Amblyseius bellatulus Tseng (Acari: Phytoseiidae): neotype designation with first description of a male

International audience; Yi-Hsiung Tseng provided fundamental information of phytoseiid fauna in Taiwan. However, according to an exclusive interview, all specimens included in Tseng's collections were lost after his retirement; therefore, more than 20 holotypes are now lost. To ensure stability in nomenclature, designation of neotypes is thus necessary. In this study, we re-described a known species, Amblyseius bellatulus Tseng 1983, by collecting phytoseiid mites from the original type locality and the entirely of Taiwan. Because the morphology of the collected specimens is highly similar to that of specimens used for describing the species, we designated a neotype and redescribed female specimens, as well as male specimens, which have not been described before.
