Bristle counts of the sixth sternites of males were performed for four related species of Drosophila auraria complex. Drosophila auraria male has about 14 bristles. Drosophila triauraria and D, quadraria have about 13 and 12 bristles, respectively. Drosophila biauraria has generally none. The difference found in the mean bristle counts was statistically significant between species. Wild type strains of D. auraria and D, biauraria were hybridized and males of the F1 and the backcrossed progenies were compared as concerned with their sternite bristles. It was found that the X chromosome and the autosome (s) were both responsible for the manifestation of the sternite bristles.
