03AC87DDFF8AFF86FCDDC046FC5AD2B0.taxon	description	Description. Holotype. Major male (Figs. 1 – 2). Length: 6.1 mm. Humeral width: 3.4 mm. Weakly shiny, opaque black. Clypeal margin sharply reflexed anteriorly, feebly so laterally; anterior edge faintly emarginate. Clypeal disc with few coarse punctures distributed across width. Frons with scattered shallow punctures. Clypeal disc and frons almost flat and lacking both clypeal and frontal carinae, the latter being poorly developed behind the eyes; surface between punctures finely alutaceous. Genal margin noticeably arcuate laterally, anteriorly forming a distinct, obtuse indentation with the clypeal margin; gena sharply and obtusely angulate posteriorly opposite the pronotal angles; genal surface slightly concave and with scattered, shallow punctures. Small eyes, five facets wide and emarginate, separated by about 16 eye widths. Occiput with scattered shallow punctures. Pronotum (Fig. 13) moderately convex and margined anteriorly and laterally, pronotal protuberance conical broad and evenly arched, weakly projecting over the posterior portion of the head. Pronotal surface distinctly alutaceous and with two sizes of punctures: larger punctures annular with margins sharply defined, centrally with an erect reddish-yellow seta, the large punctures usually separated by approximately one diameter; small secondary punctures half the diameter of large punctures and not as numerous, scattered among large punctures, umbilicate in shape and lacking setae. Elytral striae with feebly shiny and vaguely punctate; intervals opaquely alutaceous with irregular double rows of small shiny tubercles; the base of each tubercle with a fine, reddish-yellow seta. Pygidium slightly longer than broad; opaquely alutaceous, slightly to moderately shiny apex, only slightly convex; covered sparsely with pale yellow setae, interspersed with small shiny punctures. Ventral surfaces, including antennae, black to blackish brown. Metaventrite surface coarsely punctate, more so laterally where the surface between punctures is finely alutaceous; base of metaventrite with large, coarse punctures, each bearing pale yellow setae. Ventrites, except for the first, with a row of setigerous punctures across their basal margin; last segment narrowed medially. Aedeagus like in Figure 19. Lamella copulatrix like in Figure 22. Prothoracic legs greatly elongate, the apices of the profemora extending slightly beyond the pronotal margin; protibiae long, slender, and recurved, with a pronounced apical conical projection and a long yellow pencil of setae protruding above the apical spine; all femora with scattered, coarse punctures, each puncture bears a pale yellow seta. Variation. Length: 4.5 – 6.7 mm. Width: 2.5 – 3.5 mm. The colour of the lateral side and apical border of the elytra can vary from black to reddish brown. Male pronotal protuberance can vary from evenly rounded to slightly notched in the middle. Male minors with pronotum less convex, protibiae with apical projection shorter, profemur barely extending to the lateral pronotal margin. Females differ with clypeus slightly reflexed anteriorly, broadly, somewhat angularly emarginate; clypeal disc coarsely, rugousely punctate, punctures often with brownish-yellow setae; clypeal carina distinct (sometimes absent) but only slightly and rather evenly elevated above clypealfrontal surface. Frons behind carina with a few distinct coarse punctures; frontal carina low but distinct, generally of uniform height; gena scarcely flared, only very obtusely angulate near pronotal angles and with coarse punctures. Area between female clypeal and frontal carina can vary from slightly to heavily and coarsely punctate. Pronotum less convex, pronotal protuberance indicated by a rounded swelling. Pygidium approximately as broad as long. Prothoracic legs stubby and shorter and the apex of the profemur barely reaches the lateral pronotal margin; protibia proportionately shortened; apical projection and pencil of setae lacking; apical spine as long as the three basal tarsomeres. Last ventrite not emarginate, approximately the same width throughout.	en	Arriaga-Jiménez, Alfonsina, Escobar-Hernández, Fernando, Rös, Matthias, Kohlmann, Bert (2020): The establishment of the Onthophagus anthracinus (Coleoptera: Scarabaeidae) species complex and the description of a new species.

