Order DERMAPTERA, earwigs The earliest earwigs previously known are from the Upper Jurassic of the The two specimens from Dorset differ from Recent Dermaptera mainly in the ornamentation of the tegmina, which in most Recent species is smooth. No veins could be seen in the forewing (tegmina), which is shorter than the abdomen, although there may have been a trace of a subcostal vein. Suborder ARCHIDERMAPTERA Diagnosis. Tegmina reaching well down abdomen. Tarsi 4-5 segmented. Remarks. Only one family and genus, from the Upper Jurassic of Kazakhstan, are currently known in this suborder. Family PROTODIPLATIDAE Martynov, 1925b Diagnosis. As suborder. The new genus described below is provisionally-placed in this family. Western Europe, Jurassic. Genus BREVICULA nov. Type species. Brevicula gradus sp. nov. Lower Lias, Diagnosis. Tegmina strongly punctate, reaching at least to second abdominal segment. Coxae short, rounded. Name. 'A little thing'..
