“…A study by Miloslavich et al (2013) stated that gastropod abundance in an area could be described as a biodiversity hotspot or possibility of disturbances in the food chain due to gastropod dominance in competition for food. Buccinidae is also dominant in the Arctic and Antarctic, while Haminoeida has been often recorded in both temperate and tropical regions at a shallow depth of less than 15 m but rarely in deep-sea (Bouchet and Waren, 1986;Oskars et al, 2017;Too et al, 2014;Zhang and Zhang, 2018). This can be explained by the ocean currents during Southwest Monsoon that transport macrosized gastropod individuals from shallow to deeper sea (Daryabor, 2014).…”

Aim: To examine the standing stock of macrobenthos along a depth gradient at regional scales in the Sunda Shelf of Malaysian Economic Exclusive Zone (EEZ). Methodology: Macrobenthos was sampled with a Smith–McIntyre grab at 19 stations on the continental shelf of the South-western South China Sea (east coast of Peninsular Malaysia) within the EEZ and was carried out onboard MV SEAFDEC II in May/June 2016. Results: The faunal composition, abundance, and diversity of species, together with environmental parameters were studied. A total of 10,232 individuals comprising 105 families were identified. The dominant macrobenthic group was Mollusca (55.25%), followed by Annelida (26.80%) and Arthropoda (15.36%), while the Echinodermata and Miscellaneous group recorded 1.13% and 1.43% respectively. Based on Bray-Curtis species similarities, five different sample groups (SGs) were distinguished, which were located in different zones and gradients of EEZ. Interpretation: Variations in the macrobenthic community is significantly associated with depth, temperature, and salinity. Further research should be conducted on other factors that contribute to the diversity of macrobenthos along the east coast of Peninsular Malaysia’s EEZ.

Haminoeidae is the most diverse family of Cephalaspidea with 13 to 17 genera commonly recognised as valid and with 46 genera that historically have been moved back and forth between Haminoeidae and other families. Due to poor definition of most genera the family is plagued by extensive taxonomic confusion and its generic composition and internal relationships remain uncertain. In this work we have integrated the study of type material, original descriptions, shells, morpho-anatomical data, and molecular phylogenetics (Bayesian, maximum likelihood, and maximum parsimony) based on five genetic markers (the mitochondrial genes cytochrome c oxidase subunit I and 16SrRNA and the nuclear genes 18SrRNA, 28SrRNA, and histoneH3) to delimit the valid genera, define synapomorphic traits, and establish synonym lists. Three hundred and ninety novel sequences were generated. In total 14 genera were recognised; one genus (Vellicolla gen. nov.) is here described as new and an additional fifteenth group was identified, but no species could be formally ascribed to it and therefore remains unnamed (here designated informally as mini-haminoeids). The relationships of genera are discussed and seven deep clades have been identified but are not formally named because of lack of recognisable synapomorphies for several of them. A new classification for Haminoeidae is proposed including 14 valid genera and one informal group.

Abstract: My deepest gratitude is also extended to all our dedicated colleagues, who provided us with valuable samples for the project namely C. Pittman (Hawaii), J. Letourneux (French Polynesian snails), C. Carlson and the late P. J. Hoff (Guam), K. Y. Yang (Hong Kong), M.
