A new deep-water catshark, Bythaelurus stewarti, is described based on 121 examined specimens caught on the Error Seamount (Mount Error Guyot) in the northwestern Indian Ocean. The new species differs from all congeners in the restricted distribution, a higher spiral valve turn count and in the morphology of the dermal denticles. It is distinguished from its morphologically and geographically closest congener, B. hispidus (Alcock), by the larger size (maximum size 44 vs. 39 cm TL, maturity size… 
Revision of the sixgill sawsharks, genus Pliotrema (Chondrichthyes, Pristiophoriformes), with descriptions of two new species and a redescription of P. warreni Regan
TLDR
The present manuscript contains a redescription of P. warreni involving the syntypes and additional material, as well as formal descriptions of two new species of Pliotrema Regan.
Comparative anatomy of the clasper of catsharks and its phylogenetic implications (Chondrichthyes: Carcharhiniformes: Scyliorhinidae)
TLDR
Almost all catshark genera were examined, described, and illustrated, and comments on their phylogenetic significance are provided and some characters such as degree of development of rhipidions and terminal dermal cover proved to be useful for taxonomic purposes.
Comparative anatomy of the clasper of catsharks and its phylogenetic implications (Chondrichthyes: Carcharhiniformes: Scyliorhinidae)
TLDR
External morphology and skeleton components of claspers vary widely among scyliorhinids and may be useful in phylogenetic analyses and its systematic significance is discussed.
Expanding known global biodiversity of Yamaguticestus (Cestoda: Phyllobothriidea) parasitizing catsharks (Pentanchidae and Scyliorhinidae)
TLDR
The results suggest that the earlier prediction that 70 species of Yamaguticestus remain to be discovered in catsharks across the planet may actually be an underestimate.
Phylogenetic relationship of catshark species of the genus Scyliorhinus (Chondrichthyes, Carcharhiniformes, Scyliorhinidae) based on comparative morphology
TLDR
The monophyly of the subfamily Scyliorhininae is supported as well as of the genus ScylIORhinus, which is proposed to be the sister group of Cephaloscyllium.
Discovery of a new mode of oviparous reproduction in sharks and its evolutionary implications
TLDR
Sarawak swellshark Cephaloscyllium sarawakensis performs a new mode of oviparity, characterized by a lengthy retention of a single egg case in an oviduct until the embryo attains a sizable length, which is correlated with a vivid polka-dot pattern of the embryos.

A new species of deep-sea catshark (Sycliorhinidae: Bythaelurus) from the southwestern Indian Ocean
TLDR
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, and uniformly plain medium to dark brown body coloration.

TLDR
A new deep-water catshark, Bythaelurus bachi, is described based on 44 specimens caught on the southern Madagascar Ridge in the southwestern Indian Ocean and is distinguished from all congeners by the plain beige to light gray-brown coloration, high diversity in dermal denticle morphology, and presence of composite oral papillae.

TLDR
The relationship between reproductive mode and Halaelurus subgenus suggests that aplacental viviparity may have evolved directly from single oviparity in the sub genus Bythaelurus without passing through a multiple oviparous stage.
