Habitat preferences among species of the plethodontid subfamily Desmognathinae are varied, ranging from fully aquatic (Desmognathus marmoratus) and semiaquatic stream-dwelling species (Desmognathus quadramaculatus) to inhabitants of the forest floor (Desmognathus wrighti, Desmognathus aeneus; Hairston, 1984).

We considered portions of that fauna, in particular groups associated with aquatic habitats, in earlier papers [Ephemeroptera and Odonata (Lago and Testa, 1987); Embiidina, Dermaptera, Isoptera, and Orthoptera (Lago, et al., 1988); aquatic and semiaquatic Hemiptera and Coleoptera (Lago and Testa, 1989); and biting flies (Lago and Testa, 1990)].
In addition to the diversity of its forest systems, the chaco contains rich and varied communities dominated by a herbaceous layer: floodable savannahs, grasslands, an extraordinary variety of aquatic and semiaquatic environments in the eastern part, broad saline or alkaline grasslands on its limit with the pampa, and--in both the many eastern valleys and in some depressions in the western Chaco--large palm groves of the carandai palm (Copernicia australis).
