PALAEONEURA Waterhouse, 1915 View in CoL

( Figs 236–246 View FIGURES 236–239 View FIGURES 240–246 )

Palaeoneura Waterhouse, 1915: 537 View in CoL . Type species: Palaeoneura interrupta Waterhouse, 1919 View in CoL , by subsequent designation by Gahan & Fagan, 1923: 103. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Face without subantennal sulcus ventral to each torulus and without a small pit medially next to each torulus ( Fig. 240 View FIGURES 240–246 ); toruli separated by at least their own height from transverse trabecula; propleura narrowly abutting each other anterior to prosternum ( Figs 241, 243 View FIGURES 240–246 ); fore wing slight to distinct narrowing beyond apex of venation, the posterior margin of wing thus slightly to distinctly lobed ( Fig. 239 View FIGURES 236–239 ); petiole attached posteriorly to gs 1 ( Fig. 237 View FIGURES 236–239 ).

Remarks. Palaeoneura belongs to the Polynema group of genera. Palaeoneura is identified first by elimination from most of the other genera in the group, then by features used to distinguish it from specimens of two of the three subgenera of Polynema that occur in the Neotropical region. Palaeoneura is distinguished from P. ( Polynema ) by the propleura abutting medially, sometimes only narrowly, anterior to prosternum whereas in P. ( Polynema ) the propleura are separate from each other anteriorly. Palaeoneura is distinguished from Polynema (Doriclytus Foerster) in not having pits between the toruli whereas P. (Doriclytus) has pits between the toruli. Palaeoneura is distinguished from Polynema (Dorypolynema Hayat & Anis) by the ovipositor not exserted beyond the apex of the gaster.

Neotropical hosts. Hemiptera : Cicadellidae .
