Co-phylogeny of a hyper-symbiotic system: Endosymbiotic bacteria (Gammaproteobacteria), chewing lice (Insecta: Phthiraptera) and birds (Passeriformes).

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.

Species of Reticulipeurus Kéler, 1958 (Phthiraptera, Ischnocera, Oxylipeurus-complex) parasitic on species of Arborophila, with description of a new subgenus and three new species.

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.

Review of the chewing louse fauna of the invasive common myna (Acridotheres tristis), with new records from Palestine and a redescription of Brueelia chayanh Ansari, 1955 (Phthiraptera, Ischnocera, Brueelia-complex).

Palestine hosts a large diversity of birds, with 393 recorded species, but little data are available on the chewing lice fauna found on these birds. In this study, we surveyed the species of chewing lice found on the common myna, Acridotheres tristis, which is one of the most invasive bird species in the world. Forty-five mynas were examined to collect their ectoparasites, which were preserved and slide mounted. Among the 1004 chewing lice processed, we identified two species: Menacanthus eurysternus (Burmeister, 1838) (prevalence 100%) and Brueelia chayanh Ansari, 1955 (prevalence 82.2%). No other species of chewing louse known from A. tristis in its native range was found, showing a possible sorting event in the founding population of common myna in the region. Prevalence (100%) and abundance (22.3) were high compared to similar studies of the common myna. To contribute to future research on the lice of common mynas, we provide an annotated checklist of the louse species reported from this host globally. Also, we redescribe and illustrate Brueelia chayanh, and place Sturnidoecus tristisae Bughio et al., 2018 as a new junior synonym of Sturnidoecus bannoo Ansari, 1968.

Chewing lice of the Brueelia-complex (Phthiraptera: Ischnocera) parasitic on members of the Campephagidae (Aves: Passeriformes), with description of a new subgenus and 14 new species.

Fourteen new species of chewing lice in the Brueelia-complex are described, from hosts in the Campephagidae. In addition, Malardifax a new subgenus of Guimaraesiella Eichler, 1949 is described for the species occurring on minivets (Campephagidae: Pericrocotus). The new species and their hosts are: Guimaraesiella (Guimaraesiella) nouankaoensis n. sp. from Coracina caledonica seiuncta Mayr Ripley, 1941 and C. caledonica thilenii (Neumann, 1915); Guimaraesiella (Guimaraesiella) sphagmotica n. sp. from Coracina caeruleogrisea strenua (Schlegel, 1871) and C. caeruleogrisea adamsoni Mayr Rand, 1936; Indoceoplanetes (Capnodella) kamphaengphetensis n. sp. from Lalage melaschistos avensis (Blyth, 1852); Indoceoplanetes (Capnodella) saucia n. sp. from Edolisoma montanum montanum (Meyer, 1874); Indoceoplanetes (Capnodella) subarcens n. sp. from Edolisoma melas melas (Lesson, 1828); Indoceoplanetes (Indoceoplanetes) cinitemnina n. sp. from Edolisoma melas melas (Lesson, 1828); Indoceoplanetes (Indoceoplanetes) ephippiformis n. sp. from Edolisoma montanum montanum (Meyer, 1874); Indoceoplanetes (Indoceoplanetes) fodincana n. sp. from Coracina papuensis oriomo Mayr Rand, 1936, C. papuensis angustifrons (Salvadori, 1876), and C. papuensis elegans (Ramsay, 1881); Indoceoplanetes (Indoceoplanetes) incisoma n. sp. from Coracina macei siamensis (Baker, 1918) and C. macei rexpineti (Swinhoe, 1863); Indoceoplanetes (Indoceoplanetes) microgenitalis n. sp. from Coracina caeruleogrisea strenua (Schlegel, 1871); Indoceoplanetes (Indoceoplanetes) pterophora n. sp. from Coracina macei nipalensis (Hodgson, 1836); Indoceoplanetes (Indoceoplanetes) saburrata n. sp. from Coracina lineata ombriosa (Rothschild Hartert, 1905); Indoceoplanetes (Indoceoplanetes) wandoensis n. sp. from Coracina novaehollandiae melanops (Latham, 1802); and Indoceoplanetes (Indoceoplanetes) zambica n. sp. from Coracina pectoralis (Jardine Selby, 1828). Checklists and keys to the louse species of the Brueelia-complex parasitic on campephagid hosts are provided.

