Capellari, Renato S. & Grichanov, Igor Ya., 2012, Review of the Afrotropical genus Aphasmaphleps Grichanov (Diptera: Dolichopodidae), African Invertebrates 53 (1), pp. 35-35 : 42

Aphasmaphleps paulyi sp. n.

Figs 5, 10

Etymology: The species is named for Alain Pauly (Brussels, Belgium), who collected all known specimens of this species.

Diagnosis: Male. Antennal stylus with apical lamella. Distal stylomere of arista-like stylus about 7× as long as basal stylomere. Veins R 4+5 and M slightly diverging apically, M evanescent. IIt 1 with ventral and anterior rows of stiff hairs, IIt 2 shorter than IIIt 3.

Description:

Very similar to A. bandia in all respects including morphology of hypopygium, except for the following features. (All specimens are quite discolourated due to long-term storage in alcohol.)

Male.

Body length 2.0 mm (in alcohol). Antenna 1.5 mm. Wing 1.4 mm long, 0.6 mm wide. Head. Antenna ( Fig. 5 ): 10, 7, 15, 20, 102; stylus with apical lamella.

Wing. CuAx proportion 0.07.

Legs. It: 1.5, 1.0, 0.6, 0.6, 0.6. IIt: 3.6, 0.7, 1.4, 1.0, 0.7. IIIt: 2.3, 2.0, 1.5, 1.1, 0.9. IIt 1 ( Fig. 10 ) with somewhat weaker ventral and anterior hairs.

Female. Unknown.

Holotype: ♂ (in glycerol) MADAGASCAR: Tul [éar Province], Morondava [19°53'S 44°28'E], 50 km N, 13 xii.1991, A. Pauly, forêt, rivière de sale ( ISNB).

Paratypes: 3♂ (in alcohol), same data as holotype ( ISNB) .

Comments: A. paulyi sp. n. is similar to A. bandia , but can be distinguished from the latter by having the antennal stylus with apical lamella.
