A new feather mite species of the genus Trouessartia Canestrini, 1899 (Acarina, Trouessartiidae) – an integrative description (morphology and DNA barcoding data)
A new species of the feather mite genusTrouessartia(Trouessartiidae) is described from the Large NiltavaNiltavagrandis(Blyth) (Passeriformes, Muscicapidae) in Northeast India (Meghalaya, Jaintia Hills, Shnongrim village).TrouessartianiltavaeConstantinescu,sp. n.is morphologically closely related (no phylogenetic meaning) toT.bulligeraGaud, 1968 fromClytorhynchushamlini(Mayr) (Passeriformes: Monarchidae), sharing in males a unique character within the genus, by having setaeeon legs IV hemispheroid, with spine-shaped apex. Males of the new species have the prodorsal shield without ornamentation, the prohysteronotal shield and lobar shield connected, and the terminal cleft parallel sided. Females have the posterior half of the hysteronotal shield ornamented with large ovate lacunae in central area and small elliptical lacunae marginally. To the morphological description of this new feather mite species we added sequence data on the mitochondrial cytochrome c oxidase subunit I gene fragment (COI). The phylogenetic relationships betweenTrouessartiaspecies are briefly discussed.
