Here, we describe a new genus of lice (Phthiraptera, Ischnocera) in the Oxylipeurus-complex, parasitising galliform hosts in the genera Tragopan Cuvier, 1829. This genus, Pelecolipeurusgen. nov., is separated from other members of the complex by the unique shape of the male subgenital plate and stylus, the male genitalia and other characters. The only previously-known species in the genus is Lipeurus longus Piaget, 1880, which is here tentatively re-described as Pelecolipeurus longus (Piaget, 1880), based on specimens from a non-type host, Tragopan temminckii (Gray, 1831). In addition, we describe a new species, Pelecolipeurus fujianensissp. nov., based on specimens from Tragopan caboti (Gould, 1857). An overview of the distribution patterns of ischnoceran lice on galliforms is presented, which suggests that host phylogeny, host biogeography and host biotope, as well as elevation of host range, may all be important factors that have structured louse communities on landfowl. We transfer the genus Afrilipeurus from the Oxylipeurus-complex to the Lipeurus-complex and include an emended key to the Oxylipeurus-complex.

Chewing lice are hosts to endosymbiotic bacteria as well as themselves being permanent parasites. This offers a unique opportunity to examine the cophylogenetic relationships between three ecologically interconnected organismal groups: birds, chewing lice, and bacteria. Here, we examine the cophylogenetic relationships between lice in the genus Guimaraesiella Eichler, 1949, their endosymbiotic Sodalis-allied bacteria, and a range of bird species from across South China. Both event and distance-based cophylogenetic analyses were explored to compare phylogenies of the three organismal groups. Pair-wise comparisons between lice-endosymbionts and bird-endosymbionts indicated that their evolutionary histories are not independent. However, comparisons between lice and birds, showed mixed results; the distance-based method of ParaFit indicated that their evolutionary histories are not independent, while the event-based method of Jane indicated that their phylogenies were no more congruent than expected by chance. Notably, louse host-switching does not seem to have affected bacterial strains, as conspecific lice sampled from distantly related hosts share bacteria belonging to the same clade.

IntroductionAvian head lice comprise a diverse group of distantly related genera of lice that exhibit a strongly convergent morphology. Due to their lack of free-living stages, their strong morphological adaptations to living on the host\’s head, and the limited opportunities for transfer between hosts during mating or nesting, the lateral transmission of head lice between non-conspecific hosts may be presumed to be restricted. Despite this, many species of head lice are ostensibly host generalists. We here examine lice of the head louse genus Philopteroides Mey, 2004, from bulbuls (Passeriformes: Pycnonotidae).

MethodsWe use two different methods, ParaFit and Jane, to get insights on the co-evolutionary history of Philopteroides species and their bulbul hosts. Jane was run with a variation of event costs.

ResultsOur phylogenetic analysis indicate that several morphologically cryptic species can be found in this group, most of which appear to be host specific. However, co-phylogenetic analyses indicate that host-switching has been common in the history of these lice, and co-speciation events have been rarer than expected. Moreover, lowest-cost co-evolutionary reconstructions under a variety of event costs are indistinguishable from random. An expanded dataset with more Philopterus-complex lice was found to be evenly balanced between host-switching and co-speciation events.

DiscussionThe transfer of avian head lice between host species is poorly understood, but evidently fairly common. Several potential routes are discussed, but direct evidence is missing. Potentially, the presence of multiple bulbul species at fruiting trees may be an important factor in this transfer. However, such transfer routes also do not explain why Philopteroides lice on bulbuls appear to be distinct from those of other hosts. Moreover, as many of the species recovered in our analysis are morphologically indistinguishable, cryptic speciation appears to be common in this group.

Patterns of prevalence in chewing lice (Phthiraptera) on wild birds are poorly known, as are the underlying factors that influence these patterns. Here, we analyze a data set consisting of published prevalence data of lice on shorebirds, as well as new prevalence data from shorebirds examined in Australia, Canada, China, Japan, and Sweden between 2007 and 2020. In total, prevalence data from 10 genera of lice from over 110 host species were included, including all major families of shorebirds. Using a generalized linear mixed model, we examine how the prevalence of lice of different genera varies between different sets of birds, focusing on two factors associated with migration (migration length and migration route). We found that host body size does not influence prevalence of lice in the Charadriiformes for any of the four most common and widely distributed louse genera (Actornithophilus, Austromenopon, Quadraceps, and Saemundssonia). Moreover, neither of the two migration variables showed any statistically significant correlations with prevalence, except for the genus Saemundssonia in which the prevalence of lice on short-distance migrants was significantly higher than on intermediate- and long-distance migrants. We also present 15 new records of chewing lice for China and 12 for Australia.

Babblers (Passeriformes: Leiothrichidae, Pellorneidae, Timaliidae) are parasitized by more genera of lice of the Brueelia complex than any other group of songbirds. However, the relationships of these louse groups are poorly known. We here try to resolve the relationships between Guimaraesiella (Guimaraesiella), Guimaraesiella (Cicchinella), and their putative sister group Priceiella by using mitochondrial cytochrome c subunit 1 (COI), 12S, and 16S sequences. Our data indicate that G. (Cicchinella) forms a monophyletic group of lice from babblers, but the relationship between G. (Guimaraesiella), G. (Cicchinella), and Priceiella could not be resolved. Moreover, the position of the third lineage of babbler-specific lice, containing only the aberrant species Guimaraesiella montisodalis, is unresolved. Morphologically, this species is different from all other Guimaraesiella in several characters and may represent a distinct lineage. We present some data indicating that (1) the Nanling Mountain range may be a biogeographical barrier to chewing lice and (2) host participation in mixed-species feeding flocks may influence host associations in Brueelia-complex chewing lice.

Seven new species of chewing lice in the genus Priceiella Gustafsson 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) coleyae Gustafsson et al., 2018, and Priceiella (Thescelovora) austini Gustafsson et al., 2018, and correct the type host subspecies for the latter. Finally, we amend the subgenus descriptions of Camurnirmus Gustafsson and Bush, 2017, and Thescelovora Gustafsson and Bush, 2017. As a result of these changes, Priceiella najeri Gustafsson et al., 2018, is moved to subgenus Thescelovora. An updated checklist of the genus Priceiella is provided.

The crested ibis has survived a dramatic population decline during the twentieth century, declining from a range across much of China, Japan, the Korean peninsula and nearby Russia, to a known world population of seven individuals. These formed the basis of a successful breeding program in Shaanxi, China. We examined ibises in this breeding program for ectoparasites, to establish whether any of the three chewing louse species known from this host had survived this severe host population bottleneck. We recovered representatives of three species of lice, identified as the same species as those previously known from the wild populations: Ardeicola nippon, Colpocephalum nipponi, and Ibidoecus meinertzhageni. Of these, the two first species were recovered from almost all examined hosts, whereas I. meinertzhageni was more rare. As these lice are host specific, this implies that all three louse species remarkably survived this bottleneck, and are now thriving in both the reintroduced and captive populations of crested ibis. This constitutes an unintentional success story in the conservation of parasitic species. We provide the first photos of all three species, as well as a preliminary assessment of their conservation status, and discuss the future of chewing louse conservation.
