Abstract
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.
描述了2015年从缅甸北部上白垩世琥珀中采集到的一个新属和两个新种：Tholimantispa zuoae gen.Tholimantispa zuoae gen. et sp. nov.的特点是具有明显的翼柱、宽阔的肋间隙、分叉的肱脉等，而Mantispidipterella curvis sp.与Mantispidipterella longissima Liu, Lu et Zhang, 2017不同的是，其ScP（subcosta posterior）在与RA（radius anterior）融合处明显弯曲，RP（radius posterior）在ra-rp（RA与RP之间的横脉）处突然成角弯曲，存在AA3（肛前脉的第三分支）。新化石物种丰富了白垩纪双翅目的多样性。
