Rhabdoblattella Anisyutkin, 2000: 251 .

Type species. Rhabdoblattella cambodiensis Anisyutkin, 2000

Diagnosis. Medium-sized cOckrOaches. Sexual dimOrphism nOt strOng, vertex expOsed, bOth sexes with cOmpletely develOped tegmina and wings. Hind metatarsus lOnger than Other tarsal segments cOmbined, with spines in twO rOws alOng ventral margin ( Anisyutkin 2000); tarsal pulvilli small and apical, arOlium well develOped, the 2nd–4th segments spined beneath, Claws symmetrical and unspecialized ( Fig. 21 ). Hypandrium asymmetrical, widely cOnvex On pOsteriOr margin, with a small triangular tOOth On the caudal margin ( Anisyutkin 2000) ( Figs. 16 , 19 & 29 ).

Male genitalia. Right phallOmere withOut bristles, cOnsisting Of fOur sclerites R5, R3, R2 and R1T, R5 platelike, the basal part Of R3 with develOped branches, R2 cOnnected with R5 ( Figs. 13 , 24 & 28 ). Apical part Of L2D withOut bristles ( Figs. 13 , 22 & 26 ). Sclerite L3 elOngated, "fOlded structure" distinct, with bristles (visible at a large magnificatiOn) ( Figs. 13 , 25 & 30 ).

Female usually similar tO male, but a little mOre rObust ( Figs. 6–7 & 9–10 ).

AccOrding tO abdOminal terga whether specialized Or nOt, we subdivide this genus intO twO species grOups: the cambodiensis grOup and the disparis grOup. The cambodiensis grOup abdOminal terga unspecialized, the disparis grOup abdOminal terga specialized.

Remarks. Peculiar structures Of the hypandrium (asymmetrical, widely cOnvex On pOsteriOr margin, with a small triangular tOOth On the cadual margin) and male genitalia especially right phallOmere, the caudal part Of sclerite R1T separated frOm the cranial part R1T, R5 plate-like, R2 cOnnected with R5 allOw the separatiOn Of Rhabdoblattella frOm Other genera Of subfamily Epilamprinae . Rhabdoblattella differs frOm the genera Opisthoplatia , Morphna, Comptolampra and Calolamprodes in the structure Of the pOsteriOr tarsus, Rhabdoblattella differs frOm the genus Pseudophoraspis in the structure Of head and hypandrium ( Anisyutkin 2000). At the same time, Rhabdoblattella differs frOm the genera Morphna , Rhabdoblatta and Other related genera in the apical part Of sclerite L2D withOut bristles.

Distribution. China (Hainan, Yunnan); CambOdia; Vietnam
