Fig. 9 View FIGURE 9

Description, holotype Ƌ. Body length 3.5 mm. Forewing length 2.6 mm.

Colour. Black, except distal area of mandible, palpi and tarsi dark castaneous; wings hyaline, veins castaneous.

Head. Mandible 0.46 × LH, distinctly wider distally, distal teeth large. Clypeus with well-projected trapezoidal median lobe, its surface subvertical, median area elevated but forming carina, apical margin slightly incurved in dorsal view, and triangular in frontal view, lower border incurved in frontal view, lateral lobe short. Antennal foramina distant each other about 1.24 × antennal foramen diameter. First four antennomeres in ratio 31:8:30:30. Antenna reaching metasomal tergite II, pedicel slightly wider than long, flagellomeres almost three times longer than wide; flagellar pubescence dense, short and subappressed with some sub-erect outstanding setae; sensilla pale, elongate, dense, aligned in longitudinal series of about 6 in each flagellomere. Eye suboval, mid-sized, placed at middle-dorsal area of head in lateral view, with sparse and mid-sized setae. Frons strongly coriaceous, punctures very inconspicuous, frontal line as polished impression, of median length. LH 1.01 × WH. WF 0.58 × WH. WF 1.38 × HE. OOL 1.55 × WOT. VOL 0.94 × HE. Distance of posterior ocellus to vertex crest 1.2 × DAO. Distance of anterior ocellus to supra-ocular line 1.07 × DAO. Frontal angle of ocellar triangle acute; ocellar triangle not compact, POL 1.44 × DAO. Vertex and sides of head posterior to eye broadly rounded. Occipital carina complete, visible in full dorsal view. Malar space 0.42 × as long as wide. Hypostomal carina straight, angled medially, progressively thickening mesad.

Mesosoma. Mesothorax strongly coriaceous as frons. Dorsal pronotal area subtrapezoidal, wider than long; anterior discal margin not outlined. Mesonotum divided into anteromesoscutum and mesoscutellar-axillary complex, clearly separated by transscutal fissure. Anteromesoscutum shorter than about mesoscutellum, notauli absent, parapsidal signal incomplete anteriorly. Mesoscutum-mesoscutellar suture conspicuous, deep, anterior margin almost straight, posterior margin curved and notched medially, lateral end conspicuously dilated and blunt. Metapectal-propodeal disc strongly areolate, with very few setae, surface flat centrally and convex peripherally, median length 1.05 × median width, metapostnotal median carina incomplete, occupying only anterior half of disc; metapostnotal-propodeal and paraspiracular carinae absent; lateral carina present and conspicuous; transverse posterior carina complete; spiracle small, elliptical, placed at lateral carina. Propodeal declivity areolate, surface subvertical and almost flat, median carina absent. Lateral surface of metapectal-propodeal complex strongly areolate. Prosternum median-sized and depressed but flat. Mesopleuron with mesepimeron and mesepisternum completely separated by mesopleural suture, mesopleural pit large and shallow. Forewing with two closed cells, costal vein absent. Claws curved, simple.

Metasoma. Coriaceous, tergite II 1.88 × as long as tergite III, with pair of subcircular, excavated, light anterolateral spots. Hypopygium triangular, posterior margin angularly produced. Genitalia: small, about 485 µm long, paramere double, dorsal arm sub-diamond-shaped, ventral arm badly progressively widening apicad, apex rounded. Cuspis bifid, ventral arm short, apex rounded, dorsal arm long, wide, apex blunt. Aedeagus subbottleshaped, basal portion only slightly dilated, apical portion thick and progressively narrowing apicad, progressively filamentous and little sclerotized apicad, apex curved outward, surpassing slightly paramere apex height; apodeme not dilated basally, not surpassing genital ring; dorsal half of genital ring much more advanced basad than ventral half.

Variation. Head longer; sensilla aligned in longitudinal series of 8 in each flagellomere; vertex less convex; metapostnotal median carina complete or failed posteriorly; spots of metasomal tergite II elliptical. Material examined. Holotype ♂, S. Africa, W. Cape, Avondale farm, AC2, 32°16.50”S 22°56.61”E, 22–29 Apr 2001, HG Robertson & R Tourle, Nama Karoo on calcrete, pit fall, BW01-AC2-P05 ( SAM-HYM-A027210 ) GoogleMaps . Paratypes. S. Africa, W. Cape: 1♂, Elandsfontein farm, Site E 4, 32°17.69”S 23°00.57”E, 21 Apr 2001, S van Noort & HG Robertson, Nama Karoo on dolorite soils, Malaise trap, BW01-A1-M10 ( SAM-HYM-A027211 ) GoogleMaps ; 1♂, Lammerskraal , Prince Albert Distr. C.P. ( SAM-HYM-P013769 ) .

Diagnosis. This species is similar to G. banzi sp. nov. (see its Diagnosis).

Etymology. The specific epithet bubanzi is an adjective from IsiXhosa, which means wide, in allusion to the very wide head.
