MATERIAL EXAMINED. Russia: Primorskii krai, environs of Vladivostok, Botanical garden , 43°13' N, 131°58' E, summer 2010, 1♂, coll. V.M. Loktionov, S.A. Shabalin ( ZMMU) ; Ussuriyskii District, Kamenushka vill., 43°36.45' N, 132°13.60' E, 29.VIII 2001, 10♀, coll. G.N. Azarkina, Y.M. Marusik ( ZMMU, ISEA) .

NOTES. This species was described based on the holotype male from Liaoning Province, China, and the female of this species was unknown until our discovery. Wunderlich & Li (1995) doubted that this species belong to Oreonetides Strand, 1901 . It is smaller than other species (1.4–1.5 mm, whereas other Oreonetides species are longer than 1.6 mm) and has a long, filamentous embolus ( Figs 19, 20 ), unknown in other Micronetinae . Here we provide diagnostic figures of the poorly known male ( Figs 10, 13,14 , 15–20 ) and previously unknown female ( Figs 11, 12 , 21–23 ).

The discovery of the female and study of the embolic division of the male still do not allow correct taxonomic placement of this species. On one hand, the epigyne ( Figs 12 , 21, 22 ) is characteristic of Maro O. Pickard-Cambridge, 1906 , with the triangular epigynal plate (cf. Saaristo, 1971; Eskov, 1991; Tanasevitch, 2006), but on the other hand, it lacks the posterior median plate characteristic of illustrated Maro species ( Eskov, 1991; Tanasevitch, 2006). The paracymbium ( Figs 15, 18 ) looks like that found in Oreonetides and has a ventral triangular outgrowth (To) as in O. vaginatus (Thorell, 1 8 7 2) and other congeners (cf. Eskov, 1 9 9 1). This outgrowth is lacking in Maro (cf. Saaristo, 1971; Tanasevitch, 2006). There are several other characters indicating close relationships with either Oreonetides or Maro , but the shape of the embolic division ( Figs 19, 20 ) and particularly the embolus (Em) is unique for Micronetinae . All other Micronetinae (cf. Marusik & Koponen, 2008: Plates 1-4) genera have a membranous embolus, but O. longembolus has a long, whiplike embolus. Most likely this species should be attributed to a separate genus
