DESCRIPTION

Male: Eyes holoptic, facets in ventral half of eye much smaller than in dorsal half. Frons (small area just above antenna and below ocellar triangle) black, microtrichose, setae absent. Ocellar setae black, about 1/3 as long as the distance between front ocellus and base of antenna, ocellar triangle mostly with 1 pair of additional similarly long setae on hind margin. Face brown, microtrichose, about 0.11 mm broad ventrally and 0.10 mm long, without setae. Occiput brownish black, microtrichose, sparsely black setose (setae on dorsal half of occiput arranged in two rows), postocular row remote from eye margin in middle part. Antenna brown to black, length of antennal segments (in 0.01 mm scale) = 7: 5-6: 16-19: 11-13, both basal antennomeres short setose (the longest setae about 0.05 mm long). Labrum brown, as long as or slightly shorter than head is high. Palpus brown, short, with 1-3 short setae. Gena very narrow, clypeus microtrichose. Thorax brownish black, microtrichose, mesoscutum uniformly dark brownish black, almost velvety black in dorsal view; without any stripes. All thoracic setae black. Chaetotaxy: 2-4 setae on proepisternum; both prosternum and proepisternal depression bare; 7-10 uniserial dorsocentrals (about 0.10-0.15 mm long in middle of their rows), 1-2 only slightly longer inclinate prescutellars; acrostichals absent; intrahumeral absent; one strong posthumeral (no additional setae laterad of dorsocentrals in presutural part of mesoscutum); 1 long postpronotal and 1-3 short additional setae; 2-3 notopleurals (0-1 shorter setae on anterior part of notopleuron); both supraalars and prealars absent; 1 strong and 1 small postalars; 4, rarely 5-6 scutellars; laterotergite with black setae. Fore coxa yellowish brown, distinctly paler than pleura, mid and hind coxae usually brown. Legs brown, microtrichose, hind femur (in some specimens also tibiae) lustrous, all setae on coxae and legs black. No seta in posteroapical comb on hind tibia. Fore femur with short setation (no prominent setae), anterior row of (sensory?) setae 0.03 mm long. Fore and mid tibiae with only short setation, without prominent setae (except preapicals on ventral part). Mid femur with short setation, no prominent setae except preapicals. Hind femur with short setation (ventrally almost bare in proximal 2/3), without prominent setae, except 1-2 preapicals ventrally. Hind tibia slightly broadened apically, with several setae dorsally slightly shorter than tibia is deep (only preapical dorsal seta may be longer), otherwise with short setation only. Basal tarsomeres of all legs thin and short setose, with short ventral setae. Measurements (in 0.01 mm scale): length: f1 (67-81), f2 (78-98), f3 (104-128), t1 (70-83), t2 (75-90), t3 (102-126), bt1 (40-46), bt2 (24-34), bt3 (48-56), width: bt1 and bt2 (4), bt3 (6). Wing light brown, stigma indistinct or only slightly darkened, veins brown, anal vein (A1) indistinct in distal half. Costal seta distinct axillary angle slightly obtuse. M2/D = 1.8-2.3, CuA1 ratio = 4.5-6.8, lw: ww = 3.1-3.3. Halter dark brown, calypter brown with dark fringes. Abdomen brown (lighter ventrally and almost velvety black in dorsal view), brown microtrichose, black setose. Hind marginal setae on sides of tergites 2-4 subequally long as their corresponding segments, on remaining segments shorter, discal setae shorter than marginals, dorsum of tergites with short setae, 1st sternite bare. Terminalia ( Fig. 2 ): hypandrium triangle-shaped in lateral view, with several strong and long setae, basal part connected with phallobase with narrow arms; cercus short and deeply concave dorsally; epandrium rounded apically, with a single spine at apex; phallus relatively short and broader in basal half than in apical half. Length of body 2.2-3.2 mm, wing 2.7-3.2 mm.

Female: Similar to male but with the following differences. Eyes dichoptic, facets subequal in size. Frons brown, microtrichose, 0.20-0.24 mm long and 0.08-0.10 mm broad, almost parallel sided, with 3-5 rather long (up to 0.10 mm) setae on each side. Face subequally broad as frons and 0.10-0.13 mm long. Labrum slightly longer than head is high. Mesoscutum dark reddish brown to blackish brown, sublustrous in dorsal view and light grey in frontal view. Legs mostly paler than in male: fore coxa yellow to brownish yellow, also proximal parts of all femora mostly yellowish brown. Setation of legs as in male, only mid tibia sometimes with 1-2 setae dorsally not longer than tibia is deep. Measurements (in 0.01 mm scale): length: f1 (78-86), f2 (90-96), f3 (120-136), t1 (80-87), t2 (80-91), t3 (111-120), bt1 (37-43), bt2 (34-36), bt3 (47-50), width: bt1 and bt2 (3-4), bt3 (5). Wing almost clear, stigma slightly darkened, M2/D = 1.6-1.9, CuA1 ratio = 2.3-3.8, lw: ww = 2.6-2.9. Abdomen mostly yellowish brown proximally and dark blackish brown distally, microtrichose, lateral part of tergites 3-4 sublustrous. Hind marginal setae on sides of tergites 2-3 up to 2/3 as long as their corresponding segments, on remaining segments shorter, discal setae shorter than marginals. Length of body 2.8-3.5 mm, wing 2.9-3.3 mm.

DIFFERENTIAL DIAGNOSIS: R. (Holoclera) bohemica sp. n. belongs to the R. (Holoclera) nigripennis group and it is most similar to R.­ nigripennis and R.­ helvetica sp. n. (all three having supraalar seta absent and front coxa usually paler than pleura). However, male cercus ( Fig. 2 ) is more similar to R.­ trigemina Oldenberg ( Fig. 9 , i.e. deeply concave dorsally) than to R.­ nigripennis (Fabricius) . Moreover, the species described above has a relatively short 3 rd antennal segment in comparison to all other species of R.­ nigripennis group and this is probably the only characteristic enabling differentiation between females of R.­ bohemica and R.­ helvetica .

DERIVATIO NOMINIS: the specific name is derived from the country of origin

( Bohemia = historical part of the Czech Republic).
