Strumigenys anchiplex

Nothing is known about the biology of .

Identification
Bolton (2000) - A member of the prosopis complex in the Strumigenys lyroessa-group. The bases of the mandibles in anchiplex are less strongly expanded laterally than elsewhere in the complex. In this species the ratio of ML to the maximum width across the outer margins is about 1.00; in the remainder the ratio is 0.80-0.90. Like Strumigenys propinqua this species has relatively long scapes, possesses a freely projecting pronotal humeral hair and does not have pilosity restricted to basal and apical pairs on the first tergite; unlike propinqua, anchiplex lacks standing hairs on the entire promesonotal dorsum.

Worker
Holotype. TL 2.1, HL 0.58, HW 0.45, CI 78, ML 0.21, MI 36, SL 0.27, SI 60, PW 0.27, AL 0.57. Characters of prosopis-complex. With the mandibles fully closed ML is about equal to the maximum width across the outer margins. Dorsolateral margin of head with narrowly spoon-shaped curved hairs on upper scrobe margin to level of apex of scrobe; these hairs similar in shape and size to those on leading edge of scape. Posterior to this are shorter, narrower hairs that are more strongly appressed; there is no apicoscrobal hair. Cephalic dorsum with a single standing hair at apex of each occipital lobe, otherwise standing hairs absent. Pronotal humeral hair stiff and feebly remiform. Dorsum of promesonotum without erect hairs. Waist segments with 1-2 pairs of curved hairs. First gastral tergite with three transverse rows of stiff hairs: one close to base, one just behind midlength and one close to apex. Cephalic dorsum and entire dorsal alitrunk finely reticulate-punctate; dorsum of petiole node more superficially punctulate.

Paratypes. TL 2.0-2.1, HL 0.57-0.58, HW 0.44-0.45, CI 77-78, ML 0.20-0.21, MI 34-36, SL 0.27-0.28, SI 60-62, PW 0.26-0.27, AL 0.56-0.57 (5 measured).
