Etymology. This species is dedicated to Dr. Enrique Morelli, entomologist of Universidad de la República ( Uruguay) who continually stimulates the study of the aquatic insects of Uruguay.

Discussion. This species can be distinguished from the other species of the genus by the following combination of characters: 1) frontal keel present; 2) antennae short, 1.5 times the head capsule; 3) segment II of labial palpi with rounded projection, 2 times width of segment III ( Fig. 20 View FIGURES 13–25 ); 4) tarsal claws with two rows of minute denticles ( Fig. 22 View FIGURES 13–25 ); 5) hind wing pads absent; 6) general color pattern with head and thorax with small spots, abdomen with segment II–VII with medial elongate spot as in Fig. 13 View FIGURES 13–25 ; 7 View FIGURES 1–12 ) posterior margin of terga with spines as long as wide ( Fig. 23 View FIGURES 13–25 ); 8) paraprocts with 8–10 spines apically ( Fig. 24 View FIGURES 13–25 ); 9) terminal filament with crown of small spines on each segment ( Fig. 25 View FIGURES 13–25 ).
