Type species: Fissilobulata longiloba sp. nov.

Generic characters. Body stout. Fastigium verticis conical, apex rounded, with longitudinal sulcus on dorsal surface.Apical segments of maxillary palpi approximately equated in length with subapical segments, apices faintly swollen. Pronotum short, lateral lobes longer than deep, humeral sinus absent. Tegmina shorter, slightly surpassing the posterior margin of pronotum; hind wings absent. All femora without spine on ventral surfaces; fore tibial tympana open on both sides; genicular lobes of hind femora with apices rounded, tibiae apically with a pair of dorsal spurs and 2 pairs of ventral spurs. Lateral margins of male ninth abdominal tergite elongated backward and curved ventrally, tenth abdominal tergite narrow without any process; cerci simple, only reaching the basal area of ninth abdominal tergite; genitalia sclerotized, exposed; posterior margin of male subgenital plate with a large median lobe and styli. Female subgenital plate posteriorly concave, the lateral lobes triangular; ovipositor stout, slightly upcurved, apices acute.

Discussion. The new genus is very similar to Acosmetides Chang, Wang & Shi, 2021 , Macrocosmetura Chang, Wang & Shi, 2021 , Neocyrtopsides Chang, Wang & Shi, 2021 , Neocyrtopsis Liu & Zhang, 2007 and Sinocosmetura Guo, Shi & Chang, 2021 in appearance, especially the first three genera. To better understand the newly established genus, we provide species morphological illustrations of the five known genera mentioned above. The new genus can be distinguished by: male ninth abdominal tergite elongated backwards forming a pair of long processes contacting each other, genitalia sclerotized, subgenital plate with a median lobe; female subgenital plate with a median concavity on posterior margin.

Etymology. The name of the new genus refers to the long process of male ninth abdominal tergite.
