Trichuris silviae Panti-May & Robles


Trichuris silviae Panti-May & Robles  

Site of infection: Caecum

Host: Heteromys gaumeri  

Locality: Xkalakdzonot

Prevalence and mean intensity (range): 75.0% (6/8) and 3 (2–59)

Specimens deposited: MLP-He 7428 and CNHE 10704

Comments: The specimens examined in this study had characteristics described by Panti-May & Robles (2016) of trichurids from H. gaumeri   , i.e. males with spicular tube; spicule 1471–1732 long; proximal cloacal tube 187–236 long, united laterally to a distal cloacal tube 93–121 long; cylindrical and spiny spicular sheath; females with non-protrusive vulva and eggs 57–63 long by 30–32 wide. Notably, specimens from only one host had spicular sheaths with distal spherical bulge. However, the posterior length/spicular length ratio was similar.

Trichuris silviae   has only been reported from H. gaumeri in Tzucacab   , Yucatán (approximately 65 km from this new locality record) (Panti-May & Robles 2016).
