Several rare or uncommon, mostly infaunal decapod crustaceans are reported from intertidal and shallow subtidal habitats of Lombok, Indonesia. The alpheid shrimps Alpheus angustilineatus Nomura & Anker, 2005, Athanas shawnsmithi Anker, 2011, Jengalpheops rufus Anker & Dworschak, 2007, Salmoneus alpheophilus Anker & Marin, 2006, Salmoneus colinorum De Grave, 2004, and the laomediid mud-shrimp Na...

Alpheus brevicristatus De Haan, 1849, one of the largest alpheid shrimps, is known to occur in Korea Strait and Yellow Sea of Korea, Japan, and Taiwan (Kim, 1977; Banner and Banner, 1984; Jeng and Chang, 1985). It inhabits shallow burrows in soft mud flats of estuary and Zostera belts of bay bottom (Miya, 1971) and lives in a symbiotic association with the gobies (Banner and Banner, 1982). Very...

The Alpheidae-possibly the most diverse family of recent decapod crustaceans-offers attractive opportunities to study the evolution of many intriguing phenomena, including key morphological innovations like spectacular snapping claws, highly specialized body forms, facultative and obligate symbioses with many animal groups, and sophisticated behaviors like eusociality. However, studies of these...

Some small collections of alpheid shrimp resulting from the participation of the United States research vessels in the International Indian Ocean Expeditions are reported: 53 species in six genera were collected, with many of the collection records extending the known range of the various species within the Indian Ocean. Two new species are described from the deeper sublittoral zone: Synalpheus...

A new species of the alpheid shrimp genus Triacanthoneus Anker, 2010, is described based on material collected in a marine cave off Caye Chapel, Belize. Triacanthoneus chapelianus sp. nov. is the fifth species in the genus and can be distinguished from the other four species by the position of the dorsolateral teeth on the carapace, which in the new species have an anterior (= submarginal) posi...

A new genus, Harperalpheus, gen. nov., is established for H. pequegnatae, sp. nov., on the basis of specimens collected from sandy subtidal sediments off Galveston, Texas, and Sapelo Island, Georgia, USA. The holotype female, the largest and most intact specimen of the type series, is ovigerous and bears an appendix masculina on the second pleopod. The new genus is characterised by conspicuous,...

Arthur Anker, Galena-Vantsetti Murina, Carlos Lira, Jonathan A. Vera Caripe, A. Richard Palmer, and Ming-Shiou Jeng (2005) Macrofauna Associated with Echiuran burrows: a review with new observations of the innkeeper worm, Ochetostoma erythrogrammon Leuckart and Rüppel, in Venezuela. Zoological Studies 44(2): 157-190. Because of their size and semipermanent nature, burrows of larger echiuran wor...

A miniature alpheid shrimp, Leslibetaeus caribbaeus n. sp., is described on the basis of a single female specimen collected in Sandy Bay, Tobago, in 1992. The new species is closely related to L. coibita Anker, Poddoubtchenko & Wehrtmann, 2006 from the Pacific coast of Panama, the type species and the only other known species of Leslibetaeus Anker, Poddoubtchenko & Wehrtmann, 2006, differing fr...

A new species of the alpheid shrimp genus Athanas Leach, 1814 is described based on a single specimen, an ovigerous female from Nha Trang Bay, Vietnam. Athanas manticolus sp. nov. differs from all other species of Athanas by the presence of a small post-rostral tubercle, combined with a minutely toothed rostrum, reduced extra-corneal teeth, and the absence of infra-corneal and supra-corneal tee...
