Ectoparasite Fauna

Abstract Despite being a bird with a broad and extensive distribution in Chile, the black-chinned siskin, Spinus barbatus Molina, 1782 is not well studied in relation to its parasites. This paper aims to describe the ectoparasite fauna of S. barbatus in central and southern Chile. A total of 125 individuals caught with mist nets were examined alive; a total of 22 parasites were found dead and were exposed to parasit autopsy. The extracted parasites were preserved in 70% alcohol for subsequent mounting and identification. Ectoparasites were found in 56 black-chinned siskins (38%); 48 of them (33%) had 870 mites – 680 feather mites (Astigmata: Analgoidea) were identified as Proctophyllodes spini, 167 as Knemidokoptes jamaicensis, 19 as Strelkoviacarus critesi, and one as Analges passerinus. Moreover, three mites were chiggers belonging to the tribe Schoengastiini (Prostigmata: Trombiculidae). In 21 birds (14%), 54 lice were found, 21 of which were identified as Philopterus roehreri, 18 as Myrsidea serini, and 15 as Ricinus carolynae. Endoparasites were not found in the necropsied individuals. All of the parasites that were found represent new records for Chile, and they also serve as new records of host–parasite associations for S. barbatus.

Abstract With the aim to identify the parasite fauna of plumbeous rail, Pardirallus sanguinolentus (Aves: Rallidae) in Chile, 26 carcasses were parasitologically necropsied. The present study revealed the presence of 14 species of parasites (inverse Simpson index = 4.64; evenness = 0.332), including ectoparasites: feather mites: Analloptes megnini , Grallobia sp., Grallolichus sp., Megniniella sp., and Metanalges sp.; the feather lice Pseudomenopon meinertzhageni, Rallicola andinus, and Fulicoffula sp.; and six species of gastrointestinal helminths: Heterakis psophiae, Porrocaecum ardeae, Tetrameres sp., Capillaria sp., Diorchis sp., and Plagiorhynchus sp. The relatively high parasite richness that was found could be attributed to the highly favorable conditions of wetlands for parasite development. All parasites found, except feather lice, are new records for plumbeous rail. A checklist of parasites for plumbeous rail is presented.

New populations of the Critically Endangered anuran species Alsodes vanzolinii (Donoso-Barros 1974) were discovered during two field surveys at Nahuelbuta Range, Biobío region, southern Chile. Adult specimens have not been reported since the original description of the species heretofore. The new records provided herein extend the latitudinal limit of what was previously thought to be the only population of the species 40 km to the southwest, and the altitudinal limit from 25 m a.s.l. to 700 m a.s.l.

This paper is an updated supplement to the host-parasite catalog of world Dryinidae published by Guglielmino and Olmi (1997). The authors give 157 new records of relationships between Auchenorrhyncha and Dryinidae, including 109 records listed in various papers and 48 new records.

We present the results of our investigation of feather mites (Astigmata) associated with non-passerine birds in Brazil. The studied birds were obtained from roadkills, airport accidents, and from capitivity. Most ectoparasites were collected from bird specimens by washing. A total of 51 non-passerine species from 20 families and 15 orders were examined. Of them, 24 species were assessed for feather mites for the first time. In addition, 10 host associations are recorded for the first time in Brazil. A total of 101 feather mite species were recorded, with 26 of them identified to the species level and 75 likely representing undescribed species; among the latter samples, five probably represent new genera. These records allowed the first inference about the host and mite association of many species, as well as the first discussion about the geographical distribution of some feather mite taxa along the host distribution.

Ectoparasite Fauna

SUMMARYPhylogenetic and geographical overlaps in host distributions influence the compositional similarity of ectoparasite fauna in a host–parasite system. In these systems, hosts that are more closely related (phylogenetically) are expected to share more parasitic species than more distantly related hosts. Similarly, hosts sharing a larger geographical distribution overlap are expected to have similar ectoparasites. This study investigated the influence of phylogeny (divergence time) and geographical overlap of some neotropical sigmodontine rodent species on the similarities among their ectoparasite fauna (Mesostigmata and Siphonaptera), using a partial Mantel test. Divergence time was the only significant factor that influenced the similarity among the ectoparasites, when mites and fleas were analysed together. Host species that had diverged more recently displayed ectoparasite fauna that were similar. The similarities of the flea species showed similar results in both separate and joint analyses, but neither phylogenetic nor geographical overlap influenced the similarity in mite species. Fleas were shown to be more host-specific than were mesostigmate mites, probably because of the increased influence of host phylogeny.

The mystacocarid Ctenocheilocaris galvarini is a member of the intertidal meiofauna in exposed sandy beaches along the coast of Chile. Originally described by Dahl (1952) from sub-tidal sediment off Isla Guafo, the only other published record is from semi-fine intertidal sand in Las Cruces. This paper presents a variety of new records of C. galvarini based on both quantitative and qualitative sampling of the coast of Chile between 18°S and 54°S. Ctenocheilocaris galvarini is found primarily in southern Chile, south of 32°, in the intertidal zone of intermediate beaches, in fine sand (Wentworth scale) most likely distributed between the level of the water-table and the surface, but avoiding dry sand.

Abstract To describe the parasitic community of the Magellanic Horned Owl, Bubo magellanicus (Aves, Strigiformes), 19 carcasses from central Chile were analyzed. Ectoparasites were collected through plumage inspection, while endoparasites were collected through traditional techniques of parasitological necropsy. Sixteen owls were infected with at least one species of ectoparasite (84.21%) or endoparasite (31.58%). Eleven of 19 birds (57.89%) harbored feather mites of the three species Pandalura cirrata (42.11%), Glaucalges attenuatus (47.37%), and Kramerella sp. (10.53%), whereas 16 individuals (84.21%) harbored the chewing louse Strigiphilus chilensis. Only six birds (31.58%) were infected with helminths; the nematodes Capillaria tenuissima (26.32%) and Dispharynx nasuta (5.26%); the acanthocephalan Centrorhynchus spinosus (5.26%); and the trematode Neodiplostomum sp. (5.26%). Apart from S . chilensis, all parasites comprised new records for B . magellanicus.
