https://www.selleckchem.com/products/c1632.html We examined and identified preserved specimens, skins, and photographs from a collection of 83 snakes from northern Thailand presenting the characters of the genus Hebius Thompson, 1913. They belong to at least six different taxa divided into five species including a new one described here, namely H. bitaeniatus (Wall, 1925), H. deschauenseei (Taylor, 1934), H. igneus David, Vogel, Nguyen, Orlov, Pauwels, Teyni Ziegler, 2021, Hebius khasiensis (Boulenger, 1890), and a series of specimens with strong similarities to H. khasiensis that are here preliminary identified as Hebius cf. khasiensis. Furthermore, we obtained a series of 21 different specimens in the most western strip of the region that we could not refer to any presently known species. We refer these specimens to a new species that we describe here. For each of these taxa, we provide the list of localities and specify the geographic range in northern Thailand. Lastly, we also discuss the diversity of the snake fauna of northern Thailand.The Hyalella comprises a group of freshwater amphipods endemic to the Americas. In Brazil, the greatest diversity of species known so far is concentrated in the state of Rio Grande do Sul, but recently discoveries were made in the neighboring state of Santa Catarina. The present work describes the first island species of the genus Hyalella in Brazil and the fifth with occurrence in the state of Santa Catarina. The species was found in streams of two watersheds, located at the Monumento Natural Municipal da Lagoa do Peri, an important environmental protection area on the island of Florianpolis, Southern Brazil. Hyalella insulae n. sp. shows the following characters inner face of propodus of gnathopod 1 with 7 serrate setae, gnathopod 2 with propodus ovate, peduncle of uropod 3 with 10 cuspidate setae, telson rectangular, wider than long, with 6 cuspidate setae and 2 plumose setae laterally close to each distal seta.
