Proposal of TiddErgasilus gen. nov. (Ergasilidae: Cyclopoida) for T. iheringi comb. nov. from the gills of Hoplias malabaricus (Erythrinidae: Characiformes) from Brazil
Zoologia, 2018Co-Authors: Taísa Mendes Marques, Walter A. BoegerAbstract:Ergasilus von Nordmann, 1832 is the type and the most speciose genus of Ergasilidae, with more than 150 valid species. The first species of this genus, Ergasilusiheringi Tidd, 1942, was described from the Neotropical Region, from the gills of Hopliasmalabaricus (Bloch, 1794). Since then, 35 new species of Ergasilidae have been described from the Neotropics. However, a reanalysis of the available type specimens of E.iheringi revealed features that suggest that it represents a lineage independent from Ergasilus. Consequently, we propose TiddErgasilus gen. nov. (Ergasilidae: Cyclopoida) to accommodate T.iheringi (Tidd, 1942) comb. nov. The species was re-examined and redescribed based on available type specimens. TiddErgasilus gen. nov. is characterized by species with exopod of leg 4 2-segmented; antenna small and robust, with a short second segment (approximately three times shorter than the first segment), and claw with a unique morphology (short, recurved with a sub-proximal indentation in the inner margin). A phylogenetic analysis, based on a matrix of 15 taxa and 16 morphological characters in PAUP* software 4.0a152, resulted in 15 equally parsimonious trees. Based on this analysis, TiddErgasilus is closely related to a group composed of Neotropical species of Ergasilus – sharing with them antennule with 6-segments. When the highly homoplastic character “number of segments in the antennule” is removed from the analysis, TiddErgasilus forms a polytomy with the clade of genera of the former Vaigamidae, Ergasilus, and the clade RhinErgasilus+BrasErgasilus+Pindapixara.

Ergasilus turkayi n sp copepoda cyclopoida ergasilidae a gill parasite of serrasalmus hollandi jegu 2003 characiformes serrasalmidae from the paragua river bolivia
Nauplius, 2017Co-Authors: Taísa Mendes Marques, Luan Clebsh, Leslie Cordova, Walter A. BoegerAbstract:A new parasitic copepod species, Ergasilus turkayi n. sp., found on the gills of the Holland’s piranha, Serrasalmus hollandi Jegu, 2003, in the Paragua River, Bolivia, is described based on 10 adult females. The new species presents a triangular-shaped cephalothorax, spinules on interpodal plates and aesthetascs on antennule - two aesthetascs on the sixth, and one aesthetasc plus two setae on the fifth segment. Additionally, the second abdominal somite of E. turkayi n. sp. bears an anal pseudoperculum, a dorsal and elongate projection which is usually absent or vestigial in poecilostome families within the Cyclopoida but that was never reported in species of Ergasilidae.

two new species of Ergasilus nordmann 1832 copepoda ergasilidae and a redescription of Ergasilus salmini thatcher brazil sato 2008 from salminus brasiliensis cuvier and s franciscanus lima britsky teleostei characidae in brazil
Systematic Parasitology, 2015Co-Authors: Taísa Mendes Marques, Walter A. Boeger, Marilia De Carvalho BrasilsatoAbstract:Three species of Ergasilus Nordmann, 1832 are reported from the gills of Salminus spp. in Brazil. Ergasilus salmini Thatcher & Brazil-Sato, 2008 from Salminus brasiliensis Cuvier is redescribed, based on examination of paratypes. The study revealed morphological differences from the original description, especially in the morphology of the cephalothorax and the ornamentation of antenna, antennule and legs. Ergasilus lacusauratus n. sp. described from S. brasiliensis in lake Lagoa Dourada (Parana) differs from the only known species from this host group, E. salmini, in the shape and size of the cephalothorax and the general morphology of the egg-sacs. Ergasilus sinefalcatus n. sp. from S. franciscanus Lima & Britsky in River Sao Francisco (Minas Gerais) closely resembles E. pitalicus, E. coatiarus and E. leporinidis in the lack of a pectinate seta on the first exopodal segment, a feature common in species of Ergasilus in the Neotropics. Ergasilus sinefalcatus n. sp. differs from these species in the presence of a spiniform process on the coxae of legs 2, 3 and 4, an ornament never reported from freshwater species of Ergasilus in South America.

