Diagnosis
This new species most closely resembles S. multidontata ( Qu, Peng & Yin, 2010) ( Figs 4–5 View Fig View Fig ), but differs from the latter by the following characters. Lateral projection of the median apophysis with a blunt end, slightly touching lateral edge of cymbium in the new species ( Figs 1C–D View Fig , 2A–B View Fig , 3C–F View Fig ), whereas distal end truncate, almost overlapping lateral edge of cymbium in ventral view in S. multidontata ( Figs 4A– B View Fig , 5C–F View Fig ). Septum wider than long and spermathecal heads spherical with fine spermathecal stalks in the new species ( Figs 2C–D View Fig , 3G–H View Fig ), whereas septum longer than wide and spermathecal heads oval with thick spermathecal stalks in S. multidontata ( Figs 4C–D View Fig , 5G–H View Fig ).
Etymology
The specific epithet refers to the type locality ‘Medog’ (‘Ḅü’ in Chinese); noun in apposition.
