Shelford 1910: 12; Hanitsch 1915: 73; Asahina 1964: 93; McKittrick 1964: 37; Bey-Bienko 1965: 1642; Princis 1967: 663; Princis 1971: 1157; Mavropulo et al. 2015: 28; Yang et al. 2019: 35.

Heterolampra Kirby, 1903: 276 .

Type species: Epilampra dilatata Brunner von Wattenwyl, 1865 . Synonymized by Princis 1967: 663.

Epilampra Shelford, 1909: 133 . Synonymized by Princis 1967: 663.

Morphnodes Hebard, 1929: 93 .

Type species: Epilampra vasta Walker, 1868 . Synonymized by Princis 1967: 663.

Diagnosis. Body size medium to large, sexual dimorphism insignificant, females slightly larger than males. Vertex slightly exposed. Pronotum subelliptical and the widest part in the middle, middle of posterior margin obtusely produced. Tegmina and wings of male fully developed extending well beyond the end of the abdomen.Anteroventral margin of front femur Type B; the hind metatarsus longer or nearly equal to the remaining segments combined, inner margin with two rows of ventral spines; the pretarsus with large arolia, tarsal claws symmetrical and unspecialized. Supra-anal plate flat, slightly quadrangular, with curved sides. Subgenital plate various in shapes.

Male genitalia. Right phallomere consisting of sclerites R1T, R2, R3, R4 and R5; R1T with caudal part subrectangular, the end of R2 rounded; R3 connected to R 5 in caudal part; R4 present independently. The shape of apical sclerite of L2D and sclerite L3 varies, the apical membrane of L2D typically with chaetae.

Remarks. Based on the similar structure of the right phallomere, there are 7 genera in the Epilamprinae that are similar to Rhabdoblatta : Anisolampra, Acutirhabdoblatta , Brephallus , Cyrtonotula , Morphna , Pseudophoraspis , Opisthoplatia . The genus Rhabdoblatta differs from related genera in the morphology of the pronotum: the pronotum of Rhabdoblatta is almost peach-shaped, while nearly oval with tuberculate surfaces in Anisolampra , subelliptic and broad in Morphna , nearly subrhombic and broad in Brephallus and Pseudophoraspis . The difference between Rhabdoblatta and Cyrtonotula is that tegmina and wings of Rhabdoblatta are extending beyond the abdomen, those of Cyrtonotula don’t exceed the abdomen except for Cyrtonotula longialata Wang & Wang, 2021 . C. longialata can be distinguished from Rhabdoblatta species by having specialized abdominal tergite.

In addition the genus Rhabdoblatta is very similar to Opisthoplatia ( O. ecarinata , O. saussurei ) and Acutirhabdoblatta ( A. densimaculata ) in terms of morphological characters, which is why, the three related mentioned above species were once placed in the genus Rhabdoblatta ( Anisyutkin 2003; Yang et al. 2019). Wang et al. (2023) distinguished the genus Rhabdoblatta from the two genera mentioned above on the basis of right phallomere, tarsal claws and paraprocts.
