A New Species

A redescription of Pagurus albus (Benedict, 1892) is presented together with a description of a new species of hermit crab, Pagurus pseudoalbus sp. n., from the Pacific coast of Costa Rica. Pagurus pseudoalbus sp. n. differs from P. albus and P. perlatus by the length of antennal acicles, which do not exceed the distal margin of the 4th antennal segment, whereas in the latter two species, the antennal acicles exceed the 4th antennal segment; the antennular peduncle is proportionally longer than the ocular peduncle in the new species compared to P. perlatus, but shorter than in P. albus; the palm of the right cheliped in P. pseudoalbus sp. n. is 1.3 times as long as broad, while in P. albus and P. perlatus it is 1.0 and 1.4 times as long as broad, respectively. Including the new species, the genus Pagurus in the Eastern Tropical Pacific currently includes 16 species.

A New Species

A partir de dos ejemplares recolectados en la costa pacífica de Costa Rica y Panamá, se describe una nueva especie Trapania inbiotica sp. nov., la cual se distingue por tener el cuerpo blanco con manchas rojas y rin6foros blancos con algunas manchas amarillas pequefias. La rádula está compuesta por 28 filas de dientes donde cada diente tiene de 21-25 dentículos y una cúspide cónica y larga situada cerca del lado exterior. Dos o tres de esos dentículos localizados en la parte interna de la cúspide son más pequefios que los otros. También están presentes de 1-3 dentículos en la parte externa de la cúspide. La armadura labial está compuesta por uncinos muy irregulares.

A New Species

The description of this single species is necessary to facilitate the publication of ongoing research conducted by Rita Vargas at the Museum of Zoology, University of Costa Rica, dealing with the associated microfauna. Presently 24 species of Leptogorgia have been reported for the eastern Pacific, 13 of which have been found in Costa Rica (Breedy & Cortés 2011). Although octocoral surveys have been conducted as part of biodiversity studies, there is no published information regarding the occurrence of this taxon in Golfo Dulce. Here we describe a new species of Leptogorgia and compare it with other Leptogorgia species with similar characteristics. Golfo Dulce is a bay located on the southern Pacific coast of Costa Rica. It is about 50 km long, 10–15 km wide, and covers an area of approximately 680 km². The inner part of Golfo Dulce has a maximum depth of slightly over 200 m with a 60 m deep sill at the opening to the Pacific Ocean (Cortés 1999). It has been considered a tropical fjord because of the bathymetry and the presence of anoxic deep waters (Cortés 1999, Svendsen et al. 2006). Specimens were collected by Scuba diving, preserved in 70% ethanol or air dried, and treated and identified following the current methodology (Breedy & Guzman 2002). The holotype and paratypes are deposited in the Museo de Zoología, Universidad de Costa Rica (MZUCR, formerly UCR), San José, P.O. Box 11501-2060, Costa Rica.

A New Species

Pleurothallis tenuisepala, a new species in subsection Acroniae, is described and compared to Pleurothallis luctuosa with which it has previously been confused. While the two species are superficially similar, they can be very easily distinguished by the size of the flowers, which are approximately 60 mm long in P. tenuisepala versus approximately 29 mm long in P. luctuosa, or the length of the sepals, which are approximately four-times the length of the petals in P. tenuisepala versus less than twice the length of the petals in P. luctuosa. The two species can also be discriminated by their nuclear internal transcribed spacer (nrITS) sequences. Pleurothallis tenuisepala occurs on Isla Gorgona off the Pacific coast of Colombia and on the western slopes of the Cordillera Occidental of the Colombian Andes, while P. luctuosa is restricted to the Cordillera de Tilarán of Costa Rica. Labellar micromorphology of both species is discussed in relation to possible pollination mechanisms. Key words: Acroniae, cryptic species, labellum, morphology, taxonomy
