Geostiba (Sibiota) articarinata ASSING, 2016 ( Figs 12-14 )

M a t e r i a l e x a m i n e d: Russia: 1♂, 1♀, Adygeia, 14 km NE Mt. Fisht, Lagonaki Plateau , 1700 m, 16.VI.1999, leg. Smetana (cAss) ; 1♀, Adygeia, 12 km NE Mt. Fisht, Lagonaki Plateau , 1800 m, debris along the edges of a snow field sifted, 14.VI.1999, leg. Smetana (cAss) .

C o m m e n t: The original description is based on a unique male ( ASSING 2016a). The above material was collected close to the type locality. Based on the shape of the spermatheca, the morphology of the aedeagus, and the shape of the male tergite VIII (posterior margin broadly and deeply concave), G. articarinata is most closely allied to G. krzysztofi ROUBAL, 1913, not to G. convergens ASSING, 2011 as suggested by ASSING (2016a). The previously unknown female sexual characters and the aedeagus of the above male are illustrated in Figs 12-14 .
