Raymond B. Manning and Darryl L. Felder. The Pinnixa cristata Complex in the Western Atlantic, with Descriptions of Two New Species. Smithsonian Contributions to Zoology, number 473, 26 pages, frontispiece, 14 figures, 1989.—The Pinnixa cristata Complex, all members of which appear to be commensals of ghost shrimps, Family Callianassidae, or burrowing worms, comprises six species in the western Atlantic: P. aidae Righi, from Brazil; P. behreae, new species, from the northern and northwestern… 

The Pinnotheridae of the northeastern Pacific (Alaska to Mexico): zoogeographical remarks and new bivalve hosts (Crustacea, Brachyura, Pinnotheridae).

An updated checklist with remarks on zoogeography for the 60 pinnotherid species, included in 23 genera, of the northeastern Pacific region (Alaska to the Mexican tropical Pacific) is given.

Systematics of the genus Scleroplax Rathbun, 1893 (Crustacea: Brachyura: Pinnotheridae)

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

Molecular phylogeography of Tumidotheres maculatus (Say, 1818) and Zaops ostreus (Say, 1817) (Crustacea: Decapoda: Pinnotheridae) in the western Atlantic, with description of a new species and synonymy of Epulotheres Manning, 1993

It is found that most populations of Tumidotheres belonged to a single species, but that specimens from the western Caribbean Sea represented an undescribed congener, herewith described and named.

New record of calyptraeid hosts for the pea crab Calyptraeotheres garthi (Fenucci, 1975) (Decapoda, Pinnotheridae) in Argentina

There are notable differences in prevalence of C. garthi on each host, which suggest that the symbiont might prefer species of Crepidula over the others genera (Trochita and Bostrycapulus), and there exists an apparent relationship between host size and prevalence.

Distribuição geográfica dos Brachyura (Crustacea, Decapoda) coletados na plataforma continental do norte e nordeste do Brasil

The Brachyura collected on the continental shelf of Northern and Northeastern Brazil understood between the latitudes 4o27'N and 3o43'S and the longitudes of 50o00'W-38o000'W, were represented by 133 species, 79 genera and 15 families, except the majority of the species (125) was found exclusively in the western Atlantic.

NEW DECAPODS FROM THE NAVIDAD FORMATION (MIOCENE) OF CHILE

This report greatly increases the known number of fossil decapods from Chile and sets the stage for paleobiogeographic comparison of the decapod faunas of Chile and Argentina.

Population dynamics of the pea crab Austinixa aidae (Brachyura, Pinnotheridae): a symbiotic of the ghost shrimp Callichirus major (Thalassinidea, Callianassidae) from the southwestern Atlantic

The data indicated that the population demography of A. aidae was characterized by a bimodal size-frequency distribution that remained similar throughout the study period, which confirms the pattern observed in other symbiontic pinnotherids.

Molecular evidence for non-monophyly of the pinnotheroid crabs (Crustacea : Brachyura : Pinnotheroidea), warranting taxonomic reappraisal

The relationships within and among some taxa are resolved to greater or lesser extent and the phylogenetic biodiversity of pinnotherid crabs is revealed.

Population dynamics of Pinnixa patagoniensis RATHBUN, 1918 (Brachyura : Pinnotheridae) a symbiotic crab of Sergio mirim (Thalassinidea : Callianassidae) in Cassino Beach, Southern Brazil

The population dynamics of this crab were studied from monthly samples taken between March 1989 and November 1991 near the Patos Lagoon outlet, southern Brazil, and found the annual recruitment pattern was bimodal, with a minor peak in summer and a fall peak that accounted for almost 70% of the population maintenance.

Molecular evidence for non-monophyly of the pinnotheroid crabs (Crustacea : Brachyura : Pinnotheroidea), warranting taxonomic reappraisal

Molecular genetic markers were used to infer a phylogeny for the family Pinnotheridae De Haan, 1833 to reevaluate the phylogeny and systematics at the level of its subfamilies and genera and resolved the relationships within and among some taxa.
