Type Material. Bruchus longifrons ( 4, BMNH): Lectotype designated by Kingsolver and Whitehead (1974), male: “[handwritten with fixed specimen] Bruchus longi- \ frons. Type D. S. \ David. Panama. \ Champion.” “[circular label with dark blue border] LECTO- \ TYPE” “[circular label with red border] TYPE” “David, Panamá. \ Champion.” “ B. C. A. Col. V. \ Bruchus \ longifrons, \ Sharp.” “Sharp Coll. \ 1905-313.”; 1 paralectotype female “[handwritten with fixed specimen] Bruchus longi- \ frons. Type. Ex \ parte D. S. \ David. Panama. \ Champion.” “[circular label with light blue border] PARA- \ LECTO- \ TYPE” “David, Panama, \ Champion” “ B. C. A. Col. V. \ Bruchus \ longifrons, \ Sharp.” “[label facing down] Sharp Coll. \ 1905-313.”; 1 paralectotype male “[handwritten with fixed specimen] Bruchus longi- \ frons D. S. \ Bugaba. Champion” “[circular label with light blue border] PARA- \ LECTO- \ TYPE” “Bugaba, Panama, \ Champion” “ B. C. A. Col. V. \ Bruchus \ longifrons, \ Sharp.” “ Sp.Fig. d.”; 1 paralectotype of undetermined sex [without head] “[circular label with light blue border] PARA- \ LECTO- \ TYPE” “Bugaba, Panama, \ Champion” “ B. C. A. Col. V. \ Bruchus \ longifrons, \ Sharp.” “[handwritten] longifrons”.

Sharp (1885) mentioned that four specimens were examined, and all of them were loaned to us by the BMNH. These specimens have labels with collecting data identical to the information given in the original description (“Panama, Bugaba, Champion ”). The male specimen labeled “type” is here designated as the lectotype and the other three specimens are now paralectotypes of B. longifrons.

Bruchus diversipes (1, MNHN): Lectotype, here designated, male: “[printed, green] Jatahy \ Prov. Goyas. Brésil \ Sept. A Nov. 97” “[handwritten] diversipes \ n sp” “[printed, red] HOLOTYPE” “vial with genitalia” “[handwritten] diversipes \ Pic \ det. [printed] 70 [handwritten] \ J. M. Kingsolver [printed]” “[handwritten] Caryedes \ diversipes \ (Pic, 1927) \ Ribeiro-Costa, C. S. det. 200 [printed] 7 [handwritten]” “[printed] MUSÉUM PARIS \ 1958 \ Coll. M. PIC”. “Lectotype / Bruchus diversipes Sharp, 1885 / design. I. R. Jorge ”.

Pic (1927) did not indicate the number of specimens studied, but we received on loan one specimen from the MNHN that matches the information given in the original description. The collecting label data is identical to the information given in the original description, viz., Brazil. This specimen is here designated as the lectotype. By comparing the type material of B. diversipes with that of B. longifrons, we found that the difference is in the presence/absence of a tooth at the base of the fourth elytral stria. This character varies intraspecifically (Romero Nápoles and Mar´ın Jarrillo 2013). It should be stressed that the male genitalia are identical in both males. Consequently, B. diversipes is a new junior synonym of B. longifrons.
