Discussion: This is a very small species (body size 3–4 mm) as noted by Spieth (1943), in the species description. It is known from Surinam, Brazil and Venezuela. Peters & Dominguez (2001) detailed variations in size, and coloration. The Venezuelan specimens are larger and the color pattern is more pronounced than the others. H. minuta can be separated from the other species of the genus by the following combination of characters. Imago: 1) general coloration reddish brown, heavily washed with blackish brown; 2) upper portion of male eyes separated basally, meeting medially with well developed eye bridge on inner margin of upper portion; 3) first forceps segment around 2 times length of styliger plate, and curved medially; 4) hind femora yellowish, with wide subbasal and apical dark bands; 5) cerci pale, articulations of basal 3 segments darker.
