Revision of the genus Holocephalus (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini)

The genus Holocephalus Hope is revised and now contains five species: H. cristatus (Gillet), H. eridanus (Olivier), H. julieni sp.nov. H. sculptus (Gillet), and H. simoni sp.nov. All taxa are described and illustrated. A key to speies of Holocephalus is included. Lectotypes are designated for H. eridanus and H. sculptus. Scarabaeus eridanus Olivier is designated as the type species for the generic name Atrichius Gillet (a junior synonym of Holocephalus). On révise le genre Holocephalus Hope qui regroupe maintenant cinq es-pèces, soit H. cristatus (Gillet), H. eridanus (Olivier), H. julieni sp.nov., H. sculptus (Gillet) et H. simoni sp.nov. Outre les descriptions et illustrations pour chaque espèces on propose un tableau de détermination pour les espèces maintenant comprises dans le genre Holocephalus. On désigne des lectypes pour H. eridanus et H. sculptus. Enfin, on désigne l’espèce Scarabaeus eridanus Olivier comme type du genre Atrichius Gillet (considéré comme synonymec junior du genre Holocephalus)

Monde 28: 16 (monograph) Type locality. Brésil. Diagnosis. The large size, rather thick body combined with dark metallic blue sheen of the dorsum will separate D. amyntas from all other species. It can easily be separated from its sister species D. attalus by the shape of the clypeal teeth (Fig. xx) and the more slender metatibia. Description. Male lectotype (Fig. 27). Body. Body large, length 18.0 mm, maximum width 10.0 mm; body subrectangular; dorsum narrowly flat. Color. Dorsal surface dark reddish brown to black, glossy, with metallic sheen; head with greenish to coppery metallic sheen adjacent to the eyes; pronotum with blue metallic sheen except for anteromedian carina, on anterior portion of disc and surface adjacent to lateral fossae; elytra with rather faint blue to purple metallic sheen; ventrum light to dark brown; pygidium with blue and green metallic sheen; legs light to dark brown.

Females differs in having the clypeofrontal carina much lower, approximately 4 times as wide as high and by the anterior pronotal carina simply tri-sinuate and only slightly more developed medially. Variation is seen in the extent and intensity of the metallic sheen, as well as the color varying from greenish to dark purplish-blue. In some individuals the pronotal punctures are slightly larger and coarser. Specimens from the cerrado slightly but consistently differs in the shape of the clypeal teeth which are smaller and more obliquely oriented laterally. Females from the cerrado also have the median portion of the pronotal carina produced into an upward angular projection, the carina is simply arcuate in specimens from the Atlantic forest. The configuration of the male median pronotal projection is also variable, some individuals present a simply dorsoventrally flat projection, and in some other the anterior edge of the projection is thickened and more or less marginate dorsally. The inferior surface of the lobate median projection is produced into a more or less sharp longitudinal carina. This carina, which is very blunt and less developed in the Atlantic forest specimens is dividing the anterior concavity into two equal portions. Nomenclature and taxonomy. D. amyntas Lacordaire, 1856 bona species = D. waterhousi Olsoufieff, 1924 (auctores), new synonymy. Lacordaire’s (1856) description and illustration (holotype) of this species were considered invalid by previous authors. The description alone is too vague to identify the species, however the illustration is very accurate and clearly shows one of the diagnostic characters of this species. The clypeal teeth are clearly defined in the drawing and correspond to the species that is found in the cerrado and Atlantic forest of Brazil. This species was redescribed as D. waterhousi by d’Olsoufieff in 1924. Harold (1869) lists Lacordaire’s name but failed to recognize the description as valid, which seems to have started the confusion over the identity of this species.Published as part of François Génier & Patrick Arnaud, 2016, Dendropaemon Perty, 1830: taxonomy, systematics and phylogeny of the morphologically most derived phanaeine genus (Coleoptera: Scarabaeidae, Scarabaeinae, Phanaeini) in Zootaxa 4099 (1) on pages 55-57, DOI: 10.11646/zootaxa.4099.1.1, http://zenodo.org/record/26827

Catharsius harpagus Harold 1877

Catharsius harpagus Harold, 1877 (Figs. 8–12) Catharsius harpagus Harold, 1877: 97 Type locality. Delagoa Bay (Mozambique) Three specimens are in the collection. A male and a female are from recent collecting (1963) and have been seen by M.C. Ferreira. The remaining specimen is a syntype. Harold’s description is clear in stating a length range of “ 22–30 mill.” in the original description excluding the possibility of a unique specimen studied. Harold also stated “Specimina typica in Museo Berolinensi asservantur” for the type deposition. It is possible that the remaining specimens studied by Harold are deposited in different collection(s). Fortunately, the syntype studied is a well-developed male. This specimens is designated as lectotype (present designation) and bears the following labels (Fig. 10): [Delagoa/ Bay] white paper; [72066] white paper; [Type] red card; [D. O. Africa/ 36] red handwriting on white paper; [O.-Afrika/ Delagoa boy/ Felsche] handwriting on blue paper; [SYNTYPUS / Catharsius / harpagus Harold, 1877 / labelled by MNHUB 2014] red card; [LECTOTYPE ♂/ Catharsius / harpagus / Harold, 1877 / dés. F. Génier, 2014] red card. Remark. The male lectotype has been dissected and the aedeagus extracted (Figs. 11–12). This species is currently valid with no synonyms. No change in the taxonomic status of this species is required.Published as part of Génier, François & Josso, Jean-François, 2016, Notes on Afrotropical Catharsius species described by Edgar von Harold (Coleoptera: Scarabaeidae, Scarabaeinae), pp. 333-342 in Zootaxa 4072 (3) on page 335, DOI: 10.11646/zootaxa.4072.3.3, http://zenodo.org/record/26181

Catharsius camillus Harold 1877

Catharsius camillus Harold, 1877 (Figs. 13–17) Catharsius vitulus Boheman, 1857: 223 Catharsius camillus Harold, 1877: 97 Type locality. Cap b. sp. (South Africa) As for C. pandion, the syntypic series consist of seven specimens (4 ♂♂, 3 ♀♀). In order to provide a primary type with the most diagnostic characters a large male is selected from the syntypic series as lectotype (present designation). This specimen bears the following labels (Fig. 15): [Krebs!] handwriting on green card; [Camillus / Harold/ Cap b. sp.] handwriting on green card; [9352] white paper; [Type] red card; [SYNTYPUS / Catharsius / camillus Harold, 1877 / labelled by MNHUB 2014] red card; [LECTOTYPE ♂/ Catharsius / camillus / Harold, 1877 / dés. F. Génier, 2014] red card. Remark. The male lectotype has been dissected and the aedeagus extracted and figured (Fig. 16–17). Catharsius camillus is currently a junior subjective synonym of Catharsius vitulus Boheman, 1857. It should be pointed out that Harold’s original description state Port Natal (=Durban) as the type locality which conflict with the original specimen labels. Because C. camillus is synonymous with C. vitulus, we believe that the proper type locality would be most likely Cap. b. sp., in its former sense which included all of western South Africa. Although inaccurate it would more or less coincide with the southern distribution range of C. vitulus (A. Davis pers. comm.). All 6 paralectotypes bear a “Capland” printed label further supporting this interpretation.Published as part of Génier, François & Josso, Jean-François, 2016, Notes on Afrotropical Catharsius species described by Edgar von Harold (Coleoptera: Scarabaeidae, Scarabaeinae), pp. 333-342 in Zootaxa 4072 (3) on pages 335-338, DOI: 10.11646/zootaxa.4072.3.3, http://zenodo.org/record/26181
