Pristomerus yoccolo   sp. nov.

Fig. 47 View Fig


Moderately sized; yellowish orange overall; face moderately punctate; clypeus transverse and almost smooth; inner margins of eyes subparallel; malar line moderately short; upper head finely coriaceous; antenna with 30 flagellomeres, penultimate one slightly shorter than wide; mesosoma moderately to densely punctate but pronotum quite smooth and speculum hardly sculptured; female femoral tooth long and unusually narrow; tergite 2, apical half of tergite 1 and base of tergite 3 longitudinally aciculate; ovipositor long and straight, barely sinuous apically. Male unknown.

Differential diagnosis

Moderately sized and yellowish-orange overall; differentiated from most other Afrotropical species by the long and basally noticeably narrow female femoral tooth. Such a narrowed tooth is only otherwise found in P. afrikaner   sp. nov. and P. yakoma   sp. nov. The former, from South Africa, has, however, a longer malar line and longer antennae, and the latter has a coriaceous to smooth mesonotum. Pristomerus yoccolo   sp. nov. is otherwise somewhat similar to P. babinga   sp. nov., whose femoral tooth is distinctly stouter and in which the clypeus is more transverse and the inner orbits diverge ventrally.

Type material


IVORY COAST: ♀, “Côte d’Ivoire: Aman Ikro 50 km. N. W. Abengourou J. Decelle II.1963 ” ( MRAC).



Female (holotype)

B 6.3; A 4.8; F 4.3; CT 1.9; ML 0.5; POL 0.9; OOL 1.1; Fl n-1 0.9; ASM 2.1; OT 1.9; FFT 2.

COLOUR. Yellowish-orange overall, head and mesosoma barely darker dorsally, with basal infuscate markings on tergites 2 and 3; flagellum and ovipositor sheath dark brown; wings hyaline, venation brown.

HEAD. Face moderately punctate, weakly bulging mid-longitudinally; inner margins of eyes subparallel; clypeus transverse and long, almost smooth; malar line moderately short; frons, vertex and temple finely coriaceous; occipital carina joining ventrally hypostomal carina shortly above mandible base; antenna with 30 flagellomeres, penultimate flagellomere slightly shorter than wide.

MESOSOMA. Moderately elongate; pronotum quite smooth; mesopleuron and metapleuron moderately densely punctate with a shallowly striate oblique furrow below speculum, speculum hardly sculptured; mesoscutum densely punctate-granulate, punctures confluent along notaulus into fine transverse rugosities; scutellum punctate; propodeum densely punctate-granulate, area superomedia moderately elongate. Legs. Femoral tooth long, narrow and acute.

METASOMA. Tergite 2, apical half of tergite 1 and base of tergite 3 longitudinally aciculate; thyridium subelliptic, its main axis longitudinal; ovipositor long and straight, barely sinuous apically.
