“…However, the high altitude montane habitat where Lophorrhinidesmuellerae occurs may suggest a life cycle with a very short life span at the adult stage. This has been shown repeatedly with other genera, particularly in mountainous and/or semiarid environments in southern Africa (e.g., Holm and Marais 1992, Perissinotto et al 1999, Perissinotto 2017). Here the adults of most cetoniine species emerge from their underground cocoons only after major rainfall events in the late spring or summer and fly and mate during the hottest part of the day.…”

“…As in previous work, the description of morphological characters of this study follows the terminology used by Krikken (1984) and Holm and Marais (1992). Specimen total length and maximum width were measured using a Vernier calliper, from the anterior margin of the clypeus to the apex of the pygidium and at the widest point of the elytra, respectively.…”

A male cetoniine specimen recently submitted for identification from the Ditsong Museum of Natural History (Pretoria, South Africa) has been found to represent a yet unknown species. A review of the recently published book of Beinhundner (2017) has further revealed that one of the specimens mistakenly figured as Lophorrhinadonckieri Bourgoin, 1913 in that work is most likely the female of this new species. Analysis of the diagnostic characters of the genus Lophorrhina Westwood, 1842 shows that the new species differs in several key areas. In particular, the clypeal armature is virtually identical in both sexes, the male protibiae are not typically elongate and narrow as in all the members of Lophorrhina, but are remarkably more robust, laterally expanded and with a tridentate margin in both sexes, even though the third tooth in the female and the second and third teeth in the male are virtually obsolete. The general body shape in the new species is also more globose and lacks the typical deplanate and apically tapering elytra of the Lophorrhina males. These and other characters are, in our view, sufficient to justify the erection of a new genus, Lophorrhinidesgen. n., to accommodate the new species, here described as L.muelleraesp. n. The new genus is presumably a mountain specialist, as both known specimens were collected in the southern highlands of Tanzania, at Manow and Rungwe respectively.

“…The holotype and only known specimen for this new species was submitted by Ms Ruth Müller of the Ditsong National Museum of Natural History (Pretoria, South Africa) for identification, as part of a loan to the author of several cetoniine specimens which are currently under review. The usual terminology of Krikken (1984) and Holm and Marais (1992) is followed in this study for the description of morphological characters. Specimen total length and maximum width were measured using a Vernier calliper, from the anterior margin of the clypeus to the apex of the pygidium and at the widest point of the elytra, respectively.…”

Description of Callophylla macrocephala sp. n. from southern Tanzania

A male cetoniine specimen from the old Schürhoff collection currently deposited in the Ditsong National Museum of Natural History (Pretoria, South Africa), was recently submitted for identification and has been found to represent a yet undescribed species of the poorly-known genus Callophylla Moser, 1916. The species is named C.macrocephalasp. n., in recognition of its wider than average head, particularly at the level of the clypeus, and originates from the southern Tanzanian highlands, near the Tanzania-Zambia border town of Nakonde. This brings the total number of species now known for this genus to four, two from West Africa and two from East-Central Africa. All species were described on the basis of a male only, or this and a few extra specimens. The female is only known for the two West African species, C.costata Moser, 1916 and C.lamottei Antoine, 2007. A dichotomous key for the identification of the species of this genus is presented for the first time. It is suggested that the genus may be constituted of high altitude specialists, with a short period of activity and no ability to feed at the adult stage.

“…The genus Rhinocoeta Burmeister, 1842 currently includes two subgenera, the nominal one with five recognised species and R. (Haematonotus) Kraatz, 1880 with three species (Holm and Marais 1992, Beinhundner 2017). On the basis of adult and larval morphology, it has been argued that the genus may phylogenetically be placed close to the subtribe Xiphoscelidina rather than the Cetoniina, and that it constitutes part of a relict lineage derived directly from the most primitive Cetoniinae (Krikken 1984, Holm 1992, Smith et al 1998).…”

Description of a new species of Rhinocoeta Burmeister, 1842 (Scarabaeidae, Cetoniinae) from the South African Northern Cape

Rhinocoetanamaquasp. nov. is recognised as a separate species from its closest relative, R.cornuta (Fabricius, 1781) after a review and close analysis of specimens recently collected in the semiarid region of the Northern Cape Province, South Africa. The new species can be readily separated from R.cornuta by the drastically reduced tubercle and associated depression on its anterior pronotal margin, particularly in the male. In addition, the general body shape of R.namaqua is more globose than that of R.cornuta, its average total length is larger, and its elytral costae are generally reduced and poorly visible, particularly at the level of the umbones. These characteristics make it practically impossible to separate the two sexes of R.namaqua, without inspection of the internal reproductive organs, as their external morphologies are virtually identical, unlike in R.cornuta. Finally, the aedeagal parameres of R.namaqua exhibit a narrower apex than those of R.cornuta and, in particular, lack the subapical hook-shaped lateral expansions that are so typical of all the other Rhinocoeta s. str. species. The new species appears to be restricted to specific bioregions of the Succulent and Nama Karoo biomes of the Northern Cape, and like all other species of the genus is generally found on or under mammal herbivore dung. Adult activity is limited to short periods immediately after rainfall events, during which individuals fly around and mate, but do not feed on either fruits or flowers.