Descriptions of six new species of slender-bodied chewing lice of the Resartor-group (Phthiraptera: Ischnocera: Brueelia-complex).

Six new species of chewing lice in the Resartor-group (Brueelia-complex) are described and illustrated. They are: Aratricerca cerata n. sp. ex Zosterops capensis Sundevall, 1850; Aratricerca macki n. sp. ex Melidectes princeps Mayr Gilliard, 1951 and Ptiloprora perstriata perstriata (de Vis, 1898); Aratricerca madagascariensis n. sp. ex Randia pseudozosterops Delacour Berlioz, 1931; Turdinirmoides janigai n. sp. ex Prunella collaris nipalensis (Blyth, 1843) and P. collaris fennelli Deignan, 1964; Turdinirmoides rozsai n. sp. ex Carpodacus subhimachala (Hodgson, 1836); and Timalinirmus curvus n. sp. ex Yuhina castaniceps plumbeiceps (Godwin-Austen, 1877). A key to the species of Aratricerca, Turdinirmoides and Timalinirmus is provided.

One new genus and three new species of the Penenirmus-complex (Phthiraptera: Ischnocera) from China, with resurrection of Picophilopterus Ansari, 1947.

Three new species of chewing lice of the Penenirmus-complex (Phthiraptera: Ischnocera) are described and illustrated from woodpeckers (Picidae) and barbets (Megalaimidae) occurring in China. They are: Picophilopterus blythipici new species from Blythipicus pyrrhotis sinensis (Rickett, 1897), Laimoloima ruiliensis new genus, new species from Psilopogon asiaticus asiaticus (Latham, 1790), and Laimoloima tandani new genus, new species from Psilopogon virens virens (Boddaert, 1783). In addition, we provide illustrations of Picophilopterus pici sensu lato ex Picus canus sordidior (Rippon, 1906), and we present evidence that justifies resurrecting the genus Picophilopterus Ansari, 1947 to include the species infesting woodpeckers and Neotropical barbets (Capitonidae). Also, we erect the new genus Laimoloima to include the species from Asian barbets (Megalaimidae). The taxonomic position of Penenirmus species from African barbets (Lybiidae) and honeyguides (Indicatoridae) is unresolved. An updated checklist of the species in the Penenirmus-complex parasitic on non-passeriform hosts is provided, including species of the genus Turnicola Clay Meinertzhagen, 1938.

PHYLOGENETIC RELATIONSHIPS OF GUIMARAESIELLA AND PRICEIELLA (PHTHIRAPTERA: ISCHNOCERA) FROM BABBLERS AND NON-BABBLERS (PASSERIFORMES).

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.

Four new species of Guimaraesiella (Phthiraptera: Ischnocera: Brueelia-complex) from China.

Four new species of Guimaraesiella Eichler, 1949 are described and illustrated based on specimens collected in South China. They are: Guimaraesiella (Cicchinella) citreisoma new species ex Leiothrix lutea kwangtungensis Whistler, 1943 (Leiothrichidae); Guimaraesiella (Cicchinella) corrugata new species ex Alcippe hueti hueti David, 1874 (Leiothrichidae); Guimaraesiella (Cicchinella) petilorica new species ex Alcippe nipalensis nipalensis (Hodgson, 1837) (Leiothrichidae); and Guimaraesiella (Cicchinella) yuhinae new species from Yuhina flavicollis rouxi (Oustalet, 1896) (Zosteropidae); this is the first species of the Brueelia-complex recorded from a member of the Zosteropidae.

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.

New species of ischnoceran chewing lice (Phthiraptera: Philopteridae) from Chinese birds.

Five new species of chewing lice (Phthiraptera: Ischnocera) are described and illustrated from Chinese birds, as follows: Cuculicola calyptocamptus new species ex Hierococcyx sparverioides (Vigors, 1832) (Cuculiformes), Goniocotes kristinae new species ex Lophura swinhoii (Gould, 1863) (Galliformes), Goniocotes rolandi new species ex Crossoptilon harmani Elwes, 1881 (Galliformes), Rallicola (Rallicola) tibetana new species ex Zapornia bicolor Walden, 1872 (Gruiformes), and Resartor elugeus new species ex Alcippe fratercula yunnanensis Harington, 1913 (Passeriformes).

