Description. Male. Head almost circular from frontal view, vertex elevated, paired cornicula developed ( Figs 1, 3View FIGURES 1 – 7), club-shaped, as long as distance between both bases of first palpomere, insertions of postocular bristles on dorsal margins of eyes not enlarged ( Figs 1, 2View FIGURES 1 – 7). Eyes separated, narrowest upper part of frontoclypeus equals two facet diameters or a little more, eye bridge with 4 facet rows ( Figs 1, 2View FIGURES 1 – 7). Ratio of the distance of the apices of eyes (tangential points) to the minimum width of frons is approximately 6.6:1. Interocular frontal suture well sclerotized, U-shaped, doubled by parallel ligament, barely transparent, almost fused in the middle with frontal suture ( Fig. 2View FIGURES 1 – 7). Frontoclypeus ( Fig. 1View FIGURES 1 – 7) with conspicuous, three-lobed central scar patch with wide oblong base, medial irregularly narrow lobe inversely T-shaped, prolonged almost to the interocular suture ( Fig. 2View FIGURES 1 – 7), with limited and hardly pointed parallel lobes ( Fig 1View FIGURES 1 – 7).
Antennae ( Figs 4, 5View FIGURES 1 – 7, 8View FIGURES 8 – 13) with 14 flagellomeres and covered with microtrichiae. Scape prolonged, cylindrical, conspicuously widened distally (twice broader than the basis), 3.5 times longer than spherical pedicel. Flagellomeres amphora-shaped, asymmetrical, necks generally shorter than swollen basal parts. Flagellomere 14 with bulbose basal node, neck very short with ovoid apiculus. The sensory filaments (ascoids) digitate ( Fig. 8View FIGURES 8 – 13), conspicuously arcuate aside, as long as or a little longer than flagellomeres, paired.
Maxilla and palpus maxillaris ( Figs 6View FIGURES 1 – 7, 9View FIGURES 8 – 13): relative length ratios of palp segments 1.0:1.4:1.5:2.2, apical segment annulated. Maxilla 1.3 times shorter than first segment, mouthparts extend beyond ends of basal palpomere ( Fig. 1View FIGURES 1 – 7). For terminal lobes of the labium ( Fig. 10View FIGURES 8 – 13), lines of spines between both lobes not developed (compare with Fig. 24View FIGURES 21 – 26 of Jungiella syriaca ). Relative ratio of maximum length of cibarium to length of epipharynx 2:1 ( Fig. 7View FIGURES 1 – 7).
Thorax. Dorsal fold of circular thoracic spiracle and shape of thoracic sclerites including insertions of macrosetae as in Fig. 11View FIGURES 8 – 13. Length ratios of femora, tibiae and first tarsomeres: P1 1.7:2.1:1.0, P2 1.9:2.9:1.2 and P3 1.9:2.7:1.2, paired tarsal claws of P1 elongated and somewhat bent apically, setose in their basal part ( Fig. 13View FIGURES 8 – 13).
Wings ( Fig. 18View FIGURES 18 – 20) lancet-shaped, 1.9 mm long (paratypes 1.8–2.1 mm), not enlarged in anal and humeral regions, apically rounded, 3.4 times as long as its wide. Wing membrane translucent quite clear, without infuscation. Sc longer than basal cell, almost straight, somewhat thickened in the middle. R1 with long parallel barely sketched linear streak running from wing basis starting near Sc. Next strengthened veins: R1 distally (more than two thirds), R2+3 basally, R2, R4 only in basal cell, R5, M1+2 mainly in basal cell, CuA1 and CuA2 (the last conspicuously expanded in the origin). Radial fork is complete, medial fork sometimes slightly incomplete, tip of CuA2 always incomplete. Medial fork arises basal to apex of CuA2 and radial fork situated distal to the apex of CuA2. R5 ends beyond wing apex. Bases of M3, CuA1 and CuA2 not markedly connected. Halteres ( Fig. 12View FIGURES 8 – 13) stick-shaped, knobs covered with minute pedunculate scales; ratio maximum length to maximum width of halter 2.1:1.
Male genitalia with ejaculatory apodeme (basiphallus) almost elongate rectangular in dorsal view and stickshaped in lateral view ( Figs 14, 15View FIGURES 14 – 17). Aedeagal complex dorso-ventrally flattened, spatulate structure (parameral sheath) with a pair of lobuli distally, with a shallow cleft in between. Distiphallus ( Fig. 14View FIGURES 14 – 17) with paired trifid sclerites (proximal and distal pointed protuberances in line with both lamellae of distiphallus, outer strong protuberance is directed backwards to basis of distiphallus). Sometimes acute tip is doubled –the paratype from the bank of Bylnička brook. „Glenoid blades“ not visible, only partially developed. Furca developed ( Fig. 17View FIGURES 14 – 17). Gonocoxites ( Figs 14, 16View FIGURES 14 – 17) regularly cylindrical. Gonostyli thin, slightly bent, gradually tapering to acute end, 1.5 times as long as gonocoxites. Epandrium ( Figs 19, 20View FIGURES 18 – 20) bare in its proximal part, with some caudal hair insertions on both sides of the deep epandrial notch. Middle aperture transversely prolonged, approximately kidney-shaped, considerably sclerotized in perimeter. Remainder of ventral epandrial plate well bordered, but only membraneous. Almost entire hypandrium narrow ( Fig. 14View FIGURES 14 – 17), however, with more or less developed lobate protuberance in the middle. Hypoproct twice as long as semicircular epiproct, hypoproct almost tongue shaped or triangular, with rounded caudal tip; both parts microsetose ( Figs 19, 20View FIGURES 18 – 20). Surstyli ( Figs 19, 20View FIGURES 18 – 20) more than 1.5 times longer than epandrium, slightly C-shaped from lateral view, subapically with stable number of 12 retinaculi which are gradually shorter towards top of surstylus. Retinacula are apically frayed ( Figs 19, 20View FIGURES 18 – 20).
Differential diagnosis. Jungiella janiki sp. nov. differs from J. calcicola Vaillant, 1972 by the hypandrium with central lobate protuberance without distal cleft in the middle, the proximally almost square ejaculatory apodeme, the trifid sclerite of aedeagal complex not surrounded by a sclerotized ring, divergent distal arms of trifid sclerites (sometimes acute tips are doubled), shallow cleft between distal lobuli of aedeagal complex (all previously mentioned characters see Fig. 14View FIGURES 14 – 17) and surstylus subapically with 12 retinacula ( Fig. 19View FIGURES 18 – 20). The holotype of J. calcicola (based on the original description) has a bilobed hypandrium with a central shallow cleft, proximally rounded ejaculatory apodeme, trifid sclerite of aedeagal complex surrounded by a sclerotized ring, convergent and simple distal arms of trifid sclerites, deep cleft between distal lobuli of intromitten region and surstylus subapically with 9 retinacula ( Vaillant, 1972). Jungiella geniculata Krek, 1971 has acute tips of distal arms of trifid sclerites of aedeagal complex doubled as sometimes janiki , however, convergent. All three mentioned species belong to the subgenus Psychocha , where only rudimentary joint coupling of paired caudal sclerites („glenoid blades“) inside of spatula is visible.
Etymology. The species is named after Miroslav Janík, protector and head of the Folk Museum Building in Valašské Klobouky (known as Kosenka), situated near the Bílé Potoky NR, where the holotype was collected.
