Comparison. Differs from Archaeodrepanicus, Sinomenomantispa, Karataumantispa, Longicollum gen. nov. in having a stout forecoxa, trochanter, and an oval shaped forefemur. Forefemur not as enlarged and club-like as Clavifemora . Ovalofemora gen. nov. is further separated from Archaeodrepanicus, Sinomesomantispa, and Clavifemora by the presence of large hooked prostrate setae, and the combined length of the foretibia and foretarsus being greater than the forefemur. Ovalofemora gen. nov. can be further separated from Karataumantispa by M forking more distally, possessing a simple branched MP. It differs from Mesomantispa in possessing a strongly pectinate CuA, an absence of crossveins in the cubital and anal area, and a less dense venation pattern. It differs from Longicollum gen. nov. in possessing a shorter pronotum, 1.4x longer than wide [ Longicollum gen. nov.: 2.8x longer than wide].
