The polytene chromosomes of 512 larvae of the Simulium nobile species group collected from 16 stream sites in northern, central and southern Thailand were examined. Band-by- band comparisons relative to the established standard chromosome map for the subgenus Simulium distinguished the 2 species of this group, S. nobile and S. nodosum. The differences are(More)
To investigate patterns of geographical and ecological separation among morphologically similar, closely related species of black flies, we integrated ecological, geographical, and phylogenetic information, based on multiple gene sequences, for 12 species in the subgenus Gomphostilbia in Thailand. Molecular characters supported the monophyly of the Simulium(More)
