( Figs 9–13 )

Rhamphomyia cimrmani Barták, 2006: 504 .

Material examined. 35♂, 18♀, Turkey, Mugla University campus, 710 m, MT, 37°09'39''N, 28°22'20''E, xi.– iii.2013, M. Barták & Š. Kubík leg.

Specification of male characters. Frons with 1–2 pairs of setae on lower part; length of antennal segments = 7–13: 5–8: 46–50: 7–8; 14–18 acrostichals; postpronotum with 0–1 longer (often black) seta and 8–16 pale somewhat shorter setae; notopleuron with pale or dark setae in front part; laterotergite with pale setae or with several black setae intermixed; wing measurements: M2/d = 1.3–1.5, CuA1 ratio = 2.0–2.4, lw:ww = 2.8–3.3; abdominal sternite 1 with several pale setae; hypandrium with 4–7 setulae; length of body 2.9–4.3 mm, wing 3.0– 3.8 mm.

Description of female. Face shorter and broader than in male, about 0.15 mm long and 0.12 mm broad ventrally (at broadest point). All facets nearly equal in size. Occiput with somewhat shorter setae than in male. Labrum twice as long as height of head. Thorax as in male, only setae much shorter, both acrostichals and dorsocentrals about 0.10–0.15 mm long (only slightly longer than distance between rows of acrostichals and dorsocentrals). Hind basitarsus 4 times as long as broad. Abdomen more lustrous than in male, tergites 5–6 polished at least on posterior half, also lateral parts of preceding tergites more or less lustrous, first and last three tergites and all sternites microtrichose. Lateral parts of tergites 2–3 with setae about 0.15 mm long, setae on distal segments shorter, dorsum of abdomen with much shorter setae. Length of body 3.9–4.3 mm, wing 3.0– 3.4 mm.

Remarks. Rhamphomyia (L.) cimrmani was originally described from a single male specimen. Findings of additional materials enabled us to give more precise specification of male characters including their variations. Female is described here for the first time and images of both male and female including genitalia are added.

There are three species of the subgenus Lundstroemiella with microtrichose mesoscutum and long dark mesoscutal setae at least in males, viz. R. longefilata , R. cimrmani and R. granadensis Chvála. The last species differs from both former by broad frons in male and microtrichose abdomen in female (see key in Barták 2006). Differences between males: frons in R. longefilata is about as long as broad and lustrous at least in dorsal half but about 2–2.5 times as long as broad and entirely microtrichose in R. cimrmani ; face in R. cimrmani is about as long as frons but twice as long as frons in R. longefilata ; abdomen in R. longefilata is more lustrous and longer setose dorsally than in R. cimrmani ; R. longefilata has hypandrium with at most two short setae and cercus about as long as high, whereas R. cimrmani has hypandrium with many setae and cercus about twice as long as high. Female of R. longefilata has lustrous frons and R. cimrmani entirely microtrichose.
