Anthophora phenax ( Cockerell, 1906) View in CoL : 66.

Diagnosis. This species is unusually distinctive. All appressed metasomal setae in both sexes are longer and more strongly branched than is seen in any other A. ( Micranthophora ), and this is further emphasized by their sparseness (note that A. columbariae and similar species approach this setal form). Males may be otherwise determined by the following character combination: labral rim rounded; mandible with inferior tooth absent ( Fig. 52B View FIGURE 52 ); face maculated, creamy white, almost entirely to antennal fossae ( Fig. 52B View FIGURE 52 ); and clypeus nearly fully impunctate. Females may be otherwise determined by the following character combination: labrum entirely black or nearly so; mandible with inferior tooth reduced to slight nub ( Fig. 42B View FIGURE 42 ); clypeal punctures unusually large; and pygidial plate unusually narrow, sides forming an angle of less than 30 degrees.

Male description. Head: Head shape atypical for group, superficially more similar to that of A. ( Mystacanthophora ) males ( Fig. 52B View FIGURE 52 ). Facial maculations white to slightly off-white. Galea reaching back past rear of foretrochanter in repose; dark to medium brown; moderately to weakly tessellate and often smoother near base, with weak to moderate reflections. Mandible with inferior tooth absent; maculated from base to around middle of mandible ( Fig. 52B View FIGURE 52 ). Labral rim rounded; fully maculated. Clypeus fully maculated ( Fig. 52B View FIGURE 52 ); almost entirely impunctate throughout. Paraocular area maculated; from base to at least supraclypeus, often laterally as well. Supraclypeal area maculated; transverse bar linking paraocular maculations. Scape maculated; almost fully along length below, somewhat amorphously. Mesosoma: Scutum shiny; with large impunctate areas. Tegula translucent to opaque, dark to medium brown. Basitibial plate functionally absent; extremely weak and no more than a bump, sometimes absent, always obscured by setae unless worn off. Metasoma: T1 covered in sparse appressed setae; T2–T3 almost always with apical appressed setal bands; T4 usually with weaker apical appressed setal band, broadly interrupted medially; T5–T6 often without appressed setae. Terga weakly tessellate to smooth between punctures, with strong reflections; apparent through appressed setae. Tergal rims translucent, medium to dark brown. Male T7 ( Fig. 62B View FIGURE 62 ) with weak medial longitudinal carina; lateral projections absent; medial projections widely separated, moderately long, narrow, sharp. Male S5 ( Figs. 38A, 38C View FIGURE 38 ) setal arrangement unremarkable, without large, distinctive patches, at most longer along rim. Male S6 resembling Fig 38A View FIGURE 38 , clearly medially emarginate to a rounded or pointed middle, but shallower overall. Male S7 ( Fig. 67B View FIGURE 67 ) with setae fully banding S7 around midpoint of length; widening from midpoint to tip, apical half widest clearly before rounded lateral tips; apical half greatly expanded into broad hexagon, rim rounded outward, with slight medial bump. Male S8 ( Fig. 72B View FIGURE 72 ) lateral projections nearly absent; medial projection nearly parallel-sided, nearly entire apically. Male genital capsule ( Fig. 77B View FIGURE 77 ) with outer corners, where gonocoxite tips curve inward, marked by obvious flange of about 90 degrees or greater, best seen in profile; from corner to apex, in profile, gonocoxite with obvious secondary flange or angle; tip, in profile, rounded and weakly curved ventrally; gonostylus tip position slightly exceeding to roughly equaling that of gonocoxite, measured from above along primary axis of latter. Pubescence: See Fig. 57B View FIGURE 57 . Appears dark gray overall. Setae white, except as follows: vertex and scutum with no or little dark; leg inner faces brown; tergal basal zones dark.

