Type Material. Bruchus juno ( 2, BMNH). Lectotype designated by Kingsolver and Whitehead (1974), male, “[handwritten, with fixed specimen] Bruchus boops juno \ Type (³) D. S. \ David. Chiriqui. \ Champion.” “[circular label with dark blue border, printed] LECTO- \ TYPE” “[circular label, red border, facing down, printed] TYPE” “[printed] David, Chiriqui. \ Champion.” “[printed] B. C. A. Col. V. \ Bruchus \ juno, \ Sharp.” “[label facing down, printed] Sharp Coll. \ 1905-313.”; 1 paralectotype female “[circular label, light blue border, printed] PARA- \ LECTO- \ TYPE” “[printed] David, Chiriqui, \ Champion” “[printed] B. C. A. Col. V. \ Bruchus \ juno, \ Sharp.”.

Sharp (1885) mentioned that four specimens were studied for the description. However, we received only two specimens from the BMNH, with collecting label data identical to the information given in the original description (“ Chiriqui, Champion ”) .

Pseudopachymerus (Falsobruchus) gounellei (4, MNHN): Lectotype, here designated, male “[handwritten] Pernambuco \ ( Bresil)” “[handwritten] Bresil \ (gounellei)” “[handwritten, red] type” “[handwritten] Falsobruchus \ gounellei \ n sp” “[printed, red] HOLOTYPE ” “[printed] MUSÉUM PARIS \ 1958 \ Coll.

PIC” “[printed, red] PARATYPE ” “ Paralectotype / Pseudopachymerus (Falsobruchus) gounellei Pic, 1923 / design. I. R. Jorge”.

Four specimens were received from the MNHN, with locality data identical to the information given in Pic’ s original description (“ Brazil, Pernambuco ”) except for one of the specimens, which does not have locality labels associated with it. This specimen, which also does not have Pic’ s handwritten label, has the museum label recognizing it as part of Pic’ s collection (similar to Fig. 1 , label “[printed] MUSÉUM PARIS \ 1958 \ Coll. M. PIC”), and was prepared in a similar manner as the other syntypes .

While reviewing C. juno, Kingsolver and Whitehead (1974) reported that this species has a contrasting dark patch on the metepisternum, a characteristic that is less developed in C. gounellei , a representative of the South American fauna. This difference is considered by us to be intraspecific variation. Consequently, P. (Falsobruchus) gounellei is here deemed a new junior synonym of B. juno . The male with Pic’ s label “type” is here designated as the lectotype of P. gounellei .
