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. 17A ); antenna 15-segmented and filiform in females ( Fig. 17D ), 14-segmented in males; first male flagellomere not modified ( Fig. 20B ). Mesosoma higher than wide; pronotal shoulders angular ( Fig. 17C ); 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. 17E ). Forewing with closed radial cell ( Fig. 17F ). Material examined: BRAZIL : Santa Catarina : São Bento do Sul , CEPA Rugendas , 26°19’25.6”S , 49°18’26.5”W , 14-17.x.2001 , A.M.

A.L. Quadros det. 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. 12A , 17A , 18A ), the angular pronotal shoulders ( Figs. 17C , 18C ), well developed epomia and forewing with closed radial cell ( Figs. 5A , 17F , 18D ), with some Aclista species with teeth, one on each scutellar bridge, near the posterolateral margin of the scutellar fovea ( Figs. 17E , 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. 24B ).
