eggs. Finally, we observed type 1 uterine development in both materials of Ophiotaenia arandasi , contrary to Scholz et al. (2023b) that assigned type 2 for this species. All this newly provided data confirm that Ophiotaenia arandasi is a valid taxon.
Intraspecific variations have been reported in other Ophiotaenia species, mainly in characters such as: number of uterine diverticula, size of scolex, number and average size of testes ( Rego, 1962; Scholz et al., 2023a). However, we did not find intraspecific variation in the morphometric data among specimens of the present study, re-examination of type series and measurements provided in the original description of Santos and Rolas (1973) from E. miliaris . Additionally, despite some studies suggest that Ophiotaenia spp. exihibit host specificity ( Ammann and de Chambrier, 2008; de Chambrier et al., 2015), there are some reports of Ophiotaenia species in multiple congeneric hosts ( Santos and Rolas, 1973; de Chambrier, Vaucher and Renaud, 1992; de Chambrier et al., 2023). Our findings and those previous reports suggest that the host specificity of Ophiotaenia might be less strict than it was previously assumed.
The hosts registered for O. arandasi are phylogenetically related and their geographical distributions overlap ( Entiauspe-Neto et al., 2021). E. taeniogaster is more abundant in the Amazon and the northern Atlantic Forest, while E. miliaris is widely distributed in the Atlantic Forest, and other regions in brazilian territory, except Pampas Grasslands ( Nogueira et al., 2019). Our results support that sympatric hosts, might share some cestode taxa since they are exposed to similar ecological and phylogenetic conditions ( Aho, 1990; Krasnov et al., 2011).
Ophiotaenia karipuna n. sp. is the third species described parasitizing Erythrolamprus miliaris in Brazil. Although, O. arandasi and O. hyalina parasitize the same host species, they differ in various morphological aspects, primarily in the absence of the apical organ, present in O. karipuna .
Our study provides an ultrastructural analysis for O. karipuna n. sp. and O. arandasi . The SEM images showed details of the distribution of microtrichia on the tegument surface, on the upper edge of the sucker, luminal region of the suckers, and tegument surface between the suckers and the neck in both species. Additionally, it was possible to observe the presence of a vestigial apical sucker in O. karipuna n. sp., a unique characteristic of the new species compared to its Neotropical congeners.
The morphological data obtained by light and scanning electron microscopy strongly support the independent species-status of O. karipuna n. sp. from Erythrolamprus miliaris . The taxonomic validity of O. arandasi is confirmed based on a re-examination of the type series, and new collected specimens. We also provide the first ultrastructural analysis of the species, and new host and locality records. Therefore, considering the great diversity of snakes and the comparatively small number of Ophiotaenia species in Brazil, future studies of proteocephalids are valuable insights into the systematics and evolutionary history of the group.
