Abstract: Here we provide a Code-compliant description of Ostrea oleomargarita Oliver, Salvi, and Al-Kandari, sp. nov as reported in Salvi et al. (2022) and complemented with the ZooBank registration numbers of the publication and of the new species name. Results of phylogenetic, species delimitation, and morphological analyses on which the systematic assessment of this new species is based can be found in Salvi et al. (2022).

Pinctada phuketensis sp. nov. (Bivalvia, Ostreida, Margaritidae), a new pearl oyster species from Phuket, western coast of Thailand https://zookeys.pensoft.net/article/87724/ ZooKeys 1119: 181-195

Abstract: A new species of the genus Pinctada is described from samples collected from the east coast of Phuket Island, Thailand in the Andaman Sea. Pinctada phuketensis sp. nov. is distinguished from other species on both molecular and morphological data. Morphologically, the valves of P. phuketensis are characterized by a slightly developed to undeveloped posterior auricle, a small, narrow slit-like byssal notch, the absence of hinge teeth, and a pale to transparent non-nacreous border, with a few dark brown or red blotches. This new species resembles P. fucata but differs by its smaller size and the absence of hinge teeth. Phylogenetic analyses based on both mitochondrial (COI) and nuclear (18S rDNA, ITS1 and ITS2) genes and species delimitation using COI data strongly support that P. phuketensis is a distinct species, which is closely related to Pinctada albina and Pinctada nigra.

Molecular and morphological systematics of a new, reef forming, cupped oyster from the northern Arabian Gulf: Talonostrea salpinx new species https://zookeys.pensoft.net/article/66992/ ZooKeys 1043: 1-20

DOI: 10.3897/zookeys.1043.66992

Authors: Manal Al-Kandari, P. Graham Oliver, Daniele Salvi

Abstract: The rocky northern shores of Kuwait and those of the western, inner shores of Kuwait Bay are dominated by a small, densely encrusting oyster. The identity of this oyster has never been confirmed and was mistaken previously for a small Saccostrea. The shell morphology suggests that this species belongs to the subfamily Crassostreinae, but within that subfamily, the presence of marginal erect trumpet-shaped projections is so far unique. Phylogenetic analyses based on mitochondrial DNA sequence data confirmed that this species belongs to the Crassostreinae and has a sister position to the clade including Talonostrea talonata and T. zhanjiangensis. Genetic distance between this species and Talonostrea species is remarkably high, being ~20% for the cytochrome oxidase I gene and ~7% for the 16S rRNA gene. Based on morphological and molecular analyses, this oyster is therefore described here as Talonostrea salpinx Oliver, Salvi & Al-Kandari, sp. nov. Shell morphology is shown to be variable, and the different forms encountered are described. The wider distribution and origins of this species, whether native or introduced, are discussed.

Reproductive traits of the symbiotic pea crab Austinotheres angelicus (Crustacea, Pinnotheridae) living in Saccostrea palmula (Bivalvia, Ostreidae), Pacific coast of Costa Rica https://zookeys.pensoft.net/article/4262/ ZooKeys 457: 239-252

DOI: 10.3897/zookeys.457.7851

Authors: Carolina Salas-Moya, Sebastián Mena, Ingo Wehrtmann

Abstract: Pea crabs of the family Pinnotheridae exhibit a symbiotic life style and live associated with a variety of different marine organisms, especially bivalves. Despite the fact that pea crabs can cause serious problems in bivalve aquaculture, the available information about the ecology of these crabs from Central America is extremely limited. Therefore, the present study aimed to describe different reproductive features of the pinnotherid crab Austinotheres angelicus associated with the oyster Saccostrea palmula in the Golfo de Nicoya, Pacific coast of Costa Rica. Monthly sampling was conducted from April to December 2012. Average carapace width (CW) of the 47 analyzed ovigerous females was 7.62 mm. The species produced on average 2677 ± 1754 recently -extruded embryos with an average volume of 0.020 ± 0.003 mm3; embryo volume increased during embryogenesis by 21%, but did not vary significantly between developmental stages. Brood mass volume varied greatly (between 11.7 and 236.7 mm3), and increased significantly with female CW. Females invested on average 76.7% (minimum: 21.7%; maximum: 162.8%) of their body weight in brood production, which confirms a substantially higher energy allocation for embryo production in pinnotherid crabs compared to free-living decapods.
