RESUMO

Epibiosis is a common phenomenon, found in different taxa of aquatic animals. This relationship could occur as hyperepibiosis, when a basibiont being also an epibiont, providing a stable substrate for the hypersymbiont. Here we reported a ciliate-bryozoan-crustacean hyperepibiosis in Mandovi River mouth, Goa, West coast of India. We provided descriptions and characterization of the crab Atergatis sp., serving as basibiont for the bryozoan Triticella pedicellata (Alder, 1857), in turn colonized with (hyperepibionts) the ciliates Paracineta saifulae (Mereschkowsky, 1877) and Cothurnia ceramicola Kahl, 1933. Paracineta saifulae and Cothurnia ceramicola are reported here for first time from the Indian Ocean.

RESUMO

A compilation of the ciliated species found on freshwater and marine ostracods as epibiont or parasite (endobiont) has been carried out based on published records. The checklist includes the taxonomic position of each species of epibiontic and endobiontic ciliate, the species of basibiont ostracodes, the geographic zones and the bibliographic references where they were recorded. Altogether 7 suctorian, 29 peritrich, one apostome and one scuticociliatid species were listed. Two of recorded suctorian species are possible specific to marine ostracodes, whereas only one, Tokophrya sibirica to freshwater hosts. Fourteen species of peritrichs are likely specific to freshwater ostracodes, while three possible specific to marine ostracode hosts. Other suctorian and peritrich ciliate species were found on a variety of host taxa. One species of scuticociliatid was recorded as endobiont in ostracod.

RESUMO

The article deals with the report of 5 suctorians viz. Lecanophryella satyanandani (Santhakumari, 1986), Paracineta karunakarani Santhakumari, 1986, Ephelota gemmipara (Hertwig, 1876), Acineta foetida Maupas, 1881 and Pelagacineta sp. on marine pelagic ostracods Cypridina dentata (Müller, 1906) from new localities of the Arabian Sea. Diagnostic characters of Paracineta karunakarani are emended. Ephelota gemmipara (Hertwig, 1876) and Acineta foetida Maupas, 1881 are reported here for the first time on planktonic marine ostracods. Pelagacineta sp. is reported for the first time as epibiont on ostracods and from the Indian Ocean.

RESUMO

A worldwide checklist of the pontarachnid mites is provided based on published reports and original data. A total of 53 valid species of pontarachnid mites have been compiled, of which the genus Pontarachna includes 30 species, while 23 species belong to the genus Litarachna. The highest number of species (n=16) is reported from the marine province Tropical West of the Pacific Ocean. A deutonymph of Litarachna triangularis is reported here from Dongsha Atoll, Taiwan. Patterns of endemism and seemingly incomplete species distributional records are the result of a lack of intensive faunistic surveys in different parts of the world. The taxonomy of Pontarachnid mites will be improved by the use of mite-specific sampling methods and the application of molecular phylogenetics.

RESUMO

We present a checklist of the macrodasyidan Gastrotricha fauna of India derived from original articles and comprehensive monographies regarding the Indian Fauna. Taxa and specimens described from India are discussed with special attention to their status, especially those species previously known from distant geographic areas. A total of 43 species have been recorded from 4 States and 2 Union territories. A careful taxonomic assessment indicated that many species are in need of re-description as the reported anatomical traits are not sufficient to grant a modern, robust identification. The situation is particularly poor for two species (Macrodasys indicus Govindankutty Nair, 1969 and Paradasys lineatus Rao, 1980), which consequently, are considered here to be species inquirendae; moreover, the Indian records of Tetranchyroderma hystrix and T. massiliense reported from Kerala are doubtful and consequently the two species should not be included among the fauna of the Indian region until proper evidence is found. It is necessary to unravel the true identities of many Indian species through a comparison to topotypical material. We recommend that future comparisons between related species and conspecifics from different populations to include molecular sequence data.

RESUMO

The marine littoral mangrove mite fauna comprises members of the prostigmatid families of Halacaridae and Pontarachnidae, the mesostigmatid family Eutrachytidae, the astigmatid family Hyadesiidae and ten different families of Oribatida. The majority of this fauna is made up by the Halacaridae and Oribatida with 31 species each, the Pontarachnidae, Hyadesiidae and Eutrachytidae represent the minority with nine species altogether. So presently, 71 species are known to occur in mangrove ecosystems, more than half of which are exclusively associated with this habitat. Marine littoral mites have been reported from nearly all large mangrove ecosystems of the world, whereas species numbers clearly correlate with sampling effort. Therefore, the real diversity and distribution of mangrove mites is far from being complete and future investigations may reveal further new taxa being present in this environment that is seriously affected by anthropogenic activities.

