“…There has been a recent increase in studies of bat helminths in the Neotropics, in some contrast to the lack of recent similar studies in the Nearctic (Achatz et al, 2018 , 2020 ; Tkach et al, 2018 , 2019 ; Fernandes et al 2019 , 2021a , b , 2022 ; Panti-May et al, 2021 ; Moguel-Chin et al, 2023 , 2024 ; Kinsella et al, 2024 ). All these studies have invariably demonstrated that the helminth fauna of bats in the Western Hemisphere remains understudied and that these hosts likely harbor a much richer fauna of helminth parasites than currently known.…”

Ochoterenatrema Caballero, 1943 is a genus of lecithodendriid digeneans that prior to this study included 8 species parasitic in bats in the Western Hemisphere. Species of Ochoterenatrema possess a unique morphological feature in form of the pseudogonotyl on the sinistral side of the ventral sucker. In this study, we describe 2 new species of Ochoterenatrema from bats in Ecuador. The new species are readily differentiated from their congeners by a combination of morphological characters, including the distribution of vitelline follicles, length of oesophagus, sucker ratio and the body shape, among other features. We have generated partial nuclear 28S rDNA and mitochondrial cox1 gene DNA sequences from both new species. The newly obtained sequences were used to differentiate among species and study the phylogenetic interrelationships among Ochoterenatrema spp. The internal topology of the clade was weakly supported, although the cox1 tree was much better resolved than the 28S tree. Comparison of sequences revealed 0–1.2% interspecific divergence in 28S and 3.3–20.5% interspecific divergence in cox1 among Ochoterenatrema spp. The new findings demonstrate that bats in South America likely harbor multiple additional undescribed species of Ochoterenatrema. More extensive sampling from broader geographic and host ranges, especially in North America, should allow for a better understanding of the evolution of host associations and morphological traits of this lineage of lecithodendriid digeneans.

“…Species are phenotypically plastic and morphologically homogeneous, and the few available identification features can be affected by improper fixation ( Sitko, 1995 , 2013 ; Pojmańska, 2008 ; Tkach et al, 2018 ; Hildebrand et al, 2019 ). Recently, phylogenetic DNA markers have became available for some Dicrocoeliidae ( Hildebrand et al, 2015 , 2016 ; Aldhoun et al, 2018 ; Tkach et al, 2018 ; Waki et al, 2018 ; González-García et al, 2020 ; Suleman et al, 2020 ; Assis et al, 2021 ; Fernandes et al, 2021 ; Pinto et al, 2022 ). Nevertheless, more thorough species coverage is needed to enable species identification based on molecular diagnostics, mainly for larval Dicrocoeliidae.…”

During the health evaluation of 30 specimens of bats captured in periurban forest areas in the city of Belém-Pará, Brazil, a case of cerebral lariasis was observed. In the histopathological examination, adult lariae were found in the meningeal membranes in the brain tissue of Molossus barnesi (Molossidae) and classi ed morphologically as Litomosoides by the shape of the spicules -left spicule with a handle longer than the blade; right spicule curved, with a sclerotized heel supporting a dorsal notch; the area rugosa constituted by a ventral band of small longitudinal crests; tail rounded in males; long esophagus with a slightly glandular distal portion, and a muscular bent vagina. All the specimens lack a stoma (buccal capsule). We compared our larioids with the description and of specimens of Molossinema wimsatti. Morphological characters from M. wimsatti resemble the genus Litomosoides. Thus, we believe that M. wimsatti is a synonym of L. molossi Esslinger, 1973, and larioid specimens from material reported by Lichtenfels et al. (1981) and from de Souto et al. ( 2021) most probably correspond to Litomosoides. We suggest that the reduction of the buccal capsule could be attributable to the ectopic location. No evidence of tissue responses by the host were observed. This is the rst record of Litomosoides infecting brain tissue of Molossus barnesi from Brazil, representing a new host record. More specimens of bats should be examined in order to nd larioids in the brain and verify its taxonomic position using molecular techniques.
