H. Schubart (INPA).</p> <p>Paratype: Petropolis, Meio da Serra, male, 15.8.1960, leg. H. Schubart (UIC).</p> <p>Diagnosis: Together with O. laeviusculus, the species has a specific combination of characters. It has no setiferous punctation and the aedeagus is symmetric with both sides of apical lobe sclerotised. Concerning the lateral margin of the pronotum and the absent spines on the posterior face of the protibia the species must be placed to the genus Osoriellus. The species resembles O. laeviusculus in the absence of the setiferous punctation, but the punctation is finer and sparser and the anterior edge of the clypeus is crenate, whereas it is even in O. laeviusculus. Furthermore, the microsculpture of the pronotum in O. schubarti is netlike, but longitudinal in O. laeviusculus. A crenate anterior edge and a symmetric aedeagus are also found in the O.- oculatus -group, but these species have a setiferous punctation.</p> <p>Description: Length: 5.2 mm.

In contrast to the species of that group, the aedeagus of O. spinosus is asymmetric. The eyes are slightly less prominent than in O. oculatus. The punctation of the head is less dense, but the pronotal punctation is denser than in O. oculatus. In particular, the dentation of the clypeus differs from O. hanagarthi and O. oculatus. The pronotal shape differs distinctly from O. hanagarthi, since the sides are evenly narrowed such as in O. oculatus and without slight emargination. Within the O.- bicornis -group the species is characterised by the denticulate anterior edge of the clypeus.</p> <p>Description: Length: 3.5 mm.

C. Bruch (holotype FMNH); female leg. Ogloblin (as O. ogloblini in FMNH); Buenos Aires, female, 15.12.1899, leg. Silvestri (as O. acupunctus in FMNH).</p> <p>Further material examined: Paraguay: Villarica (25°45'S, 56°25'W), 125 m elevation, 16 specimens from July, August, September, October, November, January and March 1937, leg. F. Schade (AMNH, UIC); 1 male without further data, identified by Bernhauer as O. acupunctus, 3 females, leg. Drake identified as O. frater by Bernhauer (SDEI); Brazil: Pará, Jacaréacanga, at light, male, Jan. 1970, leg. F.R. Barbosa (AMNH).</p> <p>Diagnosis: The species highly resembles O. mexicanus and O. brevipennis in size and shape of the pronotum. It can be differentiated from O. mexicanus by the presence of at least remains of microsculpture on the head. In contrast to O. brevipennis, the shape of the pronotum is less triangular. BERNHAUER (1933) described O. acupunctus and O. ogloblini considering the nearly lacking microsculpture of the head and the deeper punctures on the elytra. Unfortunately, the type specimens of O. ogloblini and O. acupunctus are females and, therefore, a study of the aedegaus was not possible. Within the large number of specimens in the AMNH the microsculpture of the head varies extremely from very deep ground-sculpture with slightly shiny surface to nearly polished surface. Additionally, the microsculpture of the abdomen varies in the same way. Furthermore, the row of punctures along the impunctate midline of the pronotum is not a differentiating character between N. argentinus and N. ogloblini. I found no other characters to separate the species even between the aedeagi of the non-type O. acupunctus of SDEI and O. argentinus. Thus, the species described by BERNHAUER (1933) are within the variability of O. argentinus.</p> <p>Description: Length: 5.3 – 6.0 mm long.

In particular, O. bicolor and O. loksai resemble O. ashei in the absence of the pronotal microsculpture and the smaller size than the other three species. Compared to O. bicolor and O. loksai, the pronotal punctation in O. ashei is denser and coarser.

A few specimens of O. debilis were not longer than 4.9 mm. It resembles O. trapezoides in size, but the shape of the pronotum in O. trapezoides is more convergent; whereas in O. debilis the pronotal sides are smoothly curved and nearly subparallel in the anterior half. Large specimens of the species are also similar to small specimens of O. schwarzi. In O. schwarzi the microsculpture of the pronotum is isodiametric, whereas in O. debilis it is more longitudinal.

In O. eggersi, the outer edge of the apical lobe of the aedeagus is sinuate ending in an acute apex, whereas in O. humicola it is evenly curved ending in an obtuse apex. O. eggersi also resembles O. carinicollis from the remaining-speciesgroup, but O. carinicollis has a distinctly digitate protibia, it is slightly smaller and the punctation of the pronotum is slightly finer. O. eggersi seems to be variable concerning the punctation of the pronotum and the number of sensillae on the apical lobe of the aedeagus. The specimens from Jamaica show a denser pronotal punctation than the specimens from Cuba, St. Thomas, and the Dominican Republic and only two instead of three apical sensillae.</p> <p>Description: Length: 3.7 – 3.8 mm.

