Phaneropsolidae gen. sp.

Infection site: Stomach

Localities: Calcehtok and Homún

Prevalence (%) and mean intensity: Calcehtok 1.6 and 1 (1). Homún 1.6 and 1 (1)

Specimen deposited: CNHE-12312

Comments: Based on two specimens. Body slightly oval, 310–490 × 222–320 (Figure 2D). Oral sucker subterminal, 80–150 × 100–180. Ventral sucker 75–120 × 90–125. Pharynx not observed. Genital pore in forebody. Testes post-ovarian at level of mid-body; right testis 48 × 70, left testis 45–90 × 80–128. Ovary pretesticular, 42–90 × 60–95. Vitellarium extending from oral sucker to anterior part of testes. The uterus covers the posterior third of body. Eggs 10–11 × 5–6.

The examined specimens have the main characteristics of Phaneropsolidae (Bray et al. 2008), namely, a genital pore sublateral, a pretesticular ovary, and the vitellarium in clusters. Due to the poor conditions of the specimens, some morphological characteristics (e.g., cirrus sac) could not be clearly observed; therefore, we prefer not to assign the trematodes to a specific level. This group of trematodes has been recorded in several bats belonging to the families Mormoopidae, Natalidae, Phyllostomidae, Molossidae, and Vespertilionidae from several countries in the Neotropics (see the complete references in Santos & Gibson 2015; Caspeta-Mandujano et al. 2017).
