Description (male, holotype). Head pale brown, frons ochre brown, ocellar triangle and fronto-orbital plate subshining. Occiput blackish brown, both vertical setae inside dark area. First flagellomere and pedicel blackish brown, scape ochre.Antennal cavities blackish brown. Gena brown, parafacialia ochre brown. Lunule brown. Scutum and scutellum blackish brown, matt. Notopleuron and postpronotal lobe brown. Wing hyaline, base of wing and veins ochre brown, calypters grey, their margin and fringe yellow. Halteres ochre yellow, knob brown in upper half ( Fig. 61 ). Legs brown.

Head ( Figs. 59–60 ). Frons about as wide as 1.46 width of eye at level of anterior ocellus, slightly tapering toward lunule. Fronto-orbital plate about 0.21 width of frons, protruding as a narrow ring in front of eye in profile. Two strong reclinate ors setae present, upper of them with outwardly bent tip, 2–3 inclinate and slightly reclinate ori setae, lower shorter and thinner. Orbital setulae reclinate. Bases of antennae separated in distance equal 0.4 scape width. Arista only 0.73 times as long as eye is high, short setulose. Gena highest in posterior part, reaching 0.41 height of eye, parafacialia narrow. One vi seta and 6 ge setae present. Eye totally bare.

Scutum with 3 strong and long postsutural dc setae, and 6 additional anterior dc setulae being not longer than acr setulae. Acrostichal setulae in 4 rows, gradually reduced anteriorly. One prsc seta present, twice as long as acr setulae. Two ntp setae present, posterior one shorter and weaker, reaching only 0.63 length of anterior notopleural. Scutellum broader than long, index 1.5. All usual setae present: 1 oc, 1 pvt, 1 vte, 1 vti, 1 ppl, 1 hu, 1 mspl, 1 stpl, 1 sa, 1 prs, 1 bs, 1 as.

Wing ( Fig. 58 ) 1.88 mm long. Costa extending at tip of M 1, wing apex close to M 1. Costal sections 2–4 in the ratio of 3.75: 1.05: 1.00. Distance between cross veins R-M and DM-Cu equal 0.63 length of DM-Cu. Last section of CuA 1 2.5 times longer than penultimate.

Legs. Mid tibiae without pd setae.

Abdomen oval, 6 th tergite 1.5 times longer than 5 th tergite. Male terminalia ( Figs. 61–67 ): epandrium oval, 1.23 times broader than high, without caudal projection. Surstylus ( Fig. 64 ) with group of setae on inner side. Epandrium broadly oval, with several setae on inner and ventral side. Cerci reaching 0.31 height of epandrium. Phallus ( Figs. 62–63 ) about 0.5 length of phallapodeme, distiphallus complex symmetrical, conspicuously black and strongly pigmented with characteristic surface structure. Mesophallus heart-shaped and slightly pigmented. Basiphallus consisting of set of narrow asymmetric arms. Ejaculatory apodeme ( Figs. 65–66 ) V-shaped, 1.54 times as long as broad, with a distinct bowl-shaped base, extremely pigmented. Hypandrium ( Fig. 67 ) U-shaped, weakly pigmented.

Female. Unknown.

Body length (J ♀) 2.02–2.28 mm (holotype 2.12 mm).

Variability. Compared with the holotype, the other specimens do not differ in the colour. Only the following characters are apparently variable: the width of the frons is 1.36–1.60 times broader than eye, the wing is 1.90–1.95 mm long, costal sections 2–4 are in the ratio of 3.16–3.33: 1.16–1.35: 1.00, the length of the last part of CuA 1 varies between 2.22–2.60.

Differential diagnosis. Amauromyza (Amauromyza) rameli sp. nov. resembles Oriental A. (A.) aliena (Malloch, 1914) and A. (A.) crucifera Sasakawa, 2007 , from Nepal. Amauromyza (A.) aliena is distictly larger, the female body is 2.75 mm long, the frons is black, calypters grey, their margin and fringe blackish brown, halteres are blackish brown, the frons is broad as an eye, acr setulae are arranged in 10 rows, mid tibiae have pd setae, the last section of CuA 1 is shorter than the penultimate. Amauromyza (A.) crucifera possesses the male wing length 2.3 mm, antennae black, calypters brownish, with the fringe pale brown, halteres with the stalk yellow and the knob brown, acr setulae are in 6 rows, the last section of CuA 1 is twice as long as the penultimate. The structures of male terminalia are markedly different and indicate separate species (see SPENCER 1962; SASAKAWA 1972, 2007).

Etymology. This species is named in honour of Gordon Ramel, member, head of the Management Authority of Wetland Kerkini, in recognition of the enormous work he put into the Project Kerkini.

Bionomics. Unknown.

Distribution. Greece ( Macedonia): Kerkini. Hitherto known only from the type locality.
