Neotropical Region: Chile.

Nomenclature

 *  hypocritus. Araucomyrmex hypocritus Snelling, R.R. 1975: 12, figs. 16, 17 (w.) CHILE. Combination in Dorymyrmex: Shattuck, 1992c: 85.

Worker
HL 1.03-1.08 (1.08); HW 0.83-0.92 (0.92); SL 1.17-1.23 (1.23); PW 0.57-0.62 (0.60); WL 1.43-1.57 (1.57).

Head. Conspicuously longer than broad, CI 81-85 (85); in frontal view, widest at eye level, slightly sinuate below eye level; occipital margin nearly flat in frontal view. Scape distinctly longer than head, extending beyond occipital margin by about 0.45 x its length; SI 134-140 (135). Eye large, OMD 1.06-1.25 (1.25) x EL. Apical margin of clypeus, in frontal view, nearly straight, with barely indicated median sinuosity.

Thorax. Slender, PW 0.38-0.41 (0.38) x WL. Mesonotum, in profile, nearly straight, not angulate beyond middle. Propodeum, in profile, not depressed in front of tubercle; tubercle high, acute.

Vestiture. Appressed pubescence short, sparse on fronsg denser on occiput; longer and denser on thorax; long and dense on gastric terga, including sides of first two segments; very scattered around antennal sockets and on sides of head; completely appressed on scape.

Clypeus with long setae on apical margin and a few on basal margin, disc with a few very short setae; frontal lobes with a seta pair near clypeal base and another at level of lower eye margin, the latter notably long; vertex with a single pair of short setae (apparently broken off in some specimens). Basalmost setae of psammophore below level of occipital foramen. Pronotum with a median seta pair and a preapical, much shorter pair; mesonotum and propodeum without erect setae. First tergum with a few scattered setae on posterior half of dorsal face; remaining terga with preapical seta row and a few, inconspicuous discal setae. Scape without setae except at apex. Fore femur with three or four setae on basal half of ventral margin; mid and hind femora without setae on dorsal margin; tibiae without setae.

Integument. Clypeus smooth and shiny along midline, closely shagreened and moderately shiny elsewhere; frontal lobes and frons slightly shiny, closely shagreened and micropunctate; vertex and occiput a little duller and more densely micropunctate, out blending into frons; malar area and gena shiny, lightly shagreened. Thorax similar to occiput, closely shagreened and moderately shiny, sides shinier. Gaster dull, very closely shagreened and with dull micropunctures.

Color. Head, including scape, and thorax bright ferruginous; gaster blackish; flagellum and legs dark brown.

Type Material
Holotype and four paratype workers: Chile, Prov. Santiago: Fun do Santa Laura, near Cuesta Ia Dormida, 20 Oct. 1971 (J. H. Hunt, #453), all in.

Etymology
The Latin, hypocritus, mime or dissembler, because of the similarity to such species as goetschi and tener.
