Summary: Diablophthalmus, a new genus, is described based on two new species, D. wygodzinskyorum sp. n. and D. marmoratus sp. n., found in P??ramo habitats in Colombia. These insects are the first recorded members of the Megophthalmini tribe from South America. The article discusses their morphological convergent features shared with other soil-dwelling Membracoidea.

Summary: This study investigated the biological basis of cannibalism in the native South American fish species Pseudoplatystoma reticulatum. The study found that cannibals are able to ingest prey ranging from 77% to 85% of their own size, and the results contribute to advancing rearing technologies for native fish species.

Summary: The newly proposed genus Megancestus includes only one species, Megancestus carpiodi, which is a stenoxenous parasite found mainly in carpsuckers and quillback in North America. This species differs from other caryophyllidean tapeworm genera by the structure of its reproductive organs.

Summary: A hyperproducer isolate of Paraboeremia sp. was obtained from the Las Yungas rainforest in Argentina, representing the first native reported species of this genus in South America. Through genetic and morphological analyses, a new South-American species, Paraboeremia yungensis, was described and proposed based on distinctive features from previously described species within the genus.

Summary: This study describes a new species of Diphyllobothrium, Diphyllobothrium sprakeri n. sp., first found in California sea lions from the Pacific coast of North America. It also confirms that South American sea lions from Argentina, Chile, and Peru serve as an additional host. Additionally, it revealed the first coinfection of two diphyllobothriid species in sea lions from the Southern Hemisphere.

Summary: The newly discovered Grillotia sasciae n. sp., recovered from the spotted skate off the south coast of the Western Cape in South Africa, shares similarities with species in the Grillotia subgenus, but possesses distinctive characteristics at both morphological and molecular levels.

Summary: A new species of tapeworm, Bothriocephalus kupermani n. sp., is described based on morphological and molecular data. It is found to mainly parasitize pumpkinseed and green sunfish. The new species differs from its North American congeners mainly in the shape of its scolex and the presence of vitelline follicles in the ovarian and uterine areas. It appears to be associated with Lepomis sunfishes.

Summary: Two new species of the genus Chondrochelia, Chondrochelia caribensis sp. nov. and Chondrochelia winfieldi sp. nov., were described from the Mexican Caribbean and the Gulf of Mexico. The genetic divergence values between species supported the morphological data. The distribution range of two species was expanded, while the supposed distribution of C. dubia in the Mexican Caribbean and the Gulf of Mexico was rejected. The characteristics of Chondrochelia algicola were redescribed based on type material.

Summary: Acantholeberis smirnovi, a new species of cladocera, was recently discovered in the Andean habitats of South America. This species differs morphologically, ecologically, and biogeographically from other species in the region. It is adapted to live in acidic water bodies, but the newly discovered species is found in temporary ponds near the Atlantic Ocean in Brazil, which is unique compared to other species.

Summary: Since 2008, the systematics of Terrarana frogs has been revised, resulting in the discovery of new genera such as Tachiramantis. This discovery has raised questions about the relationships between Tachiramantis and Pristimantis species. Through DNA sequence analysis and examination of morphological characteristics, the researchers have confirmed the placement of Tachiramantis in Craugastoridae and its monophyly, as well as identified a new genus within the highly endemic Glade.

Summary: This study reports the discovery of three new species of genus Bicorniphontodes in Korean waters, and reconstructs their phylogenetic relationships through morphology analysis. The monophyletic status of the new species is supported by morphological characteristics and comparisons, allowing for easy differentiation of the species based on various features.

Summary: A study on South American species of the moss genus Syntrichia discovered a new species, described as S. hosseusii, rescued S. campestris and Tortula chubutensis from synonymy as a distinct species in Syntrichia, and revealed a new trait in S. polylepidis.

Summary: This study examines geographic diversity within the acoustically divergent but morphologically conserved south-eastern Australian smooth frog complex and evaluates gene flow across a narrow hybrid zone. The findings reveal the presence of a new species restricted to the Otway Plains and Ranges in Victoria, which forms a stable hybrid zone with Geocrinia laevis.

Summary: The discovery of Pomphorhynchus sphaericus in new localities from La Plata River led to a reevaluation of the species using a taxonomic integrative approach. Despite observed morphological differences, molecular analysis confirmed that Pomphorhynchus individuals are conspecific with high phenotypical plasticity. This species is the first South American species to be analyzed at a DNA level, with molecular analysis relating it to P. bulbocolli and P. purhepechus.

Summary: This study provides a first-time description of the internal ultrastructure of the scolex and the histochemical composition of the apical glands in two South American proteocephalidean cestodes. Scanning and transmission electron microscopy were employed to observe the tegumental ultrastructure, while histochemical techniques were used to determine the types of gland secretion. Two types of glands were identified in the scolex, and the microtriches pattern for one species was confirmed, while for the other species, it was described for the first time. The presence of sensory receptors and the systematic value of certain characters were also discussed.

Summary: During a parasitological survey, a new species of Hedruris genus was discovered in the stomach of Synbranchus marmoratus Bloch from the Parana Guazu River, Parana River basin in Argentina. The new species, Hedruris anguila sp. nov., is morphologically distinct from other Hedruris species. This is the first time that a member of the family Hedruridae has been found parasitizing a species of Synbranchidae.

Summary: This paper describes a new parasitic genus called Diegloglossidium maradonai, which was found in the intestine of Hoplosternum littorale in the La Plata River basin. The genus is morphologically similar to members of Alloglossidiidae and Macroderoidiidae, but can be differentiated by certain morphological features. Molecular analysis also confirms its classification in the Alloglossidiidae family. The presence of a deeply lobed ovary is one of its notable characteristics.
