Nothing is known about the biology of Strumigenys reticeps.

Identification

Bolton (2000) - A member of the Strumigenys thaxteri-group. Pilosity on the leading edge of the scape is damaged or not clearly visible in the holotype and single other specimen available. For this reason I have keyed the name twice, running out reticeps through each lug of the important couplet dealing with curvature of hairs on the scape. Discovery of further material will allow determination of its real track through the key.

Keys including this Species

Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Description

Worker

Bolton (2000) - TL 1.9, HL 0.48-0.52 (excluding clypeal tooth), HW 0.38, CI 73-79, ML 0.04, MI 7-8, SL 0.23-0.24, SI 61-63, PW 0.26-0.27, AL 0.52-0.56 (2 measured).

Easily isolated from all other Neotropical members of Pyramica as it is the only known species to have the following series of characters in combination, as well as the group characters listed above.

1 Midpoint of anterior clypeal margin extended into a sharp triangular tooth that projects forward over the mandibles.

2 Clypeus, and a broad triangular area of the cephalic dorsum immediately behind the clypeus, glassy smooth, contrasting strongly with the densely reticulate-rugulose remainder of the dorsum.

3 Dorsum of clypeus with numerous fine acute simple hairs that are all erect and shallowly curved posteriorly.

4 Head in full-face view with 3 pairs of flagellate hairs: first pair arising dorsally just behind the frontal lobes, directed anteriorly; second pair on upper scrobe margin just in front of level of eye, freely projecting laterally (omitted from Kempf' s (1969) figs. 7 and 8); third pair on side of occipital lobe, freely projecting laterally.

Promesonotum with a median carina; on each side of the carina pronotum with sparse feeble posteriorly divergent costulae on a smooth surface. Mesonotum with some punctulate sculpture and the propodeal dorsum reticulate-punctate. Petiole node punctate and feebly rugulose dorsally. Pronotal humeral hair long, fine and flagellate.

Type Material
