40% male and 60% female), found in this study, would be consistent with a sex ratio pattern reported for Brazilian Corydalinae (Azevedo, 2009), but data differ from reports on Sialidae and Chauliodinae (Table 1).
Such sex ratio patterns would be congruent with an old hypothesis of the relationship of Sialidae being closest to Chauliodinae (Weele, 1910), which is supported by a morphological phylogeny (Contreras-Ramos, 2004); however, this hypothesis does not agree with the accepted monophyly of Corydalidae (Table 1; Glorioso, 1981; New and Theischinger, 1993), nor with more current phylogenetic studies (Aspock el al., 2002; Wang el al., 2012; Liu el al., 2016).
Alderfly (Neuroptera: Sialidae) flight periods, sex ratios, and habitat use in a Virginia freshwater tidal marsh, low forest, and their ecotones.
Megalopterans are among the most primitive of winged insects in the world (Aspock et al., 2001) and include two families: Corydalidae (dobsonflies and fishflies) and Sialidae (alderflies).
The family Sialidae includes 10 (extant and fossil) genera worldwide (number of species in parentheses; J.
New species and new state records of Sialis (Neuroptera: Sialidae).
