The Lacantun Catfish, Lacantunia enigmatica, is reported for the first time in the Usumacinta river basin in Guatemala. Two specimens were collected in the Usumacinta tributaries Río La Pasión and Río Negro, which are characterized by seasonally fast-flowing deep channels and high fluctuations in water-level. We present a map with new records, and a brief description, and images of the specimens collected.

There is extensive research of the Ephemeroptera communities taxonomy and ecology in the Andean region of Colombia. However, other regions such as the Orinoquia have been insufficiently studied. From this region, in the Meta department, four species have been registered: Varipes lasiobrachius Lugo-Ortiz & McCafferty, Coryphorus aquilus Peters, Miroculis (Atroari) colombiensis Savage & Peters and Tricorythopsis rondoniensis (Dias, Cruz & Ferreira). The main objective of this study is to report for the first time for this region the species: Mayobaetis ellenae (Mayo), Hydrosmylodon primanus (Eaton), Haplohyphes baritu Domínguez, Camelobaetidus edmundsi Dominique, Mathuriau & Thomas and Nanomis galera Lugo-Ortiz & McCafferty.

Acanthonus armatus Günther, 1878 is reported for the first time in the southwestern Caribbean region, off Colombia. Remote Operate Vehicle videos and towed camera still photographs captured 13 images of A. armatus between 2215 and 2564 m. These are the first records of the species in the Caribbean continental coast of Colombia, representing a range extension to the southwestern Caribbean region, since previous records are from the northeastern Caribbean. Some photos of the specimens and the current distribution of the species in the Caribbean region are provided and reviewed.

The New Zealand mudsnail Potamopyrgus antipodarum (Gray, 1843) has been considered as one of the most invasive mollusks worldwide and recently was listed among the 50 most damaging species in Europe. In the present paper, we report for the first time the presence of P. antipodarum in the Maule river basin, Chile. The identity of the species was based on anatomical microdissections, scanning electron microscopy comparisons, and DNA barcode analysis. This finding constitutes the southernmost record of the species until now in this country and South America.

As a result of a SEM study of phytoplankton, the first data on centric diatom species composition in Bolshoye Toko Lake, Yakutia, were obtained. Ten species (Aulacoseira — 5, Cyclotella — 1, Discostella — 1, Handmannia — 1, Pliocaenicus — 1) were found, and one taxon from the genus Pliocaenicus was identified to the genus level. Of these, nine taxa are reported for the first time in the water bodies of the Aldan River basin and Discostella guslyakovyi in Yakutia.

Mexican Populations

In a recent trip to southern Mexico, Anthoceros subtilis and A. telaganus were recorded for the first time in Mexico and the American continent. Several previous records of A. subtilis were from Asia and one from Africa, and A. telaganus is known only from Indonesia. The new range extension of these two species is reported and the species are described and illustrated.                 Mexican populations of A. subtilis are characterized by small brown spores (26–42 μm), similar ornamentation on proximal and distal spore surfaces with papillate to tuberculate projections. Anthoceros telaganus is characterized by larger black spores (32–53 μm) with a smooth strip along the trilete mark on the proximal surface. Molecular genetic sequencing is needed to test whether Asian and American populations of these morphologically similar but geographically disjunct taxa are conspecific.

The known range of S. apiculata Marshall and Buck, 2009, previously known from Amazonian Peru and Ecuador, is extended for the first time to Brazil. The phylogenetic tree and key of Marshall et al., 2009 are emended to include the new species and new information on S. papaveroi.

Aglaoctenus oblongus (C. L. Koch, 1847) is recorded for first time in Entre Ríos province and new records for Buenos Aires province (Argentina) and Montevideo (Uruguay) are provided. The distribution of A. lagotis (Holmberg, 1876) is updated with first time records for the Argentinean provinces of Jujuy, Salta, Chaco, Formosa, La Rioja, Tucumán, Santiago del Estero, San Luis and Entre Ríos, new localities in the provinces of Misiones, Corrientes, Santa Fé and Córdoba.

Distribution patterns of most of the 20 Neotropical freshwater turtles belonging to the family Chelidae are usually based on few locality records. We here report on vouchered records of three species of the chelid genus Mesoclemmys in the Brazilian state of Mato Grosso. Presence of M. vanderhaegei is confirmed for the Amazon River Basin, and M. gibba and M. raniceps are recorded in Mato Grosso for the first time.
