A New Species of Sucking Louse from the Mandrill from Gabon with a Review of Host Associations and Geographical Distributions, and Identification Keys to Members of the Genus Pedicinus (Phthiraptera: Anoplura: Pedicinidae)
Journal of Parasitology, 2020Co-Authors: Lance A. Durden, Sharon E Kessler, Joanna M. Setchell, Larson Boundenga, Barthélémy Ngoubangoye, Thierry Audrey Tsoumbou, Cyr I. Moussadji-kinga, Michel Halbwax, Jennifer Nichols, Stephen E. GreimanAbstract:Members of the Sucking Louse genus Pedicinus are ectoparasites of cercopithecid primates in Africa, Asia, and Gibraltar. Pedicinus gabonensis n. sp. is described on the basis of adult male and female specimens collected from the mandrill (Mandrillus sphinx) in Gabon. The new species is compared morphologically with other members of the genus Pedicinus, and a nuclear elongation factor 1 alpha gene sequence is provided. Host associations and geographical distributions of the 18 previously recognized species of the genus and of P. gabonensis n. sp. are reviewed. Updated identification keys are provided for males and females of all known valid species of Pedicinus.

rapid host expansion of an introduced parasite the spiny rat Louse polyplax spinulosa psocodea phthiraptera polyplacidae among endemic rodents in australia
Parasites & Vectors, 2020Co-Authors: Wei Wang, Lance A. Durden, Renfu ShaoAbstract:Historical European exploration and colonization resulted in the introduction of four species of rodents to the Australian continent from Eurasia: the brown rat, Rattus norvegicus, the black rat, R. rattus, the Pacific rat, R. exulans, and the house mouse, Mus musculus. The spread of these rodents created opportunities for their co-introduced Sucking lice to parasitize and adapt to endemic rodents in Australia. We collected Sucking lice from rodent specimens in seven museums across Australia. We identified the spiny rat Louse, Polyplax spinulosa, based on morphology. We sequenced the mitochondrial cox1 and rrnL genes of P. spinulosa specimens and constructed a phylogenetic tree with rrnL sequences. We examined 989 rodent specimens of 54 species and collected 2111 adult Sucking lice and 1064 nymphal Sucking lice. We found that P. spinulosa had nearly doubled its host range by parasitizing at least six endemic rodent species in Australia. The other two introduced lice, P. serrata and Hoplopleura pacifica, however, have apparently failed to expand to any endemic rodents in Australia. Our analysis of mitochondrial rrnL gene sequences divided P. spinulosa into two genotypes (European vs Southeast Asian), which differ by 7.5%; both genotypes were introduced into Australia and then expanded their host ranges to include endemic rodents. The earliest record of a European ship landing in Australia was in 1606, followed by British settlement in 1788. The expansion of P. spinulosa to at least six endemic rodent species in Australia has therefore occurred in the time frame of 200 to 400 years, which is extremely rapid relative to its host expansion to eight native rat species in Eurasia in ~ 16 million years since it diverged from P. serrata. The host expansion of P. spinulosa is remarkable for a blood-Sucking Louse and is in stark contrast to the absence of host expansion by P. serrata and H. pacifica. Comparison among these three introduced Sucking lice indicated that both Louse-specific factors and host-specific factors can contribute to the success or failure of host expansion.

a new species of Sucking Louse from the long tailed ground squirrel urocitellus undulatus from mongolia with a key to species and a review of host associations and geographical distributions of members of the genus linognathoides psocodea anoplura polyplacidae
Journal of Parasitology, 2019Co-Authors: Lance A. Durden, Joseph A Cook, Chase Robinson, Bryan S Mclean, Batsaikhan Nyamsuren, Stephen E. GreimanAbstract:Members of the genus Linognathoides are ectoparasites of ground squirrels and marmots (Rodentia: Sciuridae) in the Nearctic, Palearctic, and Afrotropical regions. Linognathoides urocitelli n. sp. is described based on adult male and female and third-instar nymphal specimens collected from the long-tailed ground squirrel (Urocitellus undulatus) in Mongolia. The new species is compared morphologically to other members of the genus Linognathoides. Additionally, DNA sequences of a 610-base pair (bp) fragment of the nuclear 18S rDNA gene, a 452-bp fragment of the mitochondrial 12S rrnS gene, and a 363-bp fragment of the mitochondrial 16S rrnL gene are provided. Host associations and geographical distributions of the 11 previously recognized species of the genus, and of Linognathoides urocitelli n. sp., are reviewed. A dichotomous identification key to adults of all known species in the genus Linognathoides is provided.

Parasites & Vectors, 2018Co-Authors: Wei Wang, Lance A. Durden, Haylee J. Weaver, Fan Song, Renfu ShaoAbstract:The Sucking Louse fauna of endemic Australian rodents has been under-studied for decades. Sixty-five species of native rodents have been recorded in Australia. However, only 11 species of lice have been reported from 11 species of endemic Australian rodents. We describe a new species of Sucking Louse, Hoplopleura villosissima Wang (Psocodea: Phthiraptera: Hoplopleuridae), and report a new host record of the spiny rat Louse, Polyplax spinulosa Burmeister, 1839 (Psocodea: Phthiraptera: Polyplacidae), from the long-haired rat, Rattus villosissimus Waite (Rodentia: Muridae), which is endemic to Australia. This study is the first record of Sucking Louse from R. villosissimus and the first record of a species of Polyplax Enderlein, 1904 from an endemic Australian rodent. This study brings the total number of Sucking Louse species in endemic Australian rodents from 11 to 13. Previously, only the introduced brown rat, Rattus norvegicus Berkenhout and the black rat, Rattus rattus Linnaeus were recorded as the hosts of P. spinulosa in Australia. Because R. villosissimus overlaps with R. rattus in distribution but not with R. norvegicus, we propose that P. spinulosa transferred to R. villosissimus from R. rattus.

