Primary type

Holotype ( Fig. 28D View Fig )

FRENCH GUIANA • “Holotype, Mycotretus dorsonotatus Lacordaire, 1842 [red label, handwritten]”; MRSN.

Other specimens examined

BRAZIL • 1 ♂ (dissected); “Coleção M. Alvarenga [printed] \ Diamantino 400 m, M. Grosso Brasil, XI. 1983, A. Cerutti [printed]”; MNRJ .

Distribution

Guiana, French Guiana, Peru, Panama, North and Central-West Brazil.

Remarks

Mycotretus dorsonotatus Lacordaire and M. quadristriolatus Kuhnt are phenotypically almost identical and we consider them conspecifics. The medial elytral spots present on M. dorsonotatus are absent in M. alternans Gorham (probably a case of incomplete pigmentation), but we dissected indivuals possessing both colorations and observed that their male genitalia are identical.
