Abstract
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.
Highlights
Phytoseiid mites have received considerable attention because of their biocontrol potential
Fifty-three species are recorded from Taiwan (Ehara, 1970; Lo, 1970; Tseng, 1972; 1973; 1975; 1976; Chang and Tseng, 1978; Tseng, 1983; Ho and Lo, 1989; Ho et al, 2003)
The plant and animal quarantine work was transferred from Bureau of Commodity Inspection and Quarantine to the newly established Bureau of Animal and Plant Health Inspection and Quarantine (BAPHIQ) since 1998 and BCIQ was renamed to Bureau of Standards, Metrology and Inspection (BSMI)
Summary
Phytoseiid mites have received considerable attention because of their biocontrol potential. Yi-Hsiung Tseng provided the most complete survey of phytoseiid mites in this country from the 1970s to the early 1980s; he recorded 47 species including 20 newly described endemic ones. We re-described Amblyseius bellatulus adding characteristics that were not described in Tseng (1983) and we designated the specimens collected as neotype. These specimens were compared to the elements provided in Tseng (1983). A description of the male (unknown until now) is provided
