Immature stages of many Brazilian Smicridea species remains unknown, and efforts to describe all life stages are required. In this paper, the larva and pupa of Smicridea (Rhyacophylax) gladiator Flint 1978, associated with adults through the metamorphotype method, are described and illustrated. In addition, the known distribution of this species is extended in the Brazilian Amazon Basin with new records from Amazonas state and the first record in Pará state. Information about its bionomics is also provided.

Flesh Flies

The white-sand enclaves in the Amazon Basin are small areas scattered through the tropical forest, with sandy and nutrient-poor soils and an unusual vegetation type. The insect fauna of this ecosystem is poorly known, especially in the eastern Amazon. The flesh fly fauna of an area of open herbaceous white-sand vegetation known as “Campo Redondo” in the municipality of Cametá, state of Pará, was surveyed, resulting in the discovery of 43 species in 11 genera representing the subfamilies Sarcophaginae and Miltogramminae. Four new species are described: Dexosarcophaga (Dexosarcophaga) campina sp. nov., Helicobia cametaensis sp. nov., Helicobia domquixote sp. nov., and Metopia fofo sp. nov. Lepidodexia (Lepidodexia) grisea Lopes and Lepidodexia (Notochaeta) setifrons (Lopes) are newly recorded from Brazil. Dexosarcophaga (Bezzisca) ampullula (Engel), D. (Dexosarcophaga) transita Townsend and Titanogrypa (Cucullomyia) larvicida (Lopes) are newly recorded from the Brazilian Amazon.

Precision Time

This paper investigates temporal interpretations in Pirahâ, a Muran language spoken in the Brazilian Amazon basin. The analysis assumes the neoReichen-bachian model of tense syntax proposed in Hornstein (1990) and argues that this model provides an elegant account of tense-related facts in Pirahâ, iff it is parametrized. Whereas Hornstein predicts that all tense systems will have a temporal reference point (R), this paper argues that languages may be parametrized as [+R] or [-R] and that this has important implications for their temporal syntax. Moreover, the paper also argues that it is no coincidence that the Pirahâ place little importance on precision time statements, or that the Pirahâ have difficulty translating such statements, since their language does not draw temporal distinctions based on R. The parametrization of R among the Pirahâ is argued to offer anew source of support for Sapir's linguistic relativity hypothesis.
