Leporinus amae is known from the Rio Apuaê (type locality), Rio Canoas and Rio Caveiras tributaries of the Uruguay River basin, in Brazil. The original description of this species was mainly based on a single specimen lacking intraspecific variation in meristic and morphometric of most characters. We expand the range of distribution and report the first occurrence of Leporinus amae in Misiones Province, Argentina. Additionally, we provide a supplementary description of the species.

Originally identified as an ornithisichian dinosaur, Crosbysaurus has been found in New Mexico, Arizona, and the type locality in Texas. The genus has been reassessed by other workers in light of revelations about the postcrania of another putative Triassic ornithischian, Revueltosaurus. The understanding of Triassic dental faunas has become more complicated by the extreme convergence between pseudosuchian archosaurus and ornithichian dinosaur dental morphologies. We report here on a new specimen of Crosbysaurus from the Petrified Forest Member of the Chinle Formation at Comb Ridge in southeastern Utah. This new specimen is assigned to Crosbysaurus on the basis of the unique compound posterior denticles, mediolateral width, and curvature. While this specimen, MNA V10666, does not help resolve the affinities of Crosbysaurus it does represent an approximately 250 kilometer extension of the geographic range of this taxon. This is the first record of this taxon in Utah and as such it represents the northernmost known record of Crosbysaurus. This indicates that Crosbysaurus was not limited to the southern area of Chinle/Dockum deposition but instead was widespread across the paleoriver systems of the Late Triassic in western Pangea. The specimen we report on here was found in close association with a typical Late Triassic Chinle fauna, including phytosaurs, metoposaurs, and dinosauromorphs.

Atractus wagleri was described based on a single specimen from Humbo, Department of Boyacá on the western Cordillera Oriental of Colombia, and since its original description there is no further record for the species. In the course of examination of Colombian collections the holotype of the Atractus wagleri could not be found and it is probable that it was lost, but we found three additional specimens of this poorly known snake from localities relatively close to the type locality. In this paper, we describe these specimens, and report data on meristics, morphometrics, and hemipenial variation for the species.

Peyssonneliaceae represents a monophyletic clade of red encrusting algae classified Peyssonneliales. Molecular analyses have been important for revealing unknown diversity in this family, which includes small, cryptic organisms, frequently distinguished solely by discrete anatomical characters. Brazil however, remains virtually unknown. To assess this diversity, phylogenetic and barcoding analyses using rbcL, COI-5P and SSU data, as well as morpho-anatomical analyses were performed. Here we report the first occurrence of two genera on the Brazilian coast: Ramicrusta and Incendia, and describe three new species: Ramicrusta fujiiana sp. nov., Ramicrusta paradoxa sp. nov. and Incendia yoneshigueana sp. nov. Ramicrusta was resolved as a monophyletic clade in the three reconstructed phylogenies, and had congruent topologies. In the rbcL phylogeny, Ramicrusta fujiiana formed a well-supported clade sister to a well-supported clade including R. aranea (Vanuatu, type locality) and R. textilis (Jamaica, type locality). Morphological characters of R. paradoxa are not in agreement with the original description of the genus. Therefore, we present an updated and broader concept of Ramicrusta. Incendia was resolved as a monophyletic clade with full support for rbcL. Incendia yoneshigueana is in a sister relationship with I. glabra (Vanuatu, type locality). This study extends the distributions of Ramicrusta and Incendia, proposes three new species, and confirms the effectiveness of rbcL, COI-5P and SSU in inferring phylogenetic relationships and delimiting species in the Peyssonneliales. The integrative approach established clear taxonomic concepts for the studied genera and species, and identified useful characters for genera delimitation in Peyssonneliaceae.

A single specimen of the African spadefish,Tripterodon orbis, was landed in a gill net operating off Visakhapatnam on 13 December 2013. The morphometric and meristic characters of the recorded specimen are described and discussed herein. This is the first occurrence of the species from the north-east coast of India, exhibiting an extension in distribution from the southern to the northern region, along the Bay of Bengal.

