PALAEONEURA Waterhouse, 1915

( Figs 210–216 )

Palaeoneura Waterhouse, 1915: 537 . Type species: Palaeoneura interrupta Waterhouse, 1915 , by subsequent designation by Gahan & Fagan, 1923: 103. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Torulus without a small pit next to inner margin ( Fig. 210a ); propleura abutting anterior to prosternum (Fig. 215); fore wing with slight to distinct narrowing beyond apex of venation, the posterior margin of wing thus slightly to distinctly sinuate with a correspondingly slight to distinct lobe ( Fig. 212 ); petiole attached posteriorly to gastral tergum.

Discussion. Palaeoneura belongs to the Polynema group of genera as defined by Triapitsyn & Berezovskiy (2007). In the Afrotropical region this group also includes Acmopolynema , Ganomymar , Mymar , Mymarilla , Polynema and Stephanodes . Palaeoneura is distinguished from P. ( Polynema ) by the propleura abutting medially, sometimes only narrowly, anterior to prosternum whereas in P. ( Polynema ) and P. (Dorypolynema) the propleura do not abut. Palaeoneura is distinguished from Polynema (Doriclytus) by not having pits between the toruli whereas P. (Doriclytus) has pits between the toruli. In both Palaeoneura and Polynema (Doriclytus) the propleura abut anteriorly.

Afrotropical hosts. Hemiptera . The two published records (one extralimital) from Lepidoptera are almost certainly incorrect because Mymaridae are not reliably known to parasitize members of that order.
