Heraty et al. (2011) and Sharkey et al. (2012) defined their Proctotrupoidea s. str. as a monophyletic group, a clade, using analytical methods and including all relevant extant taxa. These analyses strongly supported the monophyly of their new concept of the superfamily Proctotrupoidea. It included seven families: Austroniidae, Heloridae, Pelecinidae, Peradeniidae, Proctotrupidae, Roproniidae and Vanhorniidae. Diapriidae and Monomachidae, formerly considered to be proctotrupoids, were placed (with other taxa) in the sister-group to Proctotrupoidea sensu stricto.

A review of non-aculeate hymenoptera recorded in the world's Cretaceous amber assemblages is provided herein. Recorded are 287 species (265 named) representing 47 families in 17 amber assemblages. The richest in family number is the Burmese (Kachin) amber (35), followed by Canadian (19), Spanish (15), Kheta (12), Raritan (11), Charentese (10), Agapa (9) and Levantine (7) ones; hymenopterans in other ambers are less well documented. In the eight mentioned amber faunas, the share of extinct families decreases from 50/53 to 21 percent in a good correlation with their putative age, therefore suggesting a contiguous character of the studied world fauna. This inference is confirmed by the fact that endemic families are not recorded, with the only but prominent exception of the insular Burmese (Kachin) fauna with its 8 endemic families (23% of known hymenopteran families there). The rate of gradual loss of extinct families in succeeding amber assemblages shows that the main transformation took place during the first half of the Late Cretaceous, and not the Cretaceous-Paleogene boundary. As taxonomic revisions, two species are placed in different families than originally ascribed to, namely, Albiogonalys elongatus Nel, Perrichot & Neraudeau, 2003, is transferred to Praeaulacidae, and Phoriostephanus exilis Engel & Huang, 2017, is transferred from Stephanidae to Roproniidae.

Cell [1M] very narrow, much narrower than cell [2Cu], only 0.2 times as wide as [2Cu]; pterostigma linear, not triangular; base of pterostigma well distal of [1M]; cell [1R1] elongate. Etymology Named after Matt��o Salamone, who helped us to make the photographs and drawing of the type specimen. Type material Holotype FRANCE: MNHN.F. A57266, stored in the collection of Palaeontology (MNHN, Paris). Type stratum and locality FRANCE: Paleocene, spongo-diatomite maar Palaeolake, Menat, Puy-de-D��me. Description A body in rather poor condition with the two fore wings attached. Head 2.3 mm long, 2.8 mm wide, broader than long; head structures hardly visible, except for fragments of the two antennae. Mesosoma 3.9 mm long, 3.6 mm wide; structures hardly visible. Metasoma in poor condition and incomplete but the first segment seems to be narrow tubular, not conical. Fore wing 7.6 mm long, 2.8 mm wide, apparently hyaline except for black pterostigma, 1.7 mm long, 0.23 mm wide, narrow and elongate, situated well distal of cell [1M]; pterostigma and veins covered with small punctuations probably corresponding to the bases of macrotrichiae; cell [1M] quadrangular, 0.7 mm long, 0.1 mm wide, very narrow, much narrower than cell [2Cu]; cell [1R1] very long, 1.9 mm long, 0.4 mm wide; cell [2R1] triangular., Published as part of Garrouste, Romain, Pouillon, Jean-Marc, Nel, Andr�� & Umr, Isyeb -, 2016, The first Cenozoic roproniid wasp from the Paleocene of Menat, France (Hymenoptera: Proctotrupoidea), pp. 1-9 in European Journal of Taxonomy 239 on page 2, DOI: 10.5852/ejt.2016.239, http://zenodo.org/record/3850241

International audience; Paleoropronia salamonei gen. et sp. nov., the first Cenozoic Roproniidae, is described from the Paleocene of Menat (Massif Central, France) on the basis of its fore wing venation. The Roproniidae range between the Mesozoic and the present time. P. salamonei gen. et sp. nov. was perhaps a parasitoid on tenthredinid sawfly larvae, as these insects were present in the wasp fauna from Menat outcrop.

Xiphyropronia tianmushanensis gen. et sp.nov., belonging to the Roproniidae, is described from China.
