Apseudomorph tanaidaceans from recent samples of the South China Sea benthos off Brunei have been examined. The habitats were sandy substrata from between 5 and 90 m depth. Fourteen species of the four families considered here were discovered. A new species of Tanapseudes is described. The distribution of Phoxokalliapseudes gobinae is analyzed. Biropalostoma goofi is recorded for the first time in Brunei waters. One new species of the Apseudidae (in the genus Bunakenia) and four new species of the Parapseudidae (one each in the genera Platylicoa and Pakistanapeudes, and two in a new genus Actenos, of the subfamily Pakistanapseudinae) are described. The genus Platylicoa is moved to the Pakistanapseudinae, and the genus Hainanius is returned to the Parapseudidae (Parapseudinae). Apseudes tenuicorporeus is moved from Biropalostoma to the new pakistanapseudin genus described herein. Copyright © 2013 Magnolia Press.

Over the last 160 years, a possibly excessive number of species of the tanaidomorphan genus Leptochelia has been described based on its dimorphic males, followed by excessive synonymization to the point of suggesting one cosmopolitan speciescalled either L. dubia or L. savignyifor taxa in which the male cheliped is shorter than the body length. It has become apparent over the last 25 years that, in a genus with little dispersive capability, there are numerous, and often sympatric, species of Leptochelia worldwide, none of them cosmopolitan, and distinguished principally on adult female morphology, although that morphology is very conservative. To resolve the resulting confusion over attribution of northeast Atlantic populations to one or other of the earlier-described species, specimens from Madeira, the type locality of L. savignyi, have been analyzed in comparison with material from the western English Channel and northwest Spain. The species is confirmed as Leptochelia savignyi sensu stricto, which is fully redescribed, compared with currently understood sympatric species, and intraspecific and ontogenetic variation is discussed. © 2010 Biological Society of Washington.

The tanaidid genus Sinelobus was long considered to be monotypic, comprising a cosmopolitan species, S. stanfordi, predominantly associated with restricted, largely hypohaline waters. Recent discoveries of distinct species of Sinelobus in Australia have prompted closer examination of material from localities remote from the Central American Pacific coast (the type-locality of S. stanfordi). Re-examination of material from the Netherlands (north-east Atlantic) and from Hong Kong (South China Sea) has resulted in the distinction of two new species, which are described herein. Problems with the familial nomenclature of this taxon have been identified, and the family name is corrected to Tanaididae.http://zoobank.org/urn:lsid:zoobank.org:pub:811604EA-B3B2-4ED5-8F86-3527BDF635D7. © 2014 © 2014 Taylor & Francis.

Following recent revelations regarding males with subchelate chelipeds in the tanaidacean genus Parakonarus, a number of Australian leptocheliid taxa are re-assessed, and their males and females variously re-allocated. To assist the interpretation of taxa with subchelate males, Heterotanais anomalus Sars is redescribed based on material from the Balearic Islands. The males of Konarus are now known to have a subchelate cheliped. The male (only) of Pseudoleptochelia bulbus from Melanesia is re-assigned to Konarus cheiris, while Pseudoleptochelia bulbus sensu stricto is reassigned to Leptochelia together with its "minuta"-type male, as Leptochelia bulbus. Pseudoleptochelia straddi is re-assigned to Konarus, together with its females from Queensland, Australia, which were previously assigned to Konarus cheiris. Pseudoleptochelia fairgo is confirmed as a member of Parakonarus, but material from Queensland is re-described as a new species. Other species previously assigned to Pseudoleptochelia are re-assessed: P. inermis, P. mercantilis and P. mortenseni sensu stricto are transferred to Leptochelia. The "small females" and males of P. mortenseni are transferred to Parakonarus as a new species. P. antarctica is provisionally reverted to Heterotanais, P. mergellinae to Leptochelia, and P. filum is tentatively transferred to Pseudonototanais. Pseudoleptochelia magna is synonymized with P. anomala. Pseudoleptochelia provincialis is tentatively transferred to Parakonarus. Pseudoleptochelia occiporta (females only) is reassigned to Leptochelia; the male of P. occiporta is considered to represent a species of Parakonarus. Pseudoleptochelia juliae is reassigned to Parakonarus. Konarus, Makraleptochelia, Bassoleptochelia, Parakonarus and Pseudoleptochelia are placed in the new subfamily Konariinae. Generic relationships in this subfamily were confirmed by Principle Components Analysis. Catenarius is placed in the new subfamily Catenariinae. Copyright © 2013 Magnolia Press.

Deep-sea pycnogonid material collected during the N/O Alis Campagnes SalomonBOA 3 to the Solomon Islands in 2007, Terasses to New Caledonia in 2008, Tarasoc to the Tuamoto Archipelago and Tarava Seamounts in 2009, Biopapua to Papua New Guinea in 2010, and Exbodi to New Caledonia in 2011, has been analyzed. This includes the first collection of deep-sea pycnogonids from the waters of Papua New Guinea. The material includes 71 specimens from 14 species in seven genera. Most are frequently-recorded species of the genus Colossendeis, but there are also four species new to science, Ascorhynchus quartogibbus n. sp., Cilunculus roni n. sp., Phoxichilidium alis n. sp., Pycnogonum papua n. sp. A specimen from New Caledonia, identified by Stock in 1997 as Pycnogonum occa Loman, 1908, but not figured or described, has been re-examined, and found also to be a distinct species, Pycnogonum staplesi n. sp. © Publications Scientifiques du Muséum national d'Histoire naturelle, Paris.
