Comments and diagnosis. Eumenes coyotae Bohart, 1948 , is identified by the following features: body with predominantly ferrugineous background color; T1 long, slender, and with reduced, almost absent, punctation; and the basal half of T2 also with reduced punctation, while on the apical half the punctation becomes coarse and dense. This species is apparently restricted to Baja California Sur.

Redescription. Holotype Eumenes coyotae Bohart, 1948 ( Fig. 7 )

Male. Color, head: Yellow marks as follows: mandibles; inter-antennal region; a broad band on inner margin of compound eye that goes from the base of the clypeus to the ocular sinus; a band adjacent to the external margin of the compound eye. Ocelli region with black mark. Frons and vertex (behind the yellow band on gena) ferrugineous. Antenna ferrugineous-yellowish. Mesosoma: predominantly ferrugineous, with yellow marks as follows: broad band along the pronotal carina on dorsal face of pronotum; a mark on upper half of mesepisternum, adjacent to the mesepimeron; parategula; a band on apical third of scutellum; metanotum; marks on femora, almost entirely tibiae and tarsi, although the distal tarsi become brownish darker. Metasoma: ferrugineous, except for a black mark on basal region; with yellow marks as follows: narrow transverse band on apex of T1; broad band on each side of T2 and a band occupying the apical third of it; apical half of S2; T3–T7 and S3–S7 (with a transverse dark band on apex). Small black mark on the base of T2. Wings: Hyaline, with costal, medial and submedial cells yellowish. Pterostigma and veins dark brownish.

Pubescence, head: Golden and moderately long pubescence on frons, vertex and occipital region. Clypeus and gena with short and whitish pubescence, better observed in oblique view. Scape with short (as in clypeus) golden pubescence. Mesosoma: Pronotum, mesoscutum, scutellum and metanotum with short golden pubescence. Mesepisternum and posterior face of propodeum with whitish pubescence, better observed in oblique view. On posterior face of propodeum the pubescence is longer, as in frons. Metasoma: Golden and shortest pubescence along body, except for some scattered bristles on ventral face of T1 and apex of each segment.

Surface of integument, head: Clypeus with punctation mostly on basal two-thirds; frons and vertex with coarse and dense punctation, becoming sparser behind the ocelli. Mesosoma: Coarse and dense punctation as on frons. Metasoma: T1 with reduced punctation, at least with some more evident on apex; basal half of T2 with weak punctation, very sparse, while the apical half the punctures becomes coarse and clearly denser. S2 with evident punctation on lateral portions. T3–T7 and S3–S7 without evident punctation.

Structure, head: Clypeus convex, longer than wide. Apex of clypeus concave, forming two projections with carina on apex of each one. Inter-antennal region longitudinally cariniform, narrow than the antennal socket. Lateral ocelli closer to the compound eyes than to each other. Occipital carina well developed, not angled on middle area of gena. F11 short, without longitudinal carina on dorsal surface, with the apex pointed and surpassing the apical edge of F8 ( Fig. 81 ). Ventral surface with microscopic bristles on apex. Mesosoma: Pronotal carina present dorsally, weak developed, while on lateral portion it becomes more developed. Pronotal fovea present. Posterior projection of tegula weak developed, rounded; parategula lamelliform; posterior face of propodeum moderately concave. Metasoma: T1 more than three times longer than wide, slender, weakly swollen in dorsal view ( Fig. 31 ). T2 globose, longer than wide ( Fig. 47 ), with the basal angle (in lateral view) rising up abruptly. Apical lamella present and becoming reduced towards lateral margins. S7 flattened apically.

Male genitalia: Aedeagus as on figure 97a, b. Paramere ( Fig. 97c ) with long bristles on middle region of the gonostyle; cuspis with thin, long and dense pubescence; digitus slender on apex, with short bristles on ventral surface ( Fig. 114 ); volsella with short (shorter than on cuspis) and denser pubescence; distal lobe with a few erect bristles on apex.

Female: Black marks as follows: marks on frons more developed, reaching the vertex; small spot on mesepimeron; narrow, sticklike band longitudinally on mesoscutum and a small spot on the base; broad transverse band between two yellow band on middle area. Pubescence and punctation as on males. Labrum with the apex rounded; clypeus as long as wide; inter-antennal region as long as the antennal socket. All other structure as in males.
