Diagnosis
This species is very similar to
O. lasallei
with the frons vertically costate, labrum 12 digitate, and basal area of the wing with similar reduced setation; however in
O. vasquezi
the femora and labiomaxillary complex are brown, the gaster is dark brown with iridescence, and the petiole is slightly longer (1.2×) relative to the hind coxa.
Female.
Length
5.75 mm
.
Colour
: Head and mesosoma blue green with reddish patches on vertex, anterior mesosomal midlobe, lateral sidelobe, axillae and frenal line; ventral mesosoma dark bluish green. Scape yellow; pedicel dark brown; anellus brown; flagellum black. Mandible brown with darker margins and teeth; maxilla and labium brown. Coxae dark blue; Fore wing hyaline; venation pale brown. Petiole dark bluish green; gaster black with blue-purple reflections.
Head
in frontal view subtriangular; head width 1.2× head height; face mostly smooth, upper frons vertically costate to rugose laterally and dorsally; scrobal depression deep, laterally rounded, with transverse costae; dorsal scrobal depressions absent; eyes bare; inter-ocular distance 2.2× eye height; malar space 1.2× eye height; supraclypeal area longer than broad, mostly smooth; clypeus smooth with shallow setose umbilicate punctures; epistomal sulcus vaguely defined; anterior tentorial pit strongly impressed; anteclypeus absent, ventral margin of clypeus broadly rounded. Labrum with 12 digits. Mandibular formula 3:2 [?, mostly hidden]. Palpal formula 3:3. Occiput aciculate, sharply emarginate in dorsal view with abrupt dorsal margin; temples broad. Scape not reaching median ocellus. Pedicel subconical, as broad as F1. Flagellum with 8 funiculars; flagellum length 1.3× head height; F2 broader than pedicel, 1.8× as long as broad, 1.2× as long as F3; following funiculars subequal in length, equal in width; clava subconical.
Mesosoma
length 1.3× height. Mesoscutal midlobe coarsely rugose-areolate, bare; lateral lobe coarsely rugose-areolate; notauli deep. Axilla rugose-areolate, dorsally rounded, on roughly same plane as scutellum; scutoscutellar sulcus broad, regularly foveate, narrowly separated from transscutal articulation medially; scutellar disc slightly longer than broad, coarsely rugose-areolate; frenal line irregularly foveate; frenum rugose-areolate; axillular sulcus absent; axillula areolate. Propodeal disc broadly rounded, without depression or carina, rugose-areolate; callus finely areolate-reticulate, bare; callar nib absent. Prepectus triangular dorsally, strongly narrowed ventrally, sculpture rugose-areolate. Mesepisternum irregularly areolate-reticulate laterally, smooth ventrally, broadly rounded anterior to mid coxa. Upper mesepimeron smooth with longitudinal costae; lower mesepimeron longitudinally costate; transepimeral sulcus weakly impressed. Metepisternum laterally smooth. Propleuron convex, coriaceous. Postpectal carina prominent. Hind coxa 1.9× as long as broad, smooth but weakly reticulate basolaterally; hind femur 6.0× as long as broad, with short, dense setae apically; hind tibia densely setose. Fore wing 2.6× as long as broad, 2.6× as long as mesothorax; basal cell and speculum bare, costal cell and wing disc densely setose; marginal fringe relatively long; submarginal vein with small setae; marginal vein pilose; stigmal vein 4.3X as long as broad, very thin, perpendicular to anterior wing margin; postmarginal vein 3.4× as long as stigmal vein. Hind wing pilose apically, basal third micropilose, costal cell mostly bare except for several setae in extreme apex.
Metasoma
: Petiole cylindrical, linear in profile, 3.0× as long as broad, 1.2× as long as hind coxa, rugose-areolate, anterior carina strong. Antecostal sulcus smooth; acrosternite posteriorly rounded; apical setae of hypopygium with medial patch of short setae. Ovipositor not exposed.
Male.
