Type locality. Unspecified.
Diagnosis. Pronotum rather glossy (Fig. 62); FLP sclerite subapicodorsal lobe short anteriorly (Figs. 156– 157); right lateral fold produced into a longitudinal spoon-shape process with apical portion open ventrally, ventral edge bordered with a conspicuous brush of villi (Fig. 185A), lacking well-sclerotized projection on apicoventral edge (Fig. 185 B); axial sclerite shorter than subaxial sclerite, acute apically (Fig. 156); subaxial sclerite moderately long and robust (Fig. 153).

Scarabaeus gazella Fabricius: Syntype (ZMUK):  small green square; [ZMUC / 00508509]; [TYPE] red card; [WORLD / SCARAB. / DATABASE / WSD00029479] barcode label; [SYNTYPE ♂ / Scarabaeus / gazella / Fabricius, 1787 / vid. F. Génier, 2016] red card; [Guinea / Isert / Mus. T. Lund / Copris / gazella / ♂ / F.] handwritten [in error] see Nomenclature and taxonomy below for more details. Note. The first label, a small green square without inscription, confirms this specimen as a Fabrician type (Zimsen 1964). The last label was added after Fabricius’s time and is erroneously cited as African. See nomenclature and taxonomy below section for more details. Scarabaeus dorcas Olivier: Neotype♂ (MNHN) present designation: [[[Madagascar]] / Diego-Suarez 7 / Ch. Alluaud, 1893] partly handwritten; [MUSEUM PARIS / MADAGASCAR / COLL. CH.

This neotype designation is made with the express purpose of clarifying the taxonomic status and the type locality of Scarabaeus dorcas Olivier. The specimen designated agrees in morphology to the description presented above. The original type material used for Olivier’s description is lost or destroyed (Olivier Montreuil, MNHN, personal communication). The neotype has been selected to match Olivier’s description and type locality, in addition to possessing the best diagnostic character for the species. The neotype is deposited in the collection of the Museum national d’Histoire naturelle de Paris along with the remains of Olivier’s collection. MAP 9.

Nomenclature and taxonomy. An application was submitted to the International Commission of Zoological Nomenclature on 20 October 2016 (Génier & Krell 2017) and was assigned case number 3722. The application is made to maintain prevailing usage of the species name D. gazella for the widely introduced species through the process of setting aside all previous type fixations for the nominal species Scarabaeus gazella Fabricius and the designation of a neotype. The circumstances with the type material of Scarabaeus gazella are more intricate. In this case we are in presence of three putative syntypes. Unlike the syntypes of S. catta, these three specimens all bear a small green square typical of Fabrician types (Zimsen 1964). There is a well-developed male (10.5 mm), a small male (8.0 mm) with secondary sexual characters resembling a female, and a moderately large female (10.0 mm). The large male and the female bear a handwritten label with the following information: “ Guinea, Isert, Mus. T. Lund, Copris gazella F.” These labels were added at least 14 years after the species was originally described, as the generic name used on these labels is Copris, a genus Fabricius used for the first time in Fabricius (1801). After a careful study of these three specimens, which include the dissection and examination of the internal sac sclerites of the two males, we conclude that this series is a mixture of two species. The large male is a representative of the oriental species D. catta and the small male and female are representative of the West African species D. falciger. At this point, there is no realistic possibility of finding out the true historical details about these specimens. The most likely chain of events is that Fabricius had only the large male specimen lacking geographic information when he described the species in the appendix of the second volume of Mantissa Insectorum published in December 1787 (Evenhuis 1997; Bousquet 2016). The original description is clear: “occipite cornubus duobus arcuatis”, and can only apply to the specimen with two well-developed cephalic horns. We can only speculate on the number of specimens seen by Fabricius at the time of the description. Subsequently, Fabricius had received two additional specimens from Tønder Lund collected in Africa (Guinea), which he identified as his S. gazella and added the new information on the distribution five years later in the Entomologia systematica (Fabricius 1792). The currently recognized synonymy for D. gazella was established by d’Orbigny (1913). The first species listed is Scarabaeus catta Fabricius, the entry is preceded by a question mark indicating that this synonymy is dubious. There is, however, no indication as to why d’Orbigny considered this synonymy dubious. This synonymy is here resolved on the principle of priority and the name D. catta is valid for an oriental species. The second synonym listed is Scarabaeus dorcas Olivier, described from Madagascar. This name is as a synonym of D. gazella assuming that the International Commission on Zoological Nomenclature rules on the conservation of the name D. gazella for the widely introduced species. The third species listed is Copris metallicus Fabricius, described from India. The holotype (by monotypy) of the species has been studied and despite the fact that it is missing the head and prothorax, it can be stated here that it does not belong to the genus Digitonthophagus. It is an Onthophagus of the Onthophagus orientalis species group and most likely belonging to the subgenus Sinonthophagus Kabakov. The species is therefore here removed from synonymy with D. gazella and considered valid with the following combination Onthophagus metallicus (Fabricius). It should be noted here that a junior homonym, Onthophagus metallicus Fåhraeus, exists as a synonym of Proagoderus bicallosus (Klug). The fourth species listed is Copris antilope Fabricius, also described from India. Three syntypes are in ZMUC and an additional specimen in the ZMUK. The examination of the specimens revealed that they do not belong to the genus Digitonthophagus but rather belong to the genus Onthophagus and are similar to Onthophagus (Colobonthophagus) dama (Fabricius). The species is therefore here removed from synonymy with D. gazella and considered valid with the following combination Onthophagus antilope (Fabricius). Again, it should be noted here that a junior homonym, Onthophagus antilope Motschulsky exists, the latter is a synonym of Onthophagus (Palaeonthophagus) vacca Linnaeus. It is beyond the scope of this work to determine if O. antilope is synonymous with O. dama. The fifth name listed as synonyms is Onthophagus intermedius Reiche with a type locality “ Sénégal.” This name was first listed as “ O. gazella var. intermedius Dupont ” a variety of Onthophagus gazella in Dejean (1836) and is a nomen nudum. A specimen of D. sahelicus with a small manuscript label stating “1395” and a second manuscript label stating, “ intermedius Reiche.gazella? Fab. Senegal ” was found in the BMNH collection. It is not clear if this is a specimen acquired from Dupont’s collection by The Natural History Museum of London. Reiche (1840) stated that Dupont, who was a prominent natural history specimen merchant in the 19th century (Cambefort 2006), was the first to use the name O. intermedius for specimens in his collection. The name O. intermedius Reiche is, however, unavailable as it was first published in an available work as a synonym of “ Onthophagus gazella ” (Article 11.6; International Commission on Zoological Nomenclature 1999).
