Paracloeodes lilliputian Kluge 1991:134 (female imago and nymph).

Holotype. Female imago, Province Guantánamo, Río Duaba (Baracoa), 15-III-1989, N. Kluge.

Kluge (1991) described the nymph and female imago of this species from the Río Duaba. In the nymphs, the tarsal claws have two rows of tiny denticles basally and the apical setae of the paraglossae are arranged in a row. The abdominal terga have median maculae contrasting with the otherwise pale coloration of the margins, and the contrast between the darker tergum and the small white lateral maculae on tergum 9 is an excellent diagnostic character for the species. The head has a longitudinal keel between the antennae. Imagos of both sexes of Paracloeodes lack hind wings; males have large, well developed eyes and apparently three-segmented forceps. Unfortunately, the male imagos of P. lilliputian are unknown.

Ecology. In general, nymphs of the genus Paracloeodes live in deep rocky areas of large rivers and then migrate toward the shore as they reach maturity; they also prefer sandy areas and strong current ( Edmunds et al. 1976). Kluge (1991) described the species from the Río Duaba in Baracoa, Guantánamo Province, but it was not collected again until Benítez (2007) found nymphs in the Rió Yáquimo, Amancio, in Las Tunas. In the Yáquimo, nymphs were collected in both rapids and pools, although most were collected in rapids. However, recent observations have found that it is also common in leaf packs.

Geographic distribution. The species has been recorded from the Central-East and Eastern regions of Cuba ( Kluge 1991; Benítez 2007) ( Fig. 6 ). In this work, we also found two nymphs from the Río Mayarí (3-II-2001, col. Aldana and Fonseca), Eastern Region.