03AC87DDFF8AFF86FCDDC046FC5AD2B0.taxon	distribution	Distribution and ecology. This species occurs in Oaxaca, Mexico (Fig. 5) at Reserva Comunitaria San Pablo Etla (Sierra Norte), 1900 – 3000 m; San José del Pacífico, San Mateo Río Hondo and south of Juchatengo (Sierra Sur), 1800 – 2500 m; Sierra Mixe at Zempoaltépetl, Santa María Tlahuitoltepec, and Santa María Yacochi, from 2400 – 2600 m. It has been collected in acahual (abandoned agricultural fields undergoing regeneration), grassland, cloud forest, Quercus Linnaeus (Fagaceae) forests, and Pinus - Quercus forest (Pinus Linnaeus, Pinaceae) and seems to be more abundant in Quercus forests. Specimens have been collected using dung-baited and carrion-baited pitfall traps, by hand, and in cattle (Bos taurus Linnaeus, 1758; Artiodactyla: Bovidae) and horse (Equus caballus Linnaeus, 1758; Perissodactyla: Equidae) manure. Taxonomic placement. Onthophagus etlaensis belongs to the O. anthracinus species complex, part of the O. landolti species group. This species has many similarities to O. anthracinus. Onthophagus etlaensis has larger pronotal punctures (75 μm), separated by at least one diameter, pronotum traverse along its middle longitudinally by an evident sulcus in major males and the pronotal area around it convex; whereas, O. anthracinus has smaller pronotal punctures (50 μm) separated by 1 – 2 diameters, pronotal midline well marked in major males and the pronotal area around it flattened and forming a rhombus. The pygidium of O. etlaensis is opaquely alutaceous and is slightly to moderately shiny, much less so than in O. alluvius or O. durangoensis. The aedeagus has been studied for this species complex (Figs. 16 – 20). All species north of the Isthmus of Tehuantepec, including O. etlaensis, have an evident ring near the base of the aedeagus. On the contrary, O. anthracinus has a poorly developed and indistinct ring at the phallobase (Fig. 17). There are also fine differences in the structure of the parameres separating O. etlaensis from O. anthracinus; the first species has a straight frontal margin of the parameres as seen in lateral view, whereas the second species has a curved margin (Figs. 17, 19); the first species has a slender apex of the parameres as seen in the lateral view, whereas the second species has a much broader apex (Fig. 1). The lamella copulatrix of the internal sac (Figs. 21 – 22) is very similar in both species. These characteristics hold true for the populations examined from O. anthracinus originating from Chiapas (Mexico), Guatemala, and Costa Rica. As Howden and Cartwright (1963) observed, the type of punctures is one of the main characters for separating the different species. The Oaxacan specimens are constant in having large punctures (75 μm), whereas the specimens studied from Chiapas to Costa Rica have consistently smaller (50 μm) punctures. It seems likely that Bates (1887: 77) in his redescription of O. anthracinus included specimens of O. etlaensis, as he indicated Oaxaca and Juquila as distribution localities. Habitat affinities. Onthophagus etlaensis occupies similar ecological niches to O. anthracinus: Quercus, Pinus - Quercus, and Pinus forests in mountainous regions (Fig. 6).	en	Arriaga-Jiménez, Alfonsina, Escobar-Hernández, Fernando, Rös, Matthias, Kohlmann, Bert (2020): The establishment of the Onthophagus anthracinus (Coleoptera: Scarabaeidae) species complex and the description of a new species.

03AC87DDFF81FF87FC3CC271FDCBD008.taxon	description	The International Commission on Zoological Nomenclature (1999) (Article 23.9.5) states that “ When an author discovers that a species-group name in use is a junior primary homonym (Article 53.3) of another species group name also in use, but the names apply to taxa not considered congeneric after 1899, the author must not automatically replace the junior homonym; the case should be referred to the Commission for a ruling under the plenary power and meanwhile prevailing usage of both names is to be maintained [Art. 82]. ” This Article also indicates that the senior homonym should be in use, which is not the case with Faldermann’ s name. O. anthracinus Harold, 1873 is a junior primary homonym that is currently in use and has not been considered congeneric with its senior homonym after 1899. So, although Faldermann’ s name is not in use, one can interpret the spirit of the Article as to preserve the usage of junior primary homonyms that have been in use, by not being considered congeneric as its senior homonym for a long time. One can consider that this does not violate the principle that no two taxa should share the same name; therefore, we do here maintain the use of O. anthracinus Harold as a valid name. We have submitted a case to the International Commission on Zoological Nomenclature as directed in Article 23.9.5 for the conservation of the specific name Onthophagus anthracinus Harold, 1873 and it is presently under review as case number 3807. Onthophagus anthracinus (Figs. 3 – 4, 14, 17, 21) is known to occur from Chiapas, Mexico to Chiriquí, Panama. We cite here localities that were studied for the present analysis. Mexico, Chiapas: 5 km W San Cristóbal de las Casas, 8000 ’, 13 – 16. viii. 1969, pine-oak forest, S. J. Peck (one male, eight females); 3 miles NW San Cristóbal de las Casas, 29. v. 1969, H. F.

