Brown-lacewings (Insecta: Neuroptera: Hemerobiidae) from Brazilian savannah in Central Brazil

Abstract

In this study were documented the species of brown-lacewings (Neuroptera: Hemerobiidae) found at Parque Nacional da Chapada dos Veadeiros, in Alto Paraíso de Goiás, state of Goiás and at Parque Nacional Grande Sertão Veredas, in Chapada Gaúcha, state of Minas Gerais, both in Brazil, based on a survey carried out with Malaise traps between February 2018 and May 2019. During the samplings 60 specimens of hemerobiids were captured, being 26 of Nusalala tessellata (Gerstaecker, 1888), 13 of Nomerobius argentinensis González Olazo, 1990, eight of Sympherobius amazonicus Penny & Monserrat, 1985, six of Megalomus impudicus (Gerstaecker, 1888), five of Hemerobius hernandezi Monserrat, 1996, one Nomerobius cuspidatus Oswald, 1990 and one of Notiobiella sp. Nomerobius argentinensis and Nom. cuspidatus are reported by the first time to Brazil and H. hernandezi, M. impudicus, Notiobiella sp. and S. amazonicus to the state of Goiás, Brazil.

Diversity and temporal variation of brown lacewings (Neuroptera, Hemerobiidae) from Atlantic rainforest areas in southeastern Brazil

“…These results differ from those obtained by Cancino-López et al (2021) in an altitudinal gradient at the Tacaná volcano in Mexico, where approximately 90% of the hemerobiids collected belonged to Hemerobius. Lara and Perioto (2021) reported that the total sampling effort for the capture of each Hemerobiidae specimen in areas of Brazilian savanna in the state of Goiás was 91.3 trap days, about 1.5 times higher than that recorded in this study (58.2 trap days). These results may be related to the need for intense and long-term efforts for Hemerobiidae sampling.…”

“…In Brazil, Nusalala and Hemerobius were reported in several studies carried out in agricultural Freitas, 2002, 2003;Lara et al, 2008Lara et al, , 2010Lara et al, , 2020Melo et al, 2020) and wild environments (Oliveira et al, 2013;Lara and Perioto, 2021;Schuster and Machado, 2021), and in most of them, Nusalala was the most abundant genus. However, in all these studies, Megalomus, Notiobiella and Sympherobius are genera, so far, poorly represented in population surveys conducted by the authors in agroecosystems and wild environments.…”

“…In Brazil, Oliveira et al (2013) reported that the highest frequencies of Nusalala in areas of Brazilian savanna and gallery forest areas in the state of Minas Gerais occurred in winter. Lara and Perioto (2021) studied the hemerobiids in areas of Brazilian savanna in the state of Goiás and found that the higher capture frequencies occurred in the fall and winter. In the state of Minas Gerais, Silva et al (2015) reported that the highest frequencies of Hemerobius in semi-deciduous and riparian forests occurred in the spring and summer, while Oliveira et al (2013) recorded these predators in late winter.…”

The extant fauna of Neuroptera (Insecta) from Brazil: diversity, distribution and history

“…Hemerobiids display the lowest percentage of endemic species for any Brazilian neuropteran family, only 19% (five species). The Brazilian species were listed by Lara and Perioto (2016) and complemented by more recent discoveries by Lara and Perioto (2021). Unfortunately, there is no identification key comprising all Brazilian species of brown lacewings, but there are regional keys available that focus on Amazonian hemerobiid fauna (Penny and Monserrat, 1983).…”

“…As noted in the previous section, many genera classified in the two most diverse families in Brazil, Myrmeleontidae and Chrysopidae, are almost impossible to identify to species, because modern taxonomic treatments are lacking and keys to these groups are unavailable. On the other hand, studies focusing on less diverse neuropteran families should not be avoided, as demonstrated by several recent works that presented some important new records for these families in Brazil, including the description of many new taxa (Machado and Rafael, 2010a;Machado and Krolow, 2016;Martins & Amorim, 2016;Martins et al, 2019;Lara and Perioto, 2021;Assmar et al, 2022;.…”
