NEW SPECIES AND NEW RECORDS OF PRICEIELLA (PHTHIRAPTERA: ISCHNOCERA: BRUEELIA-COMPLEX) FROM SOUTH CHINA.

Seven new species of chewing lice in the genus PriceiellaGustafsson and Bush, 2017, are described and illustrated based on specimens collected in south China. They are Priceiella (Camurnirmus) tanydrepanus n. sp. from Garrulax castanotis castanotis (Ogilvie-Grant, 1899); Priceiella (Camurnirmus) nanlingensis n. sp. from Garrulax maesi maesi (Oustalet, 1890); Priceiella (Thescelovora) brutifrons n. sp. from Turdinus brevicaudatus stevensi (Kinnear, 1925); Priceiella (Thescelovora) chuae n. sp. from Pellorneum albiventre cinnamomeus (Rippon, 1900); Priceiella (Thescelovora) catanachei n. sp. from Stachyris strialata swinhoei Rothschild, 1903; Priceiella (Thescelovora) dehongensis n. sp. from Stachyris nigriceps yunnanensis La Touche, 1921; and Priceiella (Thescelovora) rotundiceps n. sp. from Pomatorhinus ruficollis styani Seebohm, 1884. Several of these new species constitute the second species of Priceiella known from the host, suggesting that local endemism may be high in this louse genus. We also provide new host records for Priceiella (Thescelovora) coleyaeGustafsson et al., 2018, and Priceiella (Thescelovora) austiniGustafsson et al., 2018, and correct the type host subspecies for the latter. Finally, we amend the subgenus descriptions of CamurnirmusGustafsson and Bush, 2017, and ThescelovoraGustafsson and Bush, 2017. As a result of these changes, Priceiella najeriGustafsson et al., 2018, is moved to subgenus Thescelovora. An updated checklist of the genus Priceiella is provided.

The genera and species of the Brueelia-complex (Phthiraptera: Philopteridae) described by Mey (2017).

Two large taxonomic revisions of chewing lice belonging to the Brueelia-complex were published independently in 2017: Gustafsson Bush (August 2017) and Mey (September 2017). However, Mey (2017) was incorrectly dated "Dezember 2016" on the title page. These two publications described many of the same taxonomic units under different names and therefore, the names in Gustafsson and Bush (2017) have priority over the synonyms in Mey (2017). Here we clarify some of the resulting taxonomic confusion.                Firstly, we confirm the availability of the genera Guimaraesiella Eichler, 1949 and Acronirmus Eichler, 1953, as well as the status of Nitzschinirmus Mey Barker, 2014 as a junior synonym of Guimaraesiella.                Nine genera were described and simultaneously placed as juniors synonyms by Mey (2017: 182). We agree with his synonymy in seven of them: Australnirmus Mey, 2017 under Saepocephalum Gustafsson Bush, 2017; Couanirmus Mey, 2017 under Couala Gustafsson Bush, 2017; Estrildinirmus Mey, 2017 under Mirandofures Gustafsson Bush, 2017; Harpactiacus Mey, 2017 under Harpactrox Gustafsson Bush, 2017; Leiothrichinirmus Mey, 2017 under Resartor Gustafsson Bush, 2017; Manucodiacus Mey, 2017 under Manucodicola Gustafsson Bush, 2017, and Protonirmus Mey, 2017 under Ceratocista Gustafsson Bush, 2017. Furthermore, Mey (2017) described and placed Pomatostomiacus as an absolute junior synonym of Sychraella Gustafsson Bush, 2017; here, we argue that Pomatostomiacus is actually a junior synonym of Anarchonirmus Gustafsson Bush, 2017. Also, Mey (2017) described and placed Timalinirmus as a probable junior synonym of Turdinirmoides Gustafsson Bush, 2017; here we argue that Timalinirmus is a valid genus.We place ten more genera from Mey (2017) as junior synonyms, as follows: Callaenirmus Mey, 2017 and Philemoniellus Mey, 2017 under Guimaraesiella Eichler, 1949; Carpodaciella Mey, 2017 under Turdinirmoides Gustafsson Bush, 2017; Cinclosomatiellum Mey, 2017 under Maculinirmus Zlotorzycka, 1964; Koanirmus Mey, 2017 and Tesonirmus Mey, 2017 under Couala Gustafsson Bush, 2017; Garrulaxeus Mey, 2017 under Priceiella (Camurnirmus) Gustafsson Bush, 2017; Lycocoranirmus Mey, 2017 under Corvonirmus Eichler, 1944; Neosittiella Mey, 2017 and Plesionirmus Mey, 2017 under Brueelia Kéler, 1936.                We accept Melinirmus Mey, 2017 as valid, and Mohoaticus Mey, 2017 as a valid subgenus of Guimaraesiella Eichler, 1949. Also, we provisionally accept Ptilononirmus Mey, 2017 as valid but, until a proper redescription determines its true status, we categorize Ptilononirmus as genus inquirenda.                We accept most species described by Mey (2017) as valid, except for two which we place as junior synonyms: Callaenirmus kokakophilus Mey, 2017 under Brueelia callaeincola Valim Palma, 2015, and Mohoaticus pteroacariphagus Mey, 2017 under Guimaraesiella (Mohoaticus) diaprepes (Kellogg Chapman, 1902). We agree with Mey's assessment that four of his new species are junior synonyms of previously described taxa. Furthermore, among the species (subspecies) described by Mey (2017) as new, we establish 31 new generic (subgeneric) combinations, and we regard 16 species as species inquirenda, and three as incertae sedis.

Twelve new species of Priceiella (Phthiraptera: Ischnocera: Philopteridae) from Old World babblers, with keys to species of two subgenera and checklists of species for the genus.

Twelve new species of chewing lice in the genus Priceiella Gustafsson Bush, 2017, are described from Old World "babblers" (Leiothrichidae, Paradoxornithiidae, Pellorneidae and Timaliidae). Eight species belong to the subgenus Thescelovora Gustafsson Bush, 2017: Priceiella (Thescelovora) calcicola n. sp. from Turdinus crispifrons crispifrons; Priceiella (Thescelovora) fuscicaena n. sp. from Malacopteron magnum magnum and Malacopteron cinereum cinereum; Priceiella (Thescelovora) orichalca n. sp. from Turdinus brevicaudatus leucostictus and four other host species; Priceiella (Thescelovora) chanthaburiana n. sp. from Megapomatorhinus hypoleucos tickelli and Pomatorhinus schisticeps klossi; Priceiella (Thescelovora) macrocephala n. sp. from Megapomatorhinus hypoleucos wrayi; Priceiella (Thescelovora) coleyae n. sp. ex Stachyris striolata tonkinensis; Priceiella (Thescelovora) austini n. sp. ex Pomatorhinus ruficollis intermedius; and Priceiella (Thescelovora) ornata n. sp. ex Psittiparus gularis fokiensis. The remaining four species belong to the subgenus Camurnirmus Gustafsson Bush, 2017: Priceiella (Camurnirmus) najeri n. sp. from Garrulax monileger stuarti and three other hosts; Priceiella (Camurnirmus) bohsae n. sp. from Garrulax strepitans; Priceiella (Camurnirmus) lindquistae n. sp. ex Ianthocincla chinensis chinensis; Priceiella (Camurnirmus) sonorae n. sp. ex Garrulax maesi maesi. We redescribe and illustrate Priceiella (Camurnirmus) rhinocichlae (Eichler, 1957). Keys to species of two subgenera, a comprehensive checklist of all the species of Priceiella, and a host-louse list are provided.
