Complementary description of two Anthoseius De Leon (Acari: Phytoseiidae) species based on their holotypes with new synonyms
Résumé
Due to the inadequacy of prior descriptions and the absence of redescriptions, studies on the taxonomy of the subgenus Anthoseius De Leon (Acari: Phytoseiidae) have become challenging and often cause confusion among taxonomists. Typhlodromus (Anthoseius) ghanii (Muma) and T. (A.) loralaiana (Muma) were described from Pakistan almost sixty years ago. Their original descriptions are not very detailed, being based on simple drawings and an absence of diagnostic characters that include measurements of dorsal setae. Most likely due to its inadequate description, T. (A.) ghanii was not recognized by acarologists and was therefore repeatedly described as a new species under different names. We examined the holotypes of T. (A.) homalii Gupta and T. (A.) sagaricus Karmakar et al. concluding both species to be junior synonyms of T. (A.) ghanii. Moreover, T. (A.) kuznetsovi (Denmark and Welbourn), described from Tajikistan, is proposed as a new junior synonym of T. (A.) loralaiana based on the examination of their holotypes. Hence, complementary descriptions of T. (A.) ghanii and T. (A.) loralaiana, based on their holotypes, are provided to facilitate species identification and to improve their diagnosis.
