New genus and species of the families Olidae and Corydiidae (Corydioidea, Blattodea) from mid-Cretaceous Kachin amber
Abstrakt
Olidae VRŠANSKÝ et WANG, 2017 is an obscure, extinct cockroach family with only two representatives documented from Kachin amber. A new member of this unique family, Olenablatta vrsanskyi gen. et sp. nov., is described here from the same amber together with a corydiid Nodosigalea simplivena sp. nov.
Genera Spinka VRŠANSKÝ, ŠMÍDOVÁ et BARNA in VRŠANSKÝ et al. (2019a) and Bimodala ŠMÍDOVÁ in VRŠANSKÝ et al. (2019a) are transferred from the family Blattidae LATREILLE, 1810 into Corydioidea SAUSSURE, 1864. Bimodala ohmkuhnlei ŠMÍDOVÁ in VRŠANSKÝ et al. (2019a) is redescribed on the basis of a new complete specimen including previously unknown head structures.
Comparative material allowed the formal transfer of Olidae and numerous other taxa into the superfamily Corydioidea.
