A new quill mite Syringophiloidus plocei sp. nov. (Prostigmata: Syringophilidae) parasitizing ploceid birds (Passeriformes) in Gabon - a combined description using morphology and DNA barcoding.

A new species of quill mites (Syringophilidae) Syringophiloidus plocei sp. nov. parasitizing Ploceus cucullatus (St. Muller) (type host), P. aurantius (Vieillot) and P. nigerrimus (Vieillot) (Ploceidae: Passeriformes) in Gabon is described using external morphology and DNA barcode data (the mitochondrial cytochrome c oxidase subunit I sequences (COI) and D1-D3 region of the nuclear 28S rRNA gene). Females of S. plocei sp. nov. differ from S. pseudonigritae Glowska, Dragun-Damian and Dabert, 2012 by the length of setae ag3 190-230 (vs 145-160). The genetic distances (K2P) between COI haplotypes of S. plocei sp. nov. individuals (from P. cucullatus, P. nigerrimus and P. aurantius) and S. pseudonigritae ranges from 13.1-13.7%.
