Diagnosis.

Distance between apex of marginal cell and apex of fore wing 0.3-0.5 × vein 1-R1 and vertex finely rugulose; five-six apical antennal segments of ♀ suddenly small and moniliform compared to more basal segments (Fig. 192 ); ocelli often rather small (POL 0.8-1.0 × width of posterior ocellus; Fig. 188 ); third tergite of metasoma flattened in lateral view (Fig. 185 ); second submarginal cell of fore wing rather small (Fig. 182 ); anterior half of vein 1-M yellow; vein r 0.3-0.4 × vein 3-SR; head moderately emarginate medio-posteriorly (Fig. 188 ); hind femur comparatively stout; inner tooth of mandible minute, 0.2 × apical tooth; temple matt; hypopygium of ♀ ivory or brownish yellow; second submarginal cell smaller; face and clypeus frequently ivory. Phanerotoma lepta is similar to small P. leucobasis , but the ocelli are smaller, the apical antennal segments becoming suddenly smaller, head is less emarginate medio-posteriorly, third metasomal tergite is rather flat and angle of vein 2-SR with 3-SR is smaller.

Description.

Female, holotype, length of body (excluding ovipositor) 3.7 mm; antenna 2.75 mm; fore wing 2.8 mm; visible part of ovipositor sheath 0.3 mm (sparsely erect setose).

Head. Width 1.5 × median length in anterior view and part of head above eye in lateral view 0.3 × height of eye (Fig. 190 ); antenna with 23 segments and slightly shorter than fore wing, five-six apical antennal segments suddenly (compared to more basal segments) small and moniliform (Fig. 192 ), with short bristle apically and apical segment without distinct spine, third, fourth and penultimate segments 2.4, 2.6 and 1.0 × longer than wide in lateral view, respectively; area of stemmaticum granulate; OOL: diameter of posterior ocellus: POL = 17: 5: 4; length of eye twice temple in dorsal view (Fig. 188 ); frons curved rugulose medially, rugose laterally and without distinct median carina; vertex aciculate and with satin sheen; temple finely and densely rugulose and rather dull; face finely rugose and with small median bump and rather shiny; clypeus superficially granulate, rather shiny and 0.8 × minimum width of face, intertentorial distance 2.4 × minimum width between clypeus and eye (Fig. 189 ), long erect setose and with three minute teeth medio-ventrally; eye medium-sized, strongly convex and in lateral view 1.3 × wider than temple (measured medially; Fig. 190 ), in anterior view its height 0.7 × minimum width of face; upper condyle of mandible near lower level of eyes (Fig. 189 ); malar space aciculate, with satin sheen and 0.6 × as long as basal width of mandible; lower tooth of mandible 0.2 × as long as apical tooth (Fig. 193 ).

Mesosoma (Figs 179 , 183 ). Length 1.5 × its width in lateral view; side of pronotum rugose; propleuron posteriorly evenly convex; mesosternum largely granulate and rather shiny; mesoscutum densely and finely reticulate-rugulose; scutellum distinctly granulate and rather matt; notauli hardly indicated; scutellar sulcus wide medially and narrow laterally, with nine carinae (Fig. 183 ); metanotum with median carina anteriorly and finely serrate posteriorly; propodeum rugose, medially with transverse carina, but no median carina, and latero-posteriorly weakly tuberculate. Wings. Fore wing 2.7 × longer than its maximum width; length of 1-R1 1.1 × as long as pterostigma; distance between wing apex and marginal cell apex 0.45 × length of vein 1-R1; r issued far beyond middle of pterostigma and 0.3 × 3-SR; 2-SR hardly curved and distally slightly converging to posterior margin of pterostigma (Fig. 182 ); SR1 straight; 2-SR+M indistinct, because of narrowly antefurcal m-cu; parastigma large; 1-CU1 0.5 × as long as vein 2-CU1, cu-a 0.8 × 1-CU1; r:3-SR:SR1 = 3:11:40; 2-SR:3-SR:r-m = 20:11:7; r-m reclivous; 2-M hardly curved (Fig. 182 ). Hind wing: M+CU:1-M:1r-m = 27:30:10. Legs. Hind femur matt, 3.6 × as long as wide and widened submedially; middle tibia with small ivory blister; inner spur of middle tibia 0.4 × its basitarsus; hind tibia moderately wide medially (Fig. 186 ); hind coxa largely coriaceous and rather matt.

Metasoma (Figs 184 , 185 ). Elliptical in dorsal view, 1.7 × as long as wide and 1.4 × as long as mesosoma; first and second tergites, as basal half of third tergite, densely and coarsely longitudinally rugose; second metasomal suture medium-sized; third tergite 1.6 × longer than second tergite and laterally curved, in lateral view rather flat, apical half rugulose-coriaceous and with satin sheen (Fig. 185 ), lateral lamella narrow, wider and not protruding latero-apically and medio-apically truncate and rather wide; ovipositor sheath parallel-sided, apically narrow (Fig. 185 ), its visible part 0.09 × as long as fore wing and 0.15 × metasomal carapace and sparsely setose part 0.06 × fore wing and with erect setae; hypopygium with medium-sized up curved apical triangle, apically without spine and densely setose (Fig. 185 ).

Colour. Pale brownish yellow (including ovipositor sheath); apex of antenna and apex of hind tibia somewhat darkened; stemmaticum dark brown; face, clypeus, prothorax, tegulae, remainder of legs and metasoma ventrally ivory; parastigma and pterostigma (but basally pale yellowish) pale brownish; wing membrane slightly brownish below pterostigma; veins 1-M and m-cu of fore wing pale yellowish.

Male.

Similar to female with hind femur similar or slightly inflated (Fig. 181 ), antennal segments slender and elongate, apical segments bristly apically (Fig. 180 ).

Variations.

Length of fore wing of ♀ 1.7-2.8 mm, of ♂ 1.6-2.4 mm; vein 1-M of fore wing and parastigma yellowish, brown or largely dark brown.

Distribution.

United Arab Emirates, Yemen.

Biology.

Unknown.

Etymology.

Named derived from leptos (Greek for fine, small, thin or delicate) because of the small and delicate apical antennal segments of the female.
