“…In Dellagnola et al [ 62 ], Lecithodendriidae appeared to be the basal clade to other microphallids. In Fernandes et al [ 61 ], Phaneropsolidae is a sister clade to Lecithodendriidae, while Stomylotrematidae was left out of the analysis. In our analysis, the phylogenetic position of Stomylotrematidae was unstable between ML and BI analyses.…”

Morphological variability of trematodes from bats (Chiroptera) is poorly studied. Since the variability of adult digenean specimens may be rather high, morphological features are often insufficient for the identification of closely related species, and confirmation with the use of molecular data is required. The aim of our study was to combine the morphological and molecular phylogenetic analyses of several bat trematodes from the genera Gyrabascus and Parabascus (Pleurogenidae): Gyrabascus amphoraeformis, Gyrabascus oppositus, Parabascus lepidotus, Parabascus duboisi, and Parabascus semisquamosus, of which G. amphoraeformis and G. oppositus are little known in European Russia. We made detailed morphological descriptions of these trematodes from several definitive hosts, analyzed morphometric features, and generated new partial sequences of the 28S rRNA gene. A broad variability of trematodes of the genera Gyrabascus and Parabascus was revealed both from various host species and from specimens of the same host species. We propose a new taxonomic key for the identification of the studied species. Certain host specificity of these trematodes was revealed.

“…They are characterized by the presence of a unique morphological feature among lecithodendriids, namely the pseudogonotyl which is formed by thickened tegument on the sinistral side of the ventral sucker (Lotz & Font, 2008 ). Some authors have mistakenly referred to this structure as the genital pore and its function remains unknown (see references in Fernandes et al, 2022 ). Until recently, molecular data on Ochoterenatrema were lacking and its phylogenetic affinities were unknown.…”

“…Until recently, molecular data on Ochoterenatrema were lacking and its phylogenetic affinities were unknown. Fernandes et al ( 2022 ) provided the first DNA sequence data for 4 species of Ochoterenatrema from South and North America. Their phylogenetic analysis confirmed the monophyly of Ochoterenatrema and demonstrated its position as the closest taxon to the genus Lecithodendrium .…”

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.
