Strumigenys deletrix

The type was found in a lowland rainforest litter sample.

Identification
Bolton (2000) - A member of the cordovensis complex in the Strumigenys mandibularis-group. Although very close to Strumigenys cordovensis the development of the two characters given above is considered sufficient to isolate deletrix as a separate species. In all material of cordovensis examined an apicoscrobal hair is present and the humeral hair is stiffly erect and very conspicuous.

Longino (Ants of Costa Rica) - Apical fork of mandible with a single intercalary tooth; mandible with two conspicuous preapical teeth; mandible extremely long, longer than head; gaster smooth and shiny; specialized humeral hair short, broadly spatulate, curved posteriorly and closely applied to the surface; dorsolateral margin of the head close to the apex of the scrobe without stiff projecting hair.

Worker
Holotype. TL 3.5, HL 0.76, HW 0.59, CI 78, ML 0.83, MI 109, SL 0.60, SI 102, PW 0.36, AL 0.74. Closely related to cordovensis and answering the description of that species, but differing as follows.

1 Pronotal humeral hair short and spatulate, scarcely longer than the pronotal ground pilosity, curved posteromedially and closely applied to the surface rather than erect.

2 Apicoscrobal hair absent.
