“…Calyptraeotheres politus (Smith, 1870) is found along the south‐eastern Pacific coast, living in limpets of the genera Crepipatella and Calyptraea (Campos, ). Calyptraeotheres hernandezi Hernández‐Ávila & Campos, and Calyptraeotheres granti (Glassell, 1933) establish symbiosis with limpets of the genus Crucibulum , and are present on Cubagua Island, Venezuela, and in the Mexican Pacific, respectively. Finally, Calyptraeotheres pepeluisi Campos & Hernández‐Ávila, was described from a single female specimen found in Michoacán, on the Pacific coast of Mexico (Campos & Hernández‐Ávila, ).…”

“…Later, based on the morphology of adult crabs, all pinnotherids living as symbionts of limpets of the Calyptraeidae family were reassigned to the genus Calyptraeotheres (Campos, ). This genus was subdivided into two subgroups, one austral ( C. garthi and C. politus ) and one subtropical−tropical ( C. hernandezi and C. granti ), based on characters of the third maxilliped; the austral subgroup can be recognized by a three‐segmented third maxilliped, whereas this character is two‐segmented in the subtropical−tropical subgroup (Hernández‐Ávila & Campos, ). Last, two studies, one based on larval morphology (Ocampo et al ., ) and another based on larval and adult morphological characters (Campos & Hernández‐Ávila, ), supported the hypothesis that Calyptraeotheres is a monophyletic clade.…”

We used mitochondrial cytochrome oxidase I (COI) and the large ribosomal subunit (16S) genes to establish evolutionary relationships amongst species of Calyptraeotheres, evaluate their usefulness as DNA‐barcoding genes, and assess molecular diversity at the population level within Calyptraeotheres garthi. Bayesian, maximum likelihood, and maximum parsimony phylogenies confirmed the monophyly of Calyptraeotheres, showing that the ancestor of C. garthi, Calyptraeotheres hernandezi, and Calyptraeotheres granti radiated after the formation of the Panamanian isthmus. This finding contradicts the austral/tropical hypothesis previously proposed based on morphological data. The COI and 16S distance matrices supported separation of species as well as the genera, and corroborated that DNA barcoding is a useful tool and complements the classical taxonomy in Pinnotheridae. Phylogenetic and genetic distance analyses suggested that C. hernandezi is a junior synonym of C. garthi. Finally, C. garthi did not show a population structure across its distribution range, and showed a pattern consistent with a recent population expansion event that began 230–300 Kya. © 2013 The Linnean Society of London

“…Additionally, P. caribaeus, P. herbstii, P. lherminieri, P. galathinus and C. americanus have been reported from various locations in Venezuela and are associated with coral, rubble and Thalassia beds (Rodríguez 1980, Carmona-Suárez and Conde 1996, Hernández-Ávila et al 2007. Some infrequent species have recently been reported in the region (Hernández-Ávila 2004, Hernández-Ávila and Campos 2006, Hernández-Ávila et al 2007. Thus, these bivalve aggregations represent a potential habitat for some common shallow-water decapod crustaceans and for some uncommon species.…”

SUMMARY: Beds of the Atlantic pearl oyster (Pinctada imbricata) and the turkey wing (Arca zebra) of contrasting population densities were evaluated to determine the occurrence of associated decapod crustaceans. In these beds at Cubagua Island, Venezuela, we recorded 40 decapod species belonging to 18 families. Mithraculus forceps (Majidae), Pilumnus caribaeus (Pilumnidae), Cuapetes americanus (Palaemonidae) and Petrolisthes galathinus (Porcellanidae) were the most common species found in these assemblages. The medium-and high-density bivalve beds exhibited more species and a greater abundance of associated decapods than the low-density bivalve beds, and more taxonomic distinctness. Multivariate analysis detected different groups of decapods in the low-density beds and the medium-to high-density beds. Additionally, similarities were found in the communities of crustaceans in the beds of Atlantic pearl oysters and turkey wing, demonstrating that bed density is important for the composition of associated fauna.Keywords: Decapoda, benthos, bivalve beds, complexity, Caribbean, richness. RESUMEN: Composición de ensambles de crustáceos decápodos en bancos de Pinctada imbricata y arca zebra (Mollusca: Bivalvia) en la Isla de Cubagua, Venezuela: Efecto de la densidad del banco. -Bancos de la ostra perla del Atlántico (P. imbricata) y de la pepitona (A. zebra) de densidades poblacionales contrastantes fueron evaluados para determinar la ocurrencia de crustáceos decápodos asociados. En estos bancos en la isla de Cubagua, Venezuela, fueron colectadas 40 especies de decápodos, pertenecientes a 18 familias. Mithraculus forceps (Majidae), Pilumnus caribaeus (Pilumnidae), Cuapetes americanus (Palaemonidae) y Petrolisthes galathinus (Porcellanidae) fueron las especies más comunes en estos ensambles. Los bancos de densidad media y alta mostraron mayor riqueza de especies y abundancia que los de baja densidad de bivalvos, así como mayor distinción taxonómica. Análisis multivariados detectaron diferentes grupos de decápodos en los bancos de baja densidad en relación a los de densidad media y alta. Adicionalmente, la fauna encontrada en bancos de ostra perla y pepitona no mostró diferencias, demostrando que la densidad es importante para la composición de la fauna asociada.

“…With the exception of Tunicotheres moseri (Bolaños et al 2004), the larvae of pinnotherids are free-living and the number of zoeal stages ranges from 2 to 5. The genus Calyptraeotheres Campos, 1990 consists of four species: Calyptraeotheres garthi Fenucci, 1975 from southwestern Atlantic, C. hernandezi Hernández-Á vila and Campos, 2006 from Cubagua Island, Venezuela, C. granti Glassell, 1933, and C. politus Smith, 1870 from the eastern and southeastern Pacific, respectively. All of these species are obligatory symbiont of slipper limpets of the molluscan family Calyptraeidae.…”

Larval development of Calyptraeotheres garthi (Fenucci, 1975) (Brachyura, Pinnotheridae) described from laboratory-reared material, with notes of larval character use on Pinnotheridae systematic

Calyptraeotheres garthi (Brachyura, Pinnotheridae) is a pinnotherid crab that lives in association with some species of Crepidula sp. (Calyptraeidae). The larvae of C. garthi were cultured under laboratory conditions (20°C and 35 PSU). Larval development from hatchling to megalopa took 30 days. Five zoeal stages and the megalopa are described and fully illustrated. The genus Calyptraeotheres consists only of four species. Larval characters were compared with the previous description of larvae from the southeastern Pacific species C. politus and with Tumidotheres maculatus a closely related pinnotherid crab. In addition, in light of recent molecular phylogeny of the family Pinnotheridae, we present a discussion about the Calyptraeotheres and its close related genera.
