Background: Ligophorus Euzet and Suriano, 1977 is a specious genus of ancyrocephalid monogeneans parasitizing mullets around the world, with most species distributed in the western Pacific and the Mediterranean Sea. Only nine out of the 62 species in the genus have been reported from the Americas, and from them, only two have been sequenced.
Methods: We analyzed two species of Mugil (L.

Tyzzeria Allen, 1936 is a coccidian genus traditionally associated with Anseriformes, although there are descriptions of Tyzzeria spp. from junglefowls, snakes, skinks and mice. In this sense, the current study performs a taxonomic review of Tyzzeria spp.

Phrynops geoffroanus has a wide distribution in South America, living in aquatic environments such as rivers, streams, and lakes, in natural and urban environments. In this work, the plastron formula and the diversity index associated with the allometric condition are established for the species. For the morphometric analyses, the following were calculated: standard error, class intervals, sample standard deviation, principal component analysis, and allometry.

Anatomical knowledge is fundamental for all species. In particular, myology allows a deeper understanding of ecomorphology-especially for those species hard to observe in the wild-and may be an important source for phylogenetic information. In this study, we analyzed the myological variation of the musculature of the shoulder and arm of the forelimb in species of the suborder Feliformia and its relationship with the phylogenetic history and the locomotor behavior, habitat, and predatory habits of the species within this group, using Leopardus geoffroyi as a case study.

The superfamily Mantispoidea (Insecta: Neuroptera) includes the families Berothidae, Rhachiberothidae and Mantispidae. Among these taxa, the last two are collectively known as Raptorial Mantispoidea due to the presence of grasping forelegs for predatory habits. The Mantispidae classically included the subfamilies Symphrasinae, Drepanicinae, Calomantispinae and Mantispinae, yet recent research challenged this classification scheme as well as the monophyly of this family resulting in Symphrasinae being transferred to Rhachiberothidae.
