E8859788F6C254C896AB1719F8767663.taxon	etymology	Etymology. The specific epithet is the Greek neuter adjective ōiodes (ᾠῶδες, meaning, " oval " or " egg-like "), as a reference to the ovoid pronotum.	en	Xiong, Shurong, Engel, Michael S., Xiao, Lifang, Ren, Dong (2021): New archidermapteran earwigs (Dermaptera) from the Middle Jurassic of Inner Mongolia, China.

5F535F40C707558F958C4FB1C37545B4.taxon	etymology	Etymology. The generic name is a combination of the Greek prefix a - (ᾰ -, alpha privativum designating negation), neuron (νεῦρον, meaning, " nerve "), and derma (δέρμᾰ, genitive dermatos, meaning, " skin " - an allusion to the leathery tegmina and from which the ordinal name is derived, Dermaptera literally meaning, " skin wings "), referencing the absence of tegminal venation, a rare feature among Archidermaptera. The gender of the name is neuter.	en	Xiong, Shurong, Engel, Michael S., Xiao, Lifang, Ren, Dong (2021): New archidermapteran earwigs (Dermaptera) from the Middle Jurassic of Inner Mongolia, China.

B6FC5D807AA5597397B27288C7E4849D.taxon	diagnosis	Diagnosis. The new species can be distinguished from the type species, Sinopalaeodermata neimonggolense (note that the name Sinopalaeodermata is neuter, not feminine, as dermata is the neuter nominative plural of derma; and given that the specific epithet is adjectival it must still agree in gender with the generic name) by the relatively straight apical margin of the penultimate sternum (in S. neimonggolense the penultimate sternum has a concave margin); the roughly reniform pronotum, with the anterior margin concave medially the posterior margin weakly convex, and lateral margins rounded (in S. neimonggolense the pronotum is approximately rectangular, with the anterior margin almost as wide as the posterior margin, and the lateral margins relatively straight and parallel to each other); the tegmina with a more pronounced concave arc marginally at the apex of Rs (in S. neimonggolense the margin is more sloping rather than deeply concave); and M does not extend to near the apex of CuA, with CuP terminating more proximal to CuA (even before the tangent with M) (in S. neimonggolense M terminates more proximally and CuP extends to the apex of CuA). Holotype. A completely preserved female, CNU-DER-NN 2021005 C / P, deposited in the College of Life Sciences, Capital Normal University, Beijing, China.	en	Xiong, Shurong, Engel, Michael S., Xiao, Lifang, Ren, Dong (2021): New archidermapteran earwigs (Dermaptera) from the Middle Jurassic of Inner Mongolia, China.

B6FC5D807AA5597397B27288C7E4849D.taxon	etymology	Etymology. The specific epithet is taken from the Latin adjective concavus (meaning, " concave "), in reference to the more pronounced concave margin to the tegmina relative to the type species.	en	Xiong, Shurong, Engel, Michael S., Xiao, Lifang, Ren, Dong (2021): New archidermapteran earwigs (Dermaptera) from the Middle Jurassic of Inner Mongolia, China.
