Description

Viannaia arriaguensis Ramírez-Cañas, López-Caballero & Mata-López

Site of infection: Small intestine.

Host species: Didelphis virginiana and Philander vossi.

Localities: Mérida, Umán (Yucatán), Campeche (Campeche), and Chetumal (Quintana Roo).

Prevalence: Didelphis virginiana 83.33% (5/6), Philander vossi 100% (1/1).

Mean intensity: Didelphis virginiana 93 (range 47‒129), Philander vossi 1043.

Specimens deposited: CNHE 12874‒12877.

GenBank accession numbers: PP662458‒PP662460.

Comments: The morphology of the specimens matches the original description by Ramírez-Cañas et al. (2021). Synlophe with three sub-ventral cuticular ridges at midbody oriented from right to left, with the absence of lateral and dorsal cuticular ridges. Male body length 2,650 ‒9,040. Bursa sub-symmetrical, rectangular with pattern of type 2-1-2. Dorsal ray short and slender. Spicules simple, long (360‒428), thing, equal in length and shape (Figure 4A), representing 7.3‒8.7% of the body length. Gubernaculum 32‒55 long. Monodelphic female 4,850 ‒7,370 in total body length. Eggs ovoid, 52‒70 long by 32‒40 wide.

Viannaia arriaguensis was described based on specimens found in P. vossi (originally reported as P. opossum) from Chiapas, Mexico (Ramírez-Cañas et al. 2021). This is the first record of V. arriaguensis in D. virginiana as well as the first report in the Yucatán Peninsula.
