Diagnosis. Medium-sized species. Body colouration brown to dark brown. Wing pattern dark brown, with all anterior spots distinct, of moderate extent, smaller than their interspaces. Male terminalia with ventral gonostylus moderate in size; rostral spines short and straight. Wing length 5.3–9.2 mm.

Description. Male. Head. Antenna brown to dark brown, short, not extending to anterior margin of prescutum. Flagellomeres short-ovoid, with longest verticils subequal in length to their respective segments.

Thorax generally brown to dark brown, with greyish pruinosity. Pronotum dark brown throughout. Prescutum with median area more darkened. Pleuron somewhat paler than dorsal parts of thorax. Wing ( Fig. 9 View FIGURES 8 – 12 ) slightly tinged brownish. Wing pattern dark brown; all anterior spots distinct, of moderate extent, smaller than their interspaces. Distinct, broad seam along outer cord, including distal section of Cu. Another seam along distal margin of discal cell. 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 mostly beyond Sc2. Halter with knob moderately infuscated. Legs with tips of femora dark brown. Tarsi with tarsal claws about half length of tarsomeres 5.

Abdomen brown to dark brown. Male terminalia ( Fig. 2 View FIGURES 1 – 7. 1 – 6 ): Tergite 9 with shallow median emargination at posterior margin. Gonocoxite moderately long, about two-thirds length of ventral gonostylus. The latter ovoid, moderate in size, about 1.6 times as long as broad (in fact more slender than in luteipennis , magninota sp. n. and pallidinota sp. n.), moderately enlarged medially in proximal part, with rostral prolongation short, directed more or less medially. Rostral spines short, straight and pale, slightly longer than rostrum from base of more distal spine to apex.

Female resembling male in general appearance.

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

Discussion. Dicranomyia (Dicranomyia) fuscinota sp. n. is responsible for most of the published records of D. (D.) luteipennis . Externally, it differs from the latter by its mostly dark brown body colouration and a complete wing pattern, with all anterior spots distinct, so that the seam along the outer cord, also fairly distinct, sometimes even broader than that in D. (D.) luteipennis , appears just as a part of the numerous other markings ( Fig. 9 View FIGURES 8 – 12 ). By contrast, the wing pattern is considerably reduced in D. (D.) luteipennis , and the seam along the outer cord fused to the pterostigma remains thus the most conspicuous mark ( Fig. 8 View FIGURES 8 – 12 ). In the structure of the male terminalia, the distinctions between the two species are less striking but obvious (cf. Figs 2 and 1 View FIGURES 1 – 7. 1 – 6 ). In D. (D.) fuscinota sp. n., the ventral gonostylus is relatively smaller (shorter) than in D. (D.) luteipennis , longer than the gonocoxite by about one third its length, and somewhat more slender, whereas, in D. (D.) luteipennis , it is large, twice the length of the gonocoxite, and distinctly broader. The rostral spines are short and straight in D. (D.) fuscinota sp. n. (longer and slightly curved in D. (D.) luteipennis ). Male tarsal claws are slightly shorter in respect to tarsomere 5 than those of D. (D.) luteipennis . In fact, D. (D.) fuscinota sp. n. more resembles D. (D.) magninota sp. n. and D. (D.) pallidinota sp. n., sharing with them a complete wing pattern and comparatively short rostral spines, it differs, however, from both, as from D. (D.) luteipennis , by a somewhat smaller and narrower ventral gonostylus.

The drawings of the male terminalia published under D. (D.) luteipennis by Geiger (1985) and copied under the same name by Geiger (1986b) and Podenas et al. (2006) most probably pertain to D. (D.) fuscinota sp. n. The genitalia, however, are distorted in these figures, giving the ventromesal lobe an unrecognizable shape. Moreover, the ventral gonostylus, surprisingly, really suggests that of D. (D.) luteipennis by its considerable size and breadth. This must have arisen as a result of inaccuracy of reproduction or deformation of the hypopygium. The original figure was apparently drawn from a specimen in MHNN where no material of D. (D.) luteipennis was found, and the respective redescriptions ( Geiger 1985: 55, 1986b: 75) clearly refer to a species with a complete wing pattern.
