The study of the parasitofauna of the house mouse Mus musculus (Rodentia: Muridae) Linnaeus is particularly important owing to its multiple relationships with humans - as a cosmopolitan, synanthropic rodent, bred for pets, food for other animals or laboratory animal. This article proposes and describes a new genus and species of the parasitic mite based on adult and immature stages from the house mouse. Glossicodex musculi gen. n., sp. n. is a medium-sized demodecid mite (adult stages on average 199 µm in length) found in mouse tissue of the tongue. It is characterized by two large, hooked claws on each tarsus of the legs; the legs are relatively massive, consisting of large, non-overlapping segments. The palps consist of three slender, clearly separated, relatively narrow segments, wherein their coxal segments are also quite narrow and spaced. Also, segments of the palps of larva and nymphs are clearly isolated, and on the terminal segment, trident claws that resemble legs' claws can be found. On the ventral side, in immature stages, triangular scuta, topped with sclerotized spur, can be also observed. Glossicodex musculi was noted in 10.8% of mice with a mean infection intensity of 2.2 parasites per host.

“…Mites of the family Demodecidae (Acari: Prostigmata) are skin parasites observed in mammals belonging to most orders. Among the over 120 species described so far, nearly 40% are species specific to various rodents (Izdebska et al 2014, Izdebska & Rolbiecki 2015a and have been described from hosts of the most numerous suborder, Myomorpha, as well as in Sciuromorpha and Hystricomorpha. However, to date, no information has been available concerning the occurrence of Demodecidae in rodents of the suborder Castorimorpha, including Heteromyidae, Geomyidae, and Castoridae.…”

A new species of demodecid mite, Demodex castoris sp. nov. (Acari: Prostigmata: Demodecidae), is described based on adult stages from the skin of the nasal region of the Eurasian beaver Castor fiber Linnaeus, 1758, collected in Poland. This is the first detection of a representative demodecid mite in rodents of the suborder Castorimorpha and also represents the first detection of a skin mite in Eurasian beavers. The new species is a small skin mite (average 173 µm in length) characterized by sexual dimorphism related to body proportions. D. castoris sp. nov. was observed in 4 out of 6 beavers examined (66.6%), with a mean intensity of 10.8 and an intensity range of 2-23 ind. host(-1). This paper also contains a checklist of parasitic arthropods known from Castor spp.

“…as D. apodemi; specimens from A. agrarius, probably belongs to the separate species Apodemus sylvaticus (Linnaeus, 1758) (Linnaeus, 1758) Great Britain loc. class[15,57], Poland[58], Russia[56] …”

Demodecidae are the most specialized parasitic mites of mammals; they typically inhabit the skin, but they have been found in other tissues and organs. They can cause demodecosis (a disease which is hazardous and difficult to cure) in humans, domestic animals and livestock. They are parasites with high host and topical specificity. They have been found for most orders of mammals, and they are common in the populations of numerous host species. Therefore, they not only constitute an important subject of veterinary and medical study, but also comprise an excellent model for faunistic and parasitological analyses concerning different aspects of functioning and evolution of the host–parasite relationship. The current level or knowledge of demodecid mites is irregular and fragmentary, and numerous questions require elaboration and ordering, from the taxonomic diversity to geographic distribution and relations with hosts. Such data may be of use i.a. for the development of more efficient and reliable diagnostic methods, as well as understanding the etiology and pathogenesis mechanisms of demodecosis, currently a contentious issue. The present paper lists all formally-described valid species of demodecid mites, together with other functioning specific names, verified and with comments on their status. This is significant for correct species identification and demodecosis diagnostics. The list has been drawn up on the basis of data acquired in the period 1842−2020. It contains 122 valid species of parasite, including their hosts and geographic distribution, data on parasitism, as well as only the second record of Demodex sciurinus in Eurasian red squirrel Sciurus vulgaris in over 100 years since its initial discovery.
