The mechanism of sympatric host race formation in the true fruit flies (,)ts and animals has existed from the time Benjamin Walsh published his provocative paper on sympatric host race formation in phytophagous insects in 1864. Use of the term host race itself has created problems as it has been applied to taxons ranging from sibling species to biotypes. I will limit it t

Speciation in the Australian Morabine Grasshoppers — taxonomy and ecology tropics and subtropics of the Old and New Worlds. Of some 240 species of Morabinae known to exist, only 35 or 36 have been named and described. Representatives of the undescribed species are preserved in the Australian National Insect Collection in Canberra, under code numbers which have been exten

Patterns of speciation in Hawaiian , inferred from ancient chromosomal polymorphism especially Diptera. Study of the allelic frequencies of the components of these polymorphisms, together with their geographical distributions, have indicated that some of them must have existed in the balanced state in populations for a considerable number of generations. How long this has been in

Mating behavior and evolution of the Hawaiian ,ist of such features includes (1) the large size of many of the species, (2) striking pigmenta-tion patterns of numerous species, and especially the prevalence of patterned wings, (3) numerous diverse, often bizarre sexual dimorphic characters, (4) a high level of agonistic behavior exhibited both i

Phylogenetic relationships of Hawaiian Drosophilidae based on morphologygement of species into some scheme of classification that can be taken as indicating their degree of genetic relationships/ He discussed in detail the methods in analyzing and selecting characters which are important in showing phylogenetic relationships between species. It is clear that Sturtevant’
