• Genetic analyses were carried out using wild type stocks presumed to carry genetic components which strongly enhanced crossing over in males of Drosophila ananassae. A new enhancer (symbolized En(2)-cc) is located in the vicinity of the e locus residing in 2L of the E22 stock from India. This result suggests the possibility that the new enhancer and the En(2)-cm previously mapped to the right of the e locus in the L8 stock from Sri Lanka are allelic, although mapping lacks precision. Another new enhancer (symbolized En(2)- hn) discovered in the HW stock from Hawaii is identified to be situated in a new locus in the vicinity of the Arc locus in the proximal region of 2L. The En(2)-hn is separable from the En(2)-cm by recombination.
