Stelis anasazi View in CoL , n. sp.
( Figs. 8 View FIGURES 1 – 10 , 18 View FIGURES 11 – 20 , 28 View FIGURES 21 – 30 , 38 View FIGURES 31 – 40 )
Diagnosis. Stelis anasazi can be distinguished from all other Nearctic Stelis except S. permaculata (Cockerell) , S. ashmeadiellae Timberlake , and S. robertsoni Timberlake by the combination of: scutellum overhanging metanotum, face and vertex with white maculations, and female S6 elongate, trowel-shaped. From these three related species it can be separated by the combination of: tegula dark brown or black without white maculation, female T6 rounded apically ( Fig. 18 View FIGURES 11 – 20 ), and male S4 comb with margin rounded ( Fig. 38 View FIGURES 31 – 40 ).
Description. Female. Length 5mm, anterior wing 4mm long. Black; mandible medially reddish; whitish markings on the following: narrow stripe along inner margin of compound eye, spot on post ocular area, hindtibia basally, T1 – T3 apically. Pubescence white, on head, mesosoma plumose not thick, clypeus with short erect pile, reddish apically, terga with short sparse hair, laterally plumose, more dense; T6 with more erect setae than preceding terga, apical margin with dense band of long and short pile; sterna, except S6, with thicker plumose hair, apically with distinct hair bands. Punctation coarse, punctures small, deep, close on most of body; punctures laterally on terga close, deep, area between punctures dull. Head wider (1.1X) than long; mouthparts short, not extending beyond fossa in repose; clypeal margin crenulate; compound eyes converging basally, DLID>(1.2X) BLID; eye wider (1.1X) than gena in lateral view; frons not bulging anterior to midocellus; ocelli not reduced; IOD <(0.8X) OOD <(0.9X) OPD> (1.5X) LOPD, IOD> (2.0X) LMOD; pronotal lobe with low indistinct carina; anterior surface of mesepisternum not concave; basal zone of propodeum with pitting complete, cells distinct; apical tibial spurs extremely short, spine-like, apical one larger, apical hindtibial spine thicker, short but distinct; TIB>(1.8X) BAT = TAR; terga lamellate apically, graduli deep, terga bowed in profile; T6 angulate laterally, depressed subapically, punctures contiguous, deep groove between pseudo and true apical margin ( Fig. 18 View FIGURES 11 – 20 ); S6 flared apically, trowel-shaped, apical margin reflexed, thickened.
Male. About as in female except: white spots larger, apically on scutum, on all tibiae, T4; punctures on T6, T7 denser, contiguous, surface dull; S3 flat with median depression ( Fig. 28 View FIGURES 21 – 30 ); S4 with tiny bow-shaped median comb ( Fig. 38 View FIGURES 31 – 40 ); S5 depressed, impunctate medially.

Variation. The extent of white markings varies slightly among the type material, in particular there is sometimes a small lateral mark on T4. Material from other locations varies in the extent of white markings and the density of the punctation. In occasional specimens the tegula is dark brown.
Biology. Stelis anasazi has been reared from nests of Heriades carinatus (Cresson) in Utah and southern Nevada.
Distribution. Stelis anasazi is primarily found in the Great Basin of Utah and Nevada but its distribution extends south to Arizona and west to the foothills of the Sierra Nevada.
Etymology. Named for the Anasazi , an ancient culture who lived in the Colorado Plateau of the Four Corners region.
