( Figs. 1–24 ) Type locality. Czech Republic , south-western Moravia , Dyje river valley between the towns of Vranov nad Dyjí (in the west) and Znojmo (in the east) along the Czech-Austrian state border, forest, 420 m a.s.l., 48°51′30″N 15°51′35″E . Type material. HOLOTYPE : J, South Moravia , Podyjí NP , Hardegg , creek near view point, forest, 420 m a.s.l. , 48°51′30″N 15°51′35″E , 21.v.–12.vi.2003 , MT , M. Barták and Š. Kubík leg., Slide Cat. No. 34622, Inv. No. 19879 ( NMPC ). Description. Male . Head ( Figs. 1 , 9 ) distinctly broader than high (1.5: 1, measured to the base of mouth parts), rounded in the area of vertex ( Fig. 9 ), with two small sclerotized protuberances terminally, divided by a deep cleft ( Fig. 1 ). Eyes large, widely separated, hardly as wide as frons, with an eye fold (compare caudal view in Figs. 2 , 9 ). Facets as in Fig. 2 . Foramen magnum oval, sclerotized, with characteristic protuberances (wings) terminally ( Figs. 1 , 9 ). Supraocular lateral bristles long (6–8, see conspicuous setae alveoli), isolated on the dorsal margins of eyes, forming one line ( Fig. 1 ), in contrast to the back fold with two lines medially ( Fig. 9 ). Vertex densely haired, with a ventral ostensible triangular extension of not densely spaced alveoli, frontoclypeus with only several scattered alveoli near mouthparts. The antennae are 15-partite ( Figs. 3 , 10 ) and haired. Scape short, asymmetrically barrelshaped, pedicel spherical, shorter than longest side of scape ( Fig. 10 ). First flagellomere spindle shaped, elongate, 1.7 times as long as pedicel, following flagellomeres tear-shaped with a pair of simple ascoids, which are very long (mostly longer than the flagellomere) and flaunted. The last two antennomeres are rod-shaped, slightly narrowed in the central part, the terminal flagellomere with a short thick apiculus (digit) carrying very small sensory seta apically. The mouthparts inconspicuously extend beyond the basal palpomere ( Fig. 9 ). Maxillary palpus 3-partite ( Figs. 11 , 17 ), basal palpomere irregularly spindle-shaped from different views, widened in the middle, with a circular sensory depression (presumably normally carrying cluster of sensilla) in the second third, second palpomere almost cylindrical and terminal palpomere elongated, ovoid. The length ratios of the maxillary palpomeres: 1.9: 1.0: 1.0. Maxilla approximately as long as the first palpomere, with sparse short hairs ( Figs. 17, 18 ). Origin of labial apodeme tridentate with two parallel narrow rods, the cleft between haired terminal lobes of the labium has a shallow apical concavity ( Fig. 19 ). The ratio of the maximum length of the cibarium to the length of the epipharynx is 1.5: 1, labrum with sparse alveoli ( Figs. 1, 4 ). Thorax elongate, low humped, thoracic sclerites as in Fig. 20 , spiracular area as in Fig. 5 . Wings ( Figs. 7 , 12 ) narrowly lancet-shaped, 2.4 mm long, almost translucent, only inconspicuously fuscous, with anal area slightly enlarged, both forks before level of tip of CuA 2 (medial fork undistinguished almost at the same level). Sc long, strengthened distally and terminating both in C and R 1 , crossvein sc-r. Ends of R 1 , R 2 , R 3 , R 4+5 , M 1 , M 2 , M 3 , CuA 1 , CuA 2 and A 1 weakened. R 1 strengthened, shortly bent to the crossvein connection, straight distally. R 2+3+4+5 very short, bent and strengthened. R 4+5 only inconspicuously bent to radial fork, strengthened, extending distally to reach wing margin below apex of the wing. CuA 1 and CuA 2 conspicuously strengthened, A 1 only basally. Not strengthened veins: R 2+3 , R 2 , R 3 , M 1+2 , M 1 , M 2 , M 3 , CuA 2 basally and A 1 distally. M 3 connected basally with CuA 1 close to a short trace of a crossvein sc-r. Wing indices AB: AC: AD = 3.3: 3.7: 4.1; BC: CD: BD = 1.0: 1.5: 2.5. Maximum wing length equal to 2.5 times its maximum width. Median wing angle is 159° (BCD). Neala not developed, anal area with characteristic patches of alveoli (see detail in Fig. 7 ). Halteres ( Fig. 6 ) knob(stick)-shaped, setose and haired, surface finely corrugated, maximum length of haltere (measured to the basal constriction) equals 2.7 times its maximum width. Ratios of lengths of femora, tibiae and first tarsomeres: P 1 = 1.4: 1.4: 1.1; P 2 = 1.6: 1.9: 1.1; P 3 = 1.7: 2.3: 1.0; fore claws ( Fig. 8 ) very long and straight, tapering gradually (not abruptly), a little bent distally, bare. Figs. 1–8.

