( Figure 73 View Figure 73 )
Metopina tanjae Disney and Prescher, 2003 View in CoL .
The hitherto unknown male is described below.
Male
Head similar to female except palps are broader and with only three long bristles at tip, the labrum is pale straw yellow and clearly not as broad as diameter of postpedicel, and labella with fine hairs instead of strong teeth on their inner faces. Thorax similar to female. Abdomen with brown tergites and venter. The latter with sternum of fourth segment with a patch of hairs, each of which has its basal socket surrounded by disc of pigment, but these discs do not coalesce to form a distinct sternite. Hypopygium, including anal tube, brown. Legs similar to female except base of hind femur and trochanter as Figure 73B View Figure 73 . Wing 0.8 mm long and with basal region as Figure 73A View Figure 73 , otherwise it and haltere similar to female.
Recognition
The males of most Western Palaearctic species have a, typically pale, modified spine near the tip of the lower margin of the hind trochanter (e.g. Figure 71C View Figure 71 ). There is no such spine in M. tanjae , M. crassinervis Schmitz , M. galeata (Haliday) and M. ulrichi Disney. While M. trochanteralis Schmitz also lacks such a spine its trochanter has two rows of thick tooth-like spinules along the length of the ventral edge instead. Metopina crassinervis has the entire costa conspicuosly thickened. The hind femur of M. ulrichi has a distinctive patch of subparallel furrows on the posterior face. Hence the male of M. galeata most closely resembles M. tanjae , but it has much darker veins 4–6 and, like M. heselhausi ( Figure 71A View Figure 71 ), the costa being only slightly thickened at its junction with vein 1. In M. tanjae the costa is clearly thickest before its junction with vein 1 ( Figure 73A View Figure 73 ).
