Description. Male. Eyes not touching, eye-bridge of four facet rows, frontoclypeus with almost horizontal oval patch of insertions of hairs connected with dorso-ventral stripe of irregularly arranged hair pits between dorsal blunt (cut) apices of eyes ( Figs. 1, 2 View Figs ). Minimum distance between eyes 2.5 times as wide as diameter of facets. Ratios of distance of tangential points of ends of eyes to minimum width of frons and to facet diameter 4.8: 1 and 12: 1, respectively. Frontal suture broadly V-shaped, with very small triangular cavity in upper part. Antenna with 16 antennomeres. Scape very long, slightly widened distad ( Fig. 10 View Figs ), four times as long as pedicel, the latter cask-shaped. Flagellomeres pitcher-shaped and asymmetrical, terminal flagellomere smaller, ovoid, with long excentric digitiform protuberance on top; a pair of ascoids as in Figs. 11, 12 View Figs . Length ratios of maxillary palpomeres 1.0: 1.2: 1.3: 1.5, palpomere 4 annulate ( Fig. 3 View Figs ). Terminal lobe of labium bulbous ( Fig. 1 View Figs ), with many sensory setae. Cibarium 1.7 times as long as epipharynx.

Thoracic sclerites as in Fig. 6 View Figs . Wings ( Figs. 4, 5 View Figs ) lancet-shaped, clear, 1.6-2.1 mm long (1.7 mm in holotype), wing membrane bare, radial and medial forks complete; the following veins or their parts strengthened: Sc, R 1 distally, R 2 +3 basally, R 2 , R 3 distally, R 4 on both ends, R 5 , M 1+2 basally, M 1 distally, M 2 (not near medial fork), M 3 distally, M 4, and Cu. Basal costal nodes distinct ( Fig. 5 View Figs ), Sc uninterrupted, bent slightly in one point ; M 3 basally with connection to M 4 but not to Cu. R 5 extending distally and reaching wing margin a little behind apex of wing. Veins r-r, r-m and m-m not developed. Medial wing angle 163° ( BCD). Wing indices AB: AC: AD = 3.8: 4.0: 4.3 ; BC: CD: BD = 1.0: 1.2: 2.2. Wing 2.7 times as long as wide. Haltere 3 times as long as wide ( Fig. 6 View Figs ). Length ratios of femora, tibiae and first tarsal segments: P 1 = 1.8: 2.2: 1.0; P 2 = 2: 2.8: 1.2; P 3 = 2: 3.2: 1.2. Fore claws as in Fig. 13 View Figs .

Basal apodeme of male genitalia straight and narrowed proximally to sharp end in dorsal view ( Figs. 7, 8 View Figs ), expanded in lateral view ( Fig. 16 View Figs ), and bifurcated distally.Aedeagal complex sack-shaped, with small lateral protuberances, inside with a pair of short harpoon-shaped sclerites, divergently luxated; furca developed ( Figs. 7, 8 View Figs , 15 View Figs ). Gonocoxite ( Figs. 8 View Figs , 14 View Figs ) cylindrical, rather long and straight. Gonostyle thick basally, gradually tapering to apex, almost 1.5 times as long as gonocoxite. Epandrium broad and short, with two small elliptic patches of separated hair areas and one large nearly circular opening distad ( Fig. 9 View Figs ). Sclerotized remainders of tergite and sternite 10 inside of epandrium almost quadrate. Hypandrium narrow ( Figs. 7, 8 View Figs ), bare, conspicuously widened in middle. Epiproct small, hemicircular, hypoproct large, broad basally, tongue-shaped, both parts haired, epiproctal hairs in comparison with hypoproctal ones longer and more widely spaced. Surstyli cylindrical, straight (dorsal and lateral views), almost 1.5 times as long as epandrium. Number of retinaculi 15.

Female unknown.

Variability. The harpoon-shaped sclerites of aedeagal complex vary in shape and size ( Figs. 17 View Figs a-d). Angle of the margin of the caudal sclerite to the inner side of aedeagal apodemal protuberance (luxation) 106-148°, difference in luxation of the left and right sclerite in the same specimen 4-27°.

Differential diagnosis. Parajungiella bohdanecensis sp. nov. is characterized by the combination of the following characters: sack of aedeagal complex with small lateral protuberances caudally and a pair of short harpoon-shaped, divergently luxated sclerites inside ( Figs. 7, 8 View Figs , 17 View Figs a-d). Parajungiella consors (Eaton, 1893) has the sack of aedeagal complex rather compact, without protuberances, and the harpoon-shaped sclerites inside are placed at a 180° angle to the aedeagal apodemal protuberance and without luxation ( Fig. 18 View Figs ).

Etymology. The species is named after the type locality, Lázně Bohdaneč in eastern Bohemia.

Bionomics. Unknown. Adults were collected in a lowland area (220 m a.s.l.) near a drain with shore vegetation and large swamps in an alder wood ( Fig. 52 View Fig ). Some specimens were collected in a coal-mining area in swampy biotopes at a foot of a dump with Alnus , Phragmites , Scirpus , and on inundated shores of a river (417 m a.s.l).

Distribution. Czech Republic, eastern and western Bohemia.

Comments on the generic classification. The systematic position of the genus Parajungiella and all nomenclatorial problems and intergeneric relationships in the Paramormiini were discussed in detail by JEŽEK (1983b, 1984, 1985a). Including the new species, the genus now comprises 10 species restricted to the Palaearctic Region.
