Carolinensis peromysci (Durette-Desset)

(= Boreostrongylus peromysci Durette-Desset )

Site of infection: Small intestine

Host: Peromyscus yucatanicus

Locality: Paraíso

Prevalence and mean intensity (range): 20% (1/5) and 1 (1)

Specimens deposited: MLP-He 7440

Comments: The infected mouse harbored only one female specimen. The morphological and metrical characteristics observed in our material agreed with the original description of females given by Durette-Desset (1974) for the parasites found in Podomys floridanus (Chapman) and Peromyscus gossypinus (Le Conte) , i.e. synlophe with 16 ridges at midbody and morphology of the posterior end, including the presence of a wide cuticular fold partially covering the posterior end and leaving free the tail sensu stricto; conical tail, without a mucron, and tail length about half length of the vulva-posterior end distance.

Four species of Carolinensis have been reported in México: Carolinensis carolinensis (Dikmans) from Peromyscus maniculatus (Wagner) in Hidalgo (Pulido-Flores et al. 2005), Carolinensis huehuetlana Falcón-Ordaz & Sanabria Espinoza , from P. difficilis in Hidalgo (Falcon-Ordaz & Sanabria Espinoza 1996) and Peromyscus mexicanus (de Saussure) in Hidalgo (Falcón-Ordaz et al. 2013), Carolinensis perezponcedeleoni Jiménez from Nyctomys sumichrasti (de Saussure) in Veracruz (Jiménez 2012), and Carolinensis petteri (Denke) from P. mexicanus in Veracruz ( Denke 1977). This is the first report of C. peromysci in México and of Carolinensis in P. yucatanicus .
