A new species of Neurocordulia (Odonata : Anisoptera : Corduliidae) from eastern North America

The new species Neurocordulia michaeli sp.nov. from New Brunswick and Maine differs from other northeastern species in the genus in its short mesotibial keel and from all congeners in the great width of its abdomen. The species is obligate crepuscular and can be locally abundant at its riverine habitat. Larvae of the species have the lowest dorsal spines in the genus and cling to the underside of rocks in rapids.
