A new species of Hemerobiidae (Neuroptera) from the late Eocene Rovno amber

Proneuronema damzeni sp. nov. (Neuroptera: Hemerobiidae) is described from late Eocene Ukrainian Rovno amber. It differs from the two other species of this Eocene genus by a combination of the following character states: forewing larger (7.3 mm long in the new species; 6.3-6.9 mm in P. minor Makarkin et al., 2016; 5.9 mm in P. sydorchukae Makarkin & Perkovsky, 2020) and broader (length to width ratio is 2.14 in the new species; 2.46 in P. sydorchukae; 2.17-2.30 in P. minor), and different forewing maculation (one spot at the third ('inner') gradate series in the new species; two in P. sydorchukae; none in P. minor). The Fur Formation Megalomus densistriatus Henriksen, 1922 and the Baltic amber Proneuronema gradatum Makarkin et al., 2016 are preliminary assigned to Archibaldia Makarkin, 2023 as Archibaldia densistriata, comb. nov. and A. gradata, comb. nov., respectively. The species composition and distribution of Proneuronema and Archibaldia are briefly discussed.
