Ten new species of Brueelia Kéler, 1936 (Phthiraptera: Ischnocera: Philopteridae) from nuthatches (Aves: Passeriformes: Sittidae), tits and chickadees (Paridae), and goldcrests (Regulidae)

Abstract

Abstract Ten new species of chewing lice in the genus Brueelia Kéler, 1936, are described from hosts in the families Paridae, Regulidae, and Sittidae. They are: Brueelia johnsoni n. sp. from Poecile sclateri eidos (Peters, 1927); Brueelia juniperi n. sp. from Baeolophus ridgwayi ridgwayi (Richmond, 1902); Brueelia kabulica n. sp. from Sitta tephronota tephronota Sharpe, 1872; Brueelia mpumalangensis n. sp. from Melaniparus niger niger (Vieillot, 1818); Brueelia nazae n. sp. from Parus cinereus caschmirensis Hartert, 1905; Brueelia oxyrhyncha n. sp. from Sitta nagaensis nagaensis Godwin-Austen, 1874; Brueelia picea. sp. from Parus major excelsus Buvry, 1857; Brueelia ragusica n. sp. from Sitta neumayer neumayer Michahelles, 1830; Brueelia regulicida n. sp. from Regulus calendula grinnelli Palmer, 1897; Brueelia sittacola n. sp. from Sitta carolinensis carolinensis Latham, 1790. Brueelia regulicida is the first Brueelia-complex louse to be described from the host family Regulidae. Collectively, the Brueelia of parid, regulid, and sittid hosts show two peculiar patterns. Firstly, lice on closely related hosts appear to be distantly related. Secondly, lice on most hosts in these families appear to be more closely related to lice on other host families than to each other. This contradicts the traditional view that Brueelia-complex lice on closely related hosts are themselves closely related. Potentially, the tendency of the hosts to participate in mixed-species feeding flocks may explain some of these patterns.
