( Figs 9 , 12, 37, 49, 52, 55, 59) Type material. Holotype from DZUP , male, labeled as, ‘ Brasil , PR, Palotina/ Parque Estadual de São/ Camilo (FIT+malaise)/ 28-X-2010 / E. Caron, col.’ [white label, printed]. Eight paratypes , one male and three females from DZUP , and one male and three females from FMNH , labeled as, ‘ Brasil , PR, Palotina/ Parque Estadual de São/ Camilo (FIT+malaise)/ 04-XI-2010 / E. Caron, col.’ [white label, printed]. Diagnosis. Xenopgyus sancticamillus , sp. nov. can be differentiated from X. petilicolis , sp. nov. by the number and shape of apical teeth of the median lobe and by the shape of the paramere apex and the distribution pattern of the peg setae, in which X. sancticamillus , sp. nov. has only one large tooth in the apex of the median lobe ( Fig. 49 ) and has the apex of the paramere rounded and with peg setae distributed along its margin (Fig. 55). Description. BL: 7.5–9.0 mm, BW: 2.0 mm. Head and pronotum metallic brown to green, elytra and abdomen brownish and abdominal segments VIII-X light brown ( Fig. 9 ). Pronotum with setal punctuations evenly distributed except for the longitudinal median region (Fig. 12). Eyes occupy almost all lateral sides of the head. Antenna scape shorter than antennomeres II and III combined; antennomere IV evidently longer than wide; antennomeres IV-XI with microsetae; antennomere XI asymmetric. Pronotum shorter than elytra length. Mesoventrite process with apex slightly rounded; metatarsomeres II-IV nonbilobate. Tergite V without arched carina; sternite VII without porous structure; sternite VIII of male with apical margin medially emarginate (Fig. 37). Median lobe with non-bulbous base ( Fig. 49 ); apex slightly emarginate, smooth carina in ‘V’ shape in the apical third, one large apical teeth in hook shape (Fig. 52); parameres fused in a single plate and with peg setae around the rounded apex (Fig. 55). Geographical record. Brazil : Minas Gerais; Paraná. Argentina : Chaco ( Fig. 59 ). Etymology. The specific name refers to the locality where the type material was collected, Biological Reserve of 'São Camilo'. In Portuguese ‘São Camilo’ refers to a Catholic saint and the specific name is a Latin compound name: adjective stem sanct- (saint)+ connective vowel i + substantive camillus.
