          Abstract

          Foi encontrada uma riqueza de 15 espécies de pseudoscorpiões, de 12 gêneros e 5 famílias (Chthoniidae, Geogarypidae, Olpiidae, Atemnidae e Chernetidae), habitando diferentes plantas da vegetação do sub-bosque, em floresta primária de terra firme, no alto rio Urucu, Coari, Amazonas, no período de 1991 a 1996. As plantas foram examinadas pelo método de "bateção". Apolpium aff. vastum foi à espécie mais freqüente e abundante sobre as plantas. Dentre os tipos de plantas avaliados, as maiores diversidades de espécies de pseudoscorpiões foram registradas nas pequenas palmeiras, tanto com fronde junto ao chão, como elevada acima do chão. A análise da composição das espécies que ocorreram sobre os diferentes tipos de plantas avaliadas foi realizada pelo "modo-Q", tendo como base a matriz de coeficientes de similaridade de "Jaccard", o que demonstrou maior similaridade entre a fauna das palmeiras e outras plantas que acumulam detritos acima do chão, entre as bromélias e entre aráceas de chão e outras plantas que acumulam detritos junto ao chão.

          Translated abstract

          A richness of 15 pseudoscorpion species, 12 genera belonging to 5 families (Chthoniidae, Geogarypidae, Olpiidae, Atemnidae and Chernetidae) were found in the undergrowth vegetation of the dryland forest, at the upper Urucu river, Coari, Amazonas, from 1991 to 1996, and was collected by the "beating tray" method. Apolpium aff. vastum was the most frequent and abundant species in the undergrowth forest vegetation. Among the various types of plants examined, the majority of the pseudoscorpions occurred in small palms (in the ground-trenched palms as much as the erect stemmed palms). To appraise the specie's composition of these arachnids found in the different kinds of plants, the Q-mode analysis was used based on Jaccard's similarity coefficients. The coefficients that showed the greatest similarity were between the fauna of the palms and other plants that accumulate litter on top of the ground, and between the Bromeliacea and Aracea of the floor and other plants that use the litter of the ground.
