Neuroptera Hemerobiidae new genus new species Cretaceous Myanmar


A new genus and species of the lacewing family Hemerobiidae, Cretoneuronema jarzembowskii gen. et sp. nov., is described from the mid-Cretaceous Kachin amber in northern Myanmar. This new genus has a definite hemerobiid affinity and is characterized by the distally fused ScP and RA in both fore- and hind wing, the presence of forewing RP and MA (= ORB1 and ORB2) separately diverging from R near wing base and closely spaced with each other, the forewing MA with anteriorly directed branches, the deeply forked forewing CuP, and the completely developed hind wing CuP. The new genus resembles some extinct brown lacewing genera, such as Promegalomus Panfilov, 1980, Cretomerobius Ponomarenko, 1992, and Proneuronema Makarkin, Wedmann & Weiterschan, 2016, from the Late Jurassic to Eocene, and represents the second Kachin amber genus of Hemerobiidae, a family that appears to be very rare from this deposit.