A MISIDENTIFICATION CRISIS PLAGUES SPECIMEN-BASED RESEARCH: A CASE FOR GUIDELINES WITH A RECENT EXAMPLE (ALI ET AL., 2020).

A recent paper in this journal concerning parasites of rock pigeons (Columba livia) published by Ali and colleagues exemplifies a growing trend of misidentified parasites in the literature, despite increased online resources that should help facilitate accurate identification. In the Ali et al. paper, a pigeon louse in the genus Columbicola (Phthiraptera: Ischnocera) is misidentified as Menopon gallinae, which is a parasite of chickens (Gallus gallus) and their relatives; moreover, this louse is from an entirely different suborder of lice (Phthiraptera: Amblycera). Another louse is misidentified as Goniodes dissimilis, another parasite of chickens and junglefowl. In addition, photographs of cestodes from pigeons in the same paper are not sufficient to confirm identification. Misidentifications are fueled, in part, by increasing pressure to publish coupled with a decrease in taxonomic expertise. We consider the downstream consequences of misidentification and suggest guidelines for authors, reviewers, and editors that could help to improve the reliability of specimen-based research.

Analysis of phoretic relation between chewing lice and hippoboscid flies of Columba livia.

Phoresy is a biologically mechanical phenomena where an immobile organism hitches on a other mobile organism to translocate. This behaviour is not studied very well on the field level especially between two important parasites infesting the same host. Parasite/parasite interaction is rarely studied through most biological host-parasite systems. Here, we evaluated the phoretic relation between parasitic chewing lice and hippoboscid flies (Pseudolynchia canariensis) on rock pigeons. A total of 69 captivated rock pigeons, Columba livia, were examined for the parasitic chewing lice and hippoboscid flies in Giza Zoo and two local farms near Cairo, Egypt. Results indicated that there is a positive correlation between infestation of hippoboscid flies and chewing lice. Also, the analysis of louse/louse interaction using ANOVA indicated a significant difference between the three chewing louse species which were recorded on the rock pigeons with relatively high abundance of two species, Columbicola columbae and Campanulotes compar. The analysis of hippoboscid flies' abundance and its relation with chewing lice infestation indicate a significant increase of lice intensity in case of high infestation with the fly. The level of hygiene of nest may be inversely related to level of parasite infestation. This work forms a step in the process of understanding parasite/parasite and host/parasite interactions using two parasitic species with a characteristic phoretic behaviour in nature.

Four new species of Myrsidea (Phthiraptera: Amblycera: Menoponidae) from Chinese babblers (Passeriformes: Leiothrichidae, Paradoxornithidae, Timaliidae).

Four new species of amblyceran chewing lice of the genus Myrsidea Waterston, 1915 are described from hosts of the babbler families Leiothrichidae, Paradoxornithidae and Timaliidae in China. They are: Myrsidea attenuata n. sp. from Garrulax maesi maesi (Oustalet, 1890), Myrsidea zhangae n. sp. from Ianthocincla berthemyi (Oustalet, 1876), Myrsidea liopari n. sp. from Lioparus chrysotis amoenus (Mayr, 1941) and L. chrysotis swinhoii (Verreaux, 1871), and Myrsidea suthorae n. sp. from Suthora verreauxi verreauxi Sharpe, 1883. A checklist of host-louse associations for identified and unidentified Myrsidea species known from babblers is provided.

Also, Guimaraesiella (Dicrurobates) sexmaculata (Piaget, 1880) and Guimaraesiella (Dicrurobates) dicruri (Ansari, 1955) are redescribed and illustrated. A key to identify adults of all 10 species included in the subgenus is provided.

Insect ectoparasites from wild passerine birds in the Azores Islands.

A total of 266 wild passerine birds (Passeriformes) representing eight species and nine subspecies from three islands of the Archipelago of the Azores were examined for ectoparasites. Two species of louse-flies Ornithomya avicularia and Ornithoica turdi (Diptera: Hippoboscidae), three species of fleas Ceratophyllus gallinae, Ceratophyllus sp. and Dasypsyllus gallinulae (Siphonaptera: Ceratophyllidae), and 11 species of chewing lice belonging to the genera Menacanthus, Myrsidea (Phthiraptera: Menoponidae), Ricinus (Phthiraptera: Ricinidae), Brueelia, Guimaraesiella, Philopterus, Sturnidoecus and Turdinirmus (Phthiraptera: Philopteridae) were recorded. At least one species of ectoparasite was found on 114 birds of six species. Guimaraesiella tovornikae and Myrsidea sylviae from Sylvia atricapilla are redescribed. Records of Ceratophyllus sp. and Sturnidoecus sp. from Turdus merula represent new parasite-host associations. Phoresy of Guimaraesiella amsel on Ornithoica turdi was also found. Parasitological parameters such as prevalence, intensity and abundance and geographic distribution of recorded ectoparasites are provided.

