Figs 1–4

Diagnosis

Fore wing venation only. 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 Mattéo 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-Dôme.

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.
