Mycomyiella elegans View in CoL new species

(Figs 7–10)

Type material: Holotype male, TANZANIA, Tanga region, West Usambara Mountains, Mazumbai, 4–6.xi.1990, ZMB's Tanzania Expedition, ( ZMUN). Paratypes: as for holotype except 1 male, 7–12.xi.1990; 1 male, 20–26.xi.1990; 1 male 22.xi.1990.

Etymology: From Latin elegans , tasteful, fine, referring to the very long and slender genital structures.

Diagnostic characters: The male groups with M. diseta new species and M. tannerorum new species in having a forked gonostylus and gonocoxite with long lobes. It can be separated from both species by having very long, sinuous lobes of tergite 9. The species appears more slender and more strongly colored than the other species in the genus.

Coloration: Head light brown to brown. Palpomeres and other mouthparts brown. Ocellar area dark brown. Face yellow, posterior parts of head brown. Antennae light yellow to yellow; scape, pedicel and base of first flagellomere lighter than rest of antennae. Antepronotum yellow. Scutum light brown to brown, with 3 yellow longitudinal bands. Anepisternum and preepisternum yellow. Scutellum light brown to brown. Laterotergite yellow, mediotergite yellow­brown. Coxae yellow, femura light brown, tibiae and tarsi brown. Tergite 1 brown; tergite 2 yellow; tergite 3 brown with median, yellow patches anteriorly and posteriorly; tergite 4 yellow with median, brown patches anteriorly and posteriorly, tergite 5 brown; tergite 6 brown with posterior, yellow band; tergite 7 yellow. Sternites 1–4 yellow; sternite 5 yellow with large, brown, lateral patches; sternites 6–7 yellow. Terminalia light brown to brown.

Head: Head 0.47–0.50, 0.48 mm long; 0.50–0.53, 0.51 mm wide. First flagellomere about 2.0 times as long as wide, second flagellomere as long as wide. Clypeus 0.11–0.14, 0.12 mm long; with lateral and apical setae. Ocellar area 0.11–0.12, 0.11 mm wide; placed below upper margin of compound eye. Some setae in front of ocellar area. Posterolateral portion of frons densely setose, setae reaching just below ocellar area. Face bare. Mouthparts elongated. Palpomere 4 with 2–5 setae proximally, palpomere 3 with several setae in proximal two­thirds. Palpomere ratios (2–5) as: 1.00: 3.25: 3.00: 4.50.

Thorax: Total length 0.96–1.07, 1.00 mm. Scutum 0.85–0.91, 0.88 mm long; scutellum 0.11–0.13, 0.12 mm long.

Legs: Leg measurements and ratios as in Tables 4 & 5.

Wings: Wing 3.09–3.20, 3.12 mm long; 1.10–1.20, 1.12 mm wide. Sc ending in R1 slightly distally to middle of small cell. Sc with 6–14, 9 macrotrichia apically. R4/Rs­cell about 2.0 times as long as wide. Small cell 0.15–0.22, 0.20 mm long. CuA fork slightly distal to M fork. Wing measurements are given in Table 6 View TABLE 6 .

Abdomen: Abdomen 2.15–2.49, 2.38 mm long; tergite 5 0.49–0.64, 0.57 mm wide.

Male terminalia (Figs 7–10). Tergite 8 wide, with 5 setae posteriolaterally. Tergite 9 narrow, with 4–5 setae laterally, with long, heavily sclerotized, setose lobes. Gonocoxite with lateral setae; with long, curved lobes; and subtriangular, setose lateral prolongation. Gonostylus deeply forked; with slender, curved, setose forks. Aedeagus small, covered with short setae and with long setae subapically. Sternite 8 large, evenly rounded apically, densely setose in apical one­half.

Female: Unknown.

Distribution: Known from the type locality in the West Usambara Mountains in North­East Tanzania only.
