Taxonomic notes.

The limited information provided by Del Guercio (1899) does not allow designation of the two species of Nemeritis  to any of the parasitoids associated to EGVM. Though Leonardi (1925) included the work of Del Guercio in his bibliography, he did not quote these species, which are not mentioned by any other author.

The species of Nemeritis  have been divided by Horstmann (1975) in four groups: caudatula- and elegans  -group, which parasitizes Raphidioptera  , macrocentra-group which parasitizes Coleoptera  ( Cleridae  , Malachiidae  ) and Lepidoptera  and lissonotoides-group for which no host records are available ( Horstmann 1994). Even though most of the species seem to attack concealed hosts under the bark or in bark crevices ( Horstmann 1975), few species of the macrocentra-group have been recorded on moth species of economic importance, like the Mediterranean flour moth ( Ephestia kuehniella  Zeller, 1879), the European grain moth ( Nemapogon granella  (Linnaeus, 1758)) or the strawberry fruitworm ( Cnephasia longana  (Haworth, 1811)) ( Horstmann 1994; Yu et al. 2012).

In the past, the genus Nemeritis  included species of other campoplegine genera like Campoplex  , Cymodusa  or Venturia  ( Thomson 1887, Schmiedeknecht 1909). It is possible that the two species cited as Nemeritis  sp. by Del Guercio (1899) are actually Venturia canescens  (Gravenhorst, 1829). Schmiedeknecht, who identified ichneumonids obtained by Del Guercio (1899, page 156), refers to Venturia canescens  as Nemeritis canescens  in his fundamental work on European ichneumonids ( Schmiedeknecht 1909, page 1688). At least the general habitus and wing venation in the picture of the second species ( Del Guercio 1899, page 156) fit with the general aspect of V. canescens  .
