“…Some of their hosts are known to cause damage on orchid roots and shiitake crops, which might have their populations reduced by the action of these parasitoids Mukai and Kitajima 2019). Despite recent efforts studying the diversity of this subfamily in the Neotropical region (Humala 2010(Humala , 2014(Humala , 2017(Humala , 2019Veijalainen et al 2012Veijalainen et al , 2014aZwakhals and Diller 2015;Humala and Ruiz-Cancino 2017;Camargo et al 2020), a large taxonomic gap regarding this fauna remains, mainly as a result of a high diversity combined with small body size (Quicke 2012).…”

“…Currently, the approximately 500 described Orthocentrinae species are distributed among 29 genera (Villemant et al 2016;Yu et al 2016;Klopfstein et al 2019) that are separated into two groups: the Orthocentrus genus group and the Helictes genus group (Broad et al 2018). In the Neotropical region, 109 species in 17 genera are known; of these, only seven species in four genera have been recorded in Brazil (Veijalainen et al 2012;Yu et al 2016;Humala 2017Humala , 2019Humala and Ruiz-Cancino 2017;Camargo et al 2020). Here, we present the first comprehensive survey of the Orthocentrinae in Brazil that focuses on high-elevation sites (for Brazilian standards), characterising the fauna at the genus level and estimating its diversity along an elevational gradient based on molecular operational taxonomic units inferred by DNA barcoding analysis.…”

The Orthocentrinae is one of the least-studied groups within Ichneumonidae and possibly a major component of the tropical fauna, encompassing a rich but still obscure diversity. In this first attempt to uncover these biota in Brazil, we surveyed a restricted area within mountain chains in the southeastern region immersed in the Atlantic tropical forest, using several sampling methods along an elevational gradient. Using integrative taxonomy, we found a richness eight times higher than the current number of species known in Brazil, including 13 genera, of which 10 are new to the country. The 127 molecular taxonomic units found represent an increase of at least 50% in species for the Neotropical fauna, confirming the immense gap in taxonomic knowledge of this group in the Neotropics. Analyses of elevational gradient patterns of distribution indicated an increase in species elevational ranges with increasing elevation, supporting Rapoport’s rule. A key including all 14 genera occurring in Brazil is proposed, aiming to facilitate future taxonomic reviews and encourage research on this group. Orthocentrinae is a major component of the fauna and likely to be more diverse in wet lowland tropical forests; however, taxonomic and faunistic studies in tropical areas, including dry forests and savannahs, are needed.
