( Figs. 3 View FIGURES 1 – 3 , 26– 35 View FIGURES 26 – 35 )

Nymph ( Fig. 3 View FIGURES 1 – 3 ). Length: body, 4.1–4.2 mm; cerci, 1.4–1.5 mm; terminal filament, 1.3–1.4 mm. Antennae partially broken. Head pale yellow, longer than wide, compound eyes pale yellow. Antennae pale yellow. Mouthparts ( Figs. 26–31 View FIGURES 26 – 35 ): labrum ( Fig. 26 View FIGURES 26 – 35 a) with one subapical seta centrally and two-three setae near lateral margin, anterior margin with bifid setae ( Fig. 26 View FIGURES 26 – 35 b). Left mandible ( Fig. 27 View FIGURES 26 – 35 ) without setae between prostheca and mola, thumb of molar area transverse to anterior margin. Right mandible ( Fig. 28 View FIGURES 26 – 35 ) without setae between prostheca and mola. Hypopharynx ( Fig. 29 View FIGURES 26 – 35 ): lingua with rounded projection and longer than superlinguae. Maxillae ( Fig. 30 View FIGURES 26 – 35 ), palpi scarcely shorter than galea-lacinia, two segmented, segment II with a constriction. Labium ( Fig. 31 View FIGURES 26 – 35 ) with segment III of palpi rounded.

Thorax pale yellow. Pleura pale yellow, sterna whitish. Legs pale yellow. Dorsal edge of femora with a row of pointed spines, apically with a rounded projection and two blunt spines ( Fig. 32 View FIGURES 26 – 35 ). Tarsal claws 0.4 times the length of tarsi. Hind wing pads present.

Abdomen pale yellow, segments I–V with a reddish spot in the midline. Abdominal terga with covers, posterior margin of terga with spines as in Fig. 33 View FIGURES 26 – 35 . Sterna pale yellow with trachea pigmented, sterna II-VI with a tuft of long fine setae laterally on each side. Paraprocts with spines apically ( Fig. 34 View FIGURES 26 – 35 ). Gills ( Fig. 35 View FIGURES 26 – 35 ) translucent, trachea pigmented, 2.5 times the length of each tergum. Caudal filaments pale yellow, with flattened setae basally sclerotized (similar to Fig. 14 View FIGURES 4 – 14 b). Cerci with long spines toward external margin every two segments, terminal filament with long spines toward midline every two segments (similar to Fig. 35 View FIGURES 26 – 35 ).

Etymology. Vaimaca was one of the four charrúas taken to Paris in 1833 to be exhibited in the "Museum of the Man ". This fact crowned the humiliation and destruction of this people for the colonial Spanish model. We dedicate respectfully this species to his memory.

Diagnosis. Cloeodes vaimaca sp. nov. can be distinguished from the other species of the genus by the following combination of characters: 1) hind wing pads present; 2) lingua with rounded projection and longer than superlinguae ( Fig. 29 View FIGURES 26 – 35 ); 3) labium ( Fig. 31 View FIGURES 26 – 35 ) with segment III of palpi rounded; 3) dorsal margin of femora with a row of pointed spines, apically with a rounded projection and two blunt spines ( Fig. 32 View FIGURES 26 – 35 ); 4) abdominal color pattern as in Fig. 3 View FIGURES 1 – 3 , with segments I-V with a reddish spot in the midline
