Abstract
Sympatric occurrence of homozygotes for two electromorphs controlled by a locus for octanol dehydrogenase, and the absence of heterozygotes, at two localities, indicates two isomorphic species within the taxon Anopheles minimus Theobald in Thailand. This view is supported by significant, relative deficiences of heterozygotes at other electromorhpic loci. Gene frequency data are reported for seven electromorphic loci in An. minimus sensu lato from eleven localities: one of the newly recognized species predominated in all but one locality and the second was confined to two localities. This species pair of An. minimus s.l. was clearly distinguished from An. aconitus Donitz, An. pampanai Buttiker and Beales and An. varuna lyengar, three species closely related to An. minmus s.l. in the series Myzomyia of Anopheles subgenus Cellia.
