Stages in the Development of Choriopsoroptes kenyensis gen. et sp. n. (Acari: Sarcoptiformes: Psoroptidae), a Body Mange Mite from Captive African Buffalo, Syncerus caffer, in Kenya

Stages in the life cycle of Choriopsoroptes kenyensis gen. et sp. n. are described. The stages for both sexes consist of the egg, larva, protonymph, tritonymph, and adult, with the last 3 showing sexual dimorphism. The adult male forms an attachment pair with the female tritonymph by use of opposing...

Description
Summary:Stages in the life cycle of Choriopsoroptes kenyensis gen. et sp. n. are described. The stages for both sexes consist of the egg, larva, protonymph, tritonymph, and adult, with the last 3 showing sexual dimorphism. The adult male forms an attachment pair with the female tritonymph by use of opposing opisthosomal suckers. The new species differs from other Psoroptinae in many characters, but is immediately separated by its long piercing chelicerae (like Psoroptes) in combination with short tarsal unsegmented pedunculated caruncles (like Chorioptes and Psorochorioptes), a tarsal hook, and, in the adult male, diminutive opisthosomal lobes. The mites cause body mange on captive African buffalo, Syncerus caffer, but were not found on 20 wild buffalo. A few Psoroptes natalensis were also present with the new species on the captive buffalo. This constitutes a new host record for P. natalensis. The new species is only slightly smaller than P. natalensis and these 2 species sometimes formed cross-attachment pairs.
