Allocladius bubatus sp. n.

( Fig. 23 )

Pseudosmittia rectilobus Harrison 1992:187 , pro parte, not Freeman

Type material: Holotype male, ETHIOPIA: Addis Ababa, swarming over lawn, ix. 1983, A. D. Harrison ( ZMBN Type No. 428).

Diagnostic characters: The very well developed tongue-shaped superior volsella, together with the absence of an accessory lobe of the inferior volsella distinguish the male imago from other members of the group.

Etymology: From the Middle Latin (and Greek) bubo, a tumor, a swelling in the groin, and the Latin -atus, suffix meaning provided with, referring to the large superior volsella.
