The geographic distribution of Calomys laucha in Brazil, known only from the southern portion of Rio Grande do Sul state, up to the state’s Central Depression region, is extended approximately 350 km to the north with a new record at Faxinalzinho municipality, post Depression region in Rio Grande do Sul state. The species seems to be associated with dense shrubby vegetation in this area.

The two endemic, endangered species, Bacch­aris hypericifolia (Asteraceae) and Hypericum salvadorense (Hypericaceae), were known only for the Rio Grande do Sul state, in Brazil. In this paper we report two new occurrences of these species in Santa Catarina, expanding their geographic distribution to the north. Baccharis hypericyfolia and H. salvadorense were collected in areas of PPBio (Programa de Pesquisa em Biodiversidade) project. These novelties evidence the presence of knowledge gaps regarding the flora and little collecting effort in the grasslands from Southern Brazil.

ABSTRACT Ryegrass is a weed of annual cycle that is present in winter crops, in orchards and vineyards of the South region of Brazil. The species is normally controlled by the glyphosate herbicide, but the continuous use of this product caused the selection of resistant biotypes. The use of ACCase inhibitor herbicides is the main alternative for the control of this species, but it has not been satisfactory in some places, thus causing suspicion of resistance to this action mechanism. Thus, the objective of this paper was to evaluate the occurrence and geographic distribution of ryegrass biotypes that are resistant to the clethodim herbicide in the state of Rio Grande do Sul. For that, seeds of ryegrass plants that survived the application of clethodim were collected in crops from the north region of RS, summing up to a total of 152 samples from 72 cities. The biotypes were submitted to the application of 120 g i.a. ha-1 (maximum registered dose) and 60 g i.a. ha-1 de clethodim (half the maximum registered dose). According to the results, among the samples of ryegrass seeds collected, there were no biotypes resistant to the clethodim herbicide when the maximum registered dose was applied and in the stage of three to four leaves. However, there were biotypes with lower susceptibility that survived half the maximum registered dose.

Astyanax Fasciatus

Dendrorchis retrobiloba Volonterio & Ponce de León, 2005 was first described from the swim bladder of Astyanax fasciatus (Cuvier, 1819) from Montevideo, Uruguay. In this study, we necropsied specimens of A. aff. fasciatus collected from Lake Guaíba, in Rio Grande do Sul, Brazil, for the analysis of their helminths. The digeneans were identified as D. retrobiloba by their elongated body, oral sucker longer than ventral sucker, and 2 posterior lobes. This is the first report of D. retrobiloba in A. aff. fasciatus from Lake Guaíba and extends the known geographic distribution of this parasite.

The Brazilian scorpion Tityus serrulatus is recorded for the first time in the central region of Rio Grande do Sul, thus filling a gap of 567 km in its distribution. A specimen of the scorpion was collected in the urban area of the municipality of Santa Maria (29°43′51.31″ S, 053°48′5.74″ W) on 31 June 2014. A map was generated with the points of occurrence of the species in the state.