Limnoperna fortunei (Dunker, 1857) is a small mytilid native to Southeast Asia. It was introduced in South America in early 1990 and has dispersed from Argentina to central Brazil, and until 2014 has been restricted mainly to the Paraná and Uruguay river basins. The present note reports the occurrence of Limnoperna fortunei for the first time in the São Francisco River basin in northeastern Brazil. The establishment of L. fortunei in these regions will require close attention from the government and also by society.

Embolemidae is a small family of chrysidoid wasps (Hymenoptera: Chrysidoidea) understudied in Ukraine. The cosmopolitan genus Embolemus is shown comprising only 32 extant and 2 fossil species in the world fauna: the actual check-list for the genus is given. Only two species had been previously registered in Ukraine. Embolemus ruddii was recorded at Western Ukraine and Crimea, and E. tauricus was described from Crimea based on a single specimen collected at 1910. In present contribution E. tauricus is recorded for continental Ukraine for the first time from the Zaporizhia Region. The specimen collected almost fully correspond to the original description of the species, differing only in the small features of coloration. The habitat of E. tauricus is briefly described.

Originally identified as an ornithischian dinosaur, Crosbysaurus harrisae has been found in New Mexico, Arizona, and its type locality in Texas, as well as in North Carolina. The genus has been reassessed by other workers in light of reinterpretations about the postcrania of another putative Triassic ornithischian, Revueltosaurus. The understanding of Triassic dental faunas has become more complicated by the extreme convergence between pseudosuchian archosaurs and ornithischian dinosaur dental morphologies. We report here on a new specimen of Crosbysaurus (MNA V10666) from the Chinle Formation at Comb Ridge in southeastern Utah. This new specimen is assigned to Crosbysaurus sp. on the basis of the unique compound posterior denticles, labiolingual width, and curvature. While MNA V10666 does not help resolve the affinities of Crosbysaurus, it does represent the extension of the geographic range of this taxon for approximately 250 kilometers. This is the first record of the genus Crosbysaurus in Utah and as such it represents the northernmost known record of this taxon. This indicates that Crosbysaurus was not limited to the southern area of the Chinle/Dockum deposition but instead was widespread across the Late Triassic paleoriver systems of western Pangea. The reported specimen was found in close association with a typical Late Triassic Chinle fauna, including phytosaurs, metoposaurs, and dinosauromorphs.

The species Lygosoma (Keneuxia) dubium was described by Franz Werner (1909) based on a single specimen from the Royal Natural History Cabinet (Königliches Naturalienkabinett) in Stuttgart, collection number 3651. According to the original description the specimen was collected by “Direktor Mayer” in Yokohama, Japan in 1897. Much later Nakamura & Ueno (1963) transferred the species to the Genus Dasia Gray, 1839, without further comments. Recently Uetz et al. (2018) questioned the type locality given by Werner (1909) and suggested that the name Lygosoma dubium is likely to be a synonym of Dasia grisea (Gray, 1845) referring to a personal comment of T. Hikida in 2014. However the actual taxonomic status of the species still remains unresolved.

Crassiplana albatrossi is redescribed on the basis of material collected in Patagonia (Argentina) and type material deposited in the USNM. The specimens have specific characters, showing tentacles; tentacular, brain and marginal eyes; genital pores in the posterior portion; male copulatory system with penis papilla; prostatic vesicle free, with strong muscular walls; internal epithelium of prostatic vesicle glandular and with conspicuous projections; seminal vesicle present; vagina very long and extending anteriorly up to pharynx; Lang’s vesicle absent; genito-intestinal duct present. Known geographic range is increased to include Patagonia (Argentina). Identity of Notocomplana palta is confirmed based on the presence of characters in the original description including: strongly muscular seminal vesicle, long, thin and muscular ejaculatory duct stretching into prostatic vesicle, which has a high and folded epithelium; conical penis papilla. A lectotype is designated from the material studied by Marcus and housed in the SMNH. Known geographic range of Notocomplana palta, known only from the type locality in south Chile, is enlarged to include Patagonia (Argentina), revealing its Magellanic affinities.
