diagnosis
Diagnosis. Dorsal-fin rays VII-I, 9; pectoral-fin rays 16 – 18; total gill rakers 29 – 33; vertebrae 11 + 14; pyloric caeca 6 – 7; pored lateral-line scales 46 – 50 + 3 – 5; pungent opercular spine present; blunt maxillary mustache-like processes present; ribs on last abdominal vertebra present; tongue toothless; two nub-like structures present on symphysis of lower jaw.
distribution
Distribution. South Indian Ocean (Mayer 1974; Gon 1986; Parin & Abramov 1986 b; Abramov 1992); Australia (Hoese et al. 2006; Gomon et al. 2008); New Zealand (Paulin et al. 1989; Stewart & Gon 2015); and western South Atlantic (Nakamura 1986; Abramov 1992), at 500 – 1700 m depth. Comparisons and Remarks. Epigonus robustus is a member of the E. constanciae group by having a pungent opercular spine (Fig. 17 A). The species is similar to E. lenimen in having 11 + 14 vertebra; however, it differs from E. lenimen by having two nub-like structures on the symphysis of lower jaw (vs. absent in E. lenimen) and the orbital diameter shorter than postorbital length (vs. orbital diameter longer than postorbital length in E. lenimen). The other five species of the group in the Western Indian Ocean, E. bispinosus, E. idai, E. marimonticolus, E. pectinifer, and E. waltersensis, have 10 + 15 vertebrae (vs. 11 + 14 vertebrae in E. robustus). Several years ago, the second author examined the holotype, or rather what of left of it (Fig. 17 C). The specimen was collected on 20 August 1903 during marine surveys conducted in the period 1897 – 1904 by the Pieter Faure, the Government steam trawler, under the leadership of J. D. F. Gilchrist who was then Director of the Government’s Marine Biological Survey as well as Honorary Keeper of the Department of Marine Invertebrates of the South African Museum, Cape Town (Gon & Skelton 1997). In addition to the parts of the fish shown in Fig. 17 C, the jar of SAM 13080 contains scattered bones and scales of the specimens.
