Abstract

Conostigmus Dahlbom, 1858 (Hymenoptera: Megaspilidae) is reported for the first time from Brazil. Here, we provide a diagnosis of Conostigmus binasutus Dessart & Cancemi, 1986 and the description and illustration of the female, previously unknown. The analyzed material was collected utilizing Malaise traps, in Manaus, Amazon, Brazil and deposited at the Invertebrate collection of INPA (Instituto Nacional de Pesquisas da Amazônia) of Manaus. A identification key and distribution map to the Neotropical species of Conostigmus is provided.

Highlights

Megaspilidae Ashmead, 1893 is recognized and separated from other families of Hymenoptera for presenting fore wing usually with large stigma and mesoscutum commonly with three longitudinal furrows or rarely reduced to a narrow sclerite (Goulet and Huber, 1993)
Little data are available about the biology of Megaspilidae

Summary

Introduction

Megaspilidae Ashmead, 1893 is recognized and separated from other families of Hymenoptera for presenting fore wing usually with large stigma and mesoscutum commonly with three longitudinal furrows or rarely reduced to a narrow sclerite (Goulet and Huber, 1993). Little data are available about the biology of Megaspilidae. Are generally ectoparasitoids which attacking, primarily on Diptera, Neuroptera, Coleoptera, Mecoptera and as hyperparasitoids of Hymenoptera (Dessart, 2006). Megaspilidae is a cosmopolitan family, includes 308 valid species in 12 genera (HOL, 2018), classified in two subfamilies, Lagynodinae Masner & Dessart, 1967 and Megaspilinae Ashmead, 1893 (Dessart, 2006). The South American fauna is little known. The largest subfamily is Megaspilinae, and for Brazilian fauna, there are two genera known: Dendrocerus Ratzeburg, 1852 recorded with five species, in many regions of Brazil; Braz. Biol., 2020 , vol 80, no. 2 pp.373376 and Trichosteresis Förster, 1856 with one species, in São Paulo state (Dessart and Cancemi, 1986; Dessart, 1987; Dessart, 1996; Tavares, 1996; Macedo and Kawada, 2013; Pezzini et al, 2014; Iemma et al, 2016; Pezzini and Köhler, 2017; Margaría, 2018)
