New records of two species of parasitic isopods (Isopoda: Cymothoida: Bopyridae: Athelginae) associated with hermit crabs from the south Atlantic

Two species of bopyrid isopods from the subfamily Athelginae are recorded from new localities in northeastern Brazil. Parathelges foliatus Markham, 1972 was recorded for the first time from Brazil, in the state of Ceará, parasitising the hermit crab Clibanarius symmetricus (Randall, 1840). Pseudostegias atlantica Lemos de Castro, 1965 is recorded from the state of Ceará, parasitising Clibanarius antillensis Stimpson, 1859. Illustrations, species diagnosis and an updated distribution map are given for each species.

New records of the isopod Leidya distorta infesting the mangrove crab Ucides cordatus from South America / Novos registros de Leidya distorta infestando o caranguejo-ucá Ucides cordatus na América do Sul

The Neotropical region has a large diversity of crabs. However, the diversity of the parasites infesting these crustaceans is still poorly known. In this study, we recorded three new occurrences of the isopod bopyrid Leidya distorta on Ucides cordatus from Southern Brazil and North-Eastern Venezuela. Crabs were collected in mangroves of Venezuela (Cumaná) and Brazil (Cananéia and São Vicente). A total of 281 crabs were captured in these localities and dissected in the laboratory to verify parasitism by L. distorta. Three of these crabs were infested with L. distorta. Parasitic prevalences in the crabs were generally very low (1.1%), and differed according to localities: Cananéia (2.6%) and São Vicente (2.2%) were slightly higher than in Cumaná (0.5%). Here, we present new records of L. distorta infesting the mangrove crab U. cordatus from South America and reviewed the brachyuran that serve as host to L. distorta.(AU)

A região Neotropical tem uma grande diversidade de caranguejos. No entanto, a diversidade de parasitos infestando esses crustáceos ainda é pobremente conhecida. No presente estudo, foram registrados três novas ocorrências de Leidya distorta em Ucides cordatus no Sudeste do Brasil e no Nordeste da Venezuela. Os caranguejos foram coletados em manguezais da Venezuela (Cumaná) e do Brasil (Cananéia e São Vicente). Um total de 281 caranguejos foram capturados nessas localidades e dissecados no laboratório para verificar a presença de L. distorta. Apenas três caranguejos foram infestados com o bopirídeo Leidya distorta. A prevalência nos caranguejos foram muito baixa (1.1%), e diferiram de acordo com as localidades: levemente alta em Cananéia (2.6%) e São Vicente (2.2%), comparada com Cumaná (0.5%). Este estudo apresenta novas ocorrências de Leidya distorta infestando o caranguejo-uçá Ucides cordatus na América do Sul, bem como uma revisão dos braquiúros que servem de hospedeiro para Leidya distorta.(AU)
