ETYMOLOGY. From the Tupi­Guarani indigenous language, relative to or coming from Manaus.

DESCRIPTION. Dimensions. See Table I. Morphology. Ninth sternite ( Fig. 37 ): narrowing gradually toward tip. Tenth tergite ( Fig. 25 ): posterior margin slightly trilobulate; medial lobe rounded, much broader than long. Gonocoxite ( Fig. 37 ): distal half abruptly narrowed, with a stripe of stout hairs all along its laterodorsal margin to apex; other hairs longer and slender. Gonostylus ( Figs. 17 , 37 ): long and narrow, curved, with three strongly sclerotized apical extensions; extensions III and IV closely jointed; extension II more separated. Aedeagal sheath ( Fig. 37 ): without lateral lobes; dorsal crest three­pointed, medial point anterior in relation to the others; ventral branches long, narrowing gradually toward tip. Female cercus: narrowing abruptly toward tip; ventral margin gently curved, not constricted.
