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).
