Stelis broemelingi View in CoL , n. sp.
( Figs. 4 View FIGURES 1 – 10 , 14 View FIGURES 11 – 20 , 24 View FIGURES 21 – 30 , 34 View FIGURES 31 – 40 )
Diagnosis. The relatively impunctate frons and small ocelli distinguish this species from all other North American Stelis . Additional characters that distinguish S. broemelingi are the combination of the white facial marks, brown tegula, and partial apical pubescent bands on the terga. Many characteristics of this species resemble those of S. palmarum Timberlake , but the smaller ocelli, sparsely punctate frons and larger size of S. broemelingi are diagnostic.
Description. Female. Length 5 mm; forewing length 4.5 mm long. Black; following reddish brown: mouthparts, mandible medially, apically on femora; tegula brown; creamy-white band along inner orbit of compound eye, long bar behind compound eye extending behind lateral ocelli, spot laterally on anterior margin of scutum, pronotal lobe, spot on tegula, bases of tibiae, T1 – T4 with four spots each on half apical margins, T5 with two medially joined apical spots. Pubescence mostly white, scraggly, thicker on face, gena, sterna; terga laterally with apical hair bands, medially becoming single row of widely spaced hair; T6 with darker setae on apical onethird extending over margin lighter, shorter, more dense hairs filling apical groove; S1 – S5 with distinct apical hair bands, S6 with dense, short hair on apical margin. Punctation not uniform; clypeus with numerous small punctures separated by shiny areas; area below median ocellus, mostly impunctate with scattered, large shallow punctures; vertex more densely pitted; gena similar to clypeus, rest of head; mesosoma with moderate-sized punctures separated by about their diameter; basal zone of propodeum with large lateral cells, medially with large punctures, impunctate on posterior face of propodeal enclosure; terga with large separate punctures, except those on T6, closer, contiguous on apical 1/4; S1 – S4 similar to terga; punctures on S5 smaller, denser; punctures on S6 minute, surface shagreened. Head broader (1.2X) than long, genal width slightly less than width of compound eye; ocelli quite small about twice diameter of surrounding punctures, interocellar area swollen, lateral ocelli on a slant; IOD = OOD, IOD> (1.4X) LOPD, IOD> (2X) LMOD, DLID> (3X) BLID; pronotal lobe with raised anterior lamella; in lateral view terga crimped subapically, bowed as seen in lateral view, apical impunctate margins lamella-like; T6 broader than long, pseudomargin apically carinate, round ( Fig. 14 View FIGURES 11 – 20 ); S6 elongate, top broadly rounded, extending beyond apical margin of T6 by length of ultimate tarsomere.
Male. Similar to female except: S1 with subapical lamella; S2, S3 with large contiguous punctures, apical margins depressed ( Fig. 24 View FIGURES 21 – 30 ); S4 with narrow, short-toothed median comb 1/4 width of sternum ( Fig. 34 View FIGURES 31 – 40 ); S5 nearly truncate apically, only shallowly concave; S6 apically produced to broad point; S7 with small median point.

Holotype deposited in BBSL, paratypes in AMNH, BBSL, FSCA, LACM, UAIC, UCDC.
Variation. Some females are larger, up to 9 mm long.
Biology. Only the floral associations mentioned in the type material are known. The host remains unknown.
Distribution. Apparently restricted to southern Arizona where it is active from spring to late summer.
Etymology. Named in recognition of Derek Broemeling, who contributed to our knowledge of cleptoparasitic bees, and whose assistance in developing the U.S. Pollinating Insects Collection is much appreciated.
