Two new feather mite species of the genus Montesauria Oudemans (Analgoidea: Proctophyllodidae) from thrushes (Passeriformes: Turdidae) in the Indian Subcontinent

Abstract

Two new feather mite species of the genus Montesauria Oudemans, 1905, collected from thrushes (Turdidae) in India, are described: Montesauria hernandesi sp. n. from Turdus dissimilis Blyth, 1847 and M. caerulea sp. n. from Myophonus caeruleus (Scopoli, 1786). Both species belong to the merulae species group, being morphologically closest to other two species of the genus, previously described from birds of the family Turdidae in Asia (Japan): M. sibirica Kuroki, Nagahori and Mironov, 2006 and M. aurea Kuroki, Nagahori and Mironov, 2006, respectively. The new species most clearly differ from those described in Japan by the dorsal shield ornamentation. In both sexes of M. hernandesi sp. n., the ornamentation of the prodorsal and hysteronotal shields is represented by round and ovate lacunae, and the ornamentation of the lobar shield of females has few ovate lacunae. In both sexes of M. caerulea sp. n., the ornamentation of the hysteronotal shield is very particular, with large and almost round lacunae in the anterior half and small ovate lacunae in the posterior half.
