Diagnosis

Moderately sized and yellow overall, including antennae and legs, pterostigma yellow, bordered posteriorly with black; mandible hardly twisted; clypeus strongly convex in profile, ventral margin blunt and in-turned; face 1.2 × as high as wide; antenna with 58 flagellomeres; mesoscutum with exceptionally long notauli distinct over its entire length; mesopleuron and metapleuron nearly smooth, with very slight fine rugosity ventrally; propodeum nearly smooth anteriorly, coarsely rugose-reticulate posteriorly; proximal sclerite comma-shaped with very long distal extension.

Etymology

Named in reference to the country of Saudi Arabia, where the type specimen was collected.

COLOUR. Yellow overall, including antennae and legs, with posterior half of T1–3 slightly darker; ovipositor sheath dark brown to black, pterostigma yellow, borderd posteriorly with black, wing veins dark brown to black, except sub-basal part of Rs+2 r which is yellow margined dorsally with black, wing sclerite light orange to yellow; mandibular teeth black.

HEAD. Mandible short and stout, hardly twisted, upper tooth barely longer than lower tooth, bare, without groove on outer surface; clypeus superficially punctate medially, exceptionally convex in profile, ventral margin blunt and in-turned; face 1.2 × as high as wide, smooth; gena relatively broad and slightly swollen behind eyes; occipital carina complete and thin; antenna long and slender, with 58 flagellomeres.

MESOSOMA. Pronotum, mesoscutum, mesopleuron and metapleuron nearly smooth and shiny, with very slight fine rugosity especially ventrally; epicnemial carina distinct to level of ventral corner of pronotum; postpectal carina distinct and complete; notauli weak, but exceptionally long, extending over entire mesoscutum length; scutellum densely, finely punctate, carinate to near apex; basal transverse carina of propodeum sharply distinct; anterior area of propodeum smooth, posterior area finely transversely striate, concave postero-medially.

WINGS. Disco-submarginal cell of fore wing with well developed fenestra; proximal sclerite commashaped and connected to very long distal sclerite extending to Rs+2r; central sclerite totally absent; Rs+2 r more or less straight, sub-basally thickened; cu-a subopposite to Rs & M; hind wing with 7 distal hamuli on R1.

LEGS. Fore tibia sparsely setose and with a crown of apical brownish spines; hind coxa in profile about 1.5 × as long as high; hind tarsal claws symmetrical, with 8 subequal teeth, that are slightly shorter than claw length.

METASOMA. Stout, widened posteriorly; thyridium slender, extending to slightly more than basal third of T2; ovipositor hardly reaching beyond metasomal apex, with dark brown sheath.

Male

Unknown.

BOLD Identification Number

ADB3498.

Remarks

This species is morphologically exceptional within Enicospilus . The hardly twisted mandibles, strongly convex clypeus and very long notauli are characters which occur rarely in the genus. Their combination makes E. arabicus sp. nov. unique.

Distribution

Saudi Arabia.
