Abstract
A new genus of chewing louse as Bobdalgleishia, and its type species Bobdalgleishia stephanophallus sp. n. (Phthiraptera) belonging to the Brueelia-complex (Ischnocera: Philopteridae) are described. Adults of the new species are fully described, illustrated and compared morphologically with the type species of Motmotnirmus Mey & Barker, 2014, which is its closest relative. The type host of Bobdalgleishia stephanophallus is a subspecies of the great jacamar Jacamerops aureus ridgwayi Todd, 1943, an endemic Amazonian bird distributed in northern Brazil, and the type locality is the State of Pará. Bobdalgleishia is a remarkable genus with unique morphological and chaetotaxic characters which readily separate it from other members of the Brueelia-complex, in particular by having the first two marginal temporal and ocular setae very long.
Highlights
The known chewing lice of the family Philopteridae (Ischnocera) parasitic on Galbuliformes (Aves) are six species of the genus Mayriphilopterus Mey, 2004 (Philopteruscomplex) (Mey 2004, Valim and Linardi 2007) and eight species of the genus Picicola Clay & Meinertzhagen, 1938 (Degeeriella-complex) (Oniki and Emerson 1981, Valim and Linardi 2006, Price and Weckstein 2006)
The type host of B. stephanophallus is a subspecies of the great jacamar Jacamerops aureus ridgwayi Todd, 1943, an endemic Amazonian bird distributed in northern Brazil, and the type locality is the State of Pará
The new genus is distinct from its sympatric relatives, as well as from all other genera included in the Brueelia-complex, both by morphological and chaetotaxic characters in both sexes
Summary
The known chewing lice of the family Philopteridae (Ischnocera) parasitic on Galbuliformes (Aves) are six species of the genus Mayriphilopterus Mey, 2004 (Philopteruscomplex) (Mey 2004, Valim and Linardi 2007) and eight species of the genus Picicola Clay & Meinertzhagen, 1938 (Degeeriella-complex) (Oniki and Emerson 1981, Valim and Linardi 2006, Price and Weckstein 2006). Among the genera belonging to the Brueelia-complex (Philopteridae sensu lato), some have a worldwide distribution, while others are geographically endemic and/or with host distribution restricted to certain host group (Mey and Barker 2014, Valim and Palma 2015). The new genus is distinct from its sympatric relatives, as well as from all other genera included in the Brueelia-complex, both by morphological and chaetotaxic characters in both sexes. This is the first record of a member of the Brueeliacomplex on Galbuliformes hosts
