Quill mites of the family Syringophilidae (Acariformes: Prostigmata) parasitising doves of the genus Turtur (Columbiformes: Columbidae)

Abstract

Mites belonging to the Syringophilidae family are a cosmopolitan and taxonomically diverse group of obligate and permanent parasites. These mites inhabit and reproduce within the hollow quills (calamus) of the wing, tail, and contour feathers. This study presents the first field observations of quill mites parasitising doves of the Turtur genus distributed in sub-Saharan Africa. A total of 145 host individuals from all five Turtur species (i.e., T. abyssinicus, T. afer, T. brehmeri, T. chalcospilos, and T. tympanistria) were examined during ornithological surveys conducted in Ghana, Uganda, Mozambique, and Nigeria. All examined bird species were found to be parasitised by a single oligoxenous syringophilid species, Meitingsunes tympanistria Skoracki & Dabert. Previously, this mite species had only been recorded from T. chalcospilos and T. tympanistria and from Tanzania and Togo; thus, the remaining dove species and countries of origin represent new host and locality records for this quill mite species. In our study, 20 individuals (13.8%) of the Turtur genus were infested by quill mites, with prevalence ranging from 8.8% to 24.2%. Mites were found to inhabit only the quills of wing coverts. No relationship was observed between the host body condition of two analysed host species (T. tympanistria and T. chalcospilos) and infestation by M. tympanistria. The fact that M. tympanistria exploits all representatives of the genus Turtur suggests that this mite species invaded these birds before their radiation, dating back approximately 15 Mya (Middle Miocene).
