Chordatortilis crassicauda Mendonça et Rodriguez, 1965 (Spirurida, Acuariidae) in wren Troglodytes troglodytes (Passeriformes) in Europe: a new host and geographical record

IThe nematode Chordatortilis crassicauda Mendonҫa et Rodriguez, 1965 (Nematoda, Acuariidae)had previously been recorded only one time, in Brazil, as a parasite of T. musculus musculus Naumann.Thus the record of this species in Poland, in Europe, on another continent and in a different species of the genus Troglodytes, is worthy of presentation. The aim of the study is to document the resence of Chordatortilis crassicauda (Nematoda, Acuariidae) in the Wren Troglodytes troglodytes. Four Chordatortilis crassicauda individuals (three female and one male) were found between the proventriculus and muscular stomach of one T. troglodytes individual (adult female) collected in the village of Wicie on the Baltic Coast (north-western Poland) on 28 April 2013. The Wren is a new hostrecord for C. crassicauda. The fact that C. crassicauda had not previously been recorded in Europe may indicate that it is a rare species, specific to birds of the genus Troglodytes, which seldom undergo necropsy.
