A new species of sucking louse Hoplopleura villosissima n. sp. (Psocodea: Phthiraptera: Hoplopleuridae) and 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) in Australia

“…More than 540 species of blood-sucking lice have been described that parasitise over 840 mammal species belonging to 12 mammalian orders [26,27]. Small rodents are the most common hosts of sucking lice: about 67% of the described sucking lice species are found on rodents [28]. The sucking lice are of medical and veterinary signi cance as vectors of louse-borne pathogens (viruses, bacteria, fungi and protozoa) to vertebrate hosts [29].…”

Background: Lice are blood-sucking insects that are of medical and veterinary signi cance as parasites and vectors for various infectious agents. More than half of described blood-sucking lice species are found on rodents. Rodents are important hosts of several Bartonella and Rickettsia species and some of these pathogens are characterised as human pathogens in Europe. Rodent ectoparasites, such as eas and ticks, are important vectors of Bartonella spp. and Rickettsia spp., but knowledge about the presence of these bacteria in lice is limited. The aim of this study was to determine the prevalence of Bartonella and Rickettsia bacteria in lice collected from rodents in Slovakia. Methods: The ectoparasites were collected from small rodents captured from 2010 to 2015 at four different sites in eastern Slovakia. The presence of Bartonella and Rickettsia pathogens in lice samples was screened by real-time PCR, targeting ssrA and gltA genes respectively. The molecular characterisation of the Bartonella strains was based on sequence analysis of partial rpoB and ITS genes, and of the Rickettsia species on sequence analysis of the gltA gene. Results: A total of 1074 lice of seven species were collected from six rodent species in Slovakia from 2010 to 2015. Bartonella DNA was detected in three species of lice Hoplopleura a nis (collected from Apodemus agrarius, A. avicollis and Myodes glareolus), Polyplax serrata (from A. agrarius) and Hoplopleura sp. (from A. avicollis). Sequence analysis revealed that the Bartonella strains belonged to the B. coopersplainsensis, B. tribocorum and B. taylorii genogroups. Rickettsia DNR was detected in H. a nis and P. serrata lice collected from A. agrarius. Sequence analysis revealed the presence of two Rickettsia species: R. helvetica and Rickettsia sp. Conclusions: To the best of the authors' knowledge, this is the rst report on the occurrence and diversity of Bartonella spp. and Rickettsia spp. in lice collected from small rodents in Europe. This study is also the rst to detect B. coopersplainsensis in Slovakia.

Aim of this work is to substantiate the hypothesis that the absence of lice in bats is associated with the electrification of the surface of their body during the flight.Discussion. The paper analyzes the physical phenomenon of friction electrification, the triboelectric series of substances with special attention to the objects of atmospheric electricity, and the Cohen rule that relates the dielectric properties of a substance to its permittivity. The electrical properties of the atmosphere are described including the occurrence of a potential difference between the Earth's surface and the ionosphere and the mechanism of maintaining this potential as a result of charging the ground with negative electricity by thunderstorms. The results of experimental data on the formation of a positive electrostatic charge on the surface covers of insects and birds are presented. It is hypothesized that the hair and skin membranes of bats should also be positively electrified during flight. The reasons that prevent lice from living in electrified bat hair are described. It is proposed to explain the presence of developed sebaceous glands in bats as a way of discharging electrostatic charge before returning to the shelter and the bell structure of the hair cuticle as a device for retaining the secretion of sweat glands.Conclusion. The absence of lice in bats is a direct consequence of their adaptation to active flight.

Based on a comprehensive study of museum specimens, eight new species of sucking lice of the genus Hoplopleura Enderlein, 1904 (Psocodea: Phthiraptera: Hoplopleuridae), are described from six genera of Australian Old Endemic rodents: Conilurus Ogilby, 1838 (Rodentia: Muridae), Leggadina Thomas, 1910 (Rodentia: Muridae), Leporillus Thomas, 1906 (Rodentia: Muridae), Mesembriomys Palmer, 1906 (Rodentia: Muridae), Pogonomys Milne-Edwards, 1877 (Rodentia: Muridae), and Xeromys Thomas, 1889 (Rodentia: Muridae). The description of these new species increases the number of sucking louse species from endemic Australian rodents from 13 to 21 and extends the records of sucking lice to all of the 14 genera of endemic rodents in Australia. Our results show that sucking lice are much more diverse among rodents in Australia than previously known. Furthermore, the Australian Hoplopleura species are host specific—each Hoplopleura species, including the eight new species described in the present study, parasitizes only a single host species, except Hoplopleura irritans Kuhn and Ludwig, 1967 (Psocodea: Phthiraptera: Hoplopleuridae) and Hoplopleura melomydis Weaver, 2017 (Psocodea: Phthiraptera: Hoplopleuridae), each of which is found on two host species. An updated dichotomous key for identifying Australian Hoplopleura species is included.
