Dicranomyia (Dicranomyia) magninota View in CoL sp. n.

Figures 3 View FIGURES 1 – 7. 1 – 6 , 10 View FIGURES 8 – 12

Diagnosis. Large species. Body colouration deep dark brown. Wing pattern dark brown, with all anterior spots distinct and large, subequal in extent to their interspaces. Male terminalia with ventral gonostylus large; rostral spines short, straight. Wing length 7.4–8.3 mm.

Description. Male. Head. Antenna dark brown, slightly longer than in other species (except for pallidinota sp. n.), extending to about anterior margin of prescutum. Flagellomeres, especially distal ones, long-ovoid, with longest verticils subequal in length to their respective segments.

Thorax generally deep dark brown, with greyish pruinosity. Pronotum and prescutum dark brown throughout. Pleuron concolorous with dorsal parts of thorax. Wing ( Fig. 10 View FIGURES 8 – 12 ) slightly tinged brownish. Wing pattern dark brown; all anterior spots distinct and large, subequal in extent to their interspaces. Distinct, moderately broad seam along outer cord, including distal section of Cu. Another seam along distal margin of discal cell. Poorly distinct seam along proximal section of Cu (proximal to m-cu). Slight clouds over tips of all longitudinal veins. Sc1 without macrotrichia. Wing venation with discal cell short, proximal section of M1+2 (anterior margin of discal cell) from subequal in length to to shorter than distal section. Tip of A2 about opposite Sc2. Halter with knob moderately infuscated. Legs with tips of femora dark brown. Tarsi with tarsal claws slightly longer than half length of tarsomeres 5.

Abdomen dark brown. Male terminalia ( Fig. 3 View FIGURES 1 – 7. 1 – 6 ): Tergite 9 with shallow median emargination at posterior margin. Gonocoxite very dark compared to other species, comparatively short, about half length of ventral gonostylus. The latter ovoid, comparatively large, about 1.4 times as long as broad, only slightly enlarged medially in proximal part. Rostral prolongation short, directed more or less medially. Rostral spines short, straight and pale, from subequal in length to to slightly longer than rostrum from base of more distal spine to apex.

Female unknown.

Material examined. Holotype 3: Spain, Andalucía, Jaén, Rio Aguamula, Sierra de Cazorla (700 m), 23.iv.1994 (P. Oosterbroek & C. Hartveld leg.) ( ZMAN). Paratypes (6 3): Spain: Andalucía: Jaén, Rio Guadalquivir, Sierra de Cazorla (900 m), 22.iv. 1994, 1 3; Jaén, Rio Aguamula, Sierra de Cazorla (700 m), 23.iv. 1994, 5 3 (all P. Oosterbroek & C. Hartveld leg.) ( ZMAN, JSO).

Etymology. The name of this species, magninota , combined from magnus (= large) and nota (= the spot, mark), refers to its large anterior spots on the wing. A noun in nominative singular, standing in apposition to the generic name.

Discussion. From all the species, including D. (D.) fuscinota sp. n., otherwise similar in its complete dark brown wing pattern, D. (D.) magninota sp. n. differs by large anterior spots subequal in extent to their interspaces (anterior spots are smaller than their interspaces in D. (D.) fuscinota sp. n.) (cf. Figs 10 and 9 View FIGURES 8 – 12 ). In the structure of the male terminalia, D. (D.) magninota sp. n. resembles D. (D.) luteipennis and D. (D.) pallidinota sp. n. in having a large and broad ventral gonostylus, being intermediate between them in the breadth of the latter and in the length of the rostral spines (cf. Figs 3 and 1, 4 View FIGURES 1 – 7. 1 – 6 ). The gonocoxite is conspicuously darkly pigmented in D. (D.) magninota sp. n.
