Strumigenys dromica

Nothing is known about the biology of .

Identification
Bolton (2000) - A member of the cygarix complex in the Strumigenys caniophanes-group. Four species in the group lack preapical dentition on the mandible, Strumigenys caniophanes, Strumigenys heteropha, Strumigenys cygarix and Strumigenys dromica. Of these caniophanes has dense sulcate sculpture on the lateral alitrunk, cygarix has conspicuous appressed pubescence on the first gastral tergite between the bases of the flagellate main pilosity, and heteropha has the katepisternum unsculptured; dromica contradicts all of these. Apart from these features caniophanes and heteropha have the petiole subclaviform in profile whilst cygarix and dromica have a well differentiated long anterior face to the node.

Worker
Holotype. TL 2.6, HL 0.68, HW 0.50, CI 74, ML 0.33, MI 49, SL 0.42, SI 84, PW 0.32, AL 0.70. Mandible in full-face view without preapical dentition. Dorsolateral margin of head in full-face view with 4 freely laterally projecting fine flagellate hairs: one in front of level of eye, one at level of eye, one in apicoscrobal position and one closer to the occipital corner. Cephalic dorsum with standing hairs present from just behind level of eye to occipital margin, the posteromedian pair, that straddles the midline, long and flagellate. Dorsal surfaces of head, alitrunk and waist segments densely sculptured. Side of alitrunk densely punctate to punctate-shagreenate everywhere. Pronotal humeral hair very long and flagellate, more than 0.50 X SL. Dorsal alitrunk with fine simple standing hairs, the dorsolateral margins also with very long flagellate hairs. Waist segments and first gastral tergite with shorter fine standing hairs and very long flagellate hairs. Dorsal and ventral surfaces of femora with standing fine hairs; dorsal (outer) surfaces of middle and hind tibiae and basitarsi with sparse very long erect flagellate hairs. Petiole in dorsal view broader than long. Node of petiole in profile with an almost vertically ascending anterior face. Basigastral costulae shorter than length of postpetiole disc.
