chelicerae).

The maxillae and labium are spinulose. It lacks a rastellum on the chelicerae. All tarsal scopulae are bisected longitudinally.
