From the reviews: "This book, already issued in 2001, is the first in a series of identification keys of South American insects limited to continental South America and the offshore islands found in a variety of 'aquatic habitats' (in, on, near water etc) treating the Collembola. The series is obviously directed to the practician. ... we have to thank the author for this compilation. Its usefulness has to be proved by practice."
