The Asian members of the Crematogaster ranavalonae-group are revised and twelve species, including two new species, C. hashimi sp. n. and C. imperfecta sp. n. are recognized. The members are distinguished from the other Asian Crematogaster in having smooth, shiny bodies with short appressed setae on the surface. Crematogaster sikkimensis Forel, 1904 is raised to the species level, and the following new synonyms are established: C. aberrans Forel, 1892 = C. aberrans assmuthi Forel, 1913, syn. n. = C. aberrans inglebyi Forel, 1902, syn. n. = C. soror Forel, 1902, syn. n.; C. ebenina Forel, 1902 = C. ebenina corax Forel, 1902, syn. n. A key to the species based on the worker caste is provided.
