Neuroptera of the Amazon Basin. Part 2. Dilaridae

Abstract

Three new species of Nallachius (Neuroptera: Dilaridae) are described from the Amazon Basin.

New records of pleasing lacewings (Neuroptera, Dilaridae) from São Paulo state, Brazil

“…Only N. limai Adams, 1970 is recorded from São Paulo state, Brazil (Martins and Amorim 2015). Herein, we reported the first records of Nallachius adamsi Penny, 1981, N. dicolor Adams, 1970, and N. phantomellus Adams, 1970 from São Paulo state.…”

“…Due in part to their rarity, the biology of this family is poorly documented (Penny 1981, Bowles et al 2015, Liu et al 2017), but the larvae are known live in decayed wood and under barks of dead trees (MacLeod and Spiegler 1961, Penny 1981, Oswald 1998.…”

AbstractThis note extends the geographic range of Nallachius adamsi Penny, 1981, N. dicolor Adams, 1970 and N. phan tomellus Adams, 1970 to São Paulo state, Brazil, based on the examination of specimens obtained in an area of riparian forest (21°36ʹ47ʺ S, 047°49ʹ04ʺ W, ca 532 m above sea level) at the Estação Ecológica de Jataí, in the municipality of Luís Antônio.

First record of Dilaridae (Neuroptera) in the state of Pernambuco, Brazil

“…Nallachius dicolor differs from the other Brazilian Dilaridae species by the combination of the following characters: head pale with unmarked labrum, tubercles on anterior vertex larger than the two posterior ones; forewing with MP2 and CuA not fused and most distal costal cross veins unforked; dorsal lobes of ectoprocts approximated on midline; male genitalia with unforked median lobe (Figures 5-8), lateral projections of mediuncus slender-ligulate apically and gonocoxites lancet-shaped (Figures 4-8); dorsal plate of gonarcus absent (Adams 1970;Penny 1981;Machado and Rafael 2010).…”

“…The natural history and biology of Dilaridae are poorly understood, except for the immature stages of Nallachius americanus (McLachlan, 1881) whose larvae are found under the bark of recently dead trees (Quercus Linnaeus and Liriodendron Linnaeus) (Gurney 1947;MacLeod and Spiegler 1961;Penny 1981;Oswald 1998;Grimaldi and Engel 2005). More data about the species of this family are needed, in order to better understand their biology and biogeography.…”
