  • Dorsal surface of head behind eyes mostly smooth, or nearly so, with scattered punctures, though sometimes with a roughened area along the extreme posterior margin; sculpture of rest of the body as least partly different from that described from ‘’’sylvicola’’’. Colour black to ferruginous . . . . . 5


return to couplet #4

  • Petiole and postpetiole both with coarse, contiguous and confluent punctures, overlain in large part by punctulate-granulose microsculpture that renders the surface prevailingly opaque. Colour dark reddish brown ….. Parasyscia lamborni

  • Petiole and postpetiole, or at least one of the two segments, with separate punctures, the interspaces smooth and shining ….. ‘’’cribrinodis’’’ group (text in parenthesis reflects notes [30] on the reference)