An annotated list of the species of lice (Insecta: Phthiraptera) described by Mohammad A.-R. Ansari.

Mohammad Atiq-ur-Rahman Ansari (1911-1979) was an Indian phthirapterist who contributed to the knowledge of parasitic lice (Insecta: Phthiraptera) from the Indian subcontinent with 41 papers published from 1944 to 1968. He described 195 new species and subspecies of chewing lice from birds and redescribed 182 previously known species of all groups of lice. Among the new species, 155 are still considered valid. We list all the species and subspecies described by Ansari under their original binomial or trinomial names, adding for each one: subsequent references by Ansari, current taxonomic status (i.e. taxa placed now in different genera, or with senior synonyms), type host, type locality, and deposition of type material when still extant. About 120 (62%) of Ansari's primary type specimens are deposited at museums in the United Kingdom and the U.S.A., with the remaining 75 primary types presumed lost. Four species are here considered species inquirenda, because the morphological data published by Ansari are not consistent with diagnostic characters of the genera in which he placed them, and their types could not be located to confirm their correct generic placement. They are Capraiella masumae Ansari, 1955; Craspedorrhynchus chicquera Ansari, 1955; Cuculicola jamilae Ansari, 1955 and Cuculoecus distinctus Ansari, 1955. We propose the name Philopterus ansarii nomen novum as a replacement for Philopterus kalkalichi Ansari, 1956e-preoccupied by Philopterus kalkalichi Ansari, 1955e-and designate a neotype for it. We also designate a neotype for Alcedoecus anularis Ansari, 1955e and Alcedoecus annulatus Tendeiro, 1965a, placing the latter name as an absolute junior synonym of the former.

Descriptions of three congeneric species of chewing lice of the Oxylipeurus-complex (Insecta: Phthiraptera: Philopteridae) from the turkey, Meleagris gallopavo, including a new genus and a new species.

The lice of the Oxylipeurus-complex parasitising the turkey, Meleagris gallopavo, belong to a previously undescribed genus. In this paper, we describe this genus as Valimia new genus, redescribe two of its species: Lipeurus polytrapezius Burmeister, 1838 and Oxylipeurus corpulentus Clay, 1938, and describe the new species Valimia necopinata, discovered during our examination of samples of the two known species. This occurrence represents the first record of three congeneric species of chewing lice parasitising the same host individual.

Review of Chinese species of the Oxylipeurus-complex (Phthiraptera: Philopteridae), with descriptions of two new genera and five new species.

Chewing lice of the Oxylipeurus-complex known from China are described and illustrated. The genera Megalipeurus Kéler, 1958 and Reticulipeurus Kéler, 1958 are considered valid, resurrected from synonymy and redescribed. Two new genera are described: Cataphractomimus new genus and Sinolipeurus new genus, which are proposed for species that do not fit into any previously described genus within the Oxylipeurus-complex. The following species are redescribed and illustrated: Reticulipeurus mesopelios (Nitzsch [in Giebel], 1866); Reticulipeurus robustus (Rudow, 1869); Reticulipeurus reevesi (Clay, 1938); Reticulipeurus baileyi (Clay, 1938); Reticulipeurus crossoptilon (Clay, 1938); Reticulipeurus ithaginis (Clay, 1938); Sinolipeurus tetraophasis (Clay, 1938) new combination. Several species previously placed in the genus Oxylipeurus are given new generic combinations. In addition, the following five new species are described and illustrated: Megalipeurus sinensis new species ex Arborophila gingica (Gmelin, 1789); Cataphractomimus mirapelta new species ex Lophophorus lhuysii Geoffroy Saint-Hilaire, 1866; Cataphractomimus impervius new species ex Lophophorus sclateri sclateri Jerdon, 1870; Cataphractomimus junae new species and Sinolipeurus sichuanensis new species ex Tragopan temminckii (J.E. Gray, 1831).
