Melanagromyza cuprea Guglya , sp. n. ( figs 19–29 )

Type material. Holotype Ơ: Ukraine: Sumy Region: Vakalivshchyna (51°02ʹ N, 34°55ʹ E), 12.06.2013, on leaves of Sambucus nigra L. (No Н-83) (Guglya) (dissected). Paratypes: Sumy Region: 2 Ơ, 1 ♀, labels as in the holotype (No Н-84, H-85, H-86) (♀ dissected); 1 Ơ, same locality, 14.06.2010, 11.00, dry motley grass under trees (No Н-87) (Guglya) (dissected); 1 Ơ, Kharkiv Region: near Rubizhne (50°10ʹ N, 36°47ʹ E), 17.08.2014, 15.30, high and thick grass in the forest stand of Robinia pseudoscacia L. and Pinus sp. (No. Н-88) (Guglya) (dissected).

D e s c r i p t i o n. Head ( figs 19 – 20 ). Orbit projected above eye in profile; 2–4 orb s, 3 fr s (in holotype 3 orb s, 3 fr s); frorb sta in two rows, reclinate and proclinate together; orbit wide and shining (frontal view); frontal carina of medium width, visible only pedicel at level; lunule slightly shining, high, rounded dorsally, without distinct furrow, but with elongated hollow near frontal carina; ocellar triangle matt, wide, reaching the level between 3rd orb s and 1st fr s, with distinct contours; frons matt; vibrissa longer than sbvb s; maximum height of eye 3.8× as high as gena; gena angular; 1st flagellomere elongated (lateral view).

Wing ( fig. 25 ) slightly yellowish, with all veins brown; costa reaching M 1; last section of CuA 1 0.7× as long as penultimate; costal sections 2–4 in the ratio of 3.85: 1.21: 1.00; calypter and fringe yellowish, margin orange. Wing length 2.75 (Ơ) to 3.35 mm (♀).

Mesonotum strongly green shining (dorsal view); scutellum matt, with coppery undertone; abdomen shining coppery-green; 4 dc (2 strong and 2 much slender and short) ( fig. 26 ); ac black, in 10 irregular rows at level of 2nd dc; halter and legs dark brown.

Male terminalia ( figs 21 – 24 ). Epandrium covered with long hairs; cerci with long hairs only; inner surface of surstylus with numerous, not long, but strong setae; hypandrium Y-shaped (ventral view); ejaculatory apodeme longer than phallus; phallus 0.22 mm long: distiphallus complex elongated, oval and narrowing posteriorly (ventral view); mesophallus of medium length, rounded apically; basiphallus short, wide and rounded anteriorly.

Female terminalia ( figs 27 – 29 ). Both spermathecae suboval, of different size, dark brown, with flattened base; collars present in both spermathecae, but of different shape; egg guide relatively wide, 3.9× as long as maximum width, acute apically and 4.3–6.2× as long as length of spermatheca; middle and ventral part of medial membrane covered with numerous small brown teeth and one row of small teeth located apically along dorsal margin; ventral seminal receptacle as on fig. 29.

B i o n o m i c s. Two generations are recorded, in June and August. Host plant unknown.

D i a g n o s i s. The new species differs from all other Melanagromyza species by the combination of strongly shining orbits (frontal view); medium sized frontal carina; lunule with elongated hollow near frontal carina; mesonotum strongly green shining (dorsal view); scutellum matt, with coppery undertone; abdomen strongly shining coppery-green; two additional small dc; basiphallus short, wide and rounded anteriorly; inner surface of surstylus with numerous, not long, but strong setae.

E t y m o l o g y. The name reflects the copper sheen of the mesonotum and abdomen.
