Entedon (Cederholmia) halli Gumovsky, 1997: 26 .

Diagnosis

As for the group and also: scape pale, pedicel and flagellum dark; head dorsally nearly 3.0 × as wide as long ( Fig. 17H ); interantennal space without a process; gena bulging; fore tibia pale brown with two dark stripes, mid and hind tibiae darkened similarly, both not more than on basal half; axillular projection bidentate; median propodeal strip broad and smooth ( Fig. 17H ).

Type material examined

Holotype

SIERRA LEONE • ♀; Karina distr., at Makeni-Kabala road; 11°57′ W, 9°17′ N; 28 Nov. 1993; L. Cederholm, R. Danielsson and R. Hall leg.; loc. 10; Lund University Sierra Leone Expedition 1993; MZLU.

Description

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.

Male

Unknown.

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.
