genitalia, lateral view. Scale bars: 0.2 mm for Figs 6–7 , 0.4 mm for Fig. 8

Description – Measurements in mm: body length 1.91 (holotype), 1.85–2.00 (paratypes), wing length 2.17 (holotype), 1.72–2.20 (paratypes), wing breadth 0.86, 0.715–0.86. Body shiny black with thin dark microtomentum, pleurae even more shiny.

First flagellomere black, scape and pedicel greyish yellow, translucent. Arista (holotype) 0.01 + 0.055 + 0.836 mm (!) long.

Wing transparent, veins pale yellow. Wing membrane microcilia rather long and evenly distributed. Costa continued to vein M. Anal vein strong. Intra-crossvein section of M 0.24 mm; terminal section of Cu not reaching wing margin, 0.20 mm. Alula large. Halteres wax-yellow.

Coxae, femora, fore tibia and tarsi black, thochanters, mid and hind tibiae and tarsi yellow (former ones may be light brown). No preapical setae on tibiae. Ventroapical seta of mid tibia only 0.065–0.07 mm long. Claws large, semicircularly curved.

Preabdominal segments short, tergites with a pair of longer setae on lateral edges, otherwise setosity sparse.

Male hypandrium an intricate structure: in addition to the more ventral H-shaped part, it has a more dorsal transverse sclerite (lath), which joins to the main part at conjointment with epandrium. Aedeagal apodeme placed between that dorsal part and the ventral H-shaped part ( Fig. 3 , 7 ). Ejaculatory apodeme close with the phallic complex ( Fig. 3 ), placed less cranial than apex of aedeagal apodeme.

Female tergite 6 (free part) 0.24 mm long, that of tergite 7 0.30 mm.
