Nothing is known about the biology of Strumigenys quattuor.
Identification
Bolton (2000) - A member of the Strumigenys eurycera-group. Closely related to Strumigenys pharosa but that species has much less pilosity. In particular pharosa lacks projecting hairs on dorsolateral margin of head, lacks hairs at pronotal humeri and has no standing hairs at all on the dorsal alitrunk.

Description
Worker
Holotype. TL 2.1, HL 0.55, HW 0.45, CI 82, ML 0.24, MI 44, SL 0.29, SI 64, PW 0.26, AL 0.59. Inner margin of mandible with a narrow cuticular lamella that arises just proximal of the preapical tooth and extends almost to the base; at broadest the lamella is less than one-quarter the length of the preapical tooth. Apical antennal segment strongly constricted basally, narrowly articulated to preapical segment; the latter short and barrel-shaped, also strongly constricted basally. Leading edge of scape shallowly convex, broadest distal of the midlength, the leading edge with a series of elevated simple hairs that are curved toward the scape apex; longest of these hairs subequal to maximum width of scape. Eye minute. Scrobe absent. Side of head behind eye shallowly convex from top to bottom, without sharply defined dorsolateral or ventrolateral margins. Cephalic dorsum reticulate-punctate, without reticulate-rugulose sculpture posteriorly. Principal basigastral costulae much longer than maximum length of postpetiole disc. Dorsolateral margin of head with a short stiff laterally projecting hair behind level of eye; cephalic dorsum with short stiff stubbly erect hairs present from level of eye to occipital margin. Pronotal humeral hair present, stiffly erect and simple; pronotal dorsum with a single erect pair of hairs, between the humeral pair. Mesonotum with a single pair of similar erect hairs. Hairs on first gastral tergite short and stiff, truncated apically.
