Nothing is known about the biology of Strumigenys nimravida.


A member of the Strumigenys thuvida-group. Closely related to Strumigenys belial and Strumigenys ravidura but distinguished by the presence of a humeral hair and standing pilosity on the head, alitrunk and gaster in nimravida and their absence in the other two. S. nimravida is also closely related to the West African Strumigenys tukulta, but that species lacks standing hairs on the cephalic dorsum and lacks projecting hairs on the dorsolateral margins of the head.

Holotype. TL 1.9, HL 0.50, HW 0.35, CI 70, ML 0.11, MI 22, SL 0.21, SI 60, PW 0.23, AL 0.52. Dorsal and outer surfaces of mandibles, clypeus and entire cephalic dorsum densely clothed with flat appressed scale-like hairs, diameter of hairs greater than the distance separating them. Dorsolateral margin of head with 1-2 laterally projecting short, simple stiff hairs; at least one near occipital corner and may be another in apicoscrobal position. With head in profile a pair of short, stiff standing hairs present close to occipital margin. Pronotal humerus with a stiff simple hair. Promesonotum with very sparse, widely scattered ground-pilosity of a few narrowly spatulate hairs; scale-like hairs similar to those on head are absent from promesonotum, petiole node and disc of postpetiole. Mesonotum with 2 pairs of short simple standing hairs. First gastral tergite with erect short simple hairs and a few minute hairs that are appressed and very narrowly spatulate. Cephalic dorsum finely superficially reticulate-punctate and with some very weak rugulae, but the sculpture mostly obscured by the scale-like pilosity. Remainder of body unsculptured and smooth. Ventral spongiform lobe of postpetiole massive; in dorsal view projecting farther forward than the anterior margin of the disc.

Paratype. HL 0.50, HW 0.34, CI 68, ML 0.12, MI 24, SL 0.20, SI 59.
