Description
Worker
Holotype. TL 1.8, HL 0.46, HW 0.37, CI 80, ML 0.14, MI 30, SL 0.28, SI 76, PW 0.27, AL 0.48. Answering to the description of Strumigenys erynnes but differing as follows.
1 Propodeum armed with a pair of triangular teeth, each subtended by a narrow lamella down the declivity.
2 First gastral tergite with about a dozen suberect short remiform hairs, arranged in rows over the whole sclerite (rather than being restricted to an apical pair and a basal pair).
3 Averaging smaller than erynnes and with somewhat shorter scapes (compare measurements).
Paratypes. TL 1.8-2.0, HL 0.44-0.52, HW 0.37- 0.41, CI 79-84, ML 0.13-0.15, MI 26-30, SL 0.28-0.32, SI 76-80, PW 0.26-0.60, AL 0.47-0.54 (4 measured).
Type Material
Holotype worker, Madagascar: Prov. Fianarantsoa, 28 km. SSW Ambositra, Ankazomivady, 1670 m., 11.i.1998, 20 °46.5'S, 47°10.1'E, #1620(31)-1, sifted litter, grassland (B.L. Fisher) (The Natural History Museum).
Paratypes. 1 worker with same data as holotype; 1 worker, 1 queen and 1 male with same data but #1620(37)-7; 2 workers and 2 queens with same data but #1620(17)-9 (BMNH, Museum of Comparative Zoology, in coll. Fisher (where there are also some specimens in alcohol)).
