A New Caridean Shrimp of the Family Bresiliidae From Thermal Vents of the Galapagos Rift

First record and a new species of Alvinocaris Williams & Chace, 1982 (Crustacea: Decapoda: Caridea: Alvinocarididae) from the Indian Ocean

“…These two species are also similar in the length and armature of the rostrum, little elevated dorsum of the carapace and the general armature of the third to fifth pereopods. Nevertheless, the new species can be distinguished from A. lusca by some minor morphological differences (Williams & Chace 1982;Komai & Segonzac 2005): in A. solitaire sp. nov., the pterygostomial tooth is weak, not exceeding the antennal tooth, whereas it is stronger and exceeds the latter in A. lusca; the pleuron of the third pleomere is armed with small but conspicuous teeth on the posteroventral margin in the new species, rather than unarmed in A. lusca; the posterior margin of the telson is devoid of setae medially in the new species, whereas there are a few short plumose setae on the medial part of the posterior margin in A. lusca.…”

“…The caridean family Alvinocarididae Christoffersen, 1986 is currently comprised of 27 described species in eight genera: Alvinocaris Williams & Chace, 1982, Rimicaris Williams & Rona, 1986, Chorocaris Martin & Hessler, 1990, Opaepele Williams & Dobbs, 1995, Mirocaris Vereshchaka, 1997, Nautilocaris Komai & Segonzac, 2004, Shinkaicaris Komai & Segonzac, 2005, and Alvinocaridinides Komai & Chan 2010. These species inhabit chemosynthetic environments (deep-sea hydrothermal vents and/or cold seeps) at depths of 252-4960 m (Nye et al 2012;Lunina & Vereshchaka 2014).…”

Phylogenetic relationships between Oplophoridae, Atyidae, Pasiphaeidae, Alvinocarididae Fam. N., Bresiliidae, Psalidopodidae and Disciadidae (Crustacea caridea atyoidea)

“…The P a s i p h a e i d a e , Psalidopodidae and Bresiliidae sensu Williams & Chace (1982) and Kensley (1983) are all descendants of the same ancestral species which also gave rise to the Oplophoridae and Atyidae. All these groups thus belong to the larger monophyletic taxon Atyoidea, and the concepts O p l o p h o r o i d e a , P a s i p h a e o i d e a , Bresilioidea and Psalidopodoidea must all be included under the synonymy of the amended taxon A t y o i d e a .…”

A new family for a deep-sea caridean shrimp from North Atlantic hydrothermal vents

“…Recent collections have resulted in the discovery and description of several distinctive new shrimp taxa, such as Alvinocaris (Williams & Chace, 1982) and members of three other new genera, Rimicaris, Chorocaris, and Opaepele (Williams & Rona, 1986;Williams, 1988;Martin & Hessler, 1990;Martin & Christiansen, 1995;Williams & Dobbs, 1995).…”
