Estudo taxionômico dos Psephenidae (Coleoptera: Byrrhoidea) da Amazônia Brasileira

Abstract

Cinco espécies de Psephenidae, incluídas no gênero Pheneps, são assinaladas para a Amazônia brasileira, pela primeira vez: P. cursitatus Spangler; P. auariensis sp.nov.; P. leptophallus sp.nov.; P. roraimensis sp.nov. e P. simoides sp.nov. Detalhes de peças anatômicas do adulto, da larva, estruturas da terminália masculina são apresentadas para todas as espécies e são fornecidos novos dados sobre registros geográficos.

Diversity and ecological aspects of aquatic insect communities from montane streams in southern Brazil

“…They can also be associated to well preserved riparian vegetation (Bispo et al, 2006). Additionally, abiotic factors related to streams environmental condition, such as water temperature, electrical conductivity, pH, and current velocity are important drivers of their communities (Fernandez and Fonseca, 2001;Buss et al, 2004;Bispo et al, 2006;Merritt et al, 2008). Thus, the presence of EPTC may reflect the integrity of the entire aquatic insect community (Crisci-Bispo et al, 2007).…”

Belicinus Rhomboideus, a new genus and species of Psepheninae (Coleoptera: Byrrhoidea: Psephenidae) from Belize

“…Microphotographs were taken with a scanning electron microscope (Joel model JSM-5600LV, magnification 200X and 1000X). Four larval specimens and female adults of Belicinus gen. nov. were collected in the submerged part of the stones not exposed to the current, and their comparison with other known larval of Psepheninae allows the larvae to be associated with the adults of the new taxon (Bameul 2001;Lee et al 2003;Souza et al 2001;Spangler 1968). Drawings were made with a Leica MZ12.5 dissecting scope equipped with a camera lucida, with specimens in either ethanol or glycerine.…”