Female similar to male, except: Head: Head shape only slightly atypical for group ( Fig. 42B View FIGURE 42 ); superficially somewhat intermediate in form between other A. ( Micranthophora ) and A. ( Mystacanthophora ). Galea usually smoother, shinier. Mandible with inferior tooth reduced to tiny nub, barely angled off main blade; immaculate from base, though with golden apical smear seen in some other subgenera ( Fig. 42B View FIGURE 42 ). Labrum immaculate or with slight maculation at top. Clypeal maculation greatly reduced, thin band or small triangle along rim, not reaching lateral sides, usually filling a third to half of clypeal height ( Fig. 42B View FIGURE 42 ). Paraocular area immaculate. Supraclypeal area immaculate. Scape immaculate. Mesosoma: Midtibial spur apically curved; tan to orange. Basitibial plate circular distally, teardropped overall. Metasoma: T1 covered in appressed setae; T2–T4 usually with apical appressed setal bands, vaguely undulate; usually medially interrupted on T4; T5 with or without appressed setae, typically thinner if present. Terga may be more moderately tessellate. T4 impunctate rim of extended length medially, strongly triangular. Anal fimbria triangular, typically covering third or more but under half of T5 length medially. Pubescence: See Fig. 47B View FIGURE 47 . Hindbasitarsal brush dark brown; anal fimbria dark brown to blackish; sterna intermixed dark and light, S5 mostly dark.

Distribution. See Fig. 25 View FIGURE 25 . Present in USA: Arizona, California, New Mexico, Texas, Nevada; Mexico: Sonora, Baja California Norte, Baja California Sur, likely Chihuahua, possibly Coahuila. Found almost exclusively in Sonoran and Chihuahuan Deserts. Ecoregional habitance is as follows, based on 149 specimen records: 6 ecoregions total: Sonoran Desert (93=62.4%), Chihuahuan Desert (43=28.9%), Mojave Desert (8=5.4%), East Central Texas forests (2=1.3%), Gulf of California xeric scrub (1≤1%), Baja California desert (1≤1%).

Phenology. Recorded from February–June, September–November, primarily spring. Likely bivoltine in western deserts (Mojave, Sonoran Deserts).

Nesting biology. Unknown.

Floral specialization. Plausibly specialist on Boraginaceae , likely preferring Phacelia if so. Originally reported as a potential specialist on Lycium (Solanaceae) ( Moldenke & Neff 1974). However, 15 pollen views strongly suggest it instead uses Boraginaceae primarily or solely; visits to Solanaceae likely resulted from common co-occurrence of the two plant groups. Alternatively, this species may be an eclectic specialist on these two families ( Cane & Sipes 2006). Primary recorded visits by 32 females include: Family Solanaceae (47%), Boraginaceae (41%); Genus Lycium (47%), Phacelia (41%); Species Lycium berlandieri (22%), Phacelia crenulata (13%). 71 total floral records from eight families include: Asclepiadaceae (1 ♂): Asclepias erosa 1 ♂, Asteraceae (5 ♂ 1 ♀): Bebbia juncea 1 ♂ 1 ♀, Pectis papposa 1 ♂, Pluchea sp. 2 ♂, Stephanomeria sp. 1 ♂, Boraginaceae (12 ♂ 13 ♀): Cryptantha maritima 5 ♂, Hydrophyllaceae sp. 5 ♂, Phacelia crenulata 4 ♀, Phacelia sericea 1 ♂, Phacelia sp. 1 ♂ 6 ♀, Phacelia sp. 3 ♀, Fabaceae (2 ♂): Astragalus lentiginosus 1 ♂, Parkinsonia sp. 1 ♂, Lamiaceae (1 ♀): Hyptis emoryi 1 ♀, Plantaginaceae (1 ♂ 1 ♀): Penstemon parryi 1 ♀, Penstemon thurberi 1 ♂, Solanaceae (17 ♂ 15 ♀): Lycium andersonii 1 ♀, Lycium berlandieri 10 ♂ 7 ♀, Lycium pallidum 1 ♀, Lycium sp. 4 ♂ 4 ♀, Lycium torreyi 3 ♂ 2 ♀, Zygophyllaceae (1 ♂ 1 ♀): Larrea tridentata 1 ♂ 1 ♀.

Comments. Examination of the type of A. leucostomella revealed that it is not a synonym of A. phenax , as the genitalia and numerous other aspects do not agree. In fact, it is instead most similar to A. (Mystacanthophora) urbana Cresson, 1878 . As it fits within variation observed in xeric specimens of A. urbana , it does not appear to warrant specific status. Consequently, A. leucostomella is, for now, transferred to A. urbana as a new junior synonym. Anthophora phenax has been found wrapped in the web of an unidentified araneid spider, making it one of few A. ( Micranthophora ) for which there are predation records.
