Description. Male. Body length about 1.35 mm (N=02). Wing length about 1.62 mm (N=02). Terminalia ( Fig. 7 ). Gonocoxite longer than wide, with great indentation at base. Gonostylus long and thin, with apical tooth. Cerci as long as hypoproct. Hypoproct microtrichia-covered, with spiniform microtrichia ventrobasally, with two lateral, cylindrical lobes covered with spiniform microtrichia throughout, continuing as a dorsoventrally flattened, apically bilobed lamella, with deep and narrow emargination and a prominent seta on each lobe. Hypoproct about three-quarters length of aedeagus. Mediobasal lobe of gonocoxite entire, elongated, cylindrical, with dorsoventrally flattened apex bearing few setae, microtrichose throughout; a little shorter than aedis neutereagus. Aedeagus broad at base, tapering at apex and with rounded tip; longer than gonocoxite.

Etymology. The specific name “ pantaneirum ” is given as a reference to the core area of the biome Pantanal, where the type species was sampled.
