Eutrichophilus cordiceps Mjöberg, 1910 (Ischnocera: Trichodectidae) in Spiny Tree Porcupines (Coendou villosus): New locality records and the first molecular evidence of association with Bartonella sp.

The chewing louse genus Eutrichophilus Mjöberg has 19 species only associated with porcupines (Rodentia: Erethizontidae). Of these species, E. cercolabes, E. cordiceps, E. emersoni, E. minor, E. moojeni, and E. paraguayensis have been recorded in Brazil. In the present study, we report E. cordiceps for the first time in the São Paulo State (Bauru Municipality) and for the second time in the Santa Catarina State (Lages Municipality), providing scanning electron images and light microscopy for the eggs, as well as the first molecular data (18S rRNA) for the genus. Additionally, Bartonella sp. was detected for the first time in this chewing lice species.

Contribution to the knowledge of Parichoronyssus bakeri Morales-Malacara and Guerrero, 2007 (Mesostigmata: Macronyssidae): new locality and host-association records with additional molecular data

The mite genus Parichoronyssus Radovsky (Mesostigmata: Macronyssidae) comprises twelve known species found parasitizing bats in the New World. This study aimed to identify morphologically and molecularly macronyssid mites collected from bats and kept as backlog in the tissue bank (-80C) at the Acarological Collection of the Butantan Institute (IBSP). After the examination, the material was listed and identified as Parichoronyssus bakeri Morales-Malacara and Guerrero. Here, we were able to provide diagnostic microscopic images for the females of this species, as well as molecular information (18S rRNA and 16S rRNA) that were deposited in Genbank for reference. New locality records were also provided for P. bakeri in Rio de Janeiro and Rondônia States, Brazil.
