Type material examined

Holotype

Female

Pedicel plus flagellum about 2.7× as long as scape, gaster about 4.0 × as long as wide, syntergum at least 6.6 × as long as wide (Fig. 17C, E); CC asetose.

Biology

Unknown.

Distribution

Sierra Leone (Gumovsky, 1997).

Remarks

This species is so far only known from the holotype; there are some male specimens from other Afrotropical areas which may or may not be conspecific; however, this is difficult to infer solely from the morphology. The female of X. halli comb. nov. differs from those of the similar species X. kayovei and X. neserorum sp. nov. in having a shorter gaster and shorter antennal segments, and also in the asetose costal cell of the fore wing.
