Molecular and Morphological Identification of Dermanyssoid Mites (Parasitiformes: Mesostigmata: Dermanyssoidea) Causatives of a Parasitic Outbreak on Captive Snakes

A parasitic outbreak caused by dermanyssoid mites in a herpetarium of the Metropolitan area of the Valley of Mexico is revealed. This outbreak was caused by Hemilaelaps triangulus (Ewing), but a second mite species, Ophionyssus natricis (Gervais), was found in low abundance. The parasitic load is an...

Description
Summary:A parasitic outbreak caused by dermanyssoid mites in a herpetarium of the Metropolitan area of the Valley of Mexico is revealed. This outbreak was caused by Hemilaelaps triangulus (Ewing), but a second mite species, Ophionyssus natricis (Gervais), was found in low abundance. The parasitic load is analyzed, and the morphological and molecular diagnostic characters to identify each of the two species involved are given. A barcode analysis is presented, and two more molecular markers are presented and analyzed. Hemilaelaps triangulus is recorded for the first time in Mexico, and this is the first record of massive infestation on captive snakes caused by ixodorhynchid mites, and DNA sequences of ixodorhynchid mites are publicly available for the first time.
