Two new species of the genus Leenurina Najt & Weiner, 1992 (Collembola, Neanuridae, Caputanurininae) from Primorskij Kraj (Russia)

Leenurina khualaza sp. n. and Leenurina pomorskii sp. n., two new species from East Russia (Primorskij Kraj) are described. They are closely related to Leenurina jasii Najt & Weiner, 1992 from North Korea, from which they differ mainly in the number of tibiotarsal chaetae (19, 19, 18 in the new species versus 18, 18, 17 in Leenurina jasii), several chaetotaxic features and organization of dorsal granulation. The two new species may be separated by tertiary granulation (large areas fringed with large secondary granules in L. pomorskii, small rounded or hexagonal areas with smaller secondary granules in L. khualaza), coloration (light blue in L. khualaza versus white in L. pomorskii) and number of eyes (2+2 eyes in L. khualaza versus 3+3 eyes in L. pomorskii). An updated diagnosis of the genus Leenurina Najt & Weiner, 1992 and a key to species of Caputanurininae are given
