These are images of a Spider Wasp that I believe is most likely a male Psorthaspis planata.

ID info:
Gender - 11 flagellomeres and 7 abdominal segments = ♂
Keying to Subfamily in the Family Pompilidae: (1)
1aa. - Metasomal sternum 2 without distinct sharp transverse groove, but sometimes with wide shallow transverse depression
1cc. - Hind metatibia usually without a series of teeth along dorsal margin
1dd. - Metatibia with apical spine-like setae usually of different lengths and splayed
1ff. - Fore wing with vein Cu1 usually distinctly deflected downward at base, such that the second discal cell (2D) has a posterior "pocket" = 3
3a. - Metatibia with apical spine-like setae long, of irregular lengths and spacing, the setae distinctly splayed
3b. - Fore wing with vein Cu1 usually distinctly deflected downward at base
3f. - Labrum often concealed below clypeus, but labrum sometimes partially exposed = Subfamily Pompilinae
Keying to Genus in the Subfamily Pompinlinae (males):
1aa. - Fore wing with three sub-marginal cells (or sometimes two, in other genera) = 3
3aa. - Transverse median (cu-a) and anal veins (A) of hind wing not clearly separated, forming a continuous broad arc which curves up to meet media = 7
7aa. - Anal lobe smaller, at most slightly more than half the length of the sub-median cell
7bb. - Body only occasionally as setose = 8
8a. - Propodeum not produced posterolaterally into sharp, conical processes, occasionally the posterior angles broadly produced = 9
9aa. - Postnotum a transverse band of variable width, with nearly parallel anterior and posterior margins, or broadened at the midline, or occasionally practically absent
9bb. - Anal vein (A) of hind wing meeting media before the origin of the cubitus (Cu); abdomen without scale-like pubescence on Tl; other characters variable = 13
13aa. - Second recurrent vein (2m-cu) arising on the subdiscoidal vein about or somewhat less than half the distance from the base of the sub-discoidal vein to the outer wing margin = 18
18aa. - Fore wings with three sub-marginal cells (This seems redundant, but cross-references other couplet routes for other genera.) = 19
19a. - Anterior margin of clypeus convexly rounded, the clypeus not usually more than about 1.7X as wide as high
19b. - Propodeum with the slope rather flat in front, abruptly declivous behind, often prominent on the sides of the declivity
19c. - Pronotum rather long, often as long or longer than mesoscutum, its posterior margin weakly arcuate to nearly straight
19d. - Antennae segments short, third segment less than 2X as long as thick = genus Psorthaspis Banks 1912
Keying to Species in the Genus Psorthaspis (males): (Bradley 1944) [cite:?????]
1b. - Wings uniformly dark fuscous; vestiture dark, the tomentum with purple, blue or green reflections = 2
2b. - Surface of vertex between and behind posterior ocelli forming a strongly elevated, somewhat acute hump = species planata Fox (1892)
