Abstract
A new subgenus and three new species of parasitic lice (Phthiraptera: Ischnocera) in the Oxylipeurus-complex are described and illustrated. Forcipurellus new subgenus is part of the genus Reticulipeurus Kéler, 1958, and only includes species parasitic on partridges of the genus Arborophila Hodgson, 1837. The new species are: Reticulipeurus (Forcipurellus) diki new species ex Arborophila rubrirostris (Salvadori, 1879); Reticulipeurus (Forcipurellus) bracatus new species ex Arborophila atrogularis (Blyth, 1849); Reticulipeurus (Forcipurellus) longistylus new species ex Arborophila rufogularis guttata Delacour & Jabouille, 1928 and two other host subspecies. In addition, we redescribe the species Reticulipeurus (Forcipurellus) formosanus (Uchida, 1917) ex Arborophila crudigularis (Swinhoe, 1864) and Reticulipeurus (Forcipurellus) nitzschi Kéler, 1958 ex Arborophila torqueola torqueola (Valenciennes, 1825) and Arborophila torqueola millardi (Baker, 1921). Also, we briefly discuss four additional species that could not be described based on the specimens examined. A key to identify all species in the subgenus Forcipurellus is provided, as well as an emendation to include Forcipurellus in a previously published key to the Oxylipeurus-complex.

Mol Phylogenet Evol 2022; 174:107556. [PMID: 35738542 DOI: 10.1016/j.ympev.2022.107556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 04/19/2022] [Accepted: 05/27/2022] [Indexed: 11/30/2022]
Abstract
The avian feather louse Philopterus-complex (Phthiraptera: Ischnocera: Philopteridae) currently contains 12 genera that have been grouped together because of shared morphological characteristics. Although previously lumped into a single genus (Philopterus), more recent morphological treatments have separated the group into several different genera. Here we evaluate the status of these genera using DNA sequence data from 118 ingroup specimens belonging to ten genera in the Philopterus-complex: Australophilopterus Mey, 2004, Cinclosomicola Mey 2004, Clayiella Eichler, 1940, Corcorides Mey, 2004, Mayriphilopterus Mey, 2004, Paraphilopterus Mey 2004, Philopteroides Mey 2004, Philopterus Nitzsch, 1818, Tyranniphilopterus Mey, 2004, and Vinceopterus Gustafsson, Lei, Chu, Zou, and Bush, 2019. Our sampling includes 97 new louse-host association records. Our analyses suggest that the genus Debeauxoecus Conci, 1941, parasitic on pittas (Aves: Pittidae), is outside of the Philopterus-complex, and that there is strong support for the monophyly of a group containing the remaining genera from the complex. Some diverse genera, such as Philopterus (sensu stricto) and Mayriphilopterus are supported as monophyletic, whereas the genera Australophilopterus, Philopteroides, and Tyranniphilopterus are not. The present study is the largest phylogenetic reconstruction of avian lice belonging to the Philopterus-complex to date and suggests that further generic revision is needed in the group to integrate molecular and morphological information.

Combining Nuclear and Mitochondrial Loci Provides Phylogenetic Information in the Philopterus Complex of Lice (Psocodea: Ischnocera: Philopteridae). JOURNAL OF MEDICAL ENTOMOLOGY 2021; 58:252-260. [PMID: 32829404 DOI: 10.1093/jme/tjaa166] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Indexed: 06/11/2023]
Abstract
The Philopterus Complex includes several lineages of lice that occur on birds. The complex includes the genera Philopterus (Nitzsch, 1818; Psocodea: Philopteridae), Philopteroides (Mey, 2004; Psocodea: Philopteridae), and many other lineages that have sometimes been regarded as separate genera. Only a few studies have investigated the phylogeny of this complex, all of which are based on morphological data. Here we evaluate the utility of nuclear and mitochondrial loci for recovering the phylogeny within this group. We obtained phylogenetic trees from 39 samples of the Philopterus Complex (Psocodea: Philopteridae), using sequences of two nuclear (hyp and TMEDE6) and one mitochondrial (COI) marker. We evaluated trees derived from these genes individually as well as from concatenated sequences. All trees show 20 clearly demarcated taxa (i.e., putative species) divided into five well-supported clades. Percent sequence divergence between putative species (~5-30%) for the COI gene tended to be much higher than those for the nuclear genes (~1-15%), as expected. In cases where species are described, the lineages identified based on molecular divergence correspond to morphologically defined species. In some cases, species that are host generalists exhibit additional underlying genetic variation and such cases need to be explored by further future taxonomic revisions of the Philopterus Complex.