RESUMO

Based on published records and original data, a list of the epibiont suctorian and peritrich ciliates (Ciliophora) on halacarid and hydrachnid mites is presented. Altogether 13 suctorian and 10 peritrich species from hydrachnid and halacarid mites were listed. From this list, six suctorian and one peritrich species have been reported from halacarid mites, while four suctorian and four peritrich species were found on hydrachnid mites determined up to species level. The remaining specimens were determined upto the generic level. The halacarid and hydrachnid species do not share any suctorian and peritrich species and some of the ciliate species are specific to certain taxonomic groups of the hosts.The host specificity of both suctorian and peritrich ciliates, localization on the host body and environment are discussed. Some ciliate species specific to hydrachnid mites prefer lotic or lentic habitats. In most cases, both suctorian and peritrich ciliates prefer only marine or only fresh water bodies. It was also mentioned that both suctorian and peritrich ciliates have not distinct preferences in localization on their host body.

RESUMO

Two new species of the marine water mite family Pontarachnidae, i.e., Litarachna enigmatica and L. antalyaensis are described from the Gulf of Antalya, Turkey. Litarachna enigmatica is unique in the postgenital sclerite having a pair of so-called wheel-like acetabula, a character so far found only in the females of Pontarachna. Litarachna antalyaensis is the second known species of the L. duboscqi-species group characterized by the absence of a ventral tubercle on P-2 and presence of a ventral tubercle on P-4, from the Mediterranean Sea. The new species can be separated from the widely distributed L. duboscqi in the glandularium-like structure posterior to the fourth coxal plates not fused with adjoining coxoglandularia 4.

RESUMO

The cumacean fauna of the Caribbean mesophotic reefs is remarkably rich but understudied. Herein, we present the description of 22 new species of the family Nannastacidae, including one from shallow reefs, 20 of them belonging to Cumella (Cumella) and two new species belonging to the subgenus Cumewingia. We have also included range extensions and new locations for ten previously known species of Cumella, two species in the genus Vaunthompsonia (family Bodotriidae) and one species in the genus Cubanocuma (family Nannastacidae). Taxonomic keys are provided for the western tropical Atlantic species of Cumella (Cumella) and Cumella (Cumewingia), separately for the adult males and females. Large sampling efforts and careful systematic studies, even in relatively well-characterized regions such as the Caribbean, can yield a surprising number of new discoveries. Our current findings emphasize our previous assertion that the mesophotic reefs are treasure troves of undiscovered benthic fauna and might be qualified as biodiversity hotspots.

RESUMO

The colonial peritrich ciliate Epistylis anastatica (Linnaeus, 1767) was discovered living as an epibiont on Mesocyclops isabellae Dussart & Fernando, 1988 collected from a pond in Andhra Pradesh state, India. This is the first report of Epistylis on this host, and a description of its morphological characteristics is provided. The biomass of colonies of E. anastatica relative to that of their hosts was relatively high, being greater than that of the host in some cases (8.11 mm3 vs. 1.14 mm3 or less), and this epibiotic burden has the potential to have an impact on the host's activities. Relationships between epibiotic peritrichs and microcrustaceans like cyclopoid copepods may be much more complex than previously supposed and merit more thorough investigation. Species of Epistylis are commonly found on cyclopoid copepods, but resources for taxonomic identification are limited and scattered; therefore, an annotated checklist of all species reported from cyclopoid copepods and a summary of the diagnostic characteristics of each one is provided as an aid to investigators. Some records of Epistylis spp. from cyclopoid copepods that are accompanied by documentary evidence are misidentifications, raising the suspicion that many other undocumented records also may be erroneous; therefore, it is suggested that authors provide supplementary descriptions and figures.

