Introduction
Bicellaria Macquart, 1823, type species: Bicellaria nigra Macquart, 1823 [= B. spuria (FallÈn, 1816)] is a middlesized mostly Holarctic genus of Hybotidae with 38 described species or subspecies; 27 of them are Palaearctic and 11 are Nearctic (BartÀk & KubÌk 2013). In this paper, an additional 10 species from Asia are described (one of them from the Oriental Region). Asian species of Bicellaria are very poorly known. Tuomikoski (1955) described B. stackelbergi from Kanin (North of European Russia), Siberia (Yakutsk, Altai) and Kamchatka, and reported B. vana Collin, 1926 (as subspecies) from Yakutsk, B. subpilosa Collin, 1926 from the Caucasus, and B. uvens Melander, 1928 (as B. bisetosa Tuomikoski, 1936; B. bisetosa was proposed as a junior synonym of B. uvens by BartÀk & KubÌk 2013) from the Russian Far East but it is unclear if all these species were correctly identified. Collin (1960) described additional species (B. femorata) and subspecies (B. spuria ingrata) from Palestine (now Israel). Kato (1971) described three species from Japan; however, we found that one of his species (B. montana) was identical with B. uvens and propose a formal synonymy here. Other authors have not attempted to identify Asian Bicellaria to species level: Smith (1965) reported one species from Nepal and indicated it could be B. vana, ChvÀla (1983) reported one undescribed species close to B. spuria from Kazakhstan, and Bezzi (1912) from Formosa (= Taiwan) (doubtfully B. spuria).

Material and methods
The material studied is deposited in the following collections: CNC (Canadian National Collection of Insects and Arachnids, Ottawa), CULSP (Czech University of Life Sciences, Prague); NHMH (Natural History Museum, Helsinki); NMWC (National Museum of Wales, Cardiff), QSBG (Entomology Museum, Queen Sirikit Botanic Garden, Chiang Mai, Thailand), TAU (Tel Aviv University Entomological collection, Israel), ZMMU (Zoological Museum of Moscow State University, Russia). Genitalia, together with the preceding 2­3 abdominal segments were removed from the rest of the body using small scissors and macerated in potassium hydroxide solution (approx. 10 %) in small vials submerged in hot water

for 1­2 hours. After neutralizing with acetic acid, the genitalia were dissected in glycerine and the parts (hypandrium from ventral side, postgonites with phallic apparatus) were photographed using an ®Olympus E-410 digital camera mounted on an ®Olympus BX51 compound microscope and images were edited with the computer software Quick Foto micro 2.3 provided with deep focus 3.1. Final images were a montage composed usually of 7­ 15 layers and were further edited with ®Microsoft Office Picture Manager, and served as models for hand drawn illustrations; details were added observing genitalia under a stereoscopic microscope. The morphological terms used here follow Merz and Haenni (2000), Sinclair (2000), and Sinclair and Cumming (2006). Structures of the terminalia are explained in BartÀk and KubÌk (2013). All body measurements (including body and setae length) were taken from dry specimens (therefore the actual length may differ from that of fresh or wet-preserved material) by means of an ocular micrometer mounted on Nikon SMZ 1500 binocular microscope. Male body length was measured from antennal base to the tip of genitalia and female body length from base of antennae to the tip of cerci. Terms "left" and "right" (e.g., right postgonite, left phallic hook) refer to sagittal plane viewing the animal from above. Thoracic setae are counted on one side of body (i.e. "7 acrostichals" means 7 in a single row) except scutellars. Locality names in Israel were transliterated according to official map of Israel (Israel Touring Map, 1:250,000, 2009) and "List of Settlements", published by the Survey of Israel, Ministry of Labour.

