Helminths of some tree frogs of the families Hylidae and Phyllomedusidae in an Atlantic rainforest fragment,Brazil

Despite the fact that Brazil is the most-studied country regarding helminths of amphibians, only around 8% of Brazilian anurans have had at least one study made of their helminth fauna. Therefore, the aim of this study was to describe the helminth community of nine species of Atlantic Rainforest anurans of two different families, eight of them with no previous study, and six of which are endemic to Brazil. The analysed hosts for their parasites were: Dendropsophus minutus (n = 48), Scinax auratus (n = 36), D. branneri (n = 33), D. elegans (n = 26), Hypsiboas albomarginatus (n = 22), Pithecopus nordestinus (n = 19), D. decipiens (n = 12), D. haddadi (n = 11) and S. x-signatus (n = 11). A total of 781 helminths were collected from 106 (48.6%) of 218 analysed hosts, 656 Centrorhyncus sp. cystacanths and 125 nematodes: 76 adults (25 Cosmocerca sp.; three Cosmocerceidae gen. sp.; 20 Cosmocerca parva, 20 Cosmocercella phyllomedusae, five Aplectana sp., two Oswaldocruzia sp. and one Rhabdias sp.), 43 encysted larvae (nine Porrocaecum sp. and 34 Brevimulticaecum sp.) and six Physaloptera sp. larvae. Anurans may display many roles within the helminth life cycles, as they act as both predator and prey to a wide variety of animals. Consequently, we have found helminths that use anurans as definitive, intermediate and paratenic hosts. Opposing other surveys in which nematodes are the most prevalent and abundant parasites, acanthocephalans were the most prevalent taxa. These findings highlight the lack of knowledge regarding the helminth fauna of anurans and reveal many gaps with respect to their infection patterns in amphibians.

Twenty-eight new host records and two new locality records are reported. The biogeography of the recovered helminths is discussed.     

Two new genera and five new species of the feather mite subfamily Proctophyllodinae (Astigmata: Proctophyllodidae) from suboscine birds in Brazil

Two new genera and five new species of feather mites of the family Proctophyllodidae are described from passerine birds from Brazil: Tyranniphyllodes pitangi gen. n., sp. n. from Pitangus sulphuratus (Tyrannidae); Atrichophyllodes delalandi gen. n., sp. n. from Corythopis delalandi (Tyrannidae); A. mentalis gen. n., sp. n. from Dysithamnus mentalis (Thamnophilidae); Anisophyllodes candango sp. n. from Elaenia chiriquensis (Tyrannidae); and Platyacarus sittasomi sp. n. from Sittasomus griseicapillus (Dendrocolaptidae). The discovery of these taxa might give data for a better understanding of the evolution of the family Proctophyllodidae in general and the dispersion of these mites on passerines in South America in paricular.     

A new genus and three new species of free‐living marine nematodes from the Yellow Sea,China

One new genus, Paramphimonhystrella gen. nov., and three new species of free‐living marine nematodes in this genus, P. elegans sp. nov., P. minor sp. nov., and P. sinica sp. nov., are described and illustrated from the Yellow Sea, China.

Paramphimonhystrella elegans sp. nov. is characterized by ovoid amphids and spicules with a small hook at distal end and cylindrical part of tail shorter than conical part. Paramphimonhystrella sinica sp. nov. is characterized by circular amphids, wide buccal cavity, spicules with blunt tip, and cylindrical part of tail longer than conical part. Paramphimonhystrella minor sp. nov. differs from the other two species by its smaller body (shorter than 800 µm), circular amphids, and spicules with sharp tip. The type species of this new genus is P. elegans gen. nov. and sp. nov. Types are deposited in the College of Marine Life Sciences, Ocean University of China.

Description of four new species of the Cirolana ‘parva group’ (Crustacea: Isopoda: Cirolanidae) from Thailand,with supporting molecular (COI) data

Four new species of the Cirolana ‘parva group’ from shallow coastal habitats in Thailand are described: Cirolana andamanensis sp. nov. and C. phangnga sp. nov., from the Andaman Sea, and C. siamensis sp. nov. and C. thailandica sp. nov. from the Gulf of Thailand. Molecular (The cytochrome oxidase subunit I gene) analysis incorporating taxa from the Cirolana ‘tuberculate group’ shows a monophyletic clade (Bayesian inference = 1 and maximum likelihood = 100%) within the Cirolana ‘parva group’ with two clades reflecting morphological characters. Cirolana andamanensis sp. nov. with antennula peduncle articles 1 and 2 entirely fused; male pereopod 1 without a setal fringe; uropod peduncle ventrolateral margin with 1 sensory seta. Cirolana phangnga sp. nov., C. siamensis sp. nov. and C. thailandica sp. nov. share the morphological characters of antennula peduncle articles 1 and 2 distinctly articulated; pereopod 1 in male with a setal fringe on the carpus and propodus; uropod peduncle ventrolateral margin with 3 sensory setae. Uncorrected p-distances strongly support the separation of these species, originally based on morphology, and show that the highest value of 32.1% is between C. thailandica sp. nov. and C. andamanensis sp. nov., while the lowest value of 22.5% is between C. phangnga sp. nov. and C. siamensis sp. nov.     

A new genus and two new species of cave-dwelling Misophrioid copepods from the Balearic Islands (Mediterranean)

Speleophriopsis balearicus n. gen., n. sp., and Speleophria gymnesica, n. sp. are described from the flooded coastal karst of the Balearic Is. Two existing species of Speleophria are transferred to the new genus. Speleophriopsis scottodicarloi (Boxshall and Iliffe), new combination, occurs on Bermuda (Atlantic) and S. campaneri (Boxshall and Iliffe), new combination, in the Palau Archipelago (Indo-West Pacific). The type species of Speleophria is known only from caves on Bermuda. Both genera are noteworthy for displaying the most primitive condition known in copepods of the allobasis of maxilla (setal formula 5,3), and of the male antennule which, in Speleophriopsis n. gen., is geniculate but exhibits a 27-segmented condition. They inhabit cave waters with salinities in excess of 18‰., avoiding lower salinity inland groundwater habitats. A Tethyan relict status is proposed for both taxa.     

New genera and species of the Synchelidium group (Amphipoda: Oedicerotidae) from Asia-North Pacific

Four new species and two new genera belonging to the family Oedicerotidae are reported from Korea and Vietnam. Two new genera, Orthomanus and Imbachoculodes are described, with three new species, namely Orthomanus koreanus gen. et sp. nov., Imbachoculodes namhaensis gen. et sp. nov. and Imbachoculodes vietnamensis gen. et sp. nov. The monotypic genus Orthomanus is characterized by the very short carpi and transverse palms of gnathopods 1 and 2, the reduced dactyli on pereopods 3–6, and the greatly enlarged distolateral spine-tooth on the outer plate of maxilla 1. Imbachoculodes has slender gnathopods 1 and 2 with elongated carpi, pereopods 3 and 4 with elongated dactyli, and a narrow basis of pereopod 7. The fourth new species, Sinoediceros hwanghaensis sp. nov. has a greatly reduced flagellum on antenna 2, a broadened meri on pereopods 3 and 4, and an elongated maxilliped outer plate. Keys are provided to 1) the North Pacific genera of the Synchelidium group, 2) species of Imbachoculodes, and 3) species of Sinoediceros.
