Several species within the genus <i>Blattella</i> Caudell, 1903 and its closely related genera (<i>Episymploce</i> Bey-Bienko, 1950; <i>Symploce</i> Hebard, 1916; and <i>Jacobsonina</i> Hebard, 1929) exhibit external morphological traits similar to those of <i>B. germanica</i>. By integrating morphological identification and molecular analyses, one new species was identified: <i>Jacobsonina uncata</i> Cai, Yao & Che, <b>sp. nov.</b> Additionally, <i>Blattella asahinai</i> Mizukubo, 1981 was downgraded to a subspecies of <i>B. germanica</i>.
