Abstract:Hawaiʻi is a diverse ecological hotspot of biodiversity, home to many adaptive radiations including a clade of damselflies which encompass the full known range of damselfly breeding habitats and encompass a range of habitat specificity but are of increasing conservation concern. I tested the effects that habitat specificity might have on gene flow and population differentiation between a relative generalist Megalagrion vagabundum and a relative specialist Megalagrion nigrohamatum nigrolineatum. Mitochondrial genes indicate that there is significant differentiation at a fine-scale in M. vagabundum and suggests that differentiation may be even stronger in M. n. nigrolineatum. These data are further discussed with respect to genetic variation within these two species and possible barriers to dispersal and the ecology and conservation of these two Megalagrion species.
