In the male A. calcarator, the eyes almost touch on the face (“linien formig” sensu Negrobov 1979). In the new species the eyes are distinctly separated in the male by a distance of nearly the width of the scape; in the female the distance is even wider than the scape. In A. calcarator, the postpedicel is a little longer than wide and the arista is 3.5 times as long as the postpedicel (Negrobov 1979: fig. 1573). In the new species, the postpedicel is longer, twice as long as wide, and the arista is 2.5 times as long as postpedicel. In A. calcarator, the ventral bristling of the fore femur has a different pattern, with the longest bristles in the apical ⅔, while in the new species the longest bristles of the posterior ventral row are in the basal half only. In A. calcarator, the fore tibia is as long as tarsomeres 1 and 2 together. In the new species, the fore tibia is relatively shorter, as long as tarsomere 1 only. In A. calcarator, tarsomere 1 of the fore leg is narrow and elongated and as long as tarsomeres 2, 3 and 4 together. In the new species, tarsomere 1 is shorter than the following three tarsomeres together. The wing in A. calcarator is dark brown tinged, while in the new species the wing is only greyish tinged. Sternite 4 in the male of A. calcarator seems to bear two short exterior appendages, while there are none in the new species. The male terminalia are different in both species ( A. calcarator in Negrobov 1979: fig. 1575 and Fig. 2 for the new species).</p><p>Aphrosylus salensis sp. nov. differs from A. lindbergi, the only other known species from Cape Verde, in that the postpedicel in A. lindbergi is three times as long as wide. The haltere is white and apparently there is no long spur on the fore tibia. In the new species the postpedicel is twice as long as wide. The haltere is black and there is a very long spur on the fore tibia in both sexes.</p><p>Key to male Afrotropical Aphrosylus</p><p>Modified from Rampini &amp; Munari (1987).</p><p>1.

It has a wide Old World tropical and subtropical distribution from the Cape Verde archipelago in the west, all across continental Afrotropical Africa; in the Palaearctic realm it is known from Israel and Egypt, recorded throughout the Oriental Realm from the islands in the Indian Ocean, India and Sri Lanka to Indonesia and the Philippines in the east (Grichanov 2018). Recently, we also recorded it from southern Thailand and Singapore (Grootaert, Van de Velde &amp; Samoh, unpublished). There, it consists of two well separated populations with a barcode difference of 2.8% (Grootaert, Samoh &amp; Meier, unpublished).</p><p>We generally found this species along temporary bodies of water such as small lagoons on the supralittoral zone of the beach or in sun-exposed rainwater drains.

The dorsal lobe has a broad tip with a small apical point (Fig. 8A) and the ventral lobe is generally set with long bristles.</p><p>Key to male Crossopalpus from Cape Verde</p><p>1.
