Abstract
New combinations for Paratibraca amazonica (Gonçalves & Campos, 2016) comb. n., Paratibraca dubia (Campos & Souza, 2016) comb. n. and Paratibraca spinosa (Campos & Grazia, 1998) comb. n. are proposed. Paratibraca rideri Barros, Barão & Grazia sp. nov. from Brazil is described. Additions to the genus description, and photographs of type-specimens are provided.
Highlights
Paratibraca Campos & Grazia, 1995 (Hemiptera: Pentatomidae) used to be a monotypic genus, included in the Mecocephala group (Carpocorini Mulsant & Rey, 1866)
Detailed examination of the seven species currently included in Glyphepomis showed that G. amazonica, G. dubia and G. spinosa share diagnostics characters to the species included in Paratibraca, such as the outline of mandibular plates, form of bucculae, outline of anterolateral margins of pronotum, and genitalic characters of both sexes
General colour light brown dorsally; ventral surface dark brown; body densely punctate with dark punctures
Summary
Paratibraca Campos & Grazia, 1995 (Hemiptera: Pentatomidae) used to be a monotypic genus, included in the Mecocephala group (Carpocorini Mulsant & Rey, 1866). Because of the head and male genitalic morphologies Paratibraca have been associated with Hypatropis Bergroth, 1891, Mecocephala Dallas, 1851, Glyphepomis Berg, 1891, and Tibraca Stål, 1860. Results of an ongoing study about the phylogenetic relationships within the Mecocephala group (Barros et al in prep.) suggested that those three species are more related to Paratibraca than to Glyphepomis.
