Presoter yusufi Mahmood, Quicke & Papp, sp. nov. (Figs 1–3 a/b)

Female: Body length 5.8 mm, forewing length 5.9 mm, length of exerted part of ovipositor 1.7 mm.

Head: Antennae longer than head, mesosoma and first two tergites of metasoma; with 42 flagellomeres; terminal flagellomere pointed, simple (not acuminate), as long as wide, penultimate flagellomere 1.33 times longer than wide, 1st flagellomere 1.2 and 1.4 times longer than second and third; scape 4.0 times as long as pedicel. Inter-tentorial distance 0.8 times tentorio-ocular distance. Face setose, micro sculptured (aciculate) and additionally with some punctures, with median longitudinal carina, transverse in frontal view (at least 1.8 times wider than high) (Fig. 1 b). Width of face 0.55 times width of head. Head smooth and shiny, cubic in dorsal view, as broad as long, with frontal suture, head extended dorsally considerably above to level of eyes (Fig. 1 c). Eye height 0.8 times width of face, eye glabrous in dorsal view. Frons evenly and finely with short setosity. Temple not strongly receding behind eyes. Stemmaticum with round edges, posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus to eye = 1.0:1.0:2.75.

Mesosoma: Almost entirely smooth and shiny, sparsely setose (Fig. 1 f), mostly yellow brown, 1.5 times longer than maximally high. Pronotum completely smooth laterally. Mesoscutum shiny; notauli distinctly impressed on mesoscutum. Mesopleural sulcus absent. Scutellar sulcus narrow and finely crenulate. Propodeum smooth shiny with foveae on anterolateral corners and with sparsely distributed setae.

Wings: Forewing (Fig. 2 b). Ratio of length of veins SR1:3-SR:r = 5.8:4.0:1.0. Ratio of length of veins 2- SR:3-SR:r-m=1.2:2.4:1.0. Veins 2-M & 3-SR, 3.1 times & 2.4 times as long as r-m, respectively. Vein 1-M straight. Vein 1-SR+M straight. Vein cu-a interstitial to marginally post furcal. Veins 1-M and m-cu distinctly curving towards anterior wing margin. Ratio of length of veins 1-M:m-cu=1.3:1.0. Vein 3-CU1 curved posteriorly. Vein CU1a curved interiorly. Hind wing. Evenly setose. Vein SC+R1 1.6 times length of 1r-m.

Legs: Claw simple (without basal lobe), fore and mid tarsal claw strongly curved (Fig. 2 c). Apex of fore tibia with one spur. Ratio of length of hind femur:tibia:basitarsus = 2.0:2.6:1.0. Hind femur (excluding trochantellus) 2.7 times longer than maximally deep, broadest at middle, rather flattened laterally, sparsely setose. Hind tibia entirely setose. Hind basitarsus 5 times longer than maximally deep. Outer hind tibial spur reaching approximately 0.5 of distance along basitarsus.

Metasoma: Sparsely setose and foveolate (Fig. 2 d). First tergite with well developed dorso-lateral carinae (Fig. 2 e), sparsely setose, weakly crenulated. Second tergite entirely setose, finely and weakly crenulated, with a mid-basal triangular area which is produced posteriorly into a mid-longitudinal carina and with clearly defined antero-lateral areas (Fig. 2 f). Second metasomal suture narrow. Tergites 3-5 with clearly defined antero-lateral areas (Fig. 2 d). Poster-lateral margin of fifth tergite with small denticulate region laterally (Fig. 3 a). Ovipositor sheath long. Ovipositor with a pre-apical dorsal nodus and lower valve of ovipositor with teeth (Fig. 3 b).

Coloration: Yellow-brown except antennae, stemmaticum, apex of mandible, tarsal claw and ovipositor sheath which are black. Wings almost clear, venation and pterostigma brownish.

Etymology: Named after Dr Mohammad Yusuf, a colleague of KM for his contribution on taxonomic research in Pakistan.
