Abstract

ANAGUANO-YANCHA, Fernando  and  PILATASIG, Ana Lucía. New records and hosts of the isopod Telotha henselii (Isopoda: Cymothoidae) in Ecuadorian Amazonia. Biota colombiana [online]. 2022, vol.23, n.1, e202.  Epub Feb 09, 2022. ISSN 0124-5376.  https://doi.org/10.21068/2539200x.920.

In Ecuador, knowledge of isopod parasitism on fish is scarce. To date, only four species of this order are known to parasitize fish in the Ecuadorian Amazon. Here we present the first infestation records of Telotha henselii on loricariids in the Ecuadorian Amazon region, based on specimens collected in the Quimi River, southeast of the country. Telotha henselii is a hematophagous ectoparasite, located mainly in the gill cavity or in the musculature of fish. Parasitic intensity varied from one to two isopods per host and the prevalence was 16.6 % in Chaetostoma breve and 12.5 % in Chaetostoma carrioni.
