Diagnosis

The male pedipalp is slightly similar to that in Phintella brevis sp. nov., but differs in the presence of a hook-shaped process at the apex of the bulb and a small triangular lobe on the retrolateral side of the bulb posteriorly (both absent in P. brevis ). The shape of the tibial apophysis is also different, sharp in Phintella transversa sp. nov., and with an extra tooth in P. brevis .

Etymology

The specific epithet refers to abdominal pattern of this species.
