Description

Worker

HL 0.77-0.92 (0.88); HW 0.60-0.72 (0.70); SL 0.80-0.97 (0.90); PW 0.40-0.50 (0.50); WL 1.03-1.23 (1.17).

Head. Conspicuously longer than broad, CI 77-84 (79); in frontal view, widest at eye level, usually distinctly sinuate below eye level; occipital margin evenly convex. Scape about as long as head, SI 119-133 (129); extending beyond occiput by about 0.3 x its length. Eye large, OMD 0.86-1.17 (1.17) x EL. Apical margin of clypeus, in frontal view, slightly convex, weakly emarginate in middle.

Thorax. Slender, PW 0.38-0.43 (0.43) x WL. Mesonotum, in profile, straight or slightly convex, not angulate beyond middle. Propodeum, in profile, not depressed in front of tubercle; tubercle high, acute.

Vestiture. Head with sparse, appressed, whitish pubescence; thorax and gaster with appressed pubescence longer and a little denser; some cephalic pubescence, especially on frons may be decumbent; that of scape decumbent to erect.

Cephalic setae sparse, on face limited to clypeus and frontal lobes, none on occiput or vertex. Basalmost setae of psammophore below level of occipital foramen. Pronotum usually with a single pair of erect setae, which are shorter than apical width of scape; mesonotum and propodeum without erect setae. First gastric tergum with irregularly spaced, long, erect setae across summit of basal face and a row along posterior margin; remaining terga with sparse longer hairs. Scape without erect setae. Fore femur with three or four widely spaced setae along basal half of ventral margin; mid and hind femora without erect setae on dorsal margin; tibiae without setae.

Integument. Clypeus moderately shiny, closely shagreened except along midline; frontal lobes and frons moderately shiny, lightly shagreened and with scattered micropunctures; vertex and occiput sharply duller, closely shagreened and with numerous micropunctures. Thorax similar to occiput, closely shagreened and with numerous micropunctures. Gaster moderately shiny, less closely shagreened than thorax, with numerous micropunctures and scattered coarser punctures.

Color. Dark brown to blackish; antenna and legs lighter.

Type Material

Holotype and 41 paratype workers: Chile, Prov. Antofagasta: 2 km E Paposo, 300m elev., 16 Nov. 1972 (J. H. Hunt, #994). Holotype and most para types in Los Angeles County Museum of Natural History; three para types each in Museo de Historia Natural de Santiago and Museo de Zoologia.

Etymology

This species is dedicated to James H. Hunt, who collected numerous ant samples in Chile at my request.
