Popis: Multivariate morphometric analyses were performed on workers of Apis koschevnikovi from throughout their distribution in Malaysia, Borneo and Indonesia. Principal component analysis showed one morphocluster comprising bees from Kalimantan Indonesia, Sarawak, Sabah and the Malay Peninsula. The population is more homogeneous than A. cerana over the same geographical area, as seen from the average coefficient of variation in 12 characters in A. koschevnikovi (1.8%) compared to those same characters in A. cerana (4.3%). A. koschevnikovi is delimited to the tropical evergreen forest regions of Sumatera, Borneo, and the Malay Peninsula (Fig. 1). The altitudinal distributions show that A. koschevnikovi extends from sea level to about 1600 m. This significantly differs from A. nuluensis but not A. cerana. It appears that the range of A. koschevnikovi is diminishing because it is now either poorly represented or absent in several areas where it has been previously recorded.
