Dicranomyia (Dicranomyia) pallidinota sp. n.

Figures 4 , 11

Diagnosis. Large 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 large; rostral spines very short, straight. Wing length 6.5–9.2 mm.

Description. Male. Head. Antenna pale brown, slightly longer than in other species (except for magninota sp. n.), extending to about anterior margin of prescutum. Flagellomeres, especially distal ones, long-ovoid, with yellow bases and 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 ( Fig. 11 ) hyaline, iridescent. Wing pattern pale brown; 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 long, proximal section of M1+2 (anterior margin of discal cell) mostly longer than distal section. Tip of A2 about opposite Sc2. Halter with knob slightly infuscated. Legs with tips of femora slightly and narrowly darkened. Tarsi with tarsal claws slightly longer than half length of tarsomeres 5.

Abdomen yellowish brown. Male terminalia ( Fig. 4 ): Tergite 9 with shallow median emargination at posterior margin. Gonocoxite comparatively short, about half length of ventral gonostylus. The latter ovoid, comparatively large, about 1.5 times as long as broad, only slightly enlarged medially in proximal part, with rostral prolongation short, directed more or less medially. Rostral spines very short, straight and pale, slightly shorter than rostrum from base of more distal spine to apex.

Female resembling male in general appearance.

Etymology. The name of this species, pallidinota , combined from pallidus (= pale) and nota (= the spot, mark), refers to its pale brown wing pattern. A noun in nominative singular, standing in apposition to the generic name.

Discussion. In general appearance, D. (D.) pallidinota sp. n. resembles D. (D.) lorettae in its pale brown colouration, including the wing pattern. The latter species is, however, considerably different in the structure of the male terminalia (see Discussion of lorettae ). The large and broad ventral gonostylus relates D. (D.) pallidinota sp.n. rather with D. (D.) luteipennis and D. (D.) magninota sp. n. From both, D. (D.) pallidinota sp. n. differs, apart from significant traits in the body colouration and the wing pattern, by very short rostral spines (cf. Figs 4 and 1, 3 ).

Distribution. Bulgaria, Greece, France ( Corsica); Lebanon, Syria.
