Etymology + + +The specific epithet + +bialoviensis + +refers to the geographic name (Białowie˙za) of the host locality. + + + + + +3.4. Infestation and location in the host + + + + +Demodex bialoviensis + +sp. nov. +was noted in 3 (prevalence 25%) European bison, with a density of 1.9 per +1 cm +2 +; 51 ( +12 males +, +34 females +, and 5 deutonymphs) individuals were noted. The demodecid mites were found in the nasal skin region. The observed mites did not cause any skin lesions in the examined bison. + + + + + +3.5. Differential diagnosis + + + +Compared to + +D. bisonianus + +previously described in bison ( +Kadulski and Izdebska, 1996 +; Izdebska, unpublished data), + +D. bialoviensis + +sp. nov. +is much smaller, with a different body shape and proportions. In addition, + +D. bialoviensis + +sp. nov. +shows a clear sexual dimorphism: the males are much smaller ( +Tables 1 +and +2 +, +Fig. 1 3 +). + + +The gnathosoma of + +D. bisonianus + +is trapezoidal, with a length less than the width at the base; in + +D. bialoviensis + +sp. nov. +it is rectangular, almost square, with a length close to the width at the base. Supracoxal spines in + +D. bisonianus + +are relatively small, conical, situated in the anterior part of the basal segment of gnathosoma, directed vertically, while in + +D. bialoviensis + +sp. nov. +they are relatively larger, wedge-shaped, + + + + +Fig. 3. + +Demodex bialoviensis + + +sp. nov. +(A, male; B, female) and + +Demodex bisonianus + +(C, female), scaled. + + + +situated in the central part of the basal segment and directed horizontally (medially and slightly oblique). On the terminal segments of the palpi, two larger spines and one small spine are present in + +D. bisonianus + +, and three forked spines of different sizes in + +D. bialoviensis + +sp. nov. +Subgnathosomal setae are located on the both sides in the lower half of the pharyngeal bulb in + +D. bisonianus + +, and at the anterior part of the pharyngeal bulb in + +D. bialoviensis + +sp. nov. +The legs of + +D. bisonianus + +are very massive, clearly projecting beyond the margin of the podosoma, and the tarsi of the legs are equipped with very large (ca. 9–10 long), strongly forked claws; in contrast, the legs of + +D. bialoviensis + +sp. nov. +are relatively smaller, with more delicate (4–5 long) and less forked claws. + + +The posterior edges of the IV pair of epimeral plates in + +D. bisonianus + +females is V-shaped, while in + +D. bialoviensis + +sp. nov. +it is deeply arched. The aedeagus of + +D. bisonianus + +males is much longer, located at the level of the II-III pair of epimeral plates, while in + +D. bialoviensis + +sp. nov. +it is shorter, stocky and located at the level of the II-IV pair of plates. The opisthosoma is narrow and long, cylindrical, rounded at the end in + +D. bisonianus + +, but tapers distinctly posteriorly in + +D. bialoviensis + +sp. nov +, with a sharp or slightly rounded end. The opisthosomal organ is absent in + +D. bisonianus + +, but present in + +D. bialoviensis + +. The typical microhabitat is also different: + +D. bisonianus + +is found in the Meibomian glands of the eyelids, and + +D. bialoviensis + +sp. nov. +in the nasal skin region. + + +In contrast, the shape of + +D. bialoviensis + +sp. nov. +resembles that of + +D. tauri +Bukkva, 1986 + +from domestic cattle + +Bos taurus +Linnaeus, 1758 + +. However, + +D. tauri + +is smaller, differs with regard to the shape of the gnathosoma ( + +D. tauri + +– rectangular, length less than width at the base; + +D. bialoviensis + +sp. nov. +– square with width close to length, if rectangular, length greater than width at base), and important taxonomic features, such as the location and shape of supracoxal spines ( + +T. tauri + +– smaller, spatulate), spines on palpi ( + +D. tauri + +– 2 similar, forked and one single), and the subgnathosomal setae ( + +D. tauri + +– elongated structures located on both sides of the middle part of the pharyngeal bulb are visible); the shape of epimeral plates is also different, especially the IV pair of the female, only being slightly arched at the posterior edges; the shape of the aedeagus (straight, narrower, located a slightly lower). In addition, its typical microhabitat is the skin around the eyes. + + + + \ No newline at end of file
