Syphacia sp. (2)
Site of infection: Caecum and large intestine
Host species: Reithrodontomys gracilis
Localities: Kuncheil cattle ranch (Yucatan)
Specimens deposited: CNHE 12029‒30
Comments: The specimens found in R. gracilis had a cuticle with fine transverse striations, fields between transverse striations with shallow longitudinal depressions; a cephalic plate laterally-elongated in females; deirids present in females; cervical alae poorly developed ( Figure 5H View FIGURE 5 ); lateral alae absent; male spicule 60 long; female tail 315‒550 long; females with not prominent vulva; and eggs 85‒108 long by 25‒ 35 wide ( Figure 5I View FIGURE 5 ). Among the eight species of Syphacia with cervical alae ( Sy. carlitosi , Sy. alata , Sy. obvelata , Sy. peromysci , Sy. samorodini, Sy. p. rauschi, Sy. sigmodoni , and Sy. hodarae ), our specimens can be differentiated from Sy. carlitosi , Sy. alata , Sy. obvelata , Sy. samorodini , and Sy. hodarae by having deirids. In addition, the species from R. gracilis has a longer spicule than that of Sy. peromysci (57‒70), Sy. p. rauschi (56) and Sy. sigmodoni (64). Based on these findings, we consider that our specimens likely represent a new, undescribed Syphacia species.
This is the first helminthological record for R. gracilis .
