Jurassipanorpa impunctata gen. et sp. n. and Jurassipanorpa sticta sp. n. described in this study are the earliest fossil panorpids in the world hitherto. The holotypes of these two new species of Jurassipanorpa gen. n. are well-preserved, including both wings and most of the body. New information from these two new species enhances our understanding of the morphological characters of Panorpidae and diversity of Mecoptera during the late Middle Jurassic.

These two new species are the earliest fossil records of Panorpidae. The new genus is erected based on a combination of forewing characters: both R1 and Rs1 with two branches, 1A reaching posterior margin of wing distad of the forking of Rs from R1, and no crossveins or only one crossvein between veins of 1A and 2A. In all four specimens, long and robust setae ranging from 0.09 to 0.38 mm in length and pointing anteriorly, are present on anal veins of forewings. The function of these setae is enigmatic.

We assigned this genus to Panorpidae mainly based on the following characters: (1) head capsule with prolonged downward mouthparts; (2) slender wings and forewing slightly larger than hind wing with similar veins; (3) forewing Rs with five branches; (4) forewing M with four branches; (5) forewing Cu1 not fused with M basally, one crossvein between M4 and Cu1; and (6) hind wing Rs with five and M with four branches as those of forewing.
