Porphyraspis picina Boheman, 1862: 40 (original description), syn. nov. Type localities. Porphyraspis picina : ‘Bahia’; D. rugosa : ‘Brasilia’. Type material examined. Porphyraspis picina : SYNTYPE : pinned: ‘ Bahia [w, p, cb] || Sommer [w, p, s] || Type. [w, p, s] || NHRS-JLKB | 000022626 [w, p, cb]’ ( NHRS ). Porphyraspis rugosa : HOLOTYPE : pinned, ‘64. | Brasil | 74 | rugosum | Boh [additionally written in pencil] Pty [w, hw, cb, green frame]’ ( ZSMC ). Remarks. BOHEMAN (1862) described Porphyraspis picina and differentiated it from P. rugosa by the darker colour of elytra. I have compared types of both taxa and in my opinion they are conspecific as they have identical formation of elytral costae, punctation, and shape of pronotum. Porphyraspis rugosa was based on a teneral, partially sclerotized and coloured specimen, resulting in a paler colouration than fully sclerotized P. picina . For these reasons I synonymize the latter taxon with P. rugosa . Distribution. Brazil : Bahia ( BOHEMAN 1862 ).
