Discussion. Miroculis (Miroculis) marauiae was described originally from Northern Brazil (Amazonas state). The imagos of this species can be characterized by: 1) Upper portion of eyes on narrow, dorsally directed stalks, with 8 to 9 facets in longest row; 2) fore and hind wings without maculae around cross-veins; and 3) length of penes 0.8–1.1 times length of segment I of forceps. In the nymph, the abdominal gills are small and slender, with posterolateral lobes from medium-sized to reduced. In this study imagos and nymphs of this species were collected at elevations from 900 up to 1355 m.

Distribution. Brazil and Venezuela (new country record).

Ecology. Imagos and nymphs were collected in water currents with acidic waters (pH = 5) that ranged from small streams (12 m wide) to medium rivers (30 m wide). They also varied in their riparian vegetation (from partially shaded to non-shaded) and bottom (from bed-rock bottom to gravel-bottom rivers). Collections corresponded to dry (March 2006) and rainy season (November 2005, March 2006 and June 2007).
