Pristomerus kelikely
Rousse, Villemant & Seyrig, 2013
Fig. 14
Diagnosis
(updated from
Rousse
et al.
2013
)
Small; yellow to yellowish-orange overall; face moderately to densely punctate; inner margins of eyes slightly converging ventrally; clypeus strongly transverse, sparsely and shallowly punctate; malar line short; remainder of head coriaceous; occipital carina joining hypostomal carina at mandible base; antenna with 29–32 flagellomeres, penultimate flagellomere longer than wide; mesosoma elongate, moderately to densely punctate but pronotum almost entirely and ventral half of speculum smooth, and mesonotum apically shallowly punctate; female femoral tooth absent; ovipositor moderately long, apically weakly sinuous. B 3.2–4.6; A 2.8–4.0; F 3.2–4.3; CT 2.0; ML 0.4; POL 0.8; OOL 1.2; Fl
n–1
1.2
;
ASM
2.1; OT 1.6–1.8; FFT 0. Male with ocelli not enlarged, hind femur and femoral tooth stouter, and area superomedia sometimes more slender. POL 0.9; OOL 1.1.
Differential diagnosis
Small and entirely yellow to yellowish orange species; differentiated from most other Afrotropical species by the absence of the femoral tooth in females, the short malar line, the strongly transverse clypeus and the rather long ovipositor. It is closely related to
P. moramora
and
P. venda
sp. nov.
, from which it may be differentiated by the colour and antennal length characters given in the key (see comments below). It is also structurally very similar to
P. sara
sp. nov.
; however, this species exhibits white-marked femora and tibiae, a colour pattern that appears to have ecological relevance (see general discussion).

Comments
The three species
P. kelikely
,
P. moramora
and
P. venda
can only be keyed by rather weak though constant differentiating features.
Pristomerus moramora
is mostly separated from the other two by the extensive dark colouration of the mesosoma and metasoma. Furthermore, the males of
P. kelikely
and
P. moramora
have ocelli that are not enlarged, which is very unusual in
Pristomerus
and separate both from
P. venda
. However, several specimens in the SAMC and MNHN collections could not unambiguously be assigned to one of these three species: this species-complex needs further examination before being fully resolved.
