Abstract

A new feather mite species, Dolichodectes hispanicus sp. n. (Astigmata: Proctophyllodidae), is described from the Melodious Warbler Hippolais polyglotta (Vieillot) (Passeriformes: Acrocephalidae) in Spain. The new species is closest to the type species of the genus, D. edwardsi (Trouessart, 1885) from the Grear Reed-Warbler Acrocephalus arundinaceus (Linnaeus) (Acrocephalidae). Adults of D. hispanicus differ from those of D. edwardsi by dimensional characteristics, in particular, by having shorter aedeagus that does not extend to the anal suckers in males and shorter hysteronotal shield in females. Tritonymphs of D. hispanicus are much more distinctive and differ from those of D. edwardsi by having the prodorsal shield covering all the prodorsum, the hysteronotal shield occupying about three quarters of the hysterosoma, and idiosomal setae h3 being filiform. The morphological description of the new species is augmented by sequence data from the mitochondrial cytochrome c oxidase subunit I gene fragment (COI).

Highlights

The feather mite genus Dolichodectes Park et Atyeo, 1971 (Astigmata: Proctophyllodidae) was established in a generic revision of the subfamily Pterodectinae (Park and Atyeo 1971), and to date it has included eight species (Mironov and Fain 2003, Mironov et al 2010, 2012)
Mites of the genus Dolichodectes have been recorded from representatives of seven passerine families distributed in the Old World: Acrocephalidae, Phylloscopidae, Platysteiridae, Muscicapidae, Turdidae, Ploceidae (Passeroidea) and Monarchidae (Corvoidea)
Hernandes and Valim (2006) constructed a key to species of Dolichodectes and described a new species, D. neotropicus Hernandes et Valim, 2006, from a cotinga host (Passeriformes: Cotingidae) in Brazil. These authors (Valim and Hernandes 2009) found out that this species belonged to the generic complex of Pterodectes Robin, 1877 and it was removed to a separate genus Berladectes Valim et Hernandes, 2009

Summary

Introduction

The feather mite genus Dolichodectes Park et Atyeo, 1971 (Astigmata: Proctophyllodidae) was established in a generic revision of the subfamily Pterodectinae (Park and Atyeo 1971), and to date it has included eight species (Mironov and Fain 2003, Mironov et al 2010, 2012). Specimens of Dolichodectes edwardsi, used for comparison in the differential diagnosis, were collected from its type host, the great reed-warbler Acrocephalus arundinaceus (Linnaeus) (Acrocephalidae), in the same locality where the type material of the new species was collected (Doñana National Park, Huelva, Spain).