Hespenheide (KNHM).</p> <p>Diagnosis: O. exiguus is one of the smallest species of the genus and darker in colour than the other small species, i.e. O. coruscus. In O. exiguus the head is dark brown in cotrast to the light brown remaining body, whereas O. coruscus is totally yellow to light brown. In contrast to O. coruscus, the apical margin of the clypeus is even and angles without granules. The species also resembles O. indescriptus and without dissecting of the aedeagus the two species cannot be certainly identified. The punctation of the pronotum in O. indescriptus is slightly deeper and denser than in O. exiguus and colouration is darker. The aedeagus of O. indescriptus has a thick, nearly triangular apical lobe, whereas the apical lobe of O. exiguus is slender.</p> <p>Description: Length: 2.5 mm.

It can be separated by the less dense punctation of the fore-head and mainly by the shape of the aedeagus. In O. eggersi, the punctation of the fore-head is as dense as on the vertex. In O. humicola, the punctation of the forehead is distinctly sparser than on the vertex. The apical lobe of the aedeagus of O. humicola is evenly curved on outer edge and the apex is obtuse, whereas in O. eggersi the outer edge of the apical lobe is sinuate and the apex is acute.

Flohr (syntypes of O. munus in BMNH).</p> <p>Diagnosis: The species resembles O. brevicornis, O. rugipennis and O. neotropicus due to the structure and punctation of the pronotum. It can be easily distinguished from those species by the long antennae with elongate second and third antennomere. In contrast to O. latipes, O. rugipennis and O. brevicornis, O. neotropicus has a digitate protibia. It can be also confused with O. mexicanus and O. cordovensis, but O. latipes has an extremely fine netlike microsculpture that is absent in the other two species. The two syntypes of O. latipes are damaged. I selected the smaller one as lectotype. It seems that both type specimens are not conspecific.</p> <p>Description: Length: 6.6 mm. Colouration: Dark red; pronotum and elytra lighter red; legs and antennae yellow. Head: 0.90 mm long, 1.35 mm wide; eyes slightly prominent; as long as temples; vertex densely and deeply punctate; on average, interstices between punctures half as wide as diameter of punctures; wide midline with sparser punctation or partly impunctate; area at base of antennae impunctate and without microsculpture; surface polished; surface of vertex with distinct netlike microsculpture; slightly shiny; supraocular area densely covered by striae and granulate punctures.</p> <p>Antennae with second antennomere oblong; distinctly longer than wide and as long as conical third; following three antennomeres quadrate and as wide as preceding two antennomeres; antennomeres 7 to 10 distinctly wider than preceding antennomeres, but still more or less quadrate.</p> <p>Pronotum: 1.30 mm long, 1.40 mm wide; widest at anterior angles; approximately parallel in anterior half; distinctly convergent in posterior half; at posterior edge approximately half as wide as at anterior edge; lateral and posterior margin fine; with irregular and dense setiferous punctation; longitudinal row of 8 to 10 punctures on each side of wide impunctate midline; on average, interstices between lateral punctures as wide as diameter of punctures or slightly shorter; with few areas more sparsely punctate; anterior edge without margin, but with transverse row of dense punctures; surface with extremely weak netlike microsculpture; nearly polished.</p> <p>Elytra: 1.50 mm long, 1.40 mm wide; with dense and distinct coriaceous ground-sculpture; irregular rows of punctures hardly visible between ground-sculpture.</p> <p>Abdomen with dense setiferous punctation, setae much longer than setae on pronotum; surface with distinct netlike microsculpture.</p> <p>Protibia: 0.56 mm long, 0.20 mm wide; 10 spines at outer edge; apical spines not inserted on digits; WLR: 4.0; in posterior aspect, comb of inner emargination partly covered in middle; posterior face densely covered by moderately long setae.</p> <p>Aedeagus with long apical lobe and acute apex; without sensillae at inner edge.</p></div> 	http://treatment.plazi.org/id/E01A87D0FFE7FFEE4DB4FDDDFBB8FCA6	Public Domain	No known copyright restrictions apply.

