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

Abstract

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.

Material examined: BRAZIL: Ceará: one female, Camocim, Estuário do Rio Coreaú (02°53’42”S, 40°51’31”W), coll. F.B. Ribeiro, 13/X/2008, identified by D. Roccatagliata and F.B. Ribeiro, 13/X/2008, (UFRGS 5970), infesting pleon of an ovigerous female of Clibanarius symmetricus (Randall, 1840) (5 mm CL; UFC 230).

Diagnosis:Female: cephalon spade-shaped in outline, eyes absent, barbula with three sharp projections on each side, pereopods all alike and with prominent coxal segments, pleon with distinct segments, exopodites of pleopods long and rounded at ends, pleotelson not set off. Males are unknown.

Remarks:Parathelges foliatus was described based on a female (TL 8.33 mm) from Trinidad, being reported only from the type-locality (Markham, 1972bMarkham, J.C. 1972b. Four new species of Parathelges Bonnier, 1900 (Isopoda, Bopyridae), the first record of the genus from the western Atlantic. Crustaceana, Supplement 3: 57-78. http://www.jstor.org/stable/25027409.
http://www.jstor.org/stable/25027409...
). The specimen examined here is morphologically similar to the material described by Markham (1972bMarkham, J.C. 1972b. Four new species of Parathelges Bonnier, 1900 (Isopoda, Bopyridae), the first record of the genus from the western Atlantic. Crustaceana, Supplement 3: 57-78. http://www.jstor.org/stable/25027409.
http://www.jstor.org/stable/25027409...
), showing the pereon with all segments well distinguished dorsally, marsupium closed ventrally, pleopodal exopodites on peduncles and with distal margins rounded (Fig. 1A, B). Additional morphological characters not mentioned in previous descriptions include: antennule with three articles and antenna with four articles (Fig. 1C, D), and pereopod 7 with dactylus embedded in the propodus (Fig. 1I). This is the first record of this species from Brazilian waters and second for the western Atlantic Ocean. In addition, this is the third genus of Athelginae recorded from Brazil; the genera AnathelgesBonnier, 1900Bonnier, J. 1900. Contribution à l’étude des épicarides. Les Bopyridae. Travaux de l’lnstitut Zoologique de Lille et du Laboratoire de Zoologie Maritime de Wimereux, 8: 1-478. from the state of Santa Catarina and Pseudostegias are known from the states of Ceará and Alagoas, respectively (Brasil Lima, 1998Brasil Lima, I.M. 1998. Malacostraca - Peracarida. Isopoda - Epicaridea. In: Young, P. (ed.). Catalogue of Crustacea of Brazil. Rio de Janiero: Museu Nacional, pp. 635-644.).

Representatives of the genus Parathelges infest diogenid hermit crabs of the genera Allodardanus Haig & Provenzano, 1965, Calcinus Dana, 1851, Clibanarius Dana, 1852 and Dardanus Paul’son, 1875 (Markham, 2003Markham, J.C. 2003. A worldwide list of hermit crabs and their relatives (Anomura: Paguroidea) reported as hosts of Isopoda Bopyridae. Memoirs of Museum Victoria, 60(1): 71-77.). Parathelges foliatus was described infesting the same host of our specimen, the hermit crab Clibanarus vittatus (Bosc, 1802). However, Negri et al. (2014Negri, M.; Lemaitre, R. & Mantelatto, F.L. 2014. Molecular and morphological resurrection of Clibanarius symmetricus (Randall, 1840), a cryptic species hiding under the name for the “thinstripe” hermit crab C. vittatus (Bosc, 1802) (Decapoda: Anomura: Diogenidae). Journal of Crustacean Biology, 34(6): 848-861.) established that populations of C. vittatus should be restricted to the southeastern coast of the United States and Gulf of Mexico. Specimens from the Caribbean to southern Brazil should be classified as Clibanarius symmetricus (Randall, 1840), which is therefore the identity of the host of P. foliatus. According to Markham (1972bMarkham, J.C. 1972b. Four new species of Parathelges Bonnier, 1900 (Isopoda, Bopyridae), the first record of the genus from the western Atlantic. Crustaceana, Supplement 3: 57-78. http://www.jstor.org/stable/25027409.
http://www.jstor.org/stable/25027409...
), species of Parathelges are usually found associated with shallow-water hosts, which agrees with our specimen collected attached to a hermit crab in the intertidal zone of an estuarine area.

Material examined: BRAZIL: Ceará: one female and one male, Paracuru, Pedra Rachada Beach (02°53’42”S, 40°51’31”W), coll. F.B. Ribeiro, identified by D. Roccatagliata and F.B. Ribeiro, 13/X/2008, (UFRGS 6669), infesting pleon of a male of Clibanarius antillensis Stimpson, 1859 (2.7 mm CL; UFC 506).

