Diagnosis

Large; head and mesosoma mostly yellow, metasoma mostly reddish-testaceous; face densely and shallowly punctate; inner margins of eyes barely diverging ventrally; clypeus transverse and mostly smooth; malar line long; remainder of head coriaceous; antenna long with 38 flagellomeres, penultimate flagellomere quadrate; mesosoma densely punctate to punctate-granulate except most of pronotum finely and sparsely punctate, ventral half of speculum smooth, and propodeum roughly transversely rugose medially; female femoral tooth long and narrow; ovipositor moderately long, apically strongly sinuous. Male with antenna shorter, with 33 flagellomeres, inner margins of eyes more diverging ventrally, ocelli enlarged, mesoscutum coriaceous, hind femur stouter and femoral tooth stronger.

Differential diagnosis

Large yellow to reddish-testaceous species, differentiated from all other Afrotropical species by the combination of the strong and narrow femoral tooth in the female, the blunt transverse rugosities on the propodeum, the long malar line, the long antenna and the extensively punctate mesonotum.

Type material

Holotype

SOUTH AFRICA: ♀, “ SOUTH AFRICA, 35–70 km W Pretoria Magaliesberg 31-xii–1994 A. Freidberg ” ( SANC).

Paratype

SOUTH AFRICA: ♂, same label data ( SANC).

Description

Female (holotype)

B 11.9; A 6.1; F 6.2; CT 1.8; ML 0.7; POL 0.7; OOL 1.4; Fl n-1 1.0; ASM 2.3; OT 1.8; FFT 2.

COLOUR. Head and mesosoma mostly yellow with frons and mesoscutum barely darker, and propodeum fading to reddish-testaceous; metasoma mostly reddish-testaceous; legs yellow; ovipositor sheath and flagellum dark brown; wings hyaline, venation yellowish.

HEAD. Face very densely and shallowly punctate; inner margins of eyes slightly diverging ventrally; clypeus transverse, long, mostly smooth with some punctures along dorsal margin; malar line long; vertex and temple coriaceous; ocelli relatively small; occipital carina joining hypostomal carina above mandible base; antenna long with 38 flagellomeres, penultimate flagellomere quadrate.

MESOSOMA. Mesosoma moderately elongate; pronotum sparsely and finely punctate with anterior margin shallowly crenulate; mesopleuron and metapleuron densely punctate with a striate oblique furrow below speculum, speculum ventrally smooth; mesoscutum densely punctate-granulate, punctures confluent into fine transverse rugosities along notaulus; notaulus moderate; scutellum densely punctate; propodeum roughly and densely punctate, punctures confluent into blunt transverse rugosities medially, area superomedia long. Legs. Female femoral tooth long and narrow.

METASOMA. Tergite 2 and apex of tergite 1 aciculate, following tergites coriaceous; thyridium long elliptic, its main axis longitudinal; ovipositor moderately long, apically moderately sinuous.

Male (paratype)

B 11.2; A 5.8; F 6.3; POL 0.9; OOL 0.9. Inner margins of eyes more strongly diverging ventrally; antenna with 33 flagellomeres; ocelli enlarged; mesoscutum more shallowly sculptured, mostly coriaceous with punctures along rugose notaulus; hind femur and femoral tooth stouter; propodeum and metasoma barely lighter; otherwise similar to female.

Distribution

South Africa.
