Quedius (Raphirus) microcapillatus KORGE, 1971 ( Figs 18-24 , 26-27 , Map 1 )

Quedius (Sauridus) microcapillatus KORGE, 1971b: 16 ff.

T y p e m a t e r i a l e x a m i n e d: Holotype ♂ [dissected prior to present study]: "Azarbaijan ( Iran), Heinz leg. / Danavar-dagh, s.e. Ushnuiyeh, ~ 1600 m, 10.VIII.1969 / ♂ - Holotypus Quedius microcapillatus Korge " (MNB). Paratypes: 1♂, 4♀♀: same data as holotype (MNB).

C o m m e n t: The original description is based on a male holotype and five paratypes from "Danavar-dagh südöstlich Ushnuiyeh" ( KORGE 1971b). A d d i t i o n a l m a t e r i a l e x a m i n e d: Turkey: 1♂, Hakkâri, Hakkâri env., Karakole, river bank, 14.VIII.1969, leg. Heinz ( MNB) ; 1♀, Hakkâri, Dağlıca ["Oramar"], Sat Dağı, 1600-2700 m, 15.VII.1974, leg. Heinz ( MNB). Iraq: 5♂♂, 5♀♀, S Rawandoz, 36°30'N, 44°36'E, 1300-1400 m, pitfall traps, XI.2007 - III.2008, leg. Reuter (cFel, cAss, ZMUC) .

R e d e s c r i p t i o n: Body length 7.0-9.0 mm; length of forebody 3.8-4.5 mm. Habitus as in Fig. 26 . Coloration: head black; pronotum dark-brown to black; elytra brown to black with the humeral angles, the posterior margins, and the suture yellowish to reddish; abdomen brown to black with the posterior margins of tergites III-VI narrowly, the posterior margin of tergite VII broadly, and the posterior portion of tergite VIII

reddish; legs dark-yellowish to pale-reddish; antennae reddish-brown to dark-brown with the basal portions of the basal antennomeres more or less extensively reddish.

Head with fine transverse microsculpture. Pronotum approximately 1.05 times as broad as long and 1.3 times as broad as head; disc, including antero-lateral portions, with fine transverse to oblique microsculpture.

Elytra approximately 0.7 times as long as pronotum; disc with rather dense punctation, but interstices distinctly broader than diameter of punctures; interstices with dense micropunctation visible only at a magnification of at least 100 x ( Fig. 27 ). Hind wings fully developed. Protarsomeres with very weakly pronounced sexual dimorphism. Metatarsomere I approximately as long as the combined length of metatarsomeres II and III.

Abdomen with moderately dense punctation and with extremely fine transverse microsculpture; posterior margin of tergite VII with palisade fringe.

♂: aedeagus ( Figs 18-24 ) 1.1-1.2 mm long; median lobe very slender, apically very acute, and with a ventral tooth practically at apex; paramere approximately 1.0 mm long, very slender, in basal portion constricted (ventral view) and oval in cross-section (i.e., not flattened), apically with two marginal series composed of approximately 20 pegsetae each, these series apically converging and forming clusters rather than series.

C o m p a r a t i v e n o t e s: Quedius microcapillatus is distinguished from the similar Q. hermonensis , with which it was previously confounded ( ASSING 2014), and from the closely related Q. orientalis by the coloration of the elytra (humeral angles, posterior margins, and suture more distinctly and more constantly paler), sparser elytral punctation, and particularly by the presence of micropunctation on the elytra (absent in Q. hermonensis and Q. orientalis ) and the shape of the aedeagus. In Q. hermonensis , the median lobe is less acute (ventral view), the apico-ventral tooth is more pronounced and more distant from the apex of the median lobe, the paramere is basally flat in crosssection and the basal portion of the paramere is weakly constricted at most.

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The currently known distribution is confined to Southeast Anatolia, Northeast Iraq, and Northwest Iran ( Map 1 ). The specimens from Iraq were collected with pitfall traps near a temporary stream.
