Specimen labels

Nothing is known about the biology of Dorymyrmex paiute.

Identification

Snelling (1995) - Unicolorous brownish species with greatest EL distinctly shorter than OMD.

The small eyes and lack of pronotal hairs serve to separate this species from all others previously described from North America. Three specimens do possess pronotal hairs, but these hairs are distinctly shorter than the minimum thickness of the antennal scape. In all other species with pronotal hairs, the hairs are as long as, or longer than, the maximum width of the antennal scape. This species is presently known only from the type series.

Description

Worker

(holotype) (mm): HL 0.90; HW 0.81; SL 0.84; EL 0.21; TL 3.0. Indices and ratios: CI 89; SI 97; SI2 110; 0123; OMR 114; IOR 200.

Head broadest at eye level; in frontal view, margins weakly convex and broadly rounded onto venex, venex weakly concave. Eye small, EL 0.90 times OMD, OMD about 0.64 times distance from upper eye margin to level of vertex margin. Mesonotal profile flat or slightly concave; base of propodeum long, distinctly sinuate, posterior tubercle broad at base, sharp. Sculpture and pilosity as described for D. insanus but pronotum without erect hairs (several specimens have one pair of setae that are distinctly shorter than minimum scape thickness).

Color light reddish brown, head more reddish and gaster more brownish; antennae and legs paler.

Paratypes (mm): HL 0.81-0.92; HW 0.71-0.84; SL 0.77-0.87; EL 0.19-0.23; TL 2.9-3.4. Indices and ratios: CI 88-96; SI 93-100; SI2 100-114; 01 22-26; OMR 108-129; IOR 171-200.

Type Material

Holotype and 35 paratype workers: Utah, Washington Co.: Zion National Park, 22July 1932 (W.S. Creighton). Holotype in Los Angeles County Museum of Natural History; paratypes in The Natural History Museum, LACM, Museum of Comparative Zoology, National Museum of Natural History.

Etymology

Named for the Paiute people who formerly occupied the Great Basin region; the name is a noun in apposition.