Diagnosis. Species of the genus are small flies (wing length 1.9~4 mm), brown to dull black with black or pale setae (almost exclusively pale in B. chimganensis sp. nov.). Head hemispherical with prominent ocellar triangle bearing one to two pairs of ocellar setae and short proboscis, palpus with one to ~10 setae. Antenna black, pedicel with circlet of setae, ventral ones often elongated, lateral ones elongated in B. longisetosa ChvÀla, 1991, third segment with one to several elongate dorsal setae situated on proximal part of the segment (B. austriaca complex) or on distal part of the segment (B. dispar Oldenberg, 1920) or without seta(e), apical stylus two-segmented. Face sometimes very narrow (about 0.02 mm), even narrower below (B. vana, B. koreana sp. nov., B. nigra complex), in most species slightly narrowed ventrally, but also broadened ventrally (B. pilosa Lundbeck, 1910). Thorax dull black, more or less arched, conspicuously setose. Acrostichals biserial and distinctly separated from dorsocentrals, setae sometimes long (more than 0.15 mm) but shortened in some species (B. koreana sp. nov., extremely so in B. dispar), taxonomically important but overlooked by previous authors is number of setae in intrahumeral and posthumeral areas (i.e., in presutural area laterad from dorsocentrals). Legs slender, at most hind tibia at least slightly swollen apically, usually less distinctly so in females. Fore femur usually with sparse rows of short anteroand posteroventral setae; fore tibia with species-specific ciliation on ventral part in distal third: some species bearing pilosity similar to that of fore basitarsus but absent or very short in other species and posteroventral setae very short, absent or distinctly longer than diameter of tibia in other species (usually short posteroventral setae found in species with long pilosity--typical feature of B. sulcata and B. nigra complexes). Mid femur usually with very short anteroventrals (somewhat longer in B. setitibia sp. nov.) and longer posteroventrals. Mid tibia usually with one to several dorsal pairs of setae situated on basal two-thirds, in B. setitibia sp. nov. with long setae also on apical part. Hind femur usually with two rows of elongate setae anterodorsally and anteroventrally, posteroventrals usually much shorter or (rarely) absent. Hind tibia mostly swollen in males and less so in females, but sometimes almost clavate [B. stackelbergi, B. sulcata (Zetterstedt, 1842)] or narrow and not at all swollen [B. simplicipes (Zetterstedt, 1842)], hind tibia with long and strong apical setae in B. woodi sp. nov. Wing usually at least slightly darkened, cell dm absent, base of vein M often depigmented, vein A1 reaching (or nearly so) hind wing margin, area between tip of veins Sc and R1 stigma-like darkened. Abdomen elongate and narrow, in males usually darker

in dorsal view and lighter in lateral view. A detailed description of the male genitalia was given by BartÀk and KubÌk (2013) and the following presents a more detailed comparison with respect to Asian fauna. Male genitalia usually small (somewhat larger and almost globular in B. globulicauda sp. nov.). Epandrium, cerci and hypoproct usually very similar between species, apparently without useful diagnostic features (except B. globulicauda sp. nov. with swollen epandrium). Hypandrium usually with two processes (absent in B. farkaci sp. nov. or with additional rounded process between processes in one unidentified specimen from Georgia), in most species bearing several moderately long spines near apex, but also long setose along its length (B. femorata Collin, 1960, B. japonica Kato, 1971). Shape of hypandrial processes very important: in several species processes long and narrow (e.g., B. koreana sp. nov.), or contrastingly short and broad (B. uvens), or long and broad (B. shatalkini sp. nov.). Hypandrium articulates dorsally with symmetrical postgonites (slightly asymmetrical in B. chimganensis sp. nov.), mostly roughly rectangular or trapezoid in lateral view, sometimes short (B. shatalkini sp. nov.) or elongate (B. kovalevi sp. nov.), triangular or broadened laterally (narrow in lateral view in B. uvens), precise shape of postgonites species-specific. Left and right postgonites connected dorsally; middle connected part articulates closely with phallic hooks. Phallus membranous in most species, in B. longisetosa dorsal side sclerotized forming roof-like flat sclerite. The structure of the phallic hooks provides many important differentiating characters. Usually two phallic hooks are developed and sometimes the right one is reduced, although in B. setitibia the left one is reduced (see remarks under the species). Species of B. pilosa-complex have three phallic hooks (left hook bifurcate, extremely so in B. femorata, Fig. 7). Female terminal segments at least 8th sternite nearly always shining (except B. farkaci sp. nov.), and basal part of tergite 8 shining in most species (often also basal parts of tergites 6­7, but dry specimens often hidden under preceding tergites); rarely (B. amankutanensis sp. nov.) tergites 5­8 and sternites 6­8 also shining.

