Abstract A second blattoid species, Cercoula brachyptera gen. et sp. nov. is described from Cretaceous amber. It is placed in Blattoidea because of the combination of bivalvate female subgenital plate and type-A forefemoral spination. Its relatively small size, and small, slender, pod-like cerci, suggest that the new species is a stem member of Blattoidea. Cercoula brachyptera is the first fossil of brachypterous cockroach. Since wing reduction might be a response of cockroaches to the arid environment, C. brachyptera might indicate an arid microenvironment or a dry season, or even contribute to the possibility of an arid palaeoclimate of the Myanmar amber locality.

一种短翅类蟑螂（Dictyoptera: Blattaria: Blattoidea）及其与中白垩世缅甸琥珀地区古环境的潜在相关性

摘要 第二种小蠊属，Cercoula brachyptera gen。等 sp. 十一月 描述自白垩纪琥珀。它被放置在 Blattoidea 中，因为它结合了双瓣的女性生殖器下板和 A 型前股旋转。其相对较小的体型和细长的豆荚状尾尾表明这个新物种是蠹总科的一个茎成员。Cercoula brachyptera 是短翅类蟑螂的第一个化石。由于翅膀减少可能是蟑螂对干旱环境的反应，C. brachyptera 可能表明干旱微环境或旱季，甚至有助于缅甸琥珀地区干旱古气候的可能性。
