"Chlamydoselachus africana, a new species of frilled shark from southern Africa
(Chondrichthyes, Hexanchiformes, Chlamydoselachidae)"
Frilled sharks (Chondrichthyes, Hexanchiformes, Chlamydoselachidae), long
believed to be a monotypic family and genus, consisting of a single wide
ranging species, Chlamydoselachus anguineus (Garman, 1884), is now known to
contain at least two species. A new species of frilled shark,
Chlamydoselachus africana, sp. nov., is described from five specimens
collected from southern Africa. The new species, although difficult to
distinguish externally from the well known C. anguineus, differ internally
by the structural differences in the chondrocranium, lower total vertebral
and spiral valve counts, and pectoral-fin radial counts. The new species,
Chlamydoselachus africana, is known from off southern Angola, Namibia, and
Zootaxa 2173: 1–18 (2009).