J.S. Ashe &amp; R.A. Leschen, #519 (KNHM).</p> <p>Diagnosis: O. majusculus is one of the largest species in the O.-s. str.-group. It is characterised by the wide lateral margin at the posterior pronotal angles. In the similarly sized O. parcus the lateral pronotal margin is narrow. A slightly widened lateral pronotal margin is also found in O. fumarius and O. caliginosus, but these species are smaller and the pronotal sides are more deeply sinuate.</p> <p>Description: Length: 6.7 mm. Colouration: Black; elytra reddish brown; legs dark brown; antennae lighter brown.</p> <p>Head: 0.91 mm long, 1.40 mm wide; eyes slightly prominent; as long as temples; fore-head deeply emarginate; sides of clypeus nearly parallel; anterior edge of clypeus slightly sinuate with acute angles shortly produced; setiferous punctation sparse and moderately deep; irregular midline and moderately large area at base of antennae impunctate; punctation of clypeus sparser than on vertex; interstices between punctures wider than diameter of punctures; punctation of vertex irregular; on average, interstices between punctures as wide as diameter of punctures; on supraocular area punctation still denser and partly granulate; isodiametric microsculpture dense and distinct; surface matt.</p> <p>Antennae slightly longer than head; second antennomere oval; third conical and as long as second; antennomeres four to six as wide as third, but quadrate; following antennomeres wider than preceding antennomeres and also quadrate; last antennomere elongate.</p> <p>Pronotum: 1.40 mm long, 1.53 mm wide; widest near anterior angles; evenly narrowed to posterior angles; slight emargination in posterior half; posterior angles approximately rectangular; lateral margin fine in anterior half, slightly wider in posterior half; shortly in front of posterior angles widened; in dorsal aspect, covered close to anterior angles; setiferous punctation dense and deep with narrow impunctate midline; on average, interstices between punctures slightly wider than diameter of punctures; isodiametric microsculpture deep; surfcae matt.</p> <p>Elytra: 1.74 mm long, 1.65 mm wide; nearly parallel; setiferous punctation distinct; coriaceous ground-sculpture weak; punctures finer and sparser than on pronotum.

A.R Gillogly (KNHM).</p> <p>Diagnosis: O. schwarzi resembles O. neotropicus, O. opacus and O. opacinotus in size. It can be differentiated from O. opacus by the absence of the distinct microsculpture of the pronotum and from O. opacinotus by the less digitate protibia and the shorter second and third antennomeres that are as long as wide in O. schwarzi, but distinctly longer than wide in O. opacinotus. O. schwarzi highly resembles O. neotropicus, because the antennal structure, the shape and microsculpture of the pronotum and elytra are similar. But O. schwarzi clearly differs by the absence of the protibial digits. Additionally, the pronotal punctation is denser in O. schwarzi than in O. neotropicus and the apical lobe of the aedeagus is long and angulate, whereas it is nearly straight in O. neotropicus.</p> <p>Description: Length: 5.6 – 6.3 mm.

In this respect, it resembles O. fumarius and O. caliginosus, but these species are larger and the pronotal emargination is much deeper. Additionally, the shortly produced teeth at the outer angles of the clypeus are absent in O. fumarius and O. caliginosus.</p> <p>Description: Length: 6.3 mm. Colouration: Black, legs and antennae brown.</p> <p>Head: 0.90 mm long, 1.30 mm wide; eyes not prominent; as long as temples; sides of fore-head deeply sinuate; anterior angles of clypeus produced to short acute teeth; anterior edge of clypeus between lateral teeth even; setiferous punctation moderately dense and deep; density of punctation irregular; on average, interstices between punctures two to three times as wide as diameter of punctures; large area at base of antennae, small area on posterior vertex, and transverse area on posterior vertex impunctate; yellow setae hardly reaching adjacent puncture; supraocular and postoculare area with granulate punctures and short striae; distinct netlike microsculpture; surface matt.</p> <p>Antennae shortly longer than head; second antennomere elongate and oval, slightly longer than conical third; following three antennomeres not wider than preceding antennomeres, but approximately quadrate, antennomeres 7 to 10 distinctly wider than preceding antennomeres, but also quadrate.</p> <p>Pronotum: 1.16 mm long, 1.30 mm wide; widest at anterior angles; evenly narrowed to posterior angles; posterior angles obtusely rounded; lateral margin fine; slightly widened to posterior angles; in dorsal aspect, not visible close to anterior angles; setiferous punctation deep and moderately dense; impunctate midline widened posteriad; on average, interstices between punctures twice as wide as diameter of punctures; yellow setae short; shorter than diameter of punctures and interstice between punctures combined; between normal coarse punctures with micro-punctation; distinct netlike microsculpture; surface matt.</p> <p>Elytra: 1.50 mm long, 1.44 mm wide; setiferous punctation moderately deep and dense; in irregular rows; coriaceous ground-sculpture weak; setae as short as on pronotum.</p> <p>Abdomen with dense setiferous punctation; setae distinctly longer than on fore-body; netlike microsculpture distinct; surface matt; lateral punctures on tergite VII with striae.</p> <p>Protibia: 0.66 mm long, 0.23 mm wide; 9 spines on outer edge; apical spines inserted on short digits; WLR: 1.47; in posterior aspect, comb of inner emargination visible throughout its total length; posterior face densely covered with long yellow setae.</p> <p>Aedaegus angulate in nearly rectangular angle; basal lobe longer than apical lobe; apex obtuse; on inner edge with numerous sensillae.</p> <p>Etymology: The specific name honours one of the collectors of the species, Dr. M.

