Remarks

For Vervoort (1965, p.54) the female of A. Scott's S. farrani is very near to S. helenae, but the lateral margins of the last thoracic somites are of a quite different shape, there is a small difference inthe shape of the crest and P5 are slightly different. The differences in the structure of P5 male are much bigger. The two species are closely allied.
