A phylogeny of the 22 species currently recognized in the genus Megalagrion, endemic to the Hawaiian Islands, is presented based on an analysis of 23 morphological and ecological characters. After the exclusion ofM. williamsoni, known from only a single male, and inclusion of subspecies within their nominate taxa, a single resolved tree of length 85 was obtained; this tree has a consistency index of 0.56 and a retention index of 0.72. Based on this phylogeny, it appears that the major clades…

Molecular systematics and adaptive radiation of Hawaii's endemic Damselfly genus Megalagrion (Odonata: Coenagrionidae).
Relations among 56 individuals from 20 of the 23 described species using maximum likelihood and Bayesian phylogenetic analysis of mitochondrial and nuclear DNA sequence data are examined to propose a general model for the development of endemic damselfly species on Hawaiian Islands and document five potential cases of hybridization.
Phylogeography and ecology of an endemic radiation of Hawaiian aquatic case-bearing moths (Hyposmocoma: Cosmopterigidae)

The phylogeny suggests that Hyposmocoma is older than any of the current main islands, which may, in part, explain HyposMocoma's remarkable diversity.
Biogeography and systematics of endemic island damselflies: The Nesobasis and Melanesobasis (Odonata: Zygoptera) of Fiji
The evolutionary history of Nesobasis and Melanesobasis is complex and the potential for allopatric speciation within islands, as well as the influence of parasitic endosymbionts, are considered to explain the high rates of speciation in these damselflies.
Speciation and phylogeography of Hawaiian terrestrial arthropods
The Hawaiian archipelago is arguably the world’s finest natural laboratory for the study of evolution and patterns of speciation. Arthropods comprise over 75% of the endemic biota of the Hawaiian
Cladistic analysis, phylogeny and biogeography of the Hawaiian Platynini (Coleoptera: Carabidae)
Intrinsic differentiation in the processes underlying cuticular evolution appears to be more consistent with the observed biogeographic and morphological patterns.
Systematics and biology of the endemic water scavenger beetles of Hawaii (Coleoptera: Hydrophilidae, Hydrophilini)
Phylogenetic analysis based on 55 adult morphological characters affirms that this endemic hydrophilid fauna is a monophyletic clade that incorporates the first well‐supported transformation from an aquatic to terrestrial way of life within any lineage of the subfamily Hydrophilinae.
Insect Radiations on Islands: Biogeographic Pattern and Evolutionary Process in Hawaiian Insects
It is found that, in contrast to earlier views, a substantial fraction of Hawaiian insect clades colonized the archipelago prior to the formation of the current high islands (5.1 Ma), and a positive relationship between clade age and species richness in Hawaiian insects is found, but with a great deal of variance that is likely explained by aspects of ecology and clade-specific factors.
Phylogeographic patterns of Hawaiian Megalagrion damselflies (Odonata: Coenagrionidae) correlate with Pleistocene island boundaries
It is proposed that repeated bottlenecks on Maui Nui caused by sea level change and restricted habitat availability are likely responsible for low genetic diversity there, and an island analogue to northern genetic purity and southern diversity is proposed, whereby islands with little suitable habitat exhibit genetic purity while islands with more exhibit genetic diversity.
Global diversity of dragonflies (Odonata) in freshwater
Diversity is discussed, the biogeography of dragonflies in the different biogeographical regions is summarised and the total number of species and genera per family perBiogeographical region is given.

This study documents the presence of remnant Megalagrion populations in Oahu streams, wetlands and estuaries, and records the elevational distributions of introduced fish in each waterbody surveyed.
