Elaphropeza notatithorax Senior-White, 1922

Elaphropeza notatithorax Senior-White, 1922: 151 , pl. XIV, fig. 10 (antenna) (male)

Type material examined: Male holotype; CEYLON / Matale Dist., / Suduganga / 29.v.1919; Elaphropeza / notatithorax / Senior White / TYPE male; Holotype; BMNH (E) # 244883 ( BMNH).

Senior-White (1922) described this species from two males that are now deposited in the BMNH. We have examined the holotype only, which is highly destroyed; the remnants are in a plastic tube attached to the original pin. There are two fragments of the body. The first includes a larger part of the thorax with the head (postpedicel and style missing on both antennae) and one fore leg. The second comprises the posterior part of the thorax including the hypopleuron, pteropleuron, metapleuron, halteres and abdomen (a little damaged). The surviving structures quite agree with the original description. We could only mention that in this species the palpus is rather yellow and the fore tibia lacks prominent bristles (except subapicals). Nigel White ( BMNH) kindly checked the sex of the paratype specimen, that we have not examined, and confirmed that it is a male .

Distribution. Sri Lanka.

Remarks. The relationships of E. notatithorax are unclear beyond inclusion within the E. biuncinata group, but probably this species is closely related to several species of Elaphropeza sharing curved subapical bristles on the hind tibia. The main distinguishing features of E. notatithorax are indicated in the key.
