New occurrences and host records for two species of parasitic isopods (Isopoda, Cymothoida, Bopyridae) associated with caridean shrimps (Decapoda, Caridea) from Brazil

Molecular features ofProbopyrussp. (Isopoda: Bopyridae) from Brazilian Amazonia and the parasitism of inland populations ofMacrobrachium amazonicum(Decapoda: Palaemonidae)

“…Ribeiro et al . (2019) also reinforce the need for molecular data to delimit the different species of the group and determine whether P. pandalicola is a single, widely dispersed species or a complex of cryptic species. The use of COI sequences was suggested by the authors and the present work has done that by analysing COI sequences obtained from different populations of Probopyrus species.…”

“…Based on the available data (Odinetz-Collart, 1988, 1990; Corrêa et al ., 2018), it would be reasonable to assume that the species found in the coastal populations is P. bithynis , given that the inland population appears to represent a new species of Probopyrus . Probopyrus bithynis presents differences in the larval morphology that can be used to distinguish this species from other Probopyrus taxa (see Dale and Anderson, 1982), in addition to some of the traits of the adult female (see Ribeiro et al ., 2019). As larvae were not collected in the present study and the research team has limited practical experience with the morphology of Probopyrus species, it was not possible to provide a more conclusive diagnosis of the morphology of the specimens collected here.…”

“…Ribeiro et al . (2019) recently recorded the occurrence of P. cf. pandalicola in the Brazilian state of Bahia and provided insights into the morphology of the females and distinctions from the description of Markham (1985), while also emphasizing the need for molecular data and the analysis of the larval morphology for more reliable identification of the species.…”

“…One bopyrid genus, Probopyrus , includes isopods that are typically ectoparasites in the branchial chamber of paleomonid prawns (Masunari et al ., 2000). The species of this genus include P. bithynis Richardson, 1904, P. buitendijki (Horst, 1910), P. floridensis Richardson, 1904, P. markhami Román-Contreras, 1996, P. pacificensis Román-Contreras, 1993 and P. pandalicola (Packard, 1879), which are known to parasitize prawns of the genera Macrobrachium , Palaemon and Palaemonetes (Lemos de Castro, 1974; Masunari et al ., 2000; Román-Contreras, 2004; Brinton and Curran, 2015 a ; Gopalakrishnan et al ., 2017; Ribeiro et al ., 2019; de Barros et al ., 2021).…”
