Redescription.Total length 11.3–12.8 mm. Body black, with antennomeres 4–11, labrum, palpi, tarsi, posterior 2/3 of penultimate visible abdominal segment and last visible abdominal segment reddish brown. Head. Ovally quadrate (similar to Fig. 19); 1.21x as long as wide; dorsally and ventrally slightly convex; dorsal surface with very dense umbilicate punctures, ventral surface with dense umbilicate punctures separated by 1–2x their width ( Fig. 24); temple convex ( Fig. 27); eyes 0.3x as long as head, interocular distance 0.67x cephalic width (at eye level); first antennomere 1.88x as long as antennomeres 2–3 combined, apical antennomere as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54); with mandibular external channel; apical maxillary palpomere conical ( Fig. 40), as long as preapical palpomere; apical labial palpomere asymmetrically conical ( Fig. 45), longer than preapical palpomere. Thorax. Pronotum 1.41x as long as wide; 1.07x as wide as head; with dense fine punctures, except for wide longitudinal impunctate area ( Fig. 52); with depressed area poorly developed at each side of posterior third. Elytra as long as pronotum; with dense fine setae as on pronotum. Prosternum transverse, with setae sparser than on meso and metasternum. Abdomen. Densely covered with long, pale setae. Aedeagus. Elongate; total length 1.4 mm; parameres 0.34x as long as median lobe; apical area of median lobe 0.29x as long as total length of median lobe; internal sac with weakly sclerotized structures ( Fig. 82). Variation.Two specimens have antennomeres 4–11, mouthparts, tarsi and two last visible abdominal segments brown, almost black. Some specimens have the apex of the last antennomere yellow. Depressed areas at each side of posterior third of pronotum are slightly visible to inconspicuous. Comparison.This species can be confused with R. longiceps, R. nitida, R. mesoamericana, R. lescheniand R. brasilianadue to the similar shape of the apical maxillary and labial palpomeres and the punctures of the pronotum. It is distinguished from R. longicepsand R. nitidaby an ovally quadrate head (length/width proportion: 1.17–1.25), while in the latter two species the head is ovally elongate (length/width proportion: 1.26–1.50). It can be separated from R. mesoamericanaby the temple of head convex and by its oval aedeagus with a widened base of the median lobe. It is separated from R. lescheniand R. brasilianaby the slightly convex ventral surface of head and denser umbilicate punctures on this area (the latter two species have clearly convex ventral surface of the head and sparser umbilicate punctures).
Remarks.In spite of the fact that it was impossible to locate the holotypeof R. dalmasi, I propose this species as a junior synonym of R. minorbased on the following considerations. Of all previously studied specimens of any species from Colombia, only one was identified by Bernhauer as R. dalmasiand this specimen corresponds morphologically to R. minor.In the original description of R. dalmasi, the characteristics given by Fauvel (1901)are not very useful for the identification at the species level, but some of them, such as head almost flat and quadrate, dense umbilicate punctures on the ventral surface of the head, fine punctuation of the pronotum, similar length of head and pronotum and the total length ( 11 mm), completely correspond with R. minor. Additionally, the same author ( Fauvel, 1901) indicates that R. dalmasiis similar to “ Pl. minorShp., from Amazonas”. Finally, seven species are recorded in this work from Colombiaand two of them could be excluded from this taxonomic problem because their head and pronotum have dense umbilicate punctures ( R. flagellicornisand R. formicaria). One of the remaining four species is proposed here as a new species ( R. fimetariamimus), that has an oval, posteriorly narrowed head, temple with temporal carinae and a concave area, characteristics that were not included in the original descriptions of R. dalmasiand R. minor. Renda fimetariacan also be excluded as it has a very characteristic head with large eyes, and it is difficult to confuse this species with any other. Renda clavicornishas a convex head, with superior and inferior temporal carinae and a concave area, characters that were not observed in the study of R. minor. The remaining species are R. dalmasiand R. minor, which are proposed here as synonyms. Considering the present proposed synonymy and the probable confusion of R. minorwith other similar species, a lectotypefor this species was designated from one of the two examined specimens which have the same label data as those indicated in the original description ( Sharp, 1876). Geographic distribution.Previously recorded from Brazil( R. minor) and Colombia( R. dalmasi) ( Herman, 2001). It is recorded here for the first time from Bolivia, Ecuador, French Guiana, Paraguay, Peruand Surinam.
