Abstract

Birds in the Huinay area, Los Lagos region, Chile, were studied for parasites. Here we report 2 new genera and species of the family Dilepididae (Cyclophyllidea) found in common local passerines: Janinelliapeebeehigen. n., sp. n. was found in Elaeniaalbiceps (Tyrannidae) and Huinaylepiselegansgen. n., sp. n. was found in Aphrasturaspinicauda (Furnariidae). Other dilepidid parasites are reported for the first time from Xolmispyrope (Tyrannidae) and from 2 species of Rhinocryptidae. Cotylorhipissureshi Jadhav & Shinde, 1981 is considered a species inquirenda. The very high diversity and endemism of the observed cestode fauna in the Valdivian temperate rain forests is noted.

Highlights

Chile is home to a very rich avifauna comprising more than 460 species (Jaramillo et al 2003)

Summary

Introduction

Chile is home to a very rich avifauna comprising more than 460 species (Jaramillo et al 2003). Babero et al 1981; Torres et al 1991; González-Acuña et al 2017), very little is known of the cestode fauna of birds in this country. The diversity and novelty of this parasitic fauna is surprisingly high: all the parasite taxa recovered are new for Chile and several are new for science. Two earlier contributions based on this material described a new hymenolepidid genus from Trochilidae (Widmer et al 2013) as well as a new species of the genus Anonchotaenia (Paruterinidae) from the tyrant flycatcher Elaenia albiceps (Tyrannidae) (Phillips et al 2014)
