Diagnosis. E. capilliformis belongs to a large group of species with similar cercus morphology (e. g. E. fernandezi Rácenis, 1960 , E. janirae Machado, 2005 , E. lamina Williamson, 1915 , E. venezuelensis , Figs. 6 View FIGURES 4 – 6 , 14 View FIGURES 13 – 15 , 11, 12 View FIGURES 10 – 12 ) in which the cercus dorsal branch is shorter than S10, directed postero-dorsally, approximately rounded in cross section and armed with an apical hook. The ventral branch is approximately rounded or slightly elongate and poorly developed. Species within this group can be separated by epiproct and genital ligula morphology and by the different morphology of the inner-basal structure of cercus. Epipleoneura capilliformis is most similar to E. demarmel s i, and these species can be separated from the others by the unique trilobated distal margin of epiproct ( Figs. 4 View FIGURES 4 – 6 b and 5b), in which the lateral branches are small and triangular accompanying a more or less quadrangular epiproct. In E. demarmelsi the ventral margin of the epiproct is convexly curved ( Fig. 4 View FIGURES 4 – 6 b), while in E. capilliformis it forms a bluntly shaped quadrangular process ( Fig. 5 View FIGURES 4 – 6 b) that may be expanded apically in some specimens. The genital ligula ( Fig. 32 View FIGURES 28 – 47 ) is essentially the same as in E. demarmelsi , E. fernandezi , E. metallica , and E. venezuelensis : segment 3 is medially very narrow, its sides slightly elevated, the apex possesses a wide cleft and the lateral corners are acute; the postero-lateral projection is approximately triangular, directed posteriorly, and has a conspicuous peduncle. Female unknown.

Distribution. Northern and central Brazil, in the States of Amapá, Amazonas, Mato Grosso and Pará (type locality: Irusa Forest, Santarém, Pará). Guyana, Tumatumarí.

Notes. Williamson (1915) includes an illustration of epiproct in posterior view (reproduced in Lencioni 2005), in which the medial lobe is comparatively larger and strongly widened distally, almost with an inverted T shape, not observed in the specimens studied or in the drawings of von Ellenrieder & Garrison (2008).
