Doggerella transversa Mahmood, Quicke & Papp sp. nov. ( Fig. 9 d–f, 22a–f)

Female: Body length 2.5 mm, fore wing length 2.9 mm.

Head: Antenna 24 segmented, ( Fig. 9 d) as long as head, mesosoma and fore half of metasoma, terminal segment pointed, simple (not acuminate), 1.5 times longer than wide, penultimate segment 1.33 times longer than wide, first flagellomere 1.2 and 1.4 times longer than second and third respectively. Scape 3.0 times as long as pedicel. Inter-tentorial distance 1.75 times tentorio-ocular distance. Face setose, transverse in frontal view, 1.3 times wider than high ( Fig. 22 b), width of face 0.43 times width of head. Head entirely coriaceous ( Fig. 22 c), transverse in dorsal view, 1.8 times as broad as long, head extended considerably above to level of eyes. Eye height almost equal to width of face, eye glabrous in dorsal view. Temple strongly receding behind eye. Stemmaticum with round edges, posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus to eye=2.5:1.0:3.5.

Mesosoma: Almost entirely setose ( Fig. 22 d), shiny, 1.4 times longer than maximally high. Pronotum smooth laterally. Mesoscutum setose. Notauli weakly but distinctly impressed, 0.8 of mesoscutum. Mesopleural sulcus absent. Scutellar sulcus narrow and finely crenulate. Propodeum smooth, shiny, with sparsely distributed long setae.

Wings: Fore wing ( Fig. 22 e). Ratio of length of veins SR1:3-SR:r=3.7:1.6:1.0. Ratio of length of veins 2- SR:3-SR:r-m=1.6:1.6:1.0. Veins 2-M & 3-SR, 2.85 times & 1.6 times as long as r-m, respectively. Vein 1-M straight. Vein 1-SR+M straight, distinctly less sclerotized near the origin of 1-SR. Vein cu-a interstitial to marginally post furcal. Veins 1-M and m-cu not distinctly converging. Ratio of length of veins 1-M:m-cu=2.4:1.0. Vein 3- CU1 curved posteriorly. Hind wing. Evenly setose. Vein SC+R1 2.4 times length of 1r-m Vein 1r-m 2.5 times length of R1.

Legs: Claw simple. Ratio of length of hind femur:tibia:basitarsus=2.1:2.7:1.0. Hind femur (excluding trochantellus) 3.0 times longer than maximally deep, rather flattened laterally, entirely setose, broadest at middle. Hind tibia entirely setose. Hind basitarsus 4.0 times longer than maximally deep. Outer hind tibial spur reaching approximately 0.4 of distance along basitarsus.

Metasoma: Sparsely setose and foveolate ( Figs 9 e–f, 22f). First tergite largely setose, weakly crenulated. Second tergite entirely setose, finely and weakly crenulated, 1.2 times longer than third medially. Second metasomal suture narrow. Third tergite entirely setose, crenulated with apical transverse row of long setae. Second and third tergites transverse, second tergite 2.27 times and third tergite 2.64 times as wide apically as long medially. Fourth and fifth tergites entirely setose, crenulated with apical transverse row of long setae. Hypopygium large and protruding beyond apex of tergites. Ovipositor sheath 0.93 mm long, ovipositor with pointed apex, without a distinct nodus, lower valve of ovipositor with no teeth visible at x40 magnification.

Coloration: Head mostly black. Face yellow brown with a black spot above mouth. Eyes brown. Mesosoma black, legs yellow brown. Wings almost clear, venation and pterostigma brownish. Metasoma light to dark brown. Sternites with brown markings

Etymology: Named after its transverse face

Material examined: Holotype: female, Zimbabwe ( Rhodesia), Chishawasha, x.1979, A. Watsham, HNHMB.
