Xorides rufofacialis Varga   , sp. n.

( Fig. 10 View FIGURE 10 )

Material examined. Holotype. SOUTH AFRICA: female, Mossel Bay , Cape Province, iv. 1921, leg. R. E. Turner (deposited in: BMNH).  

Diagnosis. Xorides rufofacialis   sp. n. is characterized by the combination of the following characters: body generally red-brownish; vertex sparsely punctate; antenna subapically not sharply angled at a single joint, first flagellomere short, about 0.5× length of the second flagellomere; face reticulate rugose; pronotum densely punctate; epomia present; epicnemial carina absent; propodeum 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 0.3 of its length; first metasomal tergite 1.4× as long as apical width, densely punctate, with transverse grooves, carinae absent; ovipositor about 1.8× length of hind tibia.

Description. Female. Holotype ( Fig. 10 View FIGURE 10 ). Body length approximately 6.0 mm. Fore wing 4.5 mm.

Head ( Figs 10A, 10C, 10E, 10G View FIGURE 10 ) depressed, temples short and weakly rounded behind eyes, covered with long white setae; frons rugulose, with short carina-like projection between antennal sockets; length of the ocellar-ocular distance 1.4× maximum diameter of lateral ocellus; ocelli small, hind ocellus not extended behind eye; temples wrinkled; vertex sparsely punctate; occipital carina complete; antenna subapically not sharply angled, with 22 flagellomeres, first flagellomere about 0.5× length of the second flagellomere, flagellomeres 17–18 with four long sensillae; face about 0.5× as long as wide, reticulate rugose, tentorial pits deep; malar space 1.3× basal width of mandible, with strongly depressed subocular groove; clypeus 0.7× as long as wide, smooth, rounded apically.

Mesosoma ( Figs 10C, 10D, 10I, 10F View FIGURE 10 ) densely pubescent; propleuron sparsely punctate dorsally, wrinkled ventrally; pronotum swollen apically, densely punctate, epomia present; mesoscutum elongate, densely punctate, with weak notauli; scutellum and postscutellum densely punctate; mesopleuron densely punctate except posteriorly; epicnemial carina absent; sternaulus distinct on distal 0.2 of mesopleuron; metapleuron swollen, densely punctate; propodeum densely punctate, with traces of carinae, tooth-like projections strong; pleural and submetapleural carinae present; spiracles elongate, small.

Legs slender, hind femur 3.0× 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 trochanters without apical tooth; hind tibia with strong spines; tarsal claws simple.

Wings. Fore wing with vein 2 rs-m short, 0.2× istance between 2 rs-m and 2 m-cu; vein cu-a basad of Rs&M by about 0.25 of its length; hind wing with distance between distal abscissa of Cu 1 and M about as long as vein cu-a.

Metasoma ( Figs 10D View FIGURE 10 ) sparsely punctate; first tergite 1.4× as long as apical width, densely punctate, with transverse grooves, carinae absent; second tergite 0.7× as long as apical width, densely punctate, with two basolateral and third central triangular swellings delimited by basolateral and subapical transverse grooves; third tergite 0.6× as long as apical width, with two swellings, sparsely punctate proximally, granulate distally; the remaining tergites indistinctly sculptured; ovipositor about 1.8× length of hind tibia, with the apical teeth; ovipositor sheaths densely pubescent.

Colour. Body generally red-brownish with black marks except flagellomeres 11–14, tergites 1 and 7 apically, ovipositor sheaths subapically, and pterostigma basally yellow; fore wing with tree brown stripes.

Male. Unknown.

Distribution. South Africa.

Etymology. This species is named after the entirely red face.
