TL;DR: Four new species of rare scyliorhinid catsharks are provisionally assigned to the genus Parmaturus : P. lanatus sp.
Abstract: Four new species of rare scyliorhinid catsharks are provisionally assigned to the genus Parmaturus : P. lanatus sp. nov. from Indonesia, P. albimarginatus sp. nov. and P. albipenis sp. nov. from northern New Caledonia, and P. bigus sp. nov. from northeastern Australia. These species differ from each other by a combination of body morphology, denticle shape, dentition, colour and vertebral counts. An identification key to the Indo–Pacific Parmaturus species is provided. Comments on the diagnostic features separating the genera Halaelurus and Parmaturus are given.

TL;DR: Two scyliorhinid catsharks of the genus Halaelurus, H. sellus n.
Abstract: Two scyliorhinid catsharks of the genus Halaelurus, H. sellus n. sp. and H. maculosus n. sp., are described from northwestern Australia and eastern Indonesia, respectively. The new species, which have been confused with H. boesemani (western North Pacific) and H. buergeri (northwestern Indian Ocean), have a colour pattern consisting of dark bars and dark spots but differ from these species by a combination of coloration, morphometrics, and meristics. These species differ from southern African endemics, H. lineatus and H. natalensis, in having a snout tip that is rounded rather than upturned. A related catshark Halaelurus quagga, from the northwestern Indian Ocean, has a colour pattern consisting of more numerous dark bars without spots.

TL;DR: The phylogenetic result showed that H. burgeri did not cluster to the two species of Scyliorhinidae, and the mitogenome contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a longest control region in sharks.
Abstract: In this study, the mitogenome of the blackspotted catshark Halaelurus burgeri was first determined. This circle molecular was rich in A (30.7%)+T (30.4%), poor in C (25.0%)+G (13.8%) and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a longest control region (3481 bp with lots of repeated motifs) in sharks. Two start codons (ATG and GTG) and two stop codons (TAG and TAA/T) were found in the protein-coding genes. The 22 tRNA genes ranged from 66 bp (tRNA-Ser2) to 75 bp (tRNA-Leu1). The phylogenetic result showed that H. burgeri did not cluster to the two species of Scyliorhinidae (Cephaloscyllium umbratile and Scyliorhinus canicula).
