Anthophora (Micranthophora) parkeri ( holotype: ♂; Corn Springs Campground, 0.4 km ESE, Corn Springs Wash, California, USA; coll. M.C. Orr, 9 Apr. 2014, at Bebbia juncea ; BBSL, BBSL920050 / HOLO106 ) .

Verbatim: “ USA:CA Riverside Co. Corn Springs Campground, 0.4 km ESE; Corn Springs Wash N33.6244 W115.3216 9 Apr 2014 M.C. Orr Bebbia juncea BBSL920050” “ HOLOTYPE Anthophora parkeri male Orr BBSL920050.”

Diagnosis. Males may be determined by the following character combination: scutum shiny, with impunctate areas; basitibial plate present; T5–T6 lacking appressed setae; and T7 with strong medial longitudinal carina, lateral projections short and blunted, and medial projections broadly separated and narrowly rounded at apices ( Fig. 61E ). Females may be determined by the following character combination: facial maculations yellow; clypeal maculation an inverted-T that narrows gradually from rim to top of clypeus, almost triangular in shape ( Fig. 41E ); supraclypeal maculation almost always present, but form highly variable; scape immaculate; scutum shiny, with impunctate areas; T1–T5 covered with appressed setae; and anal fimbria light, tan to orangish.

Male description. Head: Facial maculations pale yellow. Galea reaching past rear of foretrochanter in repose; amber to light brown; weakly tessellate, with clear reflections. Mandible with inferior tooth ovular to weakly triangular, running roughly parallel to main blade; maculated from base to about middle of inferior tooth ( Fig. 51E ). Labral rim tridentate; fully maculated. Clypeal maculation a band, rarely reaching lateral sides, quite variably filling half or less of clypeal height medially ( Fig. 51E ); punctation only slightly sparser within maculation than without. Paraocular area almost always immaculate; slight mark if present. Supraclypeal area usually immaculate; at most with very minute maculation. Scape almost always maculated; quite variable in extent. Mesosoma: Scutum shiny; with distinct impunctate areas. Tegula transparent, clear to yellow-orange. Basitibial plate present; distinct. Metasoma: T1–T4 covered in appressed setae, uncommonly absent in narrow basal zones; T5–T6 without appressed setae. Terga moderately to weakly tessellate, often with some weak reflections; only sometimes apparent through appressed setae. Tergal rims relatively transparent, tan to light brown. Male T7 ( Fig. 61E ) with strong medial longitudinal carina, unobscured; lateral projections weakly recurved, blunt flanges; medial projections long, somewhat truncated apically. Male S5 ( Figs. 38A, 38C ) setal arrangement unremarkable, without large, distinctive patches, at most longer along rim. Male S6 ( Fig. 38A ) clearly medially emarginate. Male S7 ( Fig. 66E ) with setae fully banding S7 around midpoint of length; widening from midpoint to tip, apical half widest near rounded lateral tips; apical half vaguely resembling cat head, rim broadly emarginate between lateral tips. Male S8 ( Fig. 71E ) lateral projections distinct; medial projection narrowing to tip, apically emarginate. Male genital capsule ( Fig. 76E ) 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 relatively unmodified, concave or straight; tip, in profile, weakly pointed and strongly curved ventrally; gonostylus tip position slightly exceeding that of gonocoxite, measured from above along primary axis of latter. Pubescence: See Fig. 56E . Appears light to medium gray overall. Setae white to off-white, except as follows: leg inner faces light orange; tergal basal zones dark if present.

Female similar to male, except: Head: Facial maculations often somewhat darker yellow. Galea often darker, medium brown; moderately tessellate, duller. Mandible with inferior tooth ridge-like, weakly angled off main blade ( Fig. 41E ). Clypeal maculation an inverted-T, usually reaching lateral sides, narrowing gradually from rim to top of clypeus, almost triangular in shape ( Fig. 41E ); punctation denser in upper half of maculation. Paraocular area almost always immaculate; slight dot if present. Supraclypeal maculation more often present; larger, typically transverse. Mesosoma: Midtibial spur apically curved; tan to orange. Basitibial plate circular distally, teardropped overall. Metasoma: T1–T4 covered in appressed setae; T5 with extensive appressed setae. Terga less tessellate, with stronger reflections; sometimes apparent through appressed setae. Tergal rims more transparent, tan to clear. T4 impunctate rim of short to moderate length medially, at most slightly triangular. Anal fimbria triangular, covering third to slightly under half of T5 length medially. Pubescence: See Fig. 46E . Vertex and scutum regularly with dark intermixing; hindbasitarsal brush orange to light brown; anal fimbria orangish.

Distribution. See Fig. 22 . Present in USA: California, Arizona, Nevada; Mexico: Baja California Norte, likely Sonora. Found almost exclusively in Sonoran and Mojave Deserts. Ecoregional habitance is as follows, based on 265 specimen records: 4 ecoregions total: Sonoran Desert (154=56.9%), Mojave Desert (111=41.8%), California coastal sage and chaparral (1≤1%), California montane chaparral and woodlands (1≤1%).

Phenology. Recorded from March–July, October, almost exclusively spring, most common in April–May. Univoltine, single October record from Riverside County (CA) possibly mislabeled or opportunistic emergence.

Nesting biology. The first author has observed this species nesting in sandy washes four times. A fifth female has been observed trying, and failing, to excavate into a hard-packed road of silty/sandy composition. Further details on these new records will be presented in a subsequent review of the group’s nesting biology.

Floral specialization. Specialist on Asteraceae , plausibly narrowly specialized on Bebbia juncea . Primary recorded visits by 77 females include: Family Asteraceae (88%); Genus Bebbia (67%), Chaenactis (11%); Species Bebbia juncea (67%). 137 total floral records from eight families include: Asteraceae (53 ♂ 69 ♀): Bebbia juncea 30 ♂ 29 ♀, Bebbia sp. 22 ♀, Bidens pilosa 1 ♂, Chaenactis fremontii 1 ♀, Chaenactis sp. 3 ♂ 4 ♀, Chaenactis stevioides 4 ♀, Encelia farinosa 8 ♂, Encelia sp. 1 ♂, Geraea canescens 1 ♀, Malacothrix sp. 2 ♂, Palafoxia arida 1 ♂ 2 ♀, Palafoxia linearis 2 ♂ 4 ♀, Palafoxia sp. 1 ♂, Stephanomeria sp. 4 ♂ 1 ♀, Bignoniaceae (1 ♂): Chilopsis linearis 1 ♂, Boraginaceae (2 ♂ 1 ♀): Nama hispidum 1 ♀, Phacelia sp. 2 ♂, Fabaceae (2 ♂ 3 ♀): Dalea schottii 1 ♂, Dalea sp. 1 ♂, Dalea spinosa 1 ♀, Prosopis glandulosa 1 ♀, Psorothamnus schottii 1 ♀, Malvaceae (1 ♂ 3 ♀): Sphaeralcea sp. 1 ♂ 3 ♀, Nyctaginaceae (1 ♀): Abronia villosa 1 ♀, Onagraceae (1 ♀): Oenothera sp. 1 ♀, Polygonaceae (1 ♂): Eriogonum sp. 1 ♂.

Etymology. This species is named for F.D. Parker and his ever-efficient husband/assistant, T. McIntyre, whose expertly-placed pan traps likely control species’ abundance in the greater Palm Springs, CA area. This species was apparently first recognized by Timberlake, who gave it the unpublished name “vanduzeei.”

Comments. Unfortunately, the material for A. pachyodonta and A. parkeri were reversed in the reference collection MCO originally used for determinations, this confirmed by the types. Identifications prior to 2015 are suspect.
