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.

Description

Female (5 specimens)

MEASUREMENTS. B 19 – 20; F 13 – 14; ML 0.4; CT 1.6; OOL 0.1; POL 1.1; FI 0.6; Fl1 – 2 1.9; Fl20 2.25; AI 0.9; CI 0.4; ICI 0.35; SDI 1.3; NI 2.7.

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.
