Cyrtonotula Uravov 1939: 459, replacement name for Cyrtonota Hanitsch, 1929; Princis 1967: 662; Mavropulo et al. 2015: 18; Lucañas 2017: 132. New record from China.

Diagnosis.

Medium-sized cockroaches. Both sexes similar. Ocular distance slightly narrower than the distance between antennal sockets, greater than ocellar distance. Pronotum broad, anterior margin curved and posterior margin obtusely produced. Tegmina and wings usually brachypterous, not reaching the abdominal apex (except for macropterous C. longialata sp. nov.), their apices somewhat rounded or approximately truncated. Anteroventral margin of front femur Type B; tarsi moderately long; hind metatarsus slender, distinctly longer or nearly equal to the remaining segments combined, armed with two or less equal rows of spines and large apical pulvilli; succeeding tarsomeres armed only with spines surrounding the large pulvilli; the pretarsus with arolium, claws symmetrical and unspecialized. Supra-anal plate entire, with a median incision. Cerci elongate. Subgenital plate large, nearly symmetrical or somewhat asymmetrical. Styli cylindrical.

Male genitalia. Right phallomere Morphnini - type ( Anisyutkin and Yushkova 2017): consisting of sclerites R1 T, R2 , R3 , R4 , and R5 ; R4 irregular plate-like, separated; R3 connected to R5 . The shape of apical sclerite of L2D irregular and variable. Sclerite L3 hook apically blunt; the folded structure distinct with bristles (visible at high magnification), sclerite L4U present.

Remarks.

Based on the closely similar structure of right phallomere in the epilamprines, four genera have been recorded from China: Morphna Shelford, Pseudophoraspis Kirby, Rhabdoblatta Kirby, and Stictolampra Hanitsch ( Beccaloni 2014; Anisyutkin and Yushkova 2017).

The genus Cyrtonotula differs from Rhabdoblatta , Pseudophoraspis , and Stictolampra principally by its reduction of the tegmina and wings. Additionally, C. longialata sp. nov. is morphologically somewhat similar to some Rhabdoblatta and Stictolampra species but can be distinguished by the presence of glandular specialization on the abdominal tergites, basal portion of sclerite L2D, and the non-punctate pronotum.

The genus Cyrtonotula can be distinguished from Morphna by the structure of hind tarsi: metatarsus distinctly longer or about as long as other segments combined, with relatively numerous tarsal spines (metatarsus slightly shorter or nearly equal to remaining segments combined with larger pulvilli, tarsal spines few or absent).
