Doggerella cohaerens Mahmood, Quicke & Papp sp. nov. ( Figs 3 c–f, 4a, 14a–f)

Female: Body length 2.7 mm, fore wing length 3.0 mm.

Male: body length 3.25 mm, fore wing length 3.5 mm.

Head: Antenna 25 segmented as long as head, mesosoma and first tergite of metasoma, terminal segment pointed, simple (not acuminate), 2.0 times longer than wide, penultimate segment 2.0 times longer than wide, first flagellomere 1.2 and 1.3 times longer than second and third respectively. Scape 2.5 times as long as pedicel. Intertentorial distance 1.6 times tentorio-ocular distance. Face setose, quadrate in frontal view, as wide as high ( Fig. 14 b), width of face 0.5 times width of head. Head entirely coriaceous ( Figs 3 c, 14c), sub-cubic in dorsal view, 1.5 times as broad as long, head extended considerably above to level of eyes. Eye height 1.4 times width of face, eye glabrous in dorsal view. Temple not strongly receding behind eye. Stemmaticum with round edges, posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus to eye=2.0:1.0:3.0.

Mesosoma: Almost entirely setose ( Figs 3 d, 14d), 1.4 times longer than maximally high. Pronotum smooth laterally. Mesoscutum setose. Notauli weakly but distinctly impressed on anterior 0.85 of mesoscutum. Mesopleural sulcus absent. Scutellar sulcus narrow and finely crenulate. Propodeum coriaceous with sparsely distributed long setae.

Wings: Fore wing ( Figs 3 f, 14e). Ratio of length of veins SR1:3-SR:r=3.57:2.2:1.0. Ratio of length of veins 2- SR:3-SR:r-m=1.4:2.0:1.0. Veins 2-M & 3-SR, 3.00 times & 2.00 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 distinctly curving towards anterior wing margin. Ratio of length of veins 1- M:m-cu=2.0:1.0. Vein 3-CU1 curved posteriorly. Hind wing. Evenly setose. Vein SC+R1 2.25 times length of 1rm.Vein 1r-m 1.3 times length of R1.

Legs: Claw simple. Ratio of length of hind femur:tibia:basitarsus=2.1:2.5:1.0. Hind femur (excluding trochantellus) 3.6 times longer than maximally deep, broadest at middle, rather flattened laterally, sparsely setose. Hind tibia entirely setose. Hind basitarsus 2.75 times longer than maximally deep. Outer hind tibial spur reaching approximately 0.41 of distance along basitarsus.

Metasoma: Sparsely setose and foveolate ( Figs 4 a, 14f). First tergite sparsely setose, weakly crenulated. Second tergite entirely setose, finely and weakly crenulated 1.5 times longer medially than third. Second and third tergites transverse dorsally, second tergite 1.64 times and third tergite 3 times as wide apically as long medially. Second metasomal suture narrow. Third tergite sparsely setose, crenulated. Fourth and fifth tergites sparsely setose, crenulated. Hypopygium large and protruding beyond apex of tergites. Ovipositor sheath 0.78 mm. long.

Coloration: Head mostly black with yellow brown spot on face below antenna base. Mesosoma black. Wings almost clear, venation and pterostigma brownish. Fore leg yellow brown, mid leg yellow brown with coax black, hind leg black with apical half of femur and basal 1/5 tibiae yellow brown. Metasoma mostly yellow brown with slight black lateral marking on 3–5. Sternites with yellow brown markings. In male all legs entirely black, apical half third metasomal tergite black, sixth tergite black.

Etymology: From Latin cohaerere meaning to be consistent.

Material examined: Holotype: female, Angola, L.S. Jao Sul, (18 miles east), 26–27.ii.1972, P. Alexandre, BMNH.
