Abstract

The genus Legua Walker, 1870 comprises only two known species from Central America and Bra¬zil, with a notable scarcity of collected specimens. Herein, we provide a new contribution to our knowledge of the distribution of Legua rosea Amédégnato and Poulain, 1986 (Romaleinae: Leguini), that has a restricted distribution in Brazil, based on entomological collection data and social media information. Our records emphasize the importance of natural history collections and new tools for biodiversity studies.
