leg.: F. Koch (MNHU). 1 female: Zimbabwe: Salisbury [Harare] Chishawasha iii.1981. A. Watsham (BMNH); 1 female: same data as previous specimen, except: v.1981 (BMNH).
Diagnosis
.
Head mostly black, mesosoma mostly yellowish orange, metasoma testaceous; antenna with a pale median ring; most of microsculpture densely punctate to
punctate-reticulate
but mesoscutum transversely striate; clypeus
apico-laterally
bluntly pointed; hypostomal carina joining occipital carina shortly but distinctly above mandibular base; propodeum without carination; gastrocoelus and thyridium deep,
inter-thyridiae
interval narrow. HdWi 1.7; HfWi 1.1; Ci 1.6; Mi 0.8; IOi 1.5; OOi 1.5; Fli15.8; Fli151.3; Fli301.0; OTi 0.3. Male unknown.
Description
.
FEMALE (4 specimens). B 7.5-7.6; A 5.5-5.7; F 4.7-4.9 (Holotype B 7.6; A 5.6; F 4.8).
Color
. Head black with lower face and clypeus tending to dark red, mouthparts dark yellowish, scape and pedicel pale yellow, flagellum fuscous with basal flagellomeres lighter and flagellomeres 7-10 white; mesosoma
yellowish-orange
with mesoscutum somewhat darker and dorsal margin of pronotum yellow; legs
yellowish-orange
with all trochanters, fore and middle coxae pale yellow; wings hyaline, venation light brown; metasomal tergites testaceous with median black maculae of variable extent on tergites 3-5.
Head. Hemispherical, entirely densely and coarsely punctate to
puncto-striate
; mandible regularly tapered toward apex; malar line moderately long; clypeus triangular, its apical margin convex with two strong blunt teeth
apico-laterally
; face slightly transverse with a very weak median tubercle between toruli; ocellar triangle distinctly wider than high; temple long, regularly rounded behind eyes; hypostomal carina joining occipital carina distinctly above mandibular base; antenna hardly enlarged
medio-apically
, with 30-31 flagellomeres.
Mesosoma. Shining; pronotum rugulose, epomia weak; mesopleuron and metapleuron densely
punctate-reticulate
but speculum smooth; sternaulus moderate, reaching
mid-length
of mesopleuron; epicnemial carina ventrally moderately raised, slightly kinked
medio-ventrally
; postpectal carina interrupted in front of mid coxae; mesonotum transversely striate; notaulus anteriorly moderate, posteriorly obsolete; scutellum weakly convex, carinate to apical quarter; propodeum without carination, transversely
aciculo-rugose
, sculpture anteriorly weaker. Wings. Hind wing with distal abscissa of Cu1 joining 1/Cu&
cu-a
below its middle.
Metasoma. All tergites
punctate-reticulate
; tergite 1 moderately slender, regularly widened to apex; gastrocoelus within basal 1/5, wide and deep, thyridium transverse,
inter-thyridiae
interval very narrow; ovipositor straight.
MALE. Unknown.
Etymology.