Copepods and larvae of nematodes parasitizing (correction of parasiting) the white mullet Mugil curema (Valenciennes, 1836): indicators of anthropogenic impacts in tropical coastal lagoons?
Environmental monitoring and assessment, 2006Co-Authors: E J Fajer-avila, A García-vásquez, H Plascencia-gonzález, J Ríos-sicairos, L M García-de La Parra, M Betancourt-lozanoAbstract:The relationship between parasites and environmental stress were studied in two tropical coastal lagoons of Northwest Mexico: Urias estuary (highly polluted) and Teacapan estuary (slightly polluted). Metazoan parasites were examined in 292 white mullet (Mugil curema) specimens collected bimonthly during a year from both systems. Haliotrema mugilinus, Metamicrocotyla macracantha, Ergasilus sp., Caligus sp., Holobomolochus sp., and Lernaeopodidae were found in gills, while Contracaecum sp. larvae III was found liver, hepatic portal vein and kidneys. Ecological indices were influenced by the slightly higher number of parasitic species in Urias compared to Teacapan, as well as the clear dominance of two species: Ergasilus sp. and Contracaecum sp. in both systems. In fact, Ergasilus sp. showed considerably higher abundance in Urias, possibly indicating that its success was a result of adverse conditions affecting the host, while Contracaecum sp showed higher abundances in Teacapan, suggesting that the environmental conditions occurring in Urias could have produced negative impacts on the nematode's infective potential.

Parasite Community of Cichla kelberi (Perciformes, Cichlidae) in the Três Marias Reservoir, Minas Gerais, Brazil
Revista Brasileira De Parasitologia Veterinaria, 2014Co-Authors: Michelle Daniele Santos-clapp, Marília Carvalho Brasil-satoAbstract:A total of 112 specimens of yellow peacock bass, Cichla kelberi, were collected in the Tres Marias Reservoir, upper Sao Francisco River, State of Minas Gerais, between 2004 and 2005. Twelve species of parasites were collected: two species of ectoparasites (the monogenetic Gussevia sp. and the copepod Ergasilus sp.); and ten species of endoparasites, including four species of adult endoparasites: the cestodes Proteocephalus macrophallus and P. microscopicus, and the nematodes: Capillostrongyloides sentinosa and Rhabdochona acuminata, and six species of larval endoparasites: the metacercariae of Austrodiplostomum compactum and the nematodes: Hysterothylacium sp., Contracaecum sp. Type 1, Procamallanus (Spirocamallanus) inopinatus, Spiroxys sp., and Goezia sp.. A significant positive correlation in the abundance of the two adult endoparasites species, P. macrophallus and P. microscopicus, may indicate that such associated species had the same ecological requirements. The positive correlations between the prevalence of the larval endoparasites, Hysterothylacium sp. and A. compactum, may indicate that there was opportunism for the two generalists species. Ergasilus sp., C. sentinosa, R. acuminata and Hysterothylacium sp. were recorded for the first time in C. kelberi, and this increased their list of known hosts. In addition, both proteocephalid species and C. sentinosa can extend their known biogeographical distribution to the Tres Marias Reservoir.

Ergasilussalmini sp. nov. (Copepoda: Ergasilidae) a branchial parasite of "dourado", Salminus franciscanus from the upper São Francisco River, Brazil
Revista Brasileira De Zoologia, 2008Co-Authors: Vernon E Thatcher, Marília Carvalho Brasil-satoAbstract:Ergasilus salmini sp. nov. a branchial parasite of the "dourado", Salminus franciscanus Lima & Britski, 2007, from the upper Sao Francisco river, Minas Gerais State, Brazil, is described based on female specimens. The new species has a serrate, curved seta on the first exopod as do most of the known South American species of the genus. Other than that, it does not closely resemble any known species of this genus. Many of the known ergasilids have head, and first two thoracic segments completely fused to form a cephalothorax. In the new species, the head is incompletely fused, the first thoracic segment is fused, but thoracic segment two is free. Ergasilus hydrolycus Thatcher, Boeger & Robertson, 1984, also has a free second thoracic segment but in that species the head is completely fused and the third abdominal segment is the longest. In the new species, the third segment is the shortest of the three. Also, the new species is smaller averaging 691 x 207 µ m compared to 784 x 278 µ m for E. hydrolycus. The latter species has a two-segmented fourth endopod whereas in the new species this structure is three-segmented. In addition, the new species is from a different host and a separate river system.
