Physocephalus sexalatus

Physocephalus sexalatus (Molin) Infection site: Stomach and intestine Localities: Calcehtok and Homún Prevalence (%) and mean intensity: Calcehtok 4.8 and 1.5 (1‒1.6). Homún 3.1 and 1.7 (1‒2.5) Specimens deposited: CNHE-12322 and NHM 2025.8.13.14 GenBank accession number: PX232576 (28S) Comments: Based on eight encysted larvae. Cephalic region with two (ventral and dorsal) conical projections (Figure 5I). Head papillae well-defined, composed of six internal labial papillae and four cephalic papillae (Figure 5H). The funnel-shaped oral cavity passes into a narrow pharynx. Tail short, terminating in a small knob bearing spike-like projections (Figure 5J). Body, 1075 ± 229.3 (848‒1500) × 65 ± 9 (60‒80). Esophagus length 577 ± 139 (430‒760): muscular esophagus 186 ± 74 (80‒285) long and glandular esophagus 391 ± 108 (205‒550) long. Tail 47 ± 6 (42‒60) long. The morphology and measurements of the specimens correspond to the third-stage larvae of P. sexalatus (Kirillov & Yu Kirillova 2021). This species has been recorded in P. mesoamericanus, P. fulvus, B. plicata, Glossophaga mutica Merriam and Micronycteris microtis Miller from Morelos (see complete references in Jiménez et al. 2017). This is the first record of P. sexalatus from bats in Yucatán.