R. Leschen (KNHM, UIC).</p> <p>Diagnosis: Among the species of similar size, O. acutus is characterised by the fine punctation of the pronotum, the long acute anterior angles of the pronotum, and the digitate outer edge of the protibia. A similarly digitate outer edge of the protibia is also found in O. longipunctatus and O. guiananus of the O.-guianus -group. But, in these two species the punctation is much coarser and the shape of the pronotum is more trapezoidal, whereas it is smoothly curved in O. acutus. Within the group of the remaining species, O. digitatus has a similarly deep digitate protibia, but the species is smaller with 3.8 mm than O. acutus with 5.1 mm.</p> <p>Description: Length: 5.1 mm.

R. Leschen (KNHM).</p> <p>Diagnosis: The dense and deep punctation of the pronotum and the elytra of O. carninicollis is similar as in O. eggersi, but O. carinicollis is smaller and has a digitate protibia. The sides of the pronotum are slightly more evenly convergent to the posterior angles. The elytra of O. carinicollis are slightly longer than wide, but quadrate in O. eggersi. The apical lobe of the aedeagus is smoothly curved to an acute apex, whereas in O. eggersi the apical lobe is thicker and dorsally slightly emarginate. The species seems to be variable in size and shape of the aedeagus. In some specimens the apical lobe is slightly more curved than in others.</p> <p>Description: Length: 3.0 – 3.5 mm.

Bernhauer (1933) differentiated also O. lynchi based on a weaker microsculpture of the pronotum and red elytra. However, I cannot find any difference in the microsculpture and the red elytra can be referred to the damaged status of the O. lynchi holotype. The aedeagi are also identical in the two male type specimens.</p> <p>Description: Length: 5.9 mm.

Brooks (UIC).</p> <p>Diagnosis: The species shows a high variability concerning the shape and microsculpture of the pronotum. The acute prominent anterior angles range from very short to extremely long. In the last case, the anterior edge of the pronotum seems to be distinctly emarginate. The microsculpture also varies from deep netlike or isodiametric with matt surface to weak netlike with micro-punctation between the normally setiferous punctation and slightly shiny surface. The species resembles O. schwarzi in size and microsculpture of the pronotum, but O. schwarzi shows only a slight variability in the microsculpture and has no digitate protibia. The shape of the pronotum slightly differs from O. schwarzi. In O. opacinotus, the sides are evenly convergent to posterior angles, whereas in O. schwarzi the curve of sides is more convex. In particular, the posterior angles of O. schwarzi are evenly rounded, whereas in O. opacinotus the pronotal shape is trapezoidal.</p> <p>Description: Length: 6.8 mm.

R. Leschen (KNHM); Huanuco, Panguana (74°56'W, 9°37"S), cut forest, female, 3.8.1975, leg. W. Hanagarth (UIC).</p> <p>Diagnosis: The species is characterised by the iridescent shine of the head and the digitate protibia. Other species with iridescent shine are smaller and have no digitate protibia. Similarly large species with digitate protibia, e.g. O. lescheni, have no iridescent shine on the head. The thick apical lobe of the aedeagus narrowed abruptly to the acute apex. In ventral aspect, the aedeagus resembles that of O. lescheni and O. loreti, since the circular basal lobe is much thicker than the apical lobe. In the male specimen from Peru, the apical lobe is thicker than in the Central Amazon or Trinidad males, but this may be within the range of the species.</p> <p>Description: Length: 4.5 mm.
