Macrorrhyncha muglensis View in CoL sp. n.

( Figs 4–6 View Figs 1–6 )

Diagnosis. This species resembles M. geranias , M. anatolica and M. thracica in having a bare mediotergite, proboscis longer than eye height, dorsal process of gonocoxite narrow in lateral view and gonostyle not elongate. M. muglensis differs from M. geranias in the entirely black coloration and having distal margin of tergite 9 with a trapezium-shaped emargination ( Fig. 10 View Figs 7–12 ) in M. geranias , U-shaped emargination ( Fig. 4 View Figs 1–6 ) in M. muglensis . The new species differs from M. anatolica in the presence of clear visible fold in the lateral margin of tergite 9 ( Fig. 4 View Figs 1–6 ). Differences from M. thracica are the presence of a large fold in the lateral margin and U-shaped emargination in the distal margin of tergite 9 ( Fig. 4 View Figs 1–6 ), joined by a narrow bridge ventrally gonocoxites and gonostyle more or less triangular in ventral view ( Fig. 5 View Figs 1–6 ) in M. muglensis .

Description

Male. Body length 5.0 mm (n=1). Wing length 3.6 mm.

Coloration (specimen in alcohol). Head brown, mouthparts yellowish. Antenna brownish yellow. Mesoscutum brownish yellow, paler on periphery, with three indistinct slightly darkened stripes. Scutellum brownish yellow. Mediotergite brownish yellow. Antepronotum and proepisternum yellow brownish, other pleurae brownish yellow. Unmarked, yellowish. Veins yellowish brown. Haltere yellow. Legs yellow with dark bristling, spurs dark brown. Abdomen yellow brownish, with dark bristling. Tergite 9 and gonocoxites brown, gonostyles paler.

Head. Antenna about as long as thorax. Flagellomeres 2–8 a little longer as broad. Proboscis as long as height of head. Palpus little longer than proboscis. Lateral ocellus about its diameter distant from eye margin.

Thorax. Mesoscutum with long dark setae situated above base of wing. Strong dorsocentral and acrostichal setae absent. Scutellum with several black setae. Mediotergite bare. Antepronotum and proepisternum with some small black setae. Some small posterior prospiracular setulae present. Other pleurae bare.

Wing. Costa extends about 0.3 distance from R 5 to M 1. Sc apically unclear. R 4 short, ending in costa about twice its length from tip of R 1. R 4 short, ending in costa about twice its length from tip of R 1. CuA 2 fading before wing margin. Veins setose: C, Sc, frm, stem of R 4, R 5; bare: Sc, Rs, R 4, bM-Cu, stem of M and Cu, CuP, A 1.

Legs. Tibiae with irregular setulae and with short strong setae in irregular series. Ratio basitarsus I: tibia I = 0.75.

Male terminalia ( Figs 4–6 View Figs 1–6 ). Lateral margin of tergite 9 with distinct medially directed fold, distal margin with U-shaped emargination ( Fig. 4 View Figs 1–6 ). Gonocoxites joined by a narrow bridge ventrally and with internal process with a long apical seta ( Fig. 5 View Figs 1–6 ). Dorsal process of gonocoxite in lateral view not enlarged distally ( Fig. 6 View Figs 1–6 ). Gonostyle more or less triangular in ventral view ( Fig. 5 View Figs 1–6 ).

Female. Unknown.

Etymology. The name is an adjective referring to occurrence in the province of Muđla, Turkey.