Scales: 2–4, 6 = 0.1 mm; 1, 5, 7 = 0.2 mm; 8 = 0.01 mm. Figs. 9–16. Trichomyia hardeggensis sp. nov. , male: 9 – head, caudal view; 10 – basal antennomeres; 11 – palpus maxillaris, dorsal view; 12 – wing; 13 – basal apodeme of aedeagal complex, dorsal view; 14 – same, lateral view; 15 – aedeagal complex and gonopods, dorsal view; 16 – gonopod and a part of aedeagus, lateral view. Scales: 11, 13–16 = 0.1 mm; 10 = 0.2 mm; 9 = 0.3 mm; 12 =1 mm. Basal apodeme of male genitalia from dorsal view narrow, a little widened in the middle, almost straight ( Fig. 13 ), inconspicuously bent in lateral view, with spatulate ending proximally ( Fig. 14 ). Aedeagal complex ( Figs. 15 , 21, 22 ) with a clear developed ovoid aedeagal chamber bordered by wide flattened rods, which are beside the end of a very narrow sclerotized slot (chink). They converge to the sclerotized tooth-like protuberances with parallel backward going V-shaped lateral arms, which are irregularly formed. Aedeagal complex is fixed in a pointed membranous sac composed of several folded layers. The auxiliary transverse rib at the end of aedeagal complex is developed and conspicuous ( Fig. 22 ). Gonocoxites swollen, basally with an elongate and narrow proximal apodeme; distally with two processes: a long prominent ventral process, covered with a row of strong bristles along its whole inner margin; and a not so prominent short and broad ventral process with several tips bearing strong setae. Small additional distal protuberances present, see Figs. 15 and 16 . Articulated gonostyli slightly bent and flattened, subapically hooked, as long as the aedeagal chamber ( Figs. 15, 16 ). Epandrium trapezoidal, sporadically setose on both sides, central aperture not developed ( Figs. 23, 24 ). Remainders of 10 th tergum and sternum inside of epandrium only membranous. Hypandrium narrow. Hypoproct obtusely triangular with narrowly rectangular base, epiproct inconspicuous, fold-shaped. Both parts haired. Surstyli ( Figs. 23, 24 ) large, leaf (blade)-shaped, setose, without tenacula. Figs. 17–24.

Scales: 18–19, 21–24 = 0.1 mm; 17, 20 = 0.2 mm. Female unknown. Differential diagnosis. The species described above has palpi with three palpomeres which is a character of the group B sensu DUCKHOUSE (1965) and is close genealogically with the species of subgenera Apotrichomyia Duckhouse, 1978 , Dactylotrichomyia Duckhouse, 1978 , Dicrotrichomyia Duckhouse, 1978 and Septemtrichomyia Bravo, 1999 in contrast to the species with four palpomeres of subgenera Gondwanotrichomyia Duckhouse, 1985 and Opisthotrichomyia Bravo, 2001 , both constituting group A sensu DUCKHOUSE (1965) . The elongate digit of the gonocoxite is reminiscent of Dactylotrichomyia Duckhouse, 1978 ; except in Dactylotrichomyia it is lateral rather than medial. A medial process is present in Dicrotrichomyia but this is not setose as it is in Trichomyia hardeggensis sp. nov. However, it is premature to assign the species to any extant subgenus until more information becomes available. The shape and the construction of the aedeagal complex in Trichomyia hardeggensis sp. nov. is unique compared with other Trichomyia . However, especially the male gonopods are very closely similar to T . stephani Beran, Doczkal, Pfister & Wagner, 2010 ; differences between males of the two species are summarized in Table 1. Etymology. The species name is derived from the name of Hardegg (from the old German words ‘hard’ = forest and ‘egg’ = rock, stone; figuratively meaning ‘strong house in the forest’), a small town in Austria , and adjacent view point on the opposite Moravian bank of the Dyje/Thaya river, both localities being situated in the Podyjí/Thayatal NP. Biology. Unknown. Distribution. So far known only from the type locality in the southern Moravia ( Czech Republic ).
