M. K. Tan & H. Yeo. Generic status. The species is considered a member of Cercoteratura by the presence of these characters: male tenth abdominal tergite with posteromedian lobe (which is rather diverse in shape and width among congeners), male cerci strongly curved upwards and situated very close to each other in rest position (sensu Gorochov, 2019 ). Comparison with congeners and diagnosis. Cercoteratura mirabilis comb. nov. differs from all known congeners by (1) male tenth abdominal tergite with posterior margin deeply notched in the middle, in the middle produced into a flat rectangular lobe; apex of this rectangular lobe with two lateral stout processes. (2) Basal part of male cercus laterally produced into a triangular ventral lobe pointing externally and with a small flattened ventral internal lobe; remaining of cercus curved dorsad, then anteriorly; apex of cercus somewhat truncated, sinuate into a flattened apical lobe pointing internally when viewed posteriorly. (3) Male genitalia with elongated sclerotized epiphallus; lateral margin with a lobe at the middle and ventro-posterior end; lateral lobes produced into acute spinelike processes ( Tan & Wahab, 2018b ). Cercoteratura mirabilis comb. nov. is most similar to C. spinicauda and C. variegata by the black patterns across the body (whereas C.? abbreviata and C. modesta are more unicolourous) but the males differs mainly by shape of tenth abdominal tergite, shape of cercus and genitalia.