posteroventrals slightly shorter than depth of femur. Mid tibia with 1­2 pairs of setae dorsally in basal half up to twice as long as depth of tibia, otherwise short setose. Hind femur with 15­20 anterodorsal setae on basal third up to 2X as long as depth of femur, much shorter apically and with row of 16­22 anteroventrals slightly longer than depth of femur at about middle and shorter both basally and apically, posteroventrals half as long as depth of femur. Hind tibia swollen in apical part (0.14­0.16 mm at broadest point in comparison with 0.06 mm in basal part), several anterodorsals and posterodorsals up to 0.20 mm long, ventral setae short. Tarsi of all legs thin, short setose, basitarsus of hind leg very slightly swollen (0.09 mm). Wing slightly yellow-brownish infuscated; stigma brown, long (0.70 mm), almost parallel-sided and narrow (0.05 mm), narrower than cell r1 (about 0.09 mm broad at narrowest point). Distance between tips of veins R1 and R2+3 about 0.30 mm. Squama yellowish with pale fringes, halter clear yellow. Abdomen blackish-brown in ground-colour, brown in dorsal view and pale grey in lateral view, microtrichose, pale setose, dorsally with short setae, posteromarginals on sides of tergites as long as or slightly longer than corresponding segments. Genitalia (Figs 3, 4) with hypandrial processes medium long and narrow, with conspicuous but not very long spine at tip; postgonites elongate-trapezoid, slightly asymmetrical (right one slightly longer and broader at apex); left phallic hook long, right one strongly reduced. Female mesoscutal setae less numerous and hind tibia narrower (0.11 mm) than in male. Tergites 5­8 polished, sternites 5­8 polished (5th sternite with narrow sparsely microtrichose central stripe), other parts of abdomen microtrichose. Length: body 2.2­3.0 mm, wing 2.3­3.0 mm. Remarks. Bicellaria chimganensis sp. nov. can be easily recognized from all other Palaearctic species of Bicellaria by its mostly pale setose body (including all mesoscutal setae) and narrow hind basitarsus. Moreover, females have the last four sternites polished. Bicellaria amankutanensis sp. nov. is undoubtedly closely allied with this species. Beside the main diagnostic character given in the key (different colouring of mesoscutal setae), the species described above has slightly smaller broad part of third antennal segment, less setae on the intrahumeral and posthumeral areas and more sparsely microtrichose mesoscutum giving it a subshining appearance. The genitalia of both species are very similar, B. chimganensis sp. nov. has slightly narrower hypandrial processes. Female 5th sternite is polished in B. chimganensis sp. nov. with the exception of sparsely microtrichose central stripe but is densely microtrichose (with the exception of narrow polished lateral parts) in B. amankutanensis sp. nov.

