A redescription of Diogenes senex Heller, 1865, sensu stricto (Decapoda: Anomura: Paguridea: Diogenidae)

Diogenes senex Heller, 1865 sensu stricto is redescribed from specimens collected in Australia, particularly in and around the type locality of Sydney. A neotype has been designated. Comparisons of this material with other specimens identified as D. senex by a number of authors has shown that at present only the Australian material truly represents Heller's taxon

Reinstatement and Rediagnosis of Catapaguroides setosus and Description of a Second Hawaiian Species of the Genus (Decapoda: Anomura: Paguridea: Paguridae)

A species of the hermit crab genus Catapaguroides recently discovered in a sand-dwelling Halimeda community on the island of Maui, Hawaiian Islands, prompted a reexamination of the holotype of Catapaguroides setosus (Edmondson, 1951), described from off the south coast of O'ahu. The latter species, currently considered a junior subjective synonym of Catapaguroides fragilis (Melin), is herein adjudged neither synonymous with C. fragilis nor conspecific with the second Hawaiian species. Catapaguroides setosus is reinstated with full specific rank, rediagnosed, and illustrated. The second species, Catapaguroides hooveri McLaughlin & Pittman, n. sp., is described and illustrated

The Magnitude of Global Marine Species Diversity

Background: The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be discovered. Results: There are ∼226,000 eukaryotic marine species described. More species were described in the past decade (∼20,000) than in any previous one. The number of authors describing new species has been increasing at a faster rate than the number of new species described in the past six decades. We report that there are ∼170,000 synonyms, that 58,000–72,000 species are collected but not yet described, and that 482,000–741,000 more species have yet to be sampled. Molecular methods may add tens of thousands of cryptic species. Thus, there may be 0.7–1.0 million marine species. Past rates of description of new species indicate there may be 0.5 ± 0.2 million marine species. On average 37% (median 31%) of species in over 100 recent field studies around the world might be new to science. Conclusions: Currently, between one-third and two-thirds of marine species may be undescribed, and previous estimates of there being well over one million marine species appear highly unlikely. More species than ever before are being described annually by an increasing number of authors. If the current trend continues, most species will be discovered this century

Pagurus imafukui, a New Species of Deep-water Hermit Crab (Crustacea : Anomura : Paguridae), with Notes on its Larvas

A new species of the hermit crab genus Pagurus was collected from depths of 126 and 300 meters off the Pacific coast of Japan. This is a strongly polymorphic species, which has been found only in shells of scaphopods (Order Dentalioida). Pagurus imafukui new species is described, illustrated and its morphological variations discussed. Aspects of early larval morphology of this species are also given
