Two new species and additional data of Gabrius Stephens (Coleoptera, Staphylinidae) from the Korean Peninsula Author Schillhammer, Harald text Zootaxa 2015 3936 3 446 450 journal article 10.11646/zootaxa.3936.3.10 61062d56-2d9b-4f53-aca4-6d26a79dfec8 1175-5326 236243 A019200F-65F6-42FF-974C-274BD1213A2C Gabrius makranczyi sp. n. Holotype ♂: “S-KOREA, Jeollanam-do, Jiri-san, around Nogodan peak, rocky slope at tourist trail with bushes, 1500 m \ soil washing, 20 cm deep at rock base under tree (24B), 35°17’36”N , 127°31’55”E , 15.IX.2010 , Makranczy et al. ” (TMB).— Paratypes : 1 ♂ , with same data as holotype ( NMW ); 1 ♂ : N-KOREA: “ KOREA , no. 692, Kangwon Prov., Mts. Kumgang-san, singled, 18.IX.1980 , leg. Tópal & Forró” (TMB). Diagnosis . 5.9–6.3 mm long ( 3.1 mm , abdomen excluded). The diagnosis is based on the holotype , differences in the paratypes are mentioned separately. The species hardly differs from G . koreanus both in shape and coloration; head more quadrangular, tempora straight, subparallel, 1.7 times as long as eyes, punctation of elytra slightly denser. Aedeagus ( Fig. 2 ) with apical portion of median lobe similar to that of G . koreanus , but sides bisinuate and less distinctly narrowed towards apex; in lateral view ( Fig. 2 b) with apical portion markedly bent dorsad, especially the sharply pointed apex. Paramere ( Figs 2 c, d) hardly widened distally, with a much narrower apical emargination; peg setae similarly arranged but more numerous, basad reaching almost base of apical portion of paramere; apical margin bearing the same thick setae as in G . koreanus , smaller setae situated almost at base of apical portion of paramere. Female unknown. Variability . The slightly teneral paratype from South Korea looks somewhat different from the syntopic holotype : head more distinctly rounded, tempora slightly convex, slightly widened posteriad, sides of pronotum distinctly convex. Paramere ( Fig. 2 c) with deeper and somewhat narrower apical emargination. Experience has shown that, despite the interspecific similarity, Gabrius species exhibit a sometimes remarkable intraspecific variability (e.g. Gabrius astutus group). Therefore, I have no doubt that the above mentioned paratype is conspecific with the holotype . Systematic position . This and the previous species share some characters with the Gabrius osseticus group and to some extent also with the Gabrius femoralis group, in particular the shape of the male sternite VIII with extensive semimembranous extension, but also the shape of the paramere. However, the large apical setae of the paramere, which are small or not even developed in those groups, would render the two new species rather strange elements. I will refrain from introducing another species group name until the relationships among Gabrius species are better understood. Distribution . The species is at present known from one locality each in North and South Korea . Etymology . The species is named after György Makranczy (Budapest), specialist in Oxytelinae , who collected most specimens of both new species.
