( Figs 1–3 , 23 , 47–49 ) Type material . HOLOTYPE ♂, labelled: “ PORTUGAL : Campo (Valongo) [ 42°10′04” N 8°29’41”W ], 30.vi.2010 (leg. R. Andrade)” ( RBINS ). PARATYPES : 1 ♀, same data as holotype ( RBINS ); 1 ♀, same locality as holotype , 28.vii.2010 , leg. R. Andrade ( RBINS ). Recognition . Scutum with 4 shining vittae on a grey background; legs extensively yellow, hind coxa, trochanter and femur black, hind tibia brown; wing with cells br and bm lacking microtrichia. Description . Male ( Fig. 23 ). Wing length 3.5–3.7 mm. Head black. Occiput densely greyish pollinose, with yellow to pale setae. Ocellar tubercle with 2 moderately long fine anterior ocellars and 2 minute posterior ocellars. Antenna black. Proboscis dark brown. Palpus black, as long as labrum; with scattered short black setae. Thorax black in ground-colour; largely greyish pollinose, scutum with 4 shining vittae; with pale to yellow setation. Proepisternum with 1 long fine upturned seta. Antepronotum with several short fine setae. Postpronotal lobe with several short fine setae (one somewhat longer). Mesonotum with 2 notopleurals (posterior seta longer), 1 postalar and 2 scutellars (with several short pale hair-like setae); supra-alar space with short fine setae; acrostichals arranged in 2–3 irregular rows, longer posteriorly, lacking on prescutellar depression; dorsocentrals mostly uniserial, fine, short; 1 pair of prescutellars long. Legs with hind coxa, trochanter and femur black, fore and mid coxae, hind tibia (paler toward apex), fore and mid tarsomeres 1–3 and hind tarsomere 5 brown, otherwise legs yellow; shining, except coxae. Coxae and trochanters with pale setae of different lengths. Fore femur with rows of pale fine anteroventral and posteroventral setae (nearly as long as width of femur). Fore tibia with 1 short dorsal brownish bristle on about apical 1/3rd, clothed in long pale hair-like setae posteriorly and ventrally; subapical circlet formed by several fine yellow setae of different lengths. Fore basitarsus with several short, black subapical setae ventrally, clothed in long, pale hairlike setae dorsally and laterally. Mid femur somewhat narrower than fore femur, with similar setation to fore femur, no strong anterodorsal bristles. Mid tibia with 2 rather short, brownish anterodorsal bristles, clothed in pale hairlike setae, no strong anteroventral bristles; subapical circlet including 2 long yellow bristles ventrally. Mid basitarsus with yellow spinule-like setae ventrally and several similar black setae subapically. Hind femur strongly thickened, clothed in numerous long, pale hair-like setae; with two complete rows of short ventral spines and 3 longer anteroventral spines closer to apex. Hind tibia thickened, clothed in long, pale hair-like setae. Hind tarsomere 1 with several black spines ventrally; tarsomere 2 with 1 similar subapical spine. Wing hyaline; veins yellowish brown; no costal bristle; stigma indistinct, elongate-ovate; R1 close to costa subapically; R4+5 and M1+2 parallel near wing margin; costal br and bm cells lacking microtrichia. Squama yellow, with pale setae. Halter yellow. Abdomen black in ground-colour, finely greyish pollinose, covered with pale fine setae, longer on tergites laterally and on sternites. Terminalia ( Figs 1–3 ) black, large. Cerci small, with some scattered short setae. Right epandrial lamella subtriangular viewed dorsally ( Fig. 2 ), with numerous moderately long to short setae; right surstylus small, rather trapezoidal (dorsal view), with some short marginal setae. Left epandrial lamella with several very long setae on apical part; left surstylus short, subtriangular, with several short marginal setae. Hypandrium ( Fig. 1 ) long, elongate ovate, narrowed apically, with some moderately long to long bristles on apical half. Female . Similar to male but fore and mid tibiae and tarsomeres 1 covered with shorter hair-like setae. Postpedicel with 1 short dorsal seta. Abdomen conical; tergite 7 unmodified, smaller than tergite 6, with straight posterior margin, minute posteromarginal setae; sternite 7 broader than sternite 6, with straight posterior margin, with several long hair-like setae; segment 8 rather elongate, well exposed; tergite 8 with anterior margin entirely encircling abdomen (ring-like) and strongly sclerotised, dark brown, without setation on venter ( Figs 48, 49 ); posterior part of tergite 8 yellowish brown, with straight margin, covered with numerous short setae; sternite 8 separated from tergite 8, ovoid, undivided, covered with numerous short setae; tergite 10 very weakly sclerotised, separated from both sternite 10 and cerci, divided along midline; sternite 10 entire; cercus short, egg-shaped, brown. Etymology . The new species is named in honour of Rui Andrade (Barcelos, Portugal ) who collected the type series. Distribution . PALAEARCTIC: Portugal ( Fig. 47 ). Remarks . Hybos andradei sp. nov. is closely related to H. mediasiaticus sp. nov. from Middle Asia described below. Both species bear four shining scutal vittae, distinguishing them from H. femoratus (scutum largely shining). Hybos andradei sp. nov. differs from H. mediasiaticus sp. nov. by the lack of microtrichia on cells br and bm of the wing and by some other characters.
