Taxon classification Animalia Hymenoptera Figitidae
Xyalaspis Hartig, 1843
Remarks.
Not common in the Afrotropical region. The genus is often difficult to separate from
Aegilips
and requires revision.
Diagnosis
.
Xyalaspis
are often easy to recognise by their very distinct scutellar spines, but several taxa have more blunt or moderate spines that are close to character states found in
Aegilips
. In these cases, the scutellum of
Xyalaspis
is characterised by a heavier foveolate sculpture, where no circumscutellar carina is obvious. As currently circumscribed, the genus is somewhat heterogenous in the Afrotropical region, and a distinct species group is characterised by a strongly sculptured mesoscutum with longitudinal carinae as well as strong genal carinae.

Distribution
.
Mainly Holarctic, but also present throughout the Old World Tropics. Afrotropical records: South Africa (
Kieffer 1912
), Nigeria, Uganda (
Mata-Casanova et al. 2014
), Cameroon, Democratic Republic of Congo, Madagascar, Malawi, Yemen, Zimbabwe (here).
Biology.
Parasitoids of aphidivorous
Neuroptera
larvae (

,

).
Species
richness.
Xyalaspis capensis
(Kieffer, 1912), comb. n. (
Aegilips
) (South Africa, Zimbabwe) (Type supposedly in ZMBH, but not found there. However, the original description has been deemed sufficient for generic placement here)
Xyalaspis subsaharica
Mata-Casanova & Pujade-Villar, 2014 (Nigeria, Uganda)
Several undescribed species from elsewhere in the region.
