Cryptochloris zyli Shortridge & Carter, 1938:284

Van Zyl's golden mole

Taxonomy & Nomenclature

Synonym/s: Cryptochloris wintoni zyli Shortridge & Carter, 1938:284

Taxonomic history

Originally described as a full species (Cryptochloris zyli) by (Shortridge & Carter, 1938:284), it was reduced to a subspecies of Winton's golden mole (Cryptochloris wintoni zyli) by (Ellerman et al., 1953) and retained as a subspecies by (Simonetta, 1968:40), before being re-elevated to full species status by (Meester, 1974). It has been treated as a valid species by most authors in recent decades (Meester et al., 1986; Skinner & Smithers 1990; Hutterer 1993; Nowak 1999; Bronner & Jenkins, 2005; Skinner & Chimimba, 2005; Bronner, 2008, 2013, 2015; Taylor et al., 2018).

Generic placement

"Recent (but still unpublished) phylogenetic analyses based on both morphological and genetic data support the allocation of these taxa to separate species, and justify synonymizing Cryptochloris as a subgenus of Chrysochloris, corroborating the close phylogenetic association of these taxa reported by Asher et al. (2010)."

(Bronner, 2015)

Conservation Status

Last record: 28 March 1938 (Helgen & Wilson, 2001:111)

Rediscovered in November 2003

IUCN RedList status: Endangered

Three specimens were collected from the type locality (Compagnies Drift, Western Cape Province) in 1937-1938 (viz. 13 January 1937, January 1938, 28 March 1938) (Helgen & Wilson, 2001:111), before the species was rediscovered 150km north in November 2003 at Groenriviermond, Northern Cape Province (Bronner, 2015).