pleura, antepronotum and sternites without any setae. Legs including coxae black, microtrichose and black setose. Fore femur with row of very short anteroventrals and row of longer posteroventrals (slightly shorter than depth of femur). Fore tibia with 0­2 dorsal and 0­1 submedian posterodorsal setae about 1.5X as long as depth of tibia, otherwise short setose, posteroventrals in apical third about as long as depth of tibia, pilosity apparently absent (similar to B. spuria); conspicuous anteroventral sense organ ovoid, about 0.10 mm long, consisting of central area of very short hairs and surrounding ovoid circle devoid of microtrichiae. Mid femur with sparse row of anteroventrals one-third as long as depth of femur and with much stronger and longer posteroventrals slightly longer than depth of femur. Mid tibia with 2 anterodorsal (1 subbasal and 1 submedian) and 1 submedian posterodorsal setae 2X as long as depth of tibia and 2 ventral preapical setae. Hind femur with 15­17 anterodorsal setae on basal third slightly longer than depth of femur, with row of 18­20 anteroventrals about as long as depth of femur, much shorter posteroventrals absent on apical half to third. Hind tibia very slightly swollen in apical part (0.12 mm at broadest point in comparison with 0.08 mm in basal part) being much narrower than hind femur (0.18 mm at broadest point), both dorsal and ventral setae slightly longer than depth of tibia, several anterodorsals up to 0.20 mm long. Tarsi of all legs slender, short setose. Wing slightly brownish infuscated; stigma dark brown, long (0.80 mm), almost parallel-sided and narrow (0.05 mm), much narrower than cell r1 (about 0.13 mm broad at narrowest point). Distance between tips of veins R1 and R2+3 about 0.40 mm. Squama dark brown, halter dark brown. Abdomen brown, microtrichose, entirely black setose, dorsally with short setae, marginals on sides of tergites 2­5 slightly longer than corresponding segments, on subsequent tergites slightly shorter. Genitalia (Figs 5, 6) with hypandrial processes absent, distal part of hypandrium with some 5 long setae on each half; postgonites triangle-shaped, two nearly identical phallic hooks present. Female. Tergites entirely pruinose, sternite 8 microtrichose on apical (visible) half, polished on basal half. Length: body 2.7­3.5 mm, wing 3.2­4.0 mm. Remarks. All specimens of the type series are rather damaged, devoid of most mesoscutal setae; however, their arrangement, number and length may be judged from their articulations and several setae present on some specimens. The new species is quite different from all known species of Bicellaria in having hypandrium rounded caudally, without processes. Also the combination of setose palpus with third antennal segment lacking long dorsal setae is not present in any known species and the microtrichose female 8th abdominal sternite is also a very peculiar feature. According to all these characters this species is easily recognizable from all other species of Bicellaria worldwide.

Bicellaria femorata Collin (Figs 7, 8)
Bicellaria femorata Collin, 1960: 392.

Identification of syntypes. Bicellaria femorata was described from five specimens: "a male labelled "Jerusalem [=Yerushalayim], O. Theodor", and a female "Ginegar, Gallilee, 10.xi.[sic!]34. O. Theodor". Also two females from "B. Alta [= Bet Alfa], 16.i.40, Dr. A. Shulov", and one from "Judean Hills, 1.ii.31. O. Theodore" [sic!]". All the above specimens are present in TAU: 1 male labelled "Jerusalem Palestine [=Yerushalayim] O. Theodor / COM. INST. ENT. COLL. No. 12611 / TYPE / B. femorata det. Coll. 58", 1 female labelled "G 10 1 / Ginegar Galilee Palestine O. Theodor 10.ii.34 / COM. INST. ENT. COLL. No. 12611 / B. femorata det. Coll. 58", 1 female labelled "B. Alfa 16.i.40 / 135 / Palestine Dr. A. Shulov / B. femorata det. Coll. 56 / Bicellaria femorata n. sp.", 1 female labelled "B. Alfa [=Bet Alfa] 16.i.40 / 133 / Palestine Dr. A. Shulov / B. femorata det. Coll. 56", and one female labelled "BK VIII 34 / Kir. Anavim [=Qiryat 'Anavim] Judean Hills Palestine O. Theodor 1.2.31 / COM. INST. ENT. COLL. No. 12611 / TYPE / B. femorata det. Coll. 58". We consider all above mentioned specimens syntypes in spite of small difference in date of the female from Ginegar and they were provided by red labels "Syntype Bicellaria femorata rev. BartÀk 2013". Moreover, in TAU there are another two specimens collected before 1960: 1 female without locality labelled "11.i.22 / 5.i.22 / 212" and another female labelled "C J VIII 30 / Jerusalem Palestine [=Yerushalayim] O. Theodor 5.i.36" and another 5 females labelled "Jerusalem Palestine [=Yerushalayim] O. Theodor" which were probably also collected before 1960. These are neither provided with circular handwritten Collin´s identification labels nor listed in the original description. For this reason we identified and labelled as syntypes of both Collin´s species (B. femorata and B. spuria ingrata) only specimens provided by the above mentioned circular label (see also under B. ingrata).

This species was described in full detail by Collin (1960). Bicellaria femorata is included in the B. austriaca-complex of species as defined by ChvÀla (1991), but differs in having a pale halter, long setose hypandrium and swollen and spinose hind femur.