03AC87DDFF80FF80FCDDC597FDB1D277.taxon	description	In their catalogue of the Onthophagini of the Western Hemisphere, Pulido Herrera and Zunino (2007) placed O. mextexus Howden and Cartwright, 1970 in synonymy with O. durangoensis Balthasar, 1939. However, O. mextexus is reported to be distributed from Texas, United States of America to Puebla, Mexico, and therefore does not match the toponymy given by Balthasar (1939) of Durango. Moreover, the description of O. durangoensis is clear that it has an apically shiny and punctate pygidium with the rest of the surface alutaceus and nearly impunctate (Balthasar 1939: 45 – 46). These are one of the main characteristics given by Howden and Cartwright (1963) to differentiate O. knulli Howden and Cartwright, 1963 from O. mextexus. It would seem, therefore, that Pulido Herrera and Zunino (2007) confused O. knulli with O. mextexus, establishing an incorrect synonymy. The two specimens (male and female) Balthasar (1939) used for his original description carry labels reporting the type locality as Canelas, Durango (Bezděk and Hájek 2013). Balthasar (1939) also made the comment that his new species probably pertained to group 8, as established by Boucomont (1932). A photographic comparison of the types of O. durangoensis (Figs. 12, 15, 18) (taken by Jiří Hájek), with O. knulli and O. monticolus (taken by Serge Laplante), confirms without doubt that O. mextexus is a valid species and not a synonym of O. durangoensis, as erroneously established by Pulido Herrera and Zunino (2007). It also revealed that O. durangoensis and O. knulli are conspecific, based on the pronotal puncture pattern seen in the photographic analysis. Therefore, we correct this error and establish the following new synonymy: O. knulli Howden and Cartwright, 1963 = O. durangoensis Balthasar, 1939. This species has been reported for Arizona and New Mexico in the United States of America and Durango, Jalisco, Colima, Michoacán, Morelos, Federal District, and Oaxaca in Mexico. It is here reported for the first time for Sinaloa, Mexico based on three female specimens from Copala, 7. vii. 1968, Halffter, Martínez, Reyes (Instituto de Ecología, Xalapa collection). The presence of O. durangoensis in Oaxaca merits confirmation, because intensive collecting by A. A. - J. in this state over the last years has not produced any specimens of this taxon. Martínez-Falcón et al. (2018) report it (as O. knulli) for the Juniperus Linnaeus (Cupressaceae) forests of the state of Hidalgo, Mexico. This is probably an identification error; O. mextexus and O. alluvius have been reported for this state (Delgado and Márquez 2006).	en	Arriaga-Jiménez, Alfonsina, Escobar-Hernández, Fernando, Rös, Matthias, Kohlmann, Bert (2020): The establishment of the Onthophagus anthracinus (Coleoptera: Scarabaeidae) species complex and the description of a new species.

03AC87DDFF87FF80FC3CC5ACFC56D728.taxon	description	We establish the O. anthracinus species complex as having the following characteristics: anterior edge of pronotal punctures lacking tubercles; pygidial punctures very shallow, at least in basal half, sometimes deep and distinct if apical half of pygidium is shiny; male with pronotal protuberance; female with protuberance usually feebly indicated; pronotal punctures not crowded, separated by at least one diameter, anterior edge of pronotal punctures lacking any small shiny tubercle; surface dull, alutaceous, brown or black; length less than 7.5 mm.	en	Arriaga-Jiménez, Alfonsina, Escobar-Hernández, Fernando, Rös, Matthias, Kohlmann, Bert (2020): The establishment of the Onthophagus anthracinus (Coleoptera: Scarabaeidae) species complex and the description of a new species.

