P. Zikán/  Plochionocerus profundepunctatusBernh.Type unic. / Chicago NHMus, M. Bernhauer Collection” ( FMNH).  Additional material( 3 specimens). “ S. America:  BRAZIL” ( 1♀, BMNH). “ S. America” ( 1♂, 1♀, BMNH).   Redescription.Total length 14.2–20.7 mm. Body black, shining with reddish brown antennomeres 1–3, mouthparts, tarsi and genital segment. Head and pronotum with sparse, short setae, remainder of body with dense, long setae.  Head. Oval, posteriorly narrowed (similar to Fig. 14), 1.41x as long as wide; slightly convex dorsally and ventrally; ventral surface with umbilicate punctures moderately dense separated by 2–3x their width ( Fig. 23) and unevenly distributed; temple with superior and inferior temporal carinae and a flattened area ( Fig. 30); eyes small (0.22x length of head), interocular distance 0.68x cephalic width; first antennomere 1.86x as long as antennomeres 2–3 combined, apical antennomere 0.94x as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54); mandibles with external channel; elongate apical maxillary palpomere ( Fig. 38), 1.87x as long as preapical palpomere; apical labial palpomere moderately wide and flattened toward apex ( Fig. 44), nearly twice as long as preapical palpomere.  Thorax. Pronotum 1.5x as long as wide; 1.07x as wide as head; with dense umbilicate punctures, except for narrow, longitudinal impunctate area, which is wider at anterior third and narrower in the remainder of its length; without depressed areas in posterior third ( Fig. 49). Elytra as long as pronotum, with dense setae on elytral disc. Prosternum with sparser setae than mesosternum and metasternum and with small, central, longitudinal carinate line.  Abdomen. Densely covered with setae as on elytra, these setae denser than on head and pronotum.  Aedeagus. Pear-shaped (lateral margins of median lobe convex); total length 1.9 mm; parameres 0.33x as long as median lobe; apical area of median lobe 0.30x as long as total length, internal sac with weakly sclerotized structures ( Fig. 70).  Variation.The genital segment of males is red, while in females it is reddish brown. In one specimen, the elytra are as long as the pronotum.  Comparison.This species can be confused with remaining species of the “formicaria” species group, but only  R. sharpiand  R. glabrinotumhave an oval head that is posteriorly narrowed. It can be separated from  R. glabrinotumby the presence of superior and inferior temporal carinae on the temple of the head, while  R. glabrinotumdoes not have these carinae. It can be distinguished from  R. sharpiby its short eyes (less than 0.25x as long as head), ventral surface of the head with moderately dense umbilicate punctures separated by 2–3x their width and the internal sac of the aedeagus with weakly sclerotized structures. In contrast,  R. sharpihas long eyes (0.25–0.30x as long as head), dense umbilicate punctures on the ventral surface of the head separated by less than twice their width and the internal aedeagus sac with moderately visible sclerotized structures.   Remarks.The label data of the type specimen agree with the information in the original description, when one specimen, the holotype, is recorded ( Bernhauer, 1927).  Geographical distribution. Brazil( Herman, 2001).
