Ephemeroptera from the Venezuelan Guayanas´s Uplands: Families Leptophlebiidae, Euthyplociidae and Oligoneuriidae

Abstract

As a continuation of a series of papers to improve the knowledge of the Ephemeroptera fauna of the Venezuelan Guayana's Uplands, an update of the families Leptophlebiidae, Euthyplociidae and Oligoneuriidae in the region is presented. As a result, Paramaka incognita sp. nov. is described, the female of Askola emmerichi is described for the first time, and the genera Askola, Hydrosmilodon and Leentvaaria, the subgenus Miroculis (Atroari) and the species Miroculis (M.) marauiae are recorded for the first time for Venezuela.

The morphology of the eggs in the Hermanella complex (Ephemeroptera: Leptophlebiidae)

“…The insects (preserved in 80% ethanol) were obtained from collection kept in the Museu de Entomologia da Universidade Federal de Viçosa (UFVB), Brazil and identified with aid of taxonomic keys and comparison with original descriptions (Polegatto and Batista, 2007;Lima et al, 2012;Nascimento and Salles, 2013;Domínguez et al, 2014;Salles et al, 2016). The eggs were removed from the abdomen of mature nymphs or adult females of eight species from five genera.…”

Exploring the Influence of Daily Climate Variables on Malaria Transmission and Abundance of Anopheles arabiensis over Nkomazi Local Municipality, Mpumalanga Province, South Africa

“…Furthermore, the approach has been identified as a most efficient method among the various methods developed to study nonstationary data [21–23]. The methodology has also been considered in many fields such as atmospheric sciences, geophysics, and climatology [24, 25], and epidemiology [26–28]. As defined in Fourier analysis, the univariate wavelet power spectrum can be broadened to analyze statistical relationships between two time series x ( t ) and y ( t ) by computing the wavelet coherence, using the following formula:Rx,yf,τ=|||〈〉|Wx,y()|fnormal,τWxf,τ1/2·Wyf,τ1/2,where 〈〉 denotes smoothing in both time and frequency, W x ( f , τ ) represents the wavelet transform of series x ( t ), W y ( f , τ ) is the wavelet power transform of series y ( t ), and W x , y ( f , τ )= W x ( f , τ ) · W y ( f , τ ) is the cross wavelet power spectrum.…”
