Calyptraeotheres, a new genus of Pinnotheridae for the limpet crab Fabia granti Glassell, 1933 (Crustacea, Brachyura)
TLDR
Its unique morphological features support the placement of F. granti as type species of a new pinnotherid crab genus, Calyptraeotheres, and this genus is ecologically different from others in the Pinnotheridae, since it is a symbiont of gastropods, family Calyaptraeidae.
INCLUSION OF THE AUSTRAL SPECIES PINNOTHERES POLITUS (SMITH, 1869) AND PINNOTHERES GARTHI FENUCCI, 1975 WITHIN THE GENUS CALYPTRAEOTHERES CAMPOS, 1990 (CRUSTACEA: BRACHYURA: PINNOTHERIDAE)
TLDR
The limpet crabs Pinnotheres politus (Smith, 1869) known from Peru to Chile, and P. garthi Fenucci, 1975, are transferred to the genus Calyptraeotheres Campos, 1990 and the diagnosis of the genus is emended in order to account for the presence or absence of the minute dactylus of the third maxilliped.
Partial revision of pinnotherid crab genera with a two-segmented palp on the third maxilliped (Decapoda : Brachyura)
TLDR
The analysis of several morphological and ecological features has led to the conclusion that P. moseri and P. chamae do not belong in the genus Pinnotheres Bosc, 1802 or any other named genera in the Pinnotheridae, and several autapomorphies separate these taxa at the generic level.
Comments on taxonomy of the genus Orthotheres Sakai, 1969 (Crustacea, Brachyura, Pinnotheridae)
TLDR
A taxonomic analysis revealed that O. rathbunae Schmitt, 1973, O. longipes (Burger, 1895), should be included in Pinnotheres Bosc, 1801-1802, and only O. strombus (Rath bun, 1905), O. serrei (Rathsbun, 1909), and O. turboe Sakai, 1969, remained unquestionably within the former genus.
Diversity and ecological remarks of ectocommensals and ectoparasites (Annelida, Crustacea, Mollusca) of echinoids (Echinoidea: Mellitidae) in the Sea of Cortez, Mexico
TLDR
The diversity of symbiotic invertebrates on intertidal and shallow water echinoids of the northwestern Gulf of California was studied and seasonal fluctuation was discovered in D. nitidus Smith (1870) and D. xanthusi Glassell (1936), which result in these species being undetectable during the winter season.
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
A new species and two new genera of pinnotherid crabs from the northeastern Pacific Ocean, with a reappraisal of the subfamily Pinnotherinae de Haan, 1833 (Crustacea: Brachyura: Pinnotheridae)
TLDR
These adult and larval shared features support the monophyly of these genera and clearly diagnose the subfamily Pinnotherinae de Haan, 1833 sensu stricto.
Calyptraeotheres hernandezi (Crustacea: Brachyura: Pinnotheridae), a new crab symbiont of the West Indian cup-and-saucer Crucibulum auricula (Gmelin) (Mollusca: Gastropoda: Calyptraeidae) off Cubagua
TLDR
The new Atlantic species differs in the female having eyes that are visible from dorsal view, the propodi of the walking legs having subparallel margins, and the ventral margin of the pollex bearing a small fringe of setae, while the Pacific limpet crab C. granti has the eyes hidden from the dorsal perspective.
Partial revision of the genus Fabia Dana, 1851 (Crustacea: Brachyura: Pinnotheridae)
TLDR
The present partial revision accepts five of the eight species assigned to Fabia Dana, 1851 (type species) and recommends a future study to determine whether the Brazilian species F. emiliai, is a junior synonym of F. byssomiae.
AUTHORSHIP AND DIAGNOSIS OF THE GENUS ARCOTHERES MANNING, 1993 (CRUSTACEA: BRACHYURA: PINNOTHERIDAE)
The pinnotherid generic name Arcotheres was first published by Burger (1895) as a synonym of Pinnotheres Bosc, 1802, and thus is unavailable. The generic name must be attributed to Manning (1993),
