Abstract

Three new species of isotomid springtails are described from the Lake Champlain Basin (Vermont and New York, USA), Lake Willoughby and Greater Averril Pond in Vermont. Subisotoma joycei sp. n. and Scutisotoma champi sp. n. were collected in sandy beaches whereas Ballistura rossi sp. n. was found only in a constructed wetland built and managed by the University of Vermont. Scutisotoma champi sp. n. was found in Lakes Champlain and Willoughby, and Greater Averril Pond and is probably present in most lakes and large ponds in the area. Subisotoma joycei sp. n. was found only along the southern and eastern coast of South Hero, and the mainland coast facing eastern South Hero. Ballistura alpa Christiansen & Bellinger is redescribed and transferred to the genus Pachyotoma based on the absence of tibiotarsal seta B4/B5, the presence of secondary cuticular granules, 4 prelabral setae, a full complement of guard setae on labial papilla E and ina bifurcate outer maxillary lobe with 4 sublobal setae.
