Description
Notahypsibius pallidoides (Pilato, Kiosya, Lisi, Inshina & Biserov, 2011) gen. et comb. nov. Figs 1–7, Tab. 2, 3
Hypsibius pallidoides Pilato, Kiosya, Lisi, Inshina & Biserov, 2011: 13–15, fig. 7a–d (description).
Geographical distributionThis species was described from Kherson Oblast, South Ukraine (Pilato et al. 2011). Later it was recorded for the Minsk Oblast, Central Belarus (Pilato et al. 2012) and Sicily (Lisi 2015). My observations extend the distribution of this species to North-West Russia (St Petersburg and Karelia), Croatia and Austria (Carinthia). It should be noted that Dastych (1988) observed a configuration of the bucco-pharyngeal apparatus similar to N. pallidoides gen. et comb. nov. in some Polish specimens attributed by him to H. convergens (Dastych 1988: 147, pl. XXIa, c). Also, some of the microphotographs of the claws of Dastych’s specimens of H. convergens show a similarity to those described for N. pallidoides gen. et comb. nov. (Dastych 1988: pl. XXIi). So, it is very likely that the latter species is present among the tardigrade fauna of Poland. The species attributed to as “ H. convergens ” by Guil & Giribet (2012) is nearly identical to N. pallidoides gen. et comb. nov. in 18S and 28S gene sequences (see Genotypic differential diagnosis). In my opinion, this is evidence for the presence of N. pallidoides gen. et comb. nov. in Spain, but it was recently shown (Guidetti et al. 2019a) that closely related species can share an identical 18S rRNA haplotype. Thus, without analyses of the more sensitive barcode genes (particularly COI and ITS-2), and in the absence of morphological data, the possibility of the presence of another species similar to N. pallidoides gen. et comb. nov. in Spain cannot be excluded.
