Differential diagnosis
This new species most resembles S. nigrum sp. nov., although it can be distinguished by the merely infuscate apical area of the fore wing (with a distinct apical mark in S. nigrum sp. nov.). Although S. pseudonigrum sp. nov. and S. nigrum sp. nov. are difficult to distinguish from each other, they are distinct by molecular analysis ( Fig. 9 View Fig ); the genetic distance between them was about 9.8 %. This species also resembles S. brachyurum sp. nov., but it has a square area superomedia of the propodeum (the area is rounded in S. brachyurum sp. nov.).
Description
Female (n = 27).
BODY LENGTH. 6.5–9.5 mm.
HEAD. Vertex 0.4 times as long as maximum length of eye in dorsal view. Frons without a depression between eye and antennal socket in frontal view ( Fig. 2h View Fig ).
