Betiscoides sjostedti Key, 1937

Remarks.

The specimen of DEL 8 from Cape Point, Table Mountain NP, is hereby considered as Betiscoides sjostedti as it coincides with its overall morphological diagnostic characters. The intermediate body size, the almost equal length of the antennae and head, the fastigium about 2/3 the length of the eye, as well as the comparatively short subgenital plate, reason this allocation. In order to assess the hairiness, the specimen of DEL 8 was compared with images of the holotype (male, NHMUK, Table Mountain, South Africa, December 1929-1930), both showed fairly smooth integument. This specimen occurs in sympatry with specimens from DEL 3. In order to assess the female genital characters, I analyzed images of the allotype (female, NHMUK, Table Mountain, South Africa, December 1929-1930).
