Habitat/Ecology. This species is associated mostly with primary and secondary forests in Singapore, including young abandoned park and plantation secondary forests. Individuals were often collected from rotting logs and leaf litter. Nests were found under loose bark of fallen trees or logs.

Remarks. Often mistaken for and assumed to be E. heliscata (especially since E. heliscata was first described from Singapore), E. procera is morphologically distinct, e.g. body sculpture overall less coarse, body hairs sparse, generally finer and not explicitly clavate. Specimens in Singapore confer more with the form of E. procera malua ( Mann, 1919) than the primary types of E. procera , although the subspecies is now considered a junior synonym of the latter (thus invalid). We observed distinct differences in structure between original E. procera and the currently invalid subspecies malua that may warrant future raising of the latter to a separate species. For this checklist, however, in the absence of more compelling empirical evidence, we tentatively accept the conspecificity of E. procera and the subspecies malua.
