Type Material. Bruchus cristatus   (4, NHRS): Lectotype, here designated, male ( Fig. 2 View Figs ), “[handwritten] ³” “[red, printed] Paratypus ”

“[handwritten] B: cristatus. \ Hoffmannseg. \ Para, Brasilia \ Klug.” “[printed] NHRS-JONI \ 000027566” “ Lectotype / Bruchus cristatus Fåhraeus, 1839   / design. I. R. Jorge”; 1 paralectotype female ( Fig. 3 View Figs ) “[handwritten] ♀ ” “[red, printed] Paratypus ” “[handwritten] Brasilia. in \ sem: Bahuinia \ (Schnellia.) \ Faldermann.” “[printed] NHRS-JONI \ 000027567” “ Paralectotype / Bruchus cristatus Fåhraeus, 1839   / design. I. R. Jorge ”   ; 1 paralectotype male ( Fig. 4 View Figs ) “[handwritten] ³” “[red, printed] Typus ” “[handwritten] Br: gibbicollis \ Fald.\ Brazil: Faldermann ” “[printed] NHRS-JONI \ 000000469” “ Paralectotype / Bruchus cristatus Fåhraeus, 1839   / design. I. R. Jorge ”   ; 1 paralectotype female ( Fig.5 View Figs ) “[handwritten] Br : gibbicollis \ Fald. \ Brazil: Faldermann ” “[handwritten] ♀ ” “[red, printed] Allotypus ” “[printed] NHRS-JONI \ 000000470” “ Paralectotype / Bruchus cristatus Fåhraeus, 1839   / design. I. R. Jorge ”   .

In the original description, Fahraeus in Schoenherr (1839) indicated B. gibbicollis Faldermann   as a name in litt. and a synonym of B. cristatus   . No specimens were designated as types. We received four specimens from the NHRS. Bruchus cristatus   : one male “ PARATYPUS ” ( Fig. 2 View Figs ); one unidentified female “ PARATYPUS ” ( Fig. 3 View Figs ); B. gibbicollis   : one headless male as “TYPUS” ( Fig. 4 View Figs ); and B. gibbicollis   : one female “ ALLOTYPUS ” ( Fig. 5 View Figs ). Label data of all specimens match the information given in the original description of B. cristatus   : type locality (“ Brazil ”), collectors (“Klug”- B. cristatus   , “Faldermann”- B. gibbicollis   and unidentified specimen), and alleged authorship of the species names (“Hoffmannsegg” - B. cristatus   , “Faldermann” - B. gibbicollis   ), host plants (“Bahuniae, Schnelliae”- unidentified specimen) ( Figs. 2–5 View Figs ). Based on this information, we are confident that Fåhraeus in Schoenherr (1839) had all these four specimens to examine.

The red type labels were probably inadvertently added later, probably not by Fåhraeus, since the red tone and letter font are different ( Figs. 2–5 View Figs ). The labels “TYPUS” and “ ALLOTYPUS ” ( Figs. 4, 5 View Figs ) are erroneous because B. gibbicollis   is a nomem nudum, and those indicating “ PARATYPUS ” ( Figs. 2, 3 View Figs ) are consequences of this previous procedure. Therefore, we selected the only male specimen labeled as B. cristatus   , with the red label “ PARATYPUS ” and the only male with a head, to designate as the lectotype of B. cristatus   ( Fig. 2 View Figs ).

Pseudopachymerus cristatus var. velutinotatus   (2, BMNH): Lectotype, here designated, male, “[handwritten] Pseudopachymerus   \ cristatus Fhr   \ v. velutinotatus   \ Pic” “[handwritten] 1908” “ BRAZIL \ bahia \ Dr. G. Bondar” “[facing down] Pres. by \ Imp. Inst. Ent. \ B. M. 1936-531.” “ Lectotype / Pseudopachymerus cristatus var. velutinotatus Pic, 1936   / design. I. R. Jorge”; 1 paralectotype male “[handwritten, illegible word]” “[handwritten] Pseudopachymerus   \ cristatus Fahraeus   ” “[handwritten] v. nov. \ velutinotatus” “[handwritten] 1908” “ BRAZIL \ bahia \ Dr. G. Bondar” “[facing down] Pres. by \ Imp. Inst. Ent. \ B. M. 1936-531.” “ Paralectotype / Pseudopachymerus cristatus var. velutinotatus Pic, 1936   / design. I. R. Jorge”.

In the original description, Pic (1936) did not indicate the number of specimens he studied. However, two specimens were received from BMNH, which bear locality data identical to that given in the original description, viz., Brazil, Bahia. The color differences mentioned by Pic (1936) between P. cristatus   and P. cristatus var. velutinotatus   are considered herein intraspecific variation, and no other morphological differences were found. In Udayagiri and Wadhi (1989), the variety name   was treated as a junior synonym of P. cristatus   . However, the authors did not state if the type material was examined. We, however, had the opportunity to study firsthand two types of P. cristatus velutinotatus   , and based on that, we confirm the synonymy. Thus, one well-preserved specimen is herein designated as the lectotype of P. cristatus velutinotatus   .

Bruchus godmani   ( 1, BMNH): Holotype, male “[handwritten, with fixed specimen] Bruchus godmani   . [on left vertical] \ Type D. S. [on left vertical] \ Bugaba. \ Panama. Champion.” “[circular label with red border, printed] TYPE” “[printed] sp. Fig.d.” “[printed] Bugaba. \ Panama. \ Champion.” “[printed] B. C. A. Col. V. \ Bruchus   \ godmani, \ Sharp.”.  

Sharp (1885) mentioned that he only studied one specimen, which was sent to us by the BMNH with collecting data labels identical to the information given in the original description (“ Panama, Bugaba, Champion”). We are confident that this specimen is the holotype. After studying this specimen, we conclude that B. godmani   is a new junior synonym of B. cristatus   , since no significant morphological differences between the two were detected.

Kingsolver and Whitehead (1974) mentioned Pachymerus triquetrus Motschulsky, 1874   as a probable synonym of Caryedes cristatus   . However, it was not possible to examine the type material for our study and, thereby, this possible synonymy needs to be confirmed in the future.
