Type species. Rosalbopsis wappesi sp. nov. Etymology . Allusive to its general appearance as in some species of Rosalba Thomson, 1864 (Apomecynini) ; opsis, from Greek όψις (“aspect”, “appearance”). Feminine gender. Description . Female . Body elongate, moderate size. Head slightly elongate behind eyes; frons transverse. Eyes coarsely faceted; connection between upper and lower lobes wide, with 5 ommatidia; distanced between upper eye lobes slight wider than width of one lobe. Genal apex rounded. Antennae distinctly longer than body, 11- segmented; scape elongate, subcylindrical, shorter than antennomere III, dorsally without depression, without apical cicatrix; antennomeres filiform, with sparse, thick setae ventrally, about 1.5 times longer than diameter of antennomere. Prothorax cylindrical; sides with blunt, small tubercle, slightly widened from base and apex to lateral tubercle. Pronotal disc without tubercles. Procoxal cavities distinctly angulate laterally; mesocoxal cavities closed laterally, but lateral lobes of mesosternum not touching base of metasternum. Pro- and mesosternal process wide, distinctly not laminiform; mesosternal process without tubercle. Elytra without differentiated structure on basal third, laterally parallel-sided at basal 2/3, gradually tapering to apex at distal third; apex slightly obliquely truncate (rounded appearance); surface without long, erect setae. Legs not notably short, with apex of mesofemora reaching at about apex of third abdominal segment; mesotibiae slightly obliquely sulcate dorsally; metatarsomere V almost as long as I–III together. Remarks . Rosalbopsis belongs to the group of genera with scape without apical cicatrix, prothorax with lateral tubercle and elytra without differentiated structure on basal third of the elytra. It differs from Disgregus Galileo & Martins, 2009 , by the filiform antennomeres and without abundant long setae, while in Disgregus the antennomeres have long and abundant setae (mainly V–XI), V–XI are distinctly shortened, and V–X are somewhat serrate. Rosalbopsis differs from Stereomerus Melzer, 1935 , by the head not elongate behind eyes (distinctly elongate in Stereomerus ), legs longer (short in Stereomerus ), apex of metafemora reaching at about apex of abdominal segment III (usually slightly surpassing apex of I in Stereomerus ). It can be separated from Esaguasu Galileo & Martins, 2007 , mainly by the elytral apex without distinct spine at outer angle (present in Esaguasu ) and by the mesosternal process without tubercle (with rounded tubercle sulcate centrally in Esaguasu ). It differs from Heteresmia Monné, 2005 , by the scape and antennomeres without long and abundant setae, while in Heteresmia the scape, pedicel, antennomere III and base of IV have dense and long setae throughout. Rosalbopsis differs from Atelodesmis Buquet, 1857 , mainly by the distance between upper eye lobes slightly wider than width of one lobe (distinctly wider than width of one lobe in Atelodesmis ). It differs from Aconopteroides Breuning, 1959 , by the elytra not strongly narrowed from base to apex (notably tapering in Aconopteroides ), and by the elytral apex subrounded (strongly obliquely truncate in notably tapering in Aconopteroides ). It differs from Tigrinestola Breuning, 1949 , mainly by the sides of prothorax slightly enlarged from base and apex toward lateral tubercle and by the lateral tubercle smaller (more distinctly enlarged and with larger lateral tubercle in Tigrinestola ), and by the metatarsomere V almost as long as I–III together (about as long as I in Tigrinestola ). Rosalbopsis can be separated from Pseudestola Breuning, 1940 , by the elytra not together rounded at apex (rounded in Pseudestola ), and by the metatarsomere V almost as long as I–III together (about as long as I in Pseudestola ). It differs from Mimestola Breuning, 1940 , by the small tubercle at sides of prothorax (larger in Mimestola ), and by the pronotal disc without tubercles (present in Mimestola ). Rosalbopsis differs from Tesapeus Galileo & Martins, 2012 , by the lateral tubercle of prothorax small and placed at about mid-length (large and place near base in Tesapeus ), and by the eyes not divided (divided in Tesapeus ). It differs from Ibypeba Martins & Galileo, 2012 , by the elytra without long and erect setae (present in Ibypeba ), and by the lateral tubercle of the prothorax placed about mid-length (near base in Ibypeba ). Finally, it differs from Micratelodesmis Martins & Galileo, 2012 , by the basal antennomeres without long and abundant setae (present in Micratelodesmis ), and by the elytra without long and erect setae (present in Micratelodesmis ).
