Four species of Brentidae from Panama, Brentus quadrilineatus Sharp, 1895; Hemipsalis crassa Sharp, 1895; Rhynchoneus belti Sharp, 1895 and Schoenfeldtia impressicollis Senna, 1893 are reported. Two of them are reported (B. quadrilineatus and H. crassa) for the first time. Meanwhile, the geographical location of the other two species is not cited in Alessandra Sforzi & Luca Bartolozzi’s Brentidae of the World (R. belti and S. impressicollis) thus considered forgotten species of the country. Their taxonomy, diagnosis, type depositories, geographical distribution, material examined, and other relevant details are presented for all species.
