Holohalaelurus favus: Human, 2006b: 36, figs. 11–12; Human, 2010: 25; Ebert, 2013: 182, fig. 244; Ebert et al., 2013 a: 358, fig., pl. 48; Ebert & Mostada, 2013: 62, fig.; da Silva et al., 2015: 248; Ebert & van Hees, 2015: 147; Weigmann, 2016: 877.
South Africa voucher material: Holotype: SAIAB [former RUSI] 6139. Paratype: SAIAB 6138.
South African distribution: From Durban to the KZN border with Mozambique.
Remarks: A near endemic with a very limited range of about five degrees latitude from about off Durban (KZN) to just northeast of Maputo, Mozambique (Human, 2006b). This species is of serious conservation concern since a single record from 2007 represents the only contemporary record despite its range being subject to surveys (Pollom et al., 2020).
Conservation status: EN (2020).
