Abstract The calanoid copepod Lucicutia hulsemannae Markhaseva & Ferrari, 2005 has, until now, only been recorded from the eastern tropical Pacific Ocean, i.e., in its description as a new species. The present study now reports L. hulsemannae for the first time from the southern basin of the South China Sea (7°59.57′N 113°0.1′E), at depths of 500-800 m. The main morphological characteristics of females of this species are: (i) Cephalosome with a pair of strong, triangular, lateral protrusions; (ii) plug of genital double-somite conical in lateral view, with swollen base; (iii) second urosomal somite significantly wider and shorter than third; (iv) inner marginal seta of second exopodal segment of fifth pereiopod (P5) thin towards its tip. This finding considerably expands the reported global distribution of L. hulsemannae, at the same time updating the checklist of copepods for Chinese waters.

Abstract The genus Xanthocalanus inhabits the intermediate and deep waters of the world ocean. The present study records and describes the first female individual of Xanthocalanus agilis Giesbrecht, 1893, collected in the South China Sea (13°0.21′N 113°0.21′E) at depths of 500-800 m. This species was identified by the following morphological characteristics: (i) rostrum with 2 slender filaments; (ii) posterolateral corners of fifth thoracic somite protuberant and triangular, reaching the posterior margin of genital somite; (iii) first segment of fifth pereiopod (P5) with a list of inner marginal spinules, distal segment short with 3 robust terminal spines. This finding expands the known global and vertical distribution of X. agilis.

Monotaxis heterodon (Bleeker, 1854) is widespread in the Indo-Pacific Ocean, however, it was reported that Monotaxis grandoculis (Forsskål, 1775) was the single species of Monotaxis in this area. We collected four M. heterodon specimens from the lagoon waters of Mischief Reef in South China Sea. A morphometric study was taken to confirm the occurrence of M. heterodon in the seawaters of the South China Sea and thoroughly separate them from M. grandoculis. In addition, DNA barcoding was taken for the classification of specimens. The mean genetic distance within M. heterodon group was 0.24 percentage points, group mean distance between M. heterodon and M. grandoculis was 8.71 percentage points. The phylogenetic analysis confirmed the existence of M. heterodon in the lagoon waters of the South China Sea. This study will contribute to species identification within this genus distributed in the South China Sea.

The Indian sillago, Sillago indica McKay, Dutt & Sujatha, 1985, is redescribed on the basis of three paratypes and two newly collected specimens.  The presence of two posterior extensions of the swimbladder instead of one suggests that it belongs to the subgenus Sillago.  Comments on its subgeneric status and comparisons with members of Sillago (Sillago) are provided.  Two specimens collected from Vietnam represent the first record of the species from the South China Sea, western Pacific Ocean.

Large Distribution

In this study we investigated 745 specimens of purpleback flying squid Sthenoteuthis oualaniensis across a large distribution range to investigate geographic, intraspecific and sexual variations in beak morphology. Beak morphometric variables showed significant spatial and intraspecific differences (P<0.05), with samples from the north-western Indian Pacific Ocean and the South China Sea having the largest and smallest beaks respectively. Multivariate statistical analysis indicated that the morphological characteristics of squid beaks would be useful for the identification of population structures and sex determination. Environmental conditions may be the major reason for variations in beak morphology between geographic populations throughout large distribution areas. In contrast, genetic differences may contribute to most of the intraspecific variation in beak morphology in the South China Sea. To address this clearly, further research needs to be done on morphology combined with genetic evaluation to compare methods of geographic and intraspecific population identification.
