Odontopsilus Kieffer, 1909 

( Figs. 17View FIGURE 17, 20BView FIGURE 20, 24BView FIGURE 24)

Total of specimens found: 182 (73 females and 109 males) in one morphospecies.

Diagnosis: Overall size between 2.4 and 3.75 mm; mandibles long (mandible length longer than the distance between the ventrolateral margins of the head, near the bases of the mandibles), sickle-shaped ( Fig. 17AView FIGURE 17); antenna 15-segmented and filiform in females ( Fig. 17DView FIGURE 17), 14-segmented in males; first male flagellomere not modified ( Fig. 20BView FIGURE 20). Mesosoma higher than wide; pronotal shoulders angular ( Fig. 17CView FIGURE 17); epomia well developed; presence of teeth, one on each scutellar bridge, near the posterolateral margin of the scutellar fovea, plus a small tooth in the middle posterior part of the scutellar disc ( Fig. 17EView FIGURE 17). Forewing with closed radial cell ( Fig. 17FView FIGURE 17).

Remarks: There is only one described species of Odontopsilus  in the world ( Johnson, 1992), O. tenuicornis Kieffer, 1909  , which was recorded also in the Neotropics (Pachitea, Peru) ( Kieffer, 1909). It shares character states with Aclista  such as the sickle-shaped mandibles ( Figs. 12AView FIGURE 12, 17AView FIGURE 17, 18AView FIGURE 18), the angular pronotal shoulders ( Figs. 17CView FIGURE 17, 18CView FIGURE 18), well developed epomia and forewing with closed radial cell ( Figs. 5AView FIGURE 5, 17FView FIGURE 17, 18DView FIGURE 18), with some Aclista  species with teeth, one on each scutellar bridge, near the posterolateral margin of the scutellar fovea ( Figs. 17EView FIGURE 17, 19View FIGURE 19 B-C). The Odontopsilus  species might represent an Aclista  with significant modifications in the scutellum.

Distribution: In our study, it was recorded from Santa Catarina to Pernambuco states ( Fig. 24BView FIGURE 24).
