- Revision of the genus Centrophorus (Squaliformes: Centrophoridae): Part 1-redescription of Centrophorus granulosus (Bloch & Schneider), a senior synonym of C. acus Garman and C. niaukang Teng,
- The genus Centrophorus is one of the most taxonomically complex and confusing elasmobranch groups. A revision of this group is currently underway and this first paper sets an important foundation in this process by redescribing the type species of the genus-Centrophorus granulosus. This taxon name has been previously applied to two different morphotypes: a large species 1.5 m TL and a smaller species ∼1 m TL. Centrophorus acus and C. niaukang are the most commonly used names applied to the larger morphotype. The original description of C. granulosus was based on a large specimen of ∼1.5 m TL, but subsequent redescriptions were based on either of the large or small morphotypes. Centrophorus granulosus is herein redescribed as a large species and a neotype is designated. Centrophorus acus and C. niaukang are found to be junior synonyms of C. granulosus. Centrophorus granulosus is distinguishable from its congeners by its large size, dermal denticle shape, colouration and a number of morphological and biological characteristics. Ontogenetic changes in morphology, dentition and denticle shape for this species are described in detail. © 2013 Magnolia Press., Cited By (since 1996):3, Export Date: 11 February 2014, Source: Scopus, ,

- A new species of deep-sea catshark (Sycliorhinidae: Bythaelurus) from the southwestern Indian Ocean
- Bythaelurus naylori sp. n. is described based on 41 specimens collected from seamounts in the southwestern Indian Ocean. The new species can be separated from all other Bythaelurus species by a combination of distinctly enlarged dermal denticles on the upper caudal-fin margin, lack of papillae on the roof of the mouth and tongue, an anal-fin base length equal to or less than 1.5 times second dorsal-fin base length, and a uniformly plain medium to dark brown body coloration, with light fin edges and a distinct dark dusky-colored snout. No other Bythaelurus species has the combination of a caudal crest of prominent, distinctly enlarged, comb-like dermal denticles along the upper caudal margin and lacks oral papillae. Bythaelurus naylori sp. n. can be distinguished from its two closest cogeners, B. giddingsi and B. lutarius, by a combindation of prominent comb-like dermal denticles along the upper caudal-fin margin, absence of oral papillae, uniform body coloration, and noticeable dark dusky snouth; Bythaelurus giddingsi has oral papillae present and a variegated color pattern, while B. lutarius lacks a caudal crest of enlarged denticles and matures at a much smaller size than the new species.
