Echinopla pallipes

Specimens have been collected in dipterocarp forest and lower montane mixed dipterocarp forest.

Identification
Zettel and Laciny (2015) - A member of the Echinopla melanarctos group. Echinopla pallipes is similar to Echinopla melanarctos, but smaller (TL ca. 6 mm), and has pale legs, lower tubercles on head and mesosoma and strongly reduced tubercles on gaster tergite 1 (only anteriorly present). It differs from Echinopla tritschleri and Echinopla cherapunjiensis by the posterior position of the eyes, and from Echinopla circulus by the sculpture of the gaster tergite 1. Echinopla pallipes also differs from E. circulus in two other ways: it has parallel frontal lobes, they are slightly converging anteriorly in E. circulus and in head width, E. pallipes (HW 1.85–2.02) is smaller than E. circulus (HW 2.04–2.29) [it should be noted the HW range of E. pallipes includes data from an aberrantly large worker thus the HW of a typical worker is unlikely to be near the given upper range (2.02).
