Material examined. Holotype. TANZANIA: female, Mkomazi Game Reserve , Ibaya Hill 03 58 S, 37 47 E, 27.xi– 10.xii.1995, Malaise Trap, Montane forest, leg. S. Van Noort (deposited in: SAMC).

Diagnosis. Xorides simoni sp. n. is characterized by the combination of the following characters: body generally red-brownish; vertex smooth, almost impunctate; antenna subapically not sharply angled at a single joint, first flagellomere short, about 0.6× length of the second flagellomere; face rugulose; pronotum densely punctate, smooth ventrally, with foveolate ridge; epomia strong, angled at the upper proximal end of pronotum; collar with two longitudinal carinae; epicnemial carina absent; propodeum with longitudinal and transverse carinae distinct and strong, tooth-like projections strong; with traces of carinae, tooth-like projections strong; fore and middle trochantelli without apical tooth; fore wing with vein cu-a basad of Rs&M by about 0.2 of its length; first metasomal tergite 2.5× as long as apical width, rugulose laterally, longitudinally wrinkled centrally, with transverse grooves, lateral longitudinal carinae present, almost reaching the apex of tergite; ovipositor about 2.4× length of hind tibia.

Description. Female. Holotype (Fig. 11). Body length approximately 11.0 mm. Fore wing 7.0 mm.

Head (Figs 11B, 11D, 11E, 11F) depressed, temples short and parallel behind eyes, covered with white setae; frons minutely punctate, with long carina-like projection between antennal sockets; length of the ocellar-ocular distance 1.1× maximum diameter of lateral ocellus; ocelli small, hind ocellus on line with eye; temples transversely wrinkled; vertex smooth, almost impunctate; occipital carina complete, somewhat emarginated dorsally; antenna with 21 flagellomeres, subapically not sharply angled, first flagellomere about 0.6× length of the second flagel-

Mesosoma (Figs 11D, 11E, 11G) densely pubescent; propleuron wrinkled dorsally, densely punctate ventrally; pronotum swollen apically, densely punctate, smooth ventrally, with foveolate ridge, epomia strong, angled at the upper proximal end of pronotum; collar with two longitudinal carinae; mesoscutum elongate, densely punctate an- teriorly and laterally, transversely wrinkled posteriorly, with strong notauli; scutellum and postscutellum sparsely punctate; postscutellum bounded by strong carinae; mesopleuron densely punctate anteroventrally, epicnemial carina absent; sternaulus indistinct; metapleuron rugose; propodeum rugulo-punctate, with longitudinal and transverse carinae distinct and strong, tooth-like projections strong; pleural carina distinct, but weak, submetapleural carinae strong, but indistinct posteriorly; spiracles round and moved to anterior edge of metapleuron.

Legs slender, hind femur 4.0× as long as wide, hind coxa sparsely punctate, fore and middle tibiae not swollen, narrower than femora; with V-shaped median ventral groove and subapical emargination; fore and middle trochantelli without apical tooth; hind tibia with strong spines; tarsal claws simple.

Wings. Fore wing with vein 2 rs-m long, 2.5× distance between 2 rs-m and 2 m-cu; vein cu-a basad of Rs&M by about 0.2 of its length; hind wing with distance between distal abscissa of Cu 1 and M about 1.5× the vein cu-a length.

Metasoma (Figs 11C, 11H) densely pubescent; first tergite 2.5× as long as apical width, rugulose laterally, longitudinally wrinkled centrally, with transverse grooves, lateral longitudinal carinae present, almost reaching the apex of tergite; second tergite 1.0× as long as apical width, longitudinally wrinkled, with two large basolateral swellings and central triangular swelling behind them, delimited by grooves; third tergite 0.7× as long as apical width, the same sculpture as previous tergite, with only basolateral swellings distinct; the remaining tergites smooth proximally, densely pubescent distally; ovipositor about 2.4× as long as hind tibia, with the apical teeth; ovipositor sheaths densely pubescent.

Colour. Body generally red with black marks, except face laterally and centrally, temples centrally, flagellomeres 9–15, pronotum ventrally, metasomal tergites apically (except the first), fore and middle legs partly yellow; pterostigma brown, yellow basally; ovipositor sheaths and three vertical stripes on fore wing brown.

Male. Unknown.

Distribution. Tanzania.

Etymology. This species is named after collector of the specimen, Simon Van Noort.
