Dicranomyia (Dicranomyia) lorettae Geiger 1985: 58 (description), 59 (key), Figs 12 –16 (male terminalia). Dicranomyia (s. str.) lorettae: Geiger 1986b: 60 (key), 74 (redescription), Figs 150–151 (male terminalia, copied from Geiger 1985).
Dicranomyia (Dicranomyia) lorettae: Savchenko et al. 1992: 336 (Palaearctic catalogue). Dicranomyia (Dicranomyia) lorettae: Podenas et al. 2006: 157 (figure only), Fig. 68.6 (male terminalia, copied from Geiger 1985).
Diagnosis. Medium-sized species. Body colouration yellowish brown. Wing pattern pale brown, with all anterior spots distinct, of moderate extent, smaller than their interspaces. Male terminalia with ventral gonostylus moderate in size and rather slender; rostral spines moderate in length, straight. Wing length 5.4–7.8 mm.
Description. Male. Head. Antenna pale brown, short, not extending to anterior margin of prescutum. Flagellomeres mostly short-ovoid, with longest verticils subequal in length to their respective segments.
Thorax generally yellowish brown, with whitish pruinosity. Pronotum and prescutum yellowish brown, slightly darkened medially. Pleuron somewhat paler than dorsal parts of thorax. Wing hyaline, iridescent. Wing pattern pale brown, much as in D. (D.) pallidinota sp. n.; all anterior spots (except sometimes spot 1) distinct, of moderate extent, smaller than their interspaces. Moderately distinct seam along outer cord, including distal section of Cu. Another seam along distal margin of discal cell. Apex of wing slightly infuscated. Other markings poorly distinct. Sc1 without macrotrichia. Wing venation with discal cell moderate in length, with proximal section of M1+2 (anterior margin of discal cell) from slightly longer to slightly shorter than distal section. Tip of A2 about opposite Sc2. Halter with knob slightly infuscated or infuscation indiscernible. Legs with tips of femora moderately darkened. Tarsi with tarsal claws about half length of tarsomeres 5.
Abdomen yellowish brown. Male terminalia (Fig. 5): Tergite 9 with median emargination at posterior margin slightly more pronounced than in other species. Gonocoxite moderately long, about two-thirds length of ventral gonostylus. The latter moderate in size, rather long-ovoid, about 1.7 times as long as broad (yet still more slender than that in fuscinota sp. n.), moderately enlarged medially in proximal part, with rostral prolongation longer than in other species, comparatively slender, directed more anteriorly. Rostral spines moderate in length, straight and pale, longer than rostrum from base of more distal spine to apex.
Female unknown.
Type material examined. Paratype: Switzerland: Canton Ticino: Vezia, S. Martino (410 m), 6.- 12.viii. 1979, 1 3 (C. Dufour & W. Geiger leg.; light trap) (JSO; dried from ethanol)
Other material examined (7 3). Greece: Ikaria Is., Milopo-Monokampion (280–650 m), 37º 39', 26º 20', 22.v. 1973, 1 3 (H. Malicky leg.) (ZFMK; in ethanol). Italy: Liguria: Toirane (SV), Torr. Varatella (80 m), 14. vi.2005, 2 3. Piemonte: Borgomale (CN), Torr. Berria (340 m), 8.v. 2001, 2 3; Macra (CN), lungo la ss 22, c/o fontana (820 m), 5.vii. 2000, 1 3 (all G.B. Delmastro leg.) (all JSO; dried from ethanol). Switzerland: Canton Valais: Fully (550 m), 13.–19.x. 1980, 1 3 (C. Dufour & W. Geiger leg.; light trap) (JSO; in ethanol).
Discussion. Although D. (D.) lorettae most closely resembles D. (D.) pallidinota sp. n. in its pale body colouration and wing pattern, it differs considerably from it and all the other species by the structure of the male terminalia. The emargination at the posterior margin of tergite 9 is more pronounced than in the other species, the ventral gonostylus is much more slender, with the rostral prolongation rather long and directed more anteriorly, and the rostral spines are longer (Fig. 5).
Distribution. Switzerland (Geiger 1985, 1986b, Podenas et al. 2006). First records for Greece and Italy.
