( Figs. 1E , 2 )

Crytomenus marginalis Signoret, 1881: 201 ; Lethierry & Severin, 1893: 62. Cyrtomenus (Syllobus) marginalis: Froeschner, 1960: 521 .

Material examined: Photos provided by Harald Bruckner from the holotype deposited in NHM Wien, a female specimen labeled: “ Brasil ”, coll. Signoret.

Distribution: Brazil.

Remarks: The species is only known from the type specimen, that despite the lack of a more precise locality and material for study, presents typical features as the general shape, the expanded posterior tibia and the appearance of the peritreme to be placed in Cyrtomenus ; also the row of numerous setigerous punctures on the lateral submargin of the pronotum (25) and on the costa (21–23) ( Fig. 1E ), are unique for C. marginalis within the genus.
