NEW RECORDS OF MARTAREGA, GRAPTOCORIXA, AND ABEDUS (HETEROPTERA: NOTONECTIDAE, CORIXIDAE, BELOSTOMATIDAE) FROM NORTHWESTERN MEXICO AND ARIZONA, INCLUDING THE FIRST RECORD OF GRAPTOCORIXAEMBURYI IN THE UNITED STATES

摘要

While distributions of aquatic insects are fairly well known in the southwestern United States, relatively few surveys have been conducted in northwestern Mexico. We report new collections of species of aquatic Heteroptera in the region, which extendthe known range of several species by hundreds of kilometers, including the first record of Graptocorixa emburyi in the United States, and help show that disjunct distributions of other species are more continuous than previously thought.
