Stonefly (Plecoptera) fauna in a mountainous area of Central Brazil: composition and adult phenology

Abstract

ABSTRACT. A survey of the stonef1y (Plecoptera) fauna of streams of the Almas River basin, Pirenópolis, Goiás State, Central Brazil, is presented as well as data of some factors that could affeet the temporal distribution of the adults. For checking adult phenology, light sources were used in three stations from June 1993 to Jully 1994. The sampled individuais were identified to species or morphospecies, as possible. ln this study , 30 I individuais belonging to the perlid genera Anacroneuria Klapálek, 1909, Kempnyia Klapálek, 1916 and Macrogynoplax Enderlein, 1909 were co llected. Adults of most species were eollected along lhe studied period, exeept for those of Kempnyia that were restricted to the warm-rainy season, the sarne pattem for this genus in southeastem Brazil. Although adults of most species were eolleeted along most of the studied period, the largest number of adults was eolleeted in the months with larger mean temperatures, showing a clear seasonality in abundanee.

Description of the larva and redescription of the adult ofKempnyia neotropicaJacobsen and Bianchi (Plecoptera: Perlidae) with biological notes

“…Kempnyia neotropica has a restricted flight period like most species of the genus (Froehlich 1991;Bispo et al 2002). The analysed materials in this study and in Froehlich (1991) prove the occurrence of K. neotropica adults between September and March.…”

Temporal distribution of Ephemeroptera, Plecoptera and Trichoptera (EPT) adults at a tropical forest stream: response to seasonal variations

“…All EPT adults that landed on the sheets were collected either with forceps or by hand and placed in an empty vial. All methods followed Bispo et al (2002). On each sampling occasion, the light trap was deployed for 5 h from 18:30 to 23:30 h. This duration was chosen according to preliminary work at the beginning of sampling.…”

“…No Brasil, está representada por quatro gêneros. Gripopteryx Pictet (17 espécies) e Tupiperla Froehlich (25 espécies) ocorrem desde o sul passando pelo sudeste até áreas montanhosas do nordeste e do Brasil Central (Froehlich 1993(Froehlich , 1998(Froehlich , 2016Bispo et al 2002;Bispo & Lecci 2011;Lecci & Froehlich 2011;Duarte et al 2014Duarte et al , 2019; Paragripopteryx Enderlein (14 espécies) possui distribuição similar àquela dos gêneros anteriores, porém não ocorre no Brasil Central (Froehlich 1994;Bispo & Lecci 2011;Duarte et al 2022); Guaranyperla Froehlich (três espécies) ocorre em regiões montanhosas do sudeste do Brasil (Froehlich 2001(Froehlich , 2015.…”
