Type locality. RSA, WC: Knysna Forest.

Remarks. In sample ‘ Type 355 SAMC’ there are fragments of a specimen from ‘ ex typis A. sclateri sp. inquir.’ ( Pickford 1937: 259). BMNH 1938.7.1.1009 contains fragments of Michaelsen’s material enriched by pieces from the specimen collected by Pickford (according to two labels inserted in the jar and notes drawn on the jar). Pickford (1937: 259) examined fragments of Chilota knysnanus Michaelsen, 1913 (into which fragments of Acanthodrilus sclateri type specimen had been included by Michaelsen) together with a semi-mature specimen collected by herself in the vicinity of the type locality of Ch. knysnanus , and she re-assigned the studied material as Parachilota knysnanus Michaelsen, 1913 . Pickford described species characters observed on the semi-mature specimen collected by her in the vicinity of knysnanus type locality. Considering that the characters described by Pickford (1937: 259–262; dimensions, shape of spermatheca and its diverticulum, penial setae ornamentation) were taken from the new specimen or from fragments of the original and mixed material, the taxonomic status of knysnanus remains uncertain. Re-examination (possibly by other than conventional methods) of all existing type material, and examination, if possible, of some new material collected at the type locality, would be necessary to revalidate the species.
