Named in honour of Wilson Werner Koller, the collecter of one of the specimens examined. Description. Body. Head, pronotum, elytra and ventral surface dark brown or black, with a greenish metallic sheen. Length> 13 mm . Head. Foveiform punctures dense, touching on dorsal interocular surface. Punctures around clypeus shallower, smaller and more dispersed than those on the interocular surface. Dorsal interocular distance approximately four times eye width. Lateral margin of gena strongly curved outward, with row of setae around the eyes. Thorax. Surface of pronotum with dense and deep foveiform punctures, touching on the sides and anterior angles. Discal punctures smaller and more dispersed than those of surrounding surface. Posteromedial punctures usually separated by less than one diameter. Margin between lateral and posterior angles straight. Elytra. Lateral margins almost pararell ( Fig. 122 ) and surface slightly irregular (rugose). Elytral striae wider, carinate margins clearly separated (as in Fig. 75). Interstriae clearly convex, with its central portion nearly flat. Interstrial surface with foveiform punctures surrounded by microtubercles weakly defined, conspicuous on lateral of elytra. Interstriae usually more punctate on the sides, close to striae. Foveiform punctures of third interstria denser laterally (punctures can be so scattered at center of interstria to produce smooth midlongitudinal strip) (as in Fig. 86). Foveiform puncture surrounded by approximately six microtubercles. Basal carina of seventh interstria elongate, length about four or more times seventh interestria width. Basal carina of ninth interstria present in threequarters of elytra (not reaching anterior limit of apical carina of seventh interstria). Apical carina of third interstria rounded, better defined as tubercle, more prominent than apical carina of second and fourth interstriae. Length of apical carina of sixth interstria longer than that of apical carina of fifth interstria. Length of apical carina of seventh interstria less than or equal to the sum of lengths of apical carina of fifth and sixth interstriae. Pseudepipleural carina complete, visible entire length of epipleuron (as in Fig. 63). Material studied. Holotype : BRAZIL : MATO GROSSO DO SUL: Coxim, 26.II.1986 , Koller ( 1 ♂ CEMT ). Paratypes [5]: BRAZIL : MINAS GERAIS: São Roque de Minas, Parque Nacional Serra da Canastra, ( 20°15'17"S , 46°25'11"W ), 9.XI.2007 , M. F. Souza ( 1 ♂ 2 ♀ CEMT ); SÃO PAULO : Piracicaba, E.E.C.J.V., 30.IV.1966 ( 1 ♂ CEMT ); [no data] ( 1 ♂ CEMT ). Sampling methods. at light-trap [ 1 specimen ]. Habitat. Brazil (Minas Gerais and Mato Grosso) ( Fig. 94 ). From available data this species inhabits Cerrado. Diagnosis and remarks (within the icariforme subcomplex): length> 13 mm ; posteromedial punctures of pronotum usually separated by less than one diameter; length of apical carina of seventh interstria less than or equal to the sum of lengths of apical carinae of fifth and sixth interstriae; lateral margins of elytra almost parallel. The following aedeagus characters are also diagnostic: parameres symmetric and elongate, directed downward, almost at an angle of 60° with phallobase; apex weakly acuminate ( Fig. 19 ). Lamella copulatrix (LC): left lobe subrectangular (as in Fig. 41 ); right lobe “b”-shaped (as in Fig. 41 ). Superior right peripheral sclerite as in Fig. 49. Fronto-lateral peripheral sclerite (FLP) as in Fig. 56 . The punctures at center of elytral interstriae, on anterior portion of elytra, are the most dense of icariforme subcomplex. Apical carina of sixth interstria can present the same length of apical carina of fifth interstria.
