Zootaxa: Systematics of the Genus Scleroplax Rathbun, 1893
Zootaxa 1344: 33–41 (2006) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA 1344 Copyright © 2006 Magnolia Press ISSN 1175-5334 (online edition) Systematics of the genus Scleroplax Rathbun, 1893 (Crustacea: Brachyura: Pinnotheridae) ERNESTO CAMPOS Facultad de Ciencias, Universidad Autónoma de Baja California, Apartado Postal 2300, Ensenada, Baja California, 22800 México. E-mail: [email protected]; [email protected] Abstract The taxonomic status of the monotypic genus Scleroplax Rathbun, 1893, is evaluated and separated from other genera of the Pinnixa White, 1846, complex. Distinguishing characters of Scleroplax are a hard, subheptagonal and dorsally, highly convex carapace, and a third maxilliped with a propodus that extends to the end of the dactylus. The genera Scleroplax, Pinnixa, Austinixa Heard & Manning, 1997, Glassella Campos & Wicksten, 1997, Indopinnixa Manning & Morton, 1987, and Tetrias Rathbun, 1898, share a carapace than is wider than long and a distinct lateral exopod lobe on the third maxilliped, all of which may represent monophyletic characters. Updated information on the distribution and hosts of S. granulata Rathbun, 1893, indicate that the species now ranges from Vancouver Island, British Columbia, Canada to El Coyote estuary, Punta Abreojos, Baja California Sur, México. It inhabits burrows of the echiuroid Urechis caupo Fisher & MacGinitie, 1928, and the mud shrimps Neotrypaea californiensis (Dana, 1854), N. gigas (Dana, 1852) (new host record), Upogebia pugettensis (Dana, 1852), and occasionally U. macginiteorum Williams, 1986 (new host record).

Systematics, Phylogeny, and Taphonomy of Ghost Shrimps (Decapoda): a Perspective from the Fossil Record

Abstract Ghost shrimps of Callianassidae and Ctenochelidae are soft-bodied, usually heterochelous decapods representing major bioturbators of muddy and sandy (sub)marine substrates. Ghost shrimps have a robust fossil record spanning from the Early Cretaceous (~ 133 Ma) to the Holocene and their remains are present in most assemblages of Cenozoic decapod crustaceans. Their taxonomic interpretation is in flux, mainly because the generic assignment is hindered by their insufficient preservation and disagreement in the biological classification. Fur- thermore, numerous taxa are incorrectly classified within the catch-all taxonCallianassa . To show the historical patterns in describing fos- sil ghost shrimps and to evaluate taphonomic aspects influencing the attribution of ghost shrimp remains to higher level taxa, a database of all fossil species treated at some time as belonging to the group has been compiled: 250 / 274 species are considered valid ghost shrimp taxa herein. -

Shrimp Neotrypaea Californiensis to Intertidal Shell and Mud Habitats
MARINE ECOLOGY PROGRESS SERIES Published April 30 Mar Ecol Prog Ser l Effects of substrate selection and post-settlement survival on recruitment success of the thalassinidean shrimp Neotrypaea californiensis to intertidal shell and mud habitats Kristine L. Feldmanlr*,David A. ~rmstrongl,David B. ~ggleston'~",Brett R. ~umbauld~ 'School of Fisheries, Box 357980, University of Washington, Seattle, Washington 98195, USA 'Washington State Department of Fish and Wildlife, Willapa Bay Field Station, PO Box 190, Ocean Park, Washington 98640, USA ABSTRACT: We quantified recruitment of young-of-the-year (YOY)burrowing thalassinidean shrimp Neotrypaea californiensis to 2 habitats of differing structural complexity-epibenthic bivalve shell and bare mudflat-and examined how differential settlement and post-settlement predation influence patterns of YOY abundance. Local densities of shrimp were quantified prlor to construction of shell habitat in Grays Harbor estuary, Washington (USA). Subsequent recruitment of YOY shrimp to epiben- thic shell and bare mudflat was measured during a peak settlement pulse and 10 mo post-settlement. In addition, patches of sediment overlying shell within the shell plot ('subsurface shell') were sampled 10 mo post-settlement. Differential settlement in shell and mud habitats was quantified in field and laboratory experiments. We also examined predator-prey interactions between YOY Dungeness crabs Cancer magister and newly settled shrimp in shell habitat in a laboratory experiment in which prey consumption crab-' was quantified as a function of shrimp density. Results of our studies indicate that dense coverage of epibenthic shell applied to the intertidal site reduced recruitment of ghost shrimp. Epibenthic shell habitat had significantly fewer YOY shrimp than bare mudflat at peak settlement and 10 mo post-settlement, and significantly fewer shrimp than 'subsurface shell' at 10 mo post-settlement. -

Abstract: From small phosphatic nodules in sandy deposits of Neogene age, previously excavated at Emblem (northwest Belgium) and currently suction dredged at Langenboom (southeast Netherlands), several chelipeds as well as fragments of carapace and abdomen of an axiid shrimp have been col- lected. These remains are here described as a new genus and species, which constitute the first record of the family Axiidae from Neogene strata in the North Sea Basin and the second species to be re- ported from Pliocene strata worldwide.

Dworschak* Abstract Axiidea and Gebiidae (formerly treated together as Thalassinidea) have a crypic lifestyle. Collecting these shrimp therefore requires special field methods. The present paper reviews these methods according to habitats and provides recommendations as well as data on their efficiency. In addition, information on the preservation of these animals is presented. Key words: Thalassinidea, Axiidea, Gebiidea, method, collecting, preservation Zusammenfassung Maulwurfskrebse aus den zwei Unterordungen der zehnfüßigen Krebes Axiidea und Gebiidea (früher zusammengefaßt als Thalassinidea) kommen in temperaten, subtropischen und tropischen Meeren vor und zeichnen sich durch ein Leben im Verborgenen aus. Viele Arten legen tiefe und ausgedehnte Bauten an. Diese Lebensweise erfordert eigene Methoden, um die Krebse zu fangen. Die verschiedenen Fangmethoden werden hier vorgestellt und Angaben zur Effizienz gemacht. Zusätzlich werden Angaben zur Fixierung und Konservierung der Krebse präsentiert. Introduction Formerly treated together as the thalassinideans, the infraorders Gebiidea DE SAINT LAURENT, 1979 and Axiidea DE SAINT LAURENT, 1979 represent two distinctly separate groups of decapods (ROBLES et al. 2009; BRACKEN et al. 2009; DWORSCHAK et al. 2012, POORE et al., 2014). They are commonly called mud shrimp or ghost shrimp, although they are only distantly related to true (dendrobranchiate or caridean) shrimp.