RESUMO

A new genus and two new species are described based on material collected from the mesophotic coral ecosystems of the U.S. Caribbean. The new genus Borikenella can be distinguished from other related genera such as Pseudaeginella, Paradeutella, Aciconula and Deutella by the combination of the following characters: pereopods 3 and 4 three-articulate, pereopods 5-7 six-articulate, mandible molar present, palp of the mandible with a setal formula 1-x-0, abdomen without appendages. The new species Liropus gurui, can be distinguished from the closely related L. japonicus mainly by the lack of anteroventral margin extended forward in pereonite 3, the lack of cleft and serration in the propodus of gnathopod 2, the longer pereopod 3 and the larger abdominal appendages.

RESUMO

A new species of the genus Boca Lowry & Stoddart, 1997 is described from a mesophotic coral ecosystem off southwestern Puerto Rico, in the Caribbean Sea. The new species is easily recognized from the others in the genus mainly by the following characters: (1) maxilliped, inner plate with 2 long apical simple setae; palp, articles slender, subequal in length; (2) gnathopod 1, propodus slightly elongate, about 2.5 × longer than wide, and palm extremely acute, quite long and distinctly demarked by a robust seta at the palmar corner; (3) gnathopod 2, carpus slightly elongate, about 3.7 × longer than wide; (4) pereopod 5, basis widely expanded posteriorly, posterior margin rounded and smooth, and posteroventral lobe weakly developed. We also present a key to world species of Boca. This is the fifth species of Boca from world's oceans and the first record of the genus from Puerto Rico.

RESUMO

In a continuing effort to describe the cumacean fauna of Puerto Rico we describe three new species of Bodotriidae, a family that has never been reported from Puerto Rico before.  While finding and describing new microcrustacean species may not be an impossible task, if there is available taxonomic expertise, the currently described species were found in large numbers within a short distance from the Marine Laboratories of the University of Puerto Rico where the local reefs have been studied for over half a century, highlighting the large gaps that exist in our estimates of Caribbean marine diversity.  The three new species, Cyclaspis gurui sp. nov., Cyclaspis mariae sp. nov. and Vaunthompsonia budaii sp. nov. are reported from a fringing reef off La Parguera, southwest coast of Puerto Rico and Vaunthompsonia cristata Bate, 1858 represents a new record for Puerto Rico from the mesophotic reefs.

RESUMO

NEW RECORDS OF PONTARACHNID MITES (ACARI: Hydrachnidia) from the Caribbean island of Puerto Rico are presented. Litarachna lopezae sp. n., from substrata collected from Bajo de Sico, a mesophotic coral reef ecosystem in Mona Passage off Puerto Rico, is described as new to science. The new species was collected from nearly 70 m depth, the greatest depth from which pontarachnid mites have been found until now. In addition, a Litarachna sp. was also found in association with the tube of the polychaete Sabellastarte magnifica (Shaw, 1800) at the shallow waters of north Puerto Rico.

RESUMO

Examination of substrata from the mesophotic reefs of Mona Island, Puerto Rico yielded 3 new species of cumaceans, all from the family Nannastacidae: Cumella achimae sp. nov., C. victoriae sp. nov. and Nannastacus craciuni sp. nov. The 3 new species bring the total of new cumacean taxa described from the mesophotic reefs of US Caribbean to 9, highlighting the potential of mesophotic reefs as a biodiversity hotspot. For the first time we report the genus Nannastacus from the Caribbean Sea.

RESUMO

Water mites (Hydrachnidia) occur sporadically in the gut of freshwater fishes. In this study, nine water mite items were found in the gut contents of the fish Botia dario (Hamilton, 1822) (Botiidae) collected in a floodplain wetland (beel) in the river island Majuli, Assam, India. Torrenticola episce is described as new to science; Torrenticola haliki Pesic & Smit 2010, Monatractides oxystomus (K. Viets, 1935) and Hygrobates cf. sinensis Uchida & Imamura, 1951, are reported for the first time from India.

RESUMO

Based on a revision of available literature on the Indian Cladocera (Crustacea: Branchiopoda), we present an updated checklist, with taxonomical updates and comments for all taxa recorded since the start of research of this group in the country since 1860. We have listed a total of 137 valid taxa, of which most records belong to species groups that need revision worldwide. The situation in Indian Cladocera taxonomy is, at present, insufficient for realistic conclusions on biodiversity, ecology and biogeography. We list suggestions for an improvement of the current situation.