the single mitochondrial chromosome typical of animals has evolved into 18 minichromosomes in the human body Louse pediculus humanus
Genome Research, 2009Co-Authors: Renfu Shao, Ewen F Kirkness, Stephen C BarkerAbstract:The J. Craig Venter Institute, Rockville, Maryland 20850, USAThe mitochondrial (mt) genomes of animals typically consist of a single circular chromosome that is ;16-kb long and has37 genes. Our analyses of the sequence reads from the Human Body Louse Genome Project and the patterns of gelelectrophoresis and Southern hybridization revealed a novel type of mt genome in the Sucking Louse, Pediculus humanus.Instead of having all mt genes on a single chromosome, the 37 mt genes of this Louse are on 18 minicircular chromosomes.Each minicircular chromosome is 3–4 kb long and has one to three genes. Minicircular mt chromosomes are also presentin the four other species of Sucking lice that we investigated, but not in chewing lice nor in the Psocoptera, to whichSucking lice are most closely related. We also report unequivocal evidence for recombination between minicircular mtchromosomes in P. humanus and for sequence variation in mt genes generated by recombination. The advantages ofa fragmented mt genome, if any, are currently unknown. Fragmentation of mt genome, however, has coevolved withbloodfeedingintheSuckinglice.Itwillbeofinteresttoexplorewhetherornotlifehistoryfeaturesareassociatedwiththeevolution of fragmented chromosomes.[The nucleotide sequences of the minicircular mitochondrial chromosomes reported in this study have been submitted toGenBank (http://www.ncbi.nlm.nih.gov/Genbank/) under accession nos.

A new species of Sucking Louse (Phthiraptera: Anoplura) from Australia, and a key to the Australian species of Hoplopleura
Magnolia Press, 2008Co-Authors: Haylee J. Weaver, Philip S. BartonAbstract:A new species of Sucking Louse, Hoplopleura zyzomydis, is described and illustrated from the common Australian rock rat Zyzomys argurus (Thomas, 1889) (Rodentia: Muridae), collected in northwest Queensland, Australia. This is the first record of a Sucking Louse from the genus Zyzomys, and its morphology is contrasted with other Australian Hoplopleura species. Hoplopleura zyzomydis is unique in having a combination of short dorsal principal thoracic setae and setae absent from paratergal plates 4–6. A key to the Australian species of Hoplopleura is presented.

host associations of ectoparasites of the gray mouse lemur microcebus murinus in northwestern madagascar
Journal of Parasitology, 2020Co-Authors: Sharon E Kessler, Alida F Hasiniaina, Ute Radespiel, Alexandr A Stekolnikov, Kayleigh Chalkowski, Sarah ZohdyAbstract:Eight species of ectoparasites were collected during 225 gray mouse lemur, Microcebus murinus (J. F. Miller), captures, in Ankarafantsika National Park, Madagascar, in 2010-2011. The ixodid tick, Haemaphysalis lemuris Hoogstraal, was the most common ectoparasite and was mostly represented by nymphs. Other ectoparasites recorded include the polyplacid Sucking Louse, Lemurpediculus madagascariensis Durden, Kessler, Radespiel, Zimmermann, Hasiniaina, and Zohdy; the ixodid tick, Haemaphysalis simplex Neumann; an undescribed laelapid mite in the genus Aetholaelaps; another laelapid belonging to the genus Androlaelaps; the chigger mite Schoutedenichia microcebi Stekolnikov; an undescribed species of atopomelid mite in the genus Listrophoroides; and an undescribed species of psoroptid mite in the genus Cheirogalalges. Except for the 2 species of ticks and 1 species of chigger, these ectoparasites may be host-specific to M. murinus. Total tick (H. lemuris and H. simplex) infestation was significantly greater in August than October, whereas Louse (L. madagascariensis) infestation was significantly greater in October. There was no significant difference in tick infestations between male and female lemurs, but male lemurs had significantly more lice than female lemurs. Reproductive status was not a significant predictor of tick infestation in males and females.

a new species of Sucking Louse phthiraptera anoplura polyplacidae from the gray mouse lemur microcebus murinus primates cheirogaleidae in madagascar
Journal of Medical Entomology, 2018Co-Authors: Sharon E Kessler, Alida F Hasiniaina, Ute Radespiel, Elke Zimmermann, Sarah ZohdyAbstract:Lemurpediculus madagascariensis sp. nov. (Phthiraptera: Anoplura: Polyplacidae) is described from the Gray Mouse lemur, Microcebus murinus (J. F. Miller) (Primates: Cheirogaleidae), from Ankarafantsika National Park, Madagascar. Lemurs were trapped using Sherman Live Traps and visually inspected for lice, which were preserved in 90% ethanol. Adults of both sexes and the third-instar nymph of the new species are illustrated and distinguished from the four previously known species of Lemurpediculus: L. verruculosus (Ward); L. petterorum Paulian; L. claytoni Durden, Blanco, and Seabolt; and L. robbinsi Durden, Blanco, and Seabolt. It is not known if the new species of Louse is a vector of any pathogens or parasites.
