 1920. Vidensk. Meddel, fra Dansk naturh. Foren. 71, 31, 36 (setifer). 



Male. Frons considerably broader than high, greyish black, dull; 

 inner bristle of lower row a little below the outer and about equally 

 distant from it and from the upper supraantennal ; supraantennal 

 bristles unequal, the lower pair quite small ; the upper supraantennals 

 as distant as the inner bristles of middle row, the lower only slightly 

 more approximate. Antennæ somewhat large, black, arista distinctly 

 pubescent. Palpi well developed, a little above ordinary size, brownish; 

 they have a long bristle at the end, the others seem to be weaker. 

 Thorax black, slightly shining, with brownish pubescence. Mesopleura 

 bare. Abdomen black, dull; it is long, slender and tapering; the short, 

 sparse hairs slightly longer at the hind margins of the segments, 

 longest on sixth segment. Hypopygium large, longer than sixth 

 segment, somewhat cylindrical; it is dark brown, somewhat greyish, 

 with numerous short hairs on the hinder part downwards on the 

 sides, but no bristles; ventral plate large, brownish, rounded at the 

 end; anal tube short, brownish. Legs yellowish brown, hind femora 

 slightly darker above and towards apex; front tibiæ with a postero- 

 dorsal row of rather long, but fine, erect bristles; hind femora with 

 somewhat dense, longish hairs below the basal half; bristles on hind 

 tibiæ numerous, small and hair-like. Wings somewhat brownish 

 tinged; veins strong, dark brown; costa reaching well beyond the 

 middle, costal divisions about as 11 — 10 — 5, thus 1 and 2 nearly 

 equal and each double 3; costal cilia long; fork longish, angle somewhat 

 large; fourth vein considerably curved in its basal part. Halteres 

 black. 



Female. Unknown. 



Length 1,7 mm. 



This species is evidently related to discreta and especially to 

 nudiventris, but it is at once distinguished by the row of bristles on 

 front tibiæ and the hypopygium. 



A. setifera is very rare, only one specimen has been taken, Holte 

 "Ve 1917 (Th. Mortensen).
