Current status.

Cornisepta onychoides (Herbert & Kilburn, 1986); McLean and Geiger (1998); Herbert (2015).

Remarks.

One paratype (T3085/ NMSA-MOL 0D1421) was sent to Zoological Museum of Moscow University in 1990. Two, of supposedly eight, paratypes (T3084/ NMSA-MOL 0D1312) have been sent to NHMUK (registration number: NHMUK 1986088) and one from the same lot, - to Humboldt University, Berlin (however, probably due to initial miscount, only four, not five, remain in NMSA).
