Rivudiva trichobasis – Boldrini et al. 2012: 93. — Salles et al. 2020: 49.

Diagnosis

NYMPH. 1) labrum distal margin straight; 2) apex of segment II of maxillary palp with strong inner projection.

Material examined

BRAZIL • 2 nymphs (one on slide and other without head); Maranhão, River Farinha, BR-010, near the bridge; 06°31′47.3″ S, 47°28′11.4″ W; 22 Jul. 2010; R. Boldrini, P.V. Cruz and Hamada N. leg.; UFRR .

Comments

In Boldrini et al. (2012), this unidentifiable specimen was named as R. trichobasis . The specimens studied are in bad condition, with essential structures broken and missing, such as head, labium, hypopharynx, part of maxilla and abdomen. However, based on the maxillary palp, it is probably a new species.
