A morphological re-evaluation of pachyseius humeralis berlese, 1910 (Acari, mesostigmata, pachylaelapidae)

Abstract

Based on features of the lectotype and newly collected specimens from Italy (Boboli Gardens, Florence), a morphological concept of Pachyseius humeralis Berlese, 1910 is revised and re-evaluated. New diagnostic character states important for recognition of the species are provided. A misidentified species, formerly widely published in Europe under the name P. humeralis, is established as a new species, Pachyseius sub-humeralis sp. n.
