Body pyriform, minute, 225 (165–330) long and 123 (105–151) wide ( Figure 2A). Tegument unarmed. Oral sucker spherical, subterminal, 50 (50–51) long by 52 (50–56) wide. Ventral sucker in middle third of body, 55 (50–60) long by 69 (62–74) wide. Pharynx, oesophagus, and intestinal caeca not observed. Gonads in anterior half of hindbody. Testes postero-lateral to ventral sucker; right testis 42 long by 70 wide, left testis 55 long by 62 wide. Ovary median, post-testicular, 32 long by 53 wide. Vitellaria in hindbody, concentrated in lateral region, occupying almost entire left testis. Eggs 27 (25–30) long by 13 (11–15) wide. The closest species in morphology is  A. hastatidescribed from  Phyllostomus hastatus(Pallas)in Peru. However, we were unable to observe the characteristic unicellular glands located anterolateral to cirrus sac due to the poor condition of preservation of our specimens. The remaining species,  Anenterotrema liliputianum(Travassos),  Anenterotrema auritum(Stunkard),  Anenterotrema eduardocaballeroi(Freitas),  Anenterotrema freitasi(Caballero),  Anenterotrema mesolecitha(Marshall & Miller),  Anenterotrema iannaconei(Achatz, Cardenaz-Callirgos & Tkach),  Anenterotrema megacetabulum(Fernandes, Santos, Melo, Achatz, Greiman, Bonilla & Tkach),  Anenterotrema paramegacetabulum(Cacique, Cruces & Chero),  Anenterotrema kawsayense(Cacique, Cruces & Chero),  Anenterotrema stunkardi(Caballero & Grocott), and  Anenterotrema peruense(Cacique, Cruces & Chero), differ in shape and size of oral sucker, body length, and position of gonads ( Cacique et al.2023). This is the first record of  A. cf. hastatiin Mexico. 5034624302 Bauerus dubiaquercus MASL 18.53161 Ejido Adolfo Ruiz Cortines 1 -95.133804 Tuxtlas 3 332 CNHE 12134 151 Veracruz
