Macromalthinus santaremensis Brancucci, 1981   ( Fig. 53 View Figures 49-54 )

Macromalthinus santaremensis Brancucci, 1981a: 264   .

Material examined: HOLOTYPE ♂: [ BRAZIL, Pará] Santarém ( NHMB) ( Fig. 53 View Figures 49-54 ).  

Differential diagnosis: Head black; pronotum pale yellow, elytra black with apical yellow patches; males: fore femur swollen, with a distinct acute ventral tooth on distal third; aedeagus with right prolongation of tegmen broadly projected dorsally; left setiferous prolongation short; right paramere present.

Macromalthinus santaremensis   differs from M. maximiceps   and M.belemensis   by the presence of right paramere. It differs from the other Amazonian species by truncate ventral tooth on fore femur of males.

Distribution: Brazil (Pará state) ( Fig. 66 View Figures 66-69 ).

Remarks: Species described on a single male labelled ‘ Brésil, Santarem’, preserved in NHMB. No other specimens are known so far. The holotype lacks some tarsi and last antennomeres. The specimens collected in French Guiana, initially named as M. santaremensis   by Constantin (2016), are similar to the male holotype in the body shape and genitalia, but additional material reveals new elusive characters leading to the description of M. guyanensis   n. sp. and M. orapuensis   n. sp.