03AC87DDFF87FF80FC3CC774FEDFD01C.taxon	description	As previously mentioned, Pulido Herrera and Zunino (2007) erroneously established the following synonymy: O. mextexus Howden and Cartwright, 1970 (replacement name for O. monticolus Howden and Cartwright 1963) = O. durangoensis Balthasar. Onthophagus mextexus is here resurrected as a valid species. This species has received recent attention (Huerta Crespo and Cruz Rosales 2016; Huerta Crespo et al. 2016; Halffter et al. 2018) as an important component for sustainable tropical cattle ranching in the State of Veracruz, Mexico. It is found in cloud, Quercus, Pinus - Quercus forests, secondary vegetation, shaded plantations, and paddocks. It can be found in moderately technified ranches that are surrounded by forests. The species is known to occur in Texas in the United States of America and Nuevo León, Hidalgo, Puebla, Guanajuato, and Veracruz in Mexico. It is here reported for the first time for San Luis Potosí based on one male and seven female specimens from 20 km W Xilitla, 1600 m, 12. vi – 6. viii. 1983, cloud forest, flight interception trap, S. and J. Peck (Canadian Museum of Nature collection).	en	Arriaga-Jiménez, Alfonsina, Escobar-Hernández, Fernando, Rös, Matthias, Kohlmann, Bert (2020): The establishment of the Onthophagus anthracinus (Coleoptera: Scarabaeidae) species complex and the description of a new species.

03AC87DDFF86FF81FCDDC551FE94D5B7.taxon	description	Boucomont (1932) published a synopsis of the Neotropical Onthophagus. In this work, he established what he called the “ 8 th group ” of Onthophagus, encompassing the species of what is now called the O. landolti species group: O. anthracinus Harold, 1873, O. arizonensis Schaeffer, 1909, O. atrosericeus Boucomont, 1932, O. chryses Bates, 1887, O. columbianus Boucomont, 1932, O. cribricollis Horn, 1881, O. igualensis Bates, 1887, O. iodiellus Bates, 1887, O. hoepfneri Harold, 1869, O. landolti Harold, 1880, O. lecontei Harold, 1871, O. longimanus Bates, 1887, and O. rufescens Bates, 1887. Later, Zunino and Halffter (1997) redefined this group and renamed it the O. landolti species group and added: O. aciculatulus Blatcheley, 1928, O. alluvius Howden and Cartwright, 1963, O. brachypterus Zunino and Halffter, 1997, O. digitifer Boucomont, 1932, O. knausi Brown, 1927, O. knulli Howden and Cartwright, 1963, O. lebasi Boucomont, 1932, O. mariozuninoi Delgado, Navarrte and Blackaller, 1993, O. mextexus Howden and Cartwright, 1970, O. schaefferi Howden and Cartwright, 1963, O. subopacus Robinson, O. tuberculifrons Harold, 1871, and O. zapotecus Zunino and Halffter, 1988. Subsequently, Howden and Génier (2004) incorporated the following species to the O. landolti species group: O. altivagans Howden and Génier, 2004, O. canelasensis Howden and Génier, 2004, O. dubitabilis Howden and Génier, 2004, O. gibsoni Howden and Génier, 2004, and O. pedester Howden and Génier, 2004 and established the O. lecontei – O. subopacus species complex. Recently, Moctezuma et al. (2016) described another species for the O. landolti species group, O. martinpierai Moctezuma, Rossini, Zunino, Halffter, 2016. They also established another species complex consisting of O. martinpierai, O. mariozuninoi, and O. dubitabilis. We present below an updated list of the species belonging to the O. landolti species group, including three species complexes, the O. lecontei – O. subopacus species complex as defined by Howden and Génier (2004), the O. mariozuninoi species complex as defined by Moctezuma et al. (2016), and the O. anthracinus species complex as defined in this paper. Onthophagus columbianus Boucomont, 1932 drops from this list because it was recently placed in junior synonymy with Onthophagus elegans Klug, 1832, a Madagascan species (Rossini and Vaz-de-Mello 2016).	en	Arriaga-Jiménez, Alfonsina, Escobar-Hernández, Fernando, Rös, Matthias, Kohlmann, Bert (2020): The establishment of the Onthophagus anthracinus (Coleoptera: Scarabaeidae) species complex and the description of a new species.
