Description of male. Head. Ground-colour black. Distance between eye margins at upper part of frons 0.10 mm (about 2x width of anterior ocellus). Frontal vita linear (almost absent) in dorsal half of frons, about 0.15 mm wide ventrally, black in dorsal view and lighter in ventral view, without setulae. Both fronto-orbital plate and parafacial silvery in dorsal view and almost black in ventral view. Fronto-orbital plate approx. 0.05 mm wide dorsally and 0.10 mm ventrally, 6–7 frontal setae without interstitials. Parafacial at upper part 0.10 mmm wide, ventrally approx. 0.08 mm wide (in middle about 2/3 as wide as first flagellomere). Face and gena grey. Eye without ommatrichia. Occiput black, postocular setulae short, uniserial and nearly uniformly long in dorsal part. Antennae black, flagellomere 2x as long as broad. Arista black, basally thickened, microscopically pubescent. Proboscis short, theca of proboscis thinly dusted, clypeus microtrichose. Palpus black, narrow, subequally long as proboscis. Thorax. Black, uniformly rather light bluish-grey microtrichose from all points of view including pleura, without vitae. Presutural acrostichals biserial, postsutural triserial. Setae distinguishable from setulae: 2 postpronotal, 1 seta remarkably close to inner margin of Postpronotum, 1 presutural supraalar, 2 postsutural intraalars, 1 postsutural supraalar. Two prealar setae, anterior one half as long as posterior notopleural, 2 postalars. Notopleuron with two setae and without setulae. Proepisternal depression bare. Both proepisternum and proepimeron with 1 long and 1 shorter seta. Wings very slightly darkened with brownish-yellow veins. Calyptrae white, lower one distinctly projecting beyond upper one. Halter yellow. Legs. Legs blackish-brown, knees of fore legs only very indistinctly paler. Coxa without modified setae. Fore femur with 3 rows of posteroventral, posterior and posterodorsal setae. Fore tibia without setae except preapicals. Mid femur strongly narrowed in apical 1/5, with a row of anteroventrals subequally long as femur depth, abruptly denser and shorter just before apical narrowed part; posteroventral setae in a single row basally, in apical part in two rows, and a single regular row of posterior setae, all slightly longer than femur depth. Mid tibia slightly ventrally compressed in basal third, the ventral mat of soft pubescence about as long as tibia depth on apical half and shorter on basal half, 0–1 anterodorsal and 1 posterodorsal seta. Mid basal tarsomere with distinct basal ventral crest. Hind coxa without setae on posterior inner margin. Hind femur distinctly swollen in apical third, this swollen part contains more than 10 long and irregularly arranged anteroventrals (absent on basal part of femur); with a complete row of posteroventrals turning ventrally on swollen part and merging with anteroventrals. Hind tibia with 1 long submedian dorsal seta, 1 anterodorsal and 1 anteroventral seta, both inserted slightly below dorsal seta and with several short and fine posteroventrals. Abdomen. Ground-colour brownish-black. Densely light grey dusted; segments 2 to 4 with narrow dark midline, lateral parts of tergites without darkening. Terminalia . As in Figs 4–5 . Cercal plate well fused, narrow dorsally and broader ventrally, and tapered at tip; surstylus very broad basally; bacilliform sclerite corkscrew-shaped. Measurements. Length of wing, 3.9– 4.1 mm. Length of body, 4.6 mm.

Distribution: Czech Republic and Slovakia.

Remarks. Fannia bohemica sp. nov. belongs to F. postica group. In the recent key ( Barták et al. 2016) this species leads to couplet 20 but differs from all species arranged here by the apically swollen hind femur with more than 10 anteroventrals. Genitalia (except cercal plate) are remarkably similar to the recently described F. latistylata Wang, 2007 . However, the latter species differs by presence of posterodorsal setae on hind coxa, lacking crest on mid basal tarsomere, 13–14 frontal setae, 1 supraalar, and brown calyptra and wing.
