Primary type

Lectotype, here designated ( Fig. 14B )

BRAZIL • “maculifrons Chevrolat. [handwritten] \ femoratus Chevrolat. [handwritten]”; MRSN.

Remarks

New junior synonym of M. ornatus ( Duponchel, 1825) ( Fig. 14A , see above). The names “ maculifrons Chevrolat” and “ femoratus Chevrolat” are nomina nuda, and appear only in the catalogue of Gemminger & Harold (1876) under the name “ maculosus Duponch ”. We have located only the specimen with two labels (“ maculifrons Chevrolat” and “ femoratus Chevrolat”) among the Dejean specimens in the Brême collection ( Fig. 14B ) and selected it as the lectotype of M. maculosus (see the Remarks for M. ocellatus (Germar) above).
