Pseudoleptocheliajuliae n. sp. is described from Puerto Rican waters in depths from 1 to 28 m. The new species and P. fairgo from western Australia are the only members of the genus as defined in this revision that have a distinct process on the posterior margin of the cheliped carpus. The male of P. juliae is distinguished from that of P. fairgo by this process being sub-acute and having a distinctly narrower propodus. Lang's generic diagnosis for the female of Pseudoleptochelia is incorrect… Expand
Ogleus pilarae, a new genus and species of leptocheliid tanaidacean (Crustacea: Peracarida: Tanaidomorpha) from the tropical Northwest Atlantic with observations on the genus Pseudonototanais Lang, 1973.
Ogleus pilarae n. gen., n. sp. (Leptocheliidae) is described from specimens collected at a depth of 28 m off the eastern coast of Puerto Rico. Morphologically the new genus appears to have itsExpand
First Molecularly Confirmed Conspecific Male and Female Pair in Konariinae (Crustacea: Tanaidacea), with the Description of a New Species
This species closely resembles P. kopure reported from New Zealand, but differs in having the ventral process on the chelipedal carpus longer than wide and an elongate plate-like structure that could be a reduced ischium. Expand


Taxonomische und phylogenetische Untersuchungen über die Tanaidaceen (Crustacea)
The taxonomy of the genera mentioned in the title is discussed as well as the taxonomic position of Typhlotanais longidactylus Shiino, and it is proposed that Leptochelia, Heterotanais, Hargeria, PseudoleptOChelia and PseudonototanaIS should be grouped together in the new family Leptokheliidae.

New Leptocheliidae (Crustacea: Tanaidacea: Tanaidomorpha) from Australian seagrass and macro-algal habitats, and a redescription of the poorly-known Leptochelia ignota from Sydney Harbour
A new genus (Poorea n. gen.) and five new species collected from shallow macrophyte habitats are diagnosed and a rede-scription provided for the enigmatic tanaidacean Leptochelia ignota on the basis of specimens collected near the Sydney type locality. Expand
Tanaidaceans (Crustacea: Malacostraca: Peracarida) from soft-sediment habitats off Israel, Eastern Mediterranean
Of the eight species of Apseudomorpha, one, a species of Leviapseudes, is new to the Mediterranean, and probably to science, but the damaged immature material precludes description and diagnosis, and the continued presence in this region of the Erythrean species Cristapseudes omercooperi was confirmed.

Tanaidacean Phylogeny - the Second Step: the Basal Paratanaoidean Families (Crustacea: Malacostraca)
This study should be regarded as a platform for more comprehensive analyses and systematic conclusions for the Tanaidacea and suggests a re- vised method - the 'Restricted taxa analysis' - for resolving diffi cult datasets of the 'many-taxa-few-characters' type. Expand
Akanthoparapseudes alfaroae, a new genus and species of apseudomorphan tanaidacean (Crustacea: Malacostraca: Peracarida) from Puerto Rican coastal waters
Akanthoparapseudes appears to share several synapomorphies with some species of the apseudid genus Bunakenia, suggesting the possibility that these two genera may represent transitional links between the families Apseudidae and Parapseudidae. Expand
Saltipedis (Spinosaltipedis) puertoricensis, a new subgenus and species of apseudomorphan (Crustacea: Tanaidacea: Parapseudidae) from coastal waters off Culebra Island, Puerto Rico, with keys and taxonomic observations
The new species is the fourth representative of the genus Saltipedis Guţu to be described from the western Atlantic and the new subgenus is distinguished by the presence of strongly developed accessory setae on the mandible between the base of the palp and the molar process. Expand
A new species of Mesokalliapseudes Lang, 1956 (Crustacea: Tanaidacea: Kalliapseudidae) from Puerto Rico, with remarks on the genus
A new kalliapseudid species, Mesokalliapseudes quadriflagellata n. sp. from Puerto Rico is described and illustrated. It can be distinguished from its congeners by the following combination ofExpand
The new and the old: littoral tanaidomorph Tanaidacea (Crustacea: Peracarida) from the Andaman Islands, Indian Ocean
A redescription of the leptocheliid Konarus crassicornis is given, discussing its close similarity to the generotype, K. cheirus, and two new species of tanaidaceans are described, one of the tanaid genus Zeuxo, showing similarities to Z. (Parazeuxo) kurilensis and representing the first anatanaid to be recorded from the region. Expand
Shallow water tanaidaceans (Crustacea: Peracarida: Tanaidacea) from New Caledonia and the Loyalty Islands
The Pacific collections by the MUSORSTOM campaigns of the Paris Museum over the last twenty years include a total of four species of Tanaidacea from shallow waters of the New Caledonia region and all new to science, including a species with unusual cheliped carpus morphology which is placed in a new genus as Konarus cheiris.
