Abstract The family Liberiblattinidae is a small but phylogenetically most important group of Blattaria (cockroaches), comprising 17 Mesozoic genera and 20 species. The genus Stavba Vrsanska et Vrsanský in Vrsanský et al. (2019c) of this family consists of two known species. Stavba jarzembowskii sp. nov. is described and figured based on an exceptionally preserved male individual in mid-Cretaceous amber from Myanmar. It is distinguished from the other two species by having more round eyes, a narrower body, broader wings with broader costal area and less crossveins in the radial sector and medial field, and relatively uncurved A veins. Our new find further adds the diversity within this genus and of the cockroaches in 99 Ma tropical forests of Burmese amber.

蟑螂 Stavba jarzembowskii sp. 十一月 (Blattaria: Liberiblattindae) 来自中白垩纪缅甸琥珀

摘要 Liberiblattinidae 科是小蠊科（蟑螂）的一个小但系统发育最重要的类群，包括 17 个中生代属和 20 个物种。Vrsanský et al. 中的 Stavba Vrsanska et Vrsanský 属。(2019c) 该家族由两个已知物种组成。Stavba jarzembowskii sp. 十一月 根据来自缅甸的白垩纪中期琥珀中保存完好的男性个体进行描述和计算。它与其他两个物种的区别在于眼睛更圆，身体更窄，翅膀更宽，肋区更宽，放射区和内侧区域的横静脉较少，A 静脉相对不弯曲。我们的新发现进一步增加了该属和 99 Ma 缅甸琥珀热带森林中蟑螂的多样性。
