This new species resembles P. maculosum Zhou, Xu, Jarzembowski & Xiao, 2022 from Burmese amber, but differs in the following characters: head with special convex and small, regular concave; tegmina lack spot, tegmina present five branches between CuPb basal and 1 A, 1 A near distal with two short branches; base of protibiae with a pair of small denticles (in P. maculosum, the head smooth, without convex or concave; tegmina with two regular circular spot, distance between CuPb and 1 A short, CuPb without branch, 1 A distal with four branches; base of protibiae without small denticles). Moreover, this new species maybe resembles P. longirostris (Penalver & Grimaldi, 2010), although the type specimen of the latter is a nymph, can be distinguished by the protibiae without long setae, and base with a pair of small denticles (in P. longirostris, the protibiae with long setae, base without symmetrical denticle).	en	Yu, Huan, Liu, Yu-Wei, Liu, Hao-Yu (2025): Two new species of Elcanidae (Orthoptera: Elcanoidea) from northern Myanmar amber during the late Mesozoic.
