New findings of dipteromantispids (Insecta: Neuroptera) from Upper Cretaceous Myanmar amber.

A new genus and two new species, Tholimantispa zuoae gen. et sp. nov. and Mantispidipterella curvis sp. nov. are described from the Upper Cretaceous of northern Myanmar amber collected in 2015. Tholimantispa zuoae gen. et sp. nov. is characterized by its distinct pterostigma, broad costal space, bifurcate humeral veinlets, and so forth, and Mantispidipterella curvis sp. nov. is different from Mantispidipterella longissima Liu, Lu et Zhang, 2017 in its ScP (subcosta posterior) distinctly curved at fusing point with RA (radius anterior), RP (radius posterior) abruptly and angularly curved at ra-rp (crossvein between RA and RP), AA3 (third branches of the anterior anal vein) present. The new fossil species enrich the diversity of Dipteromantispidae in the Cretaceous.
