Abstract

The new species Neurocordulia michaelisp.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.

Résumé

Neurocordulia michaelisp.nov. est une espèce crépusculaire qui peut s’avérer abondante localement dans les sections rapides des rivières du Maine et du Nouveau-Brunswick. Les larves se retrouvent agrippées aux parois inférieures des pierres. Les adultes se distinguent des autres espèces de ce genre par une plus courte carène mésotibiale ainsi que par un abdomen beaucoup plus large. Les épines dorsales, chez la larve, sont plus courtes que celles rencontrées chez la larve des autres espèces.