Diagnosis:Female: cephalon deeply inset in pereomere I and about two times as long as wide, eyes present, all pereomeres distinct, all pereopods similar in size, all pleomeres distinct and tapering posteriorly, lateral plates on pleomere V absent. Male: eyes present, pereon broadest at pereomere 6, all pleomeres fused, pleopods and uropods absent.

Remarks:Pseudostegias atlantica was described based on one mature female (TL 5.5 mm) and male (3 mm) from Mucuripe beach, Fortaleza, state of Ceará, and one immature female and male from Garça Torta beach, Maceió, state of Alagoas (Lemos de Castro, 1965Lemos de Castro, A. 1965. Crustáceos Isópodos Epicarídeos do Brasil. I: Descrição de uma espécie nova do gênero “Pseudostegias” Shiino (Isopoda, Bopyridae). Revista Brasileira de Biologia, 25: 105-108.). The specimen examined here is morphologically similar to the material described by Lemos de Castro (1965Lemos de Castro, A. 1965. Crustáceos Isópodos Epicarídeos do Brasil. I: Descrição de uma espécie nova do gênero “Pseudostegias” Shiino (Isopoda, Bopyridae). Revista Brasileira de Biologia, 25: 105-108.), showing the cephalon with anterior margin straight, dorsal region of cephalon concave with pereomeres 1-5 directed laterally forewards, all pereopods are similar in size, pleomeres distinct, lateral plates present in pleomeres 1-5 and pleopods with leaf-like endopodites and exopodites (Fig. 2). Regarding the male specimen, it is similar to the allotype of P. atlantica in having the cephalon of approximately two times as wide as long with rounded anterior margin and all pleomeres fused (Fig. 3); however, it differs in the absence of the dorsal carina on the pleotelson. It is very likely that the specimen analyzed by Lemos de Castro (1965Lemos de Castro, A. 1965. Crustáceos Isópodos Epicarídeos do Brasil. I: Descrição de uma espécie nova do gênero “Pseudostegias” Shiino (Isopoda, Bopyridae). Revista Brasileira de Biologia, 25: 105-108.) showed an artifact of preservation for this character. Additional morphological characters not mentioned in previous descriptions for the female include: antennule of three articles and antenna of six articles (Fig. 2C, D), oostegite 1 bilobed with anterior lobe subtriangular, posterior lobe with inner margin concave, oostegites 2-3 subrectangular and oostegites 4-5 subtriangular (Fig. 2E-I); and for the male, antennule of three articles and antenna of four articles (Fig. 3C, D), all pereopods subequal in size and shape (Fig. 3B), and pereopods 1 and 7 bears three setae in the distal margin of carpus (Fig. 3E, F). The barbula and maxilliped were not illustrated due to the condition of the material.

Pseudostegias is a genus of by pleonal parasites of diogenid hermit crabs of the genera Calcinus Dana, 1851, Clibanarius Dana, 1852, Diogenes Dana, 1851, Paguristes Dana, 1851; pagurid hermit crabs of the genus Strigopagurus Forest, 1995; and lithodid anomurans of the genus Hapalogaster Brandt, 1850 (Markham, 2003Markham, J.C. 2003. A worldwide list of hermit crabs and their relatives (Anomura: Paguroidea) reported as hosts of Isopoda Bopyridae. Memoirs of Museum Victoria, 60(1): 71-77.). All specimens used in the original description of P. atlantica were found associated to a host identified as Clibanarius sp. (Lemos de Castro, 1965Lemos de Castro, A. 1965. Crustáceos Isópodos Epicarídeos do Brasil. I: Descrição de uma espécie nova do gênero “Pseudostegias” Shiino (Isopoda, Bopyridae). Revista Brasileira de Biologia, 25: 105-108.). The specimens in our study were found infesting the hermit crab Clibanarius antillensis Stimpson, 1859 from Pedra Rachada Beach, Paracuru, state of Ceará. This new record is about 100 km from the previous record in this state.

Distribution: Western Atlantic: Brazil (states of Ceará and Alagoas) (Fig. 4).

CONCLUSION

The broad distribution of the host species on the Brazilian coast suggest the likelihood that their bopyrid parasites can also have a much wider distribution than currently reported in Brazil (Fig. 4). In addition, considering the current diversity of the Athelginae, three known species, and the Brazillian coastal extension, probably the diversity of the subfamily is still underestimated. Future surveys, in order to obtain more material, will allow the accurate identification of already known species and possible discovery of new taxonomic entities.
