Platycheirus marokkanus Kassebeer, 1998

Distribution. Morocco and Portugal ( Kassebeer, 1998; van Eck, 2016). New to Spain.

Examined material. Spain: ♂ ( JSA), Albacete , Sierra de Alcaraz, Batán del Puerto, 38°34’ N 2°21’ W, 1200 m, 21-VI-2003, J. van Steenis ; 1 ♂ ( DDG), Granada , Almi- jara, Cortijo los Capotes, 36°52’44”N, 3°43’54”W, 1240- 1270 m, 11-VI-2003, D. Doczkal .

Remarks. This species ( Fig. 6) belongs to the Platycheirus albimanus sub-group and is most similar to P. laskai Nielsen, 1999 . In P. albimanus (Fabricius, 1781) , P. ciliatus Bigot, 1884 and P. muelleri Marcuzzi, 1941 the apex of the protibia and the first tarsomere of protarsus is much wider than in P. marokkanus , and in P. nigrofemoratus Kanervo, 1934 the first tarsomere of protarsus is clearly wider than the maximum width of the protibia. In P. laskai , P. marokkanus and P. nigrofemoratus the setae on the protibia are short, at most as long as medial width of protibia, while in the other species these setae are long, more than twice as long as medial width of protibia. The angle of approximation of the eyes in males is 90° in P. albimanus , P. laskai and P. nigrofemoratus ; about 100° in P. marokkanus ; and about 120° in P. ciliatus and P. muelleri . Two species each have one character not shared with any other species; P. laskai has only one long black seta on profemur, which is placed apically, all others have three setae placed baso-medially; P. ciliatus has the basal tuft of setae on profemur with slightly flattened apex, while in all others the apex of these setae is narrowly rounded. In P. muelleri the ventral surface of protarsus has characteristic black markings, while in P. marokkanus these markings are reduced and at most dark-brownish.

The male specimen from Albacete was collected on flowers of Thapsia villosa .
