Lophorrhinidesmuellerae (Coleoptera, Scarabaeidae, Cetoniinae): a new genus and species from southern Tanzania.

ABSTRACT: 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, Lophorrhinides gen. n., to accommodate the new species, here described as L.muellerae sp. 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.

New species of Eriopeltastes Burmeister & Schaum, 1840 (Coleoptera, Scarabaeidae, Cetoniinae, Trichiini) from South Africa.

Project description:Both male and female of a new species of Eriopeltasttes Burmeister & Schaum, 1840, E. (E.) ornatus Ricchiardi, sp. n., are described from the mistbelt grassland of KwaZulu-Natal. Sexual dimorphism is extreme in this genus, with females being brachypterous, fossorial and entirely black to dark brown in general body colour. This is only the fifth out of 12 known species in this genus for which the female is known. The species appears to be restricted to areas within or in the immediate vicinities of two marginal nature reserves, Karkloof and Blinkwater, in a grassland habitat that is regarded as one of the most threatened in the Province of KwaZulu-Natal. Despite its acknowledged importance as centre of endemism the area is currently in a precarious state of large-scale degradation.

New species of Xiphoscelis Burmeister, 1842 (Coleoptera, Scarabaeidae, Cetoniinae) from arid regions of South Africa and Namibia.

Project description:Two new species of the southern African genus Xiphoscelis Burmeister, 1842 are recognised and described, X. braunsi sp. nov. from the Eastern and Western Cape Karoo (South Africa) and X. namibica sp. nov. from the Huns Mountains of southern Namibia and adjacent ranges in South Africa. These were previously overlooked and grouped together with X. schuckardi Burmeister, 1842, but further material and more in-depth analyses have now revealed their clear separation on the basis of key diagnostic features, including clypeal structure, metatibial spur development and aedeagal shape. The densely and coarsely costate elytral structure and the black to brown colour of these species are symplesiomorphies shared with a number of the most primitive genera among the African Cetoniinae. However, these characters also reflect the convergent adaptation to hot and arid conditions they share with several other species occurring in this region. Phylogenetic relationships of the genus with other Cetoniinae are explored using the larval characters highlighted in the description of the 3rd instar larva of X. braunsi sp. nov. The extraordinary hypertrophy observed in the male metatibial spur of species in this genus, and particularly in X. schuckardi, appears to represent a defence mechanism against potential predators on the ground, apart from playing a role during mating.

Molecular phylogeny of the genus Dicronocephalus (Coleoptera, Scarabaeidae, Cetoniinae) based on mtCOI and 16S rRNA genes.

Project description:The seven species belonging to the genus Dicronocephalus are a very interesting group with a unique appearance and distinct sexual dimorphism. Only one species among them, Dicronocephalusadamsi, has been known in the Korean fauna. This species is recognized as having a wide distribution from Tibet to Korean Peninsula and is currently represented by two subspecies that have separated geographical ranges. The phylogenetic relationships of Dicronocephalusadamsi were still unclear. The phylogeny of Dicronocephalus is reconstructed with a phylogenetic study of five species including four subspecies based on a molecular approach using mitochondrial COI and 16S rRNA genes. Our results are compared with the results obtained by previous authors based on morphological characters. They show that the tested taxa are divided into two major clades. Clade A consists of two species (Dicronocephalusadamsi + Dicranocephalusyui) and Clade B includes the others (Dicronocephalusdabryi + Dicranocephalusuenoi + Dicranocephaluswallichii). This result generally supports Kurosawa's proposal except that Dicronocephalusdabryi and Dicranocephalusuenoi are newly recognized as members of a monophyletic group. We propose that Dicronocephalusadamsidrumonti is a junior subjective synonym of Dicronocephalusadamsiadamsi. These results show that three members of the Dicranocephaluswallichii group should be treated as species rather than subspecies. However, further research including analyses of different genetic markers is needed to reconfirm our results.

Five new species of Trigonopeltastes Burmeister and Schaum from Central America with new country records for other New World Trichiini (Coleoptera, Scarabaeidae, Cetoniinae).

Project description:Five new species of Trigonopeltastes Burmeister and Schaum, 1840 are described: Trigonopeltastes arborfloricola sp. n. from Nicaragua, Trigonopeltastes formidulosus sp. n. from Costa Rica, Trigonopeltastes henryi sp. n. from Costa Rica, Trigonopeltastes mombachoensis sp. n. from Nicaragua, and Trigonopeltastes warneri sp. n. from Belize and Guatemala. An updated key to species of Trigonopeltastes is presented. Trigonopeltastes nigrinus Bates, 1889 and Trigonopeltastes carus Bates, 1889 are placed in synonymy with Trigonopeltastes geometricus Schaum, 1841, syn. n.. The males of Trigonopeltastes aurovelutinus Curoe, 2011 and Trigonopeltastes simplex Bates, 1889 are described for the first time. New country records are given for the following: Giesbertiolus ornatus Howden, 1988: Costa Rica; Paragnorimus sambucus Howden, 1970: Guatemala; Trichiotinus bibens (Fabricius, 1775): Canada; Trigonopeltastes archimedes Schaum, 1841: Guatemala and Costa Rica; Trigonopeltastes frontalis Bates, 1889: Belize, Guatemala, and Honduras; Trigonopeltastes glabellus Howden, 1988: Guatemala; Trigonopeltastes geometricus Schaum, 1841: Honduras; Trigonopeltastes sallaei sallaei Bates, 1889: Guatemala and Honduras; Trigonopeltastes simplex Bates, 1889: Mexico; Trigonopeltastes variabilis Howden, 1968: Honduras.

Description of a new species of Lamellothyrea Krikken (Coleoptera, Scarabaeidae, Cetoniinae) from the iSimangaliso Wetland Park, KwaZulu-Natal (South Africa).

Project description:Recent data and material obtained from northern KwaZulu-Natal (South Africa) and Maputo Bay (Mozambique) have provided support for the description of a new species of the genus Lamellothyrea Krikken, 1980. The genus previously included only one species, L. descarpentriesi, with uncertain and poorly defined type locality, i.e. "Transvaal". It is now evident that two different species are actually involved, L. descarpentriesi with currently known distribution limited to the coastal area north of Maputo, and L. isimangalisosp. n. with a known distribution range virtually restricted to the iSimangaliso Wetland Park, in north-eastern KwaZulu-Natal. The two species appear to be separated by a substantial discontinuity in southern Mozambique and can be easily separated on the basis of their clypeal structure, extent of white dorsal tomentum and shape of aedeagal parameres. Both species appear to be restricted to the coastal belt, with L. isimangaliso sp. n. occupying almost exclusively dune forest habitats. In this species, adult activity depends on rainfall and shows two peaks, one at the onset of summer and the second in autumn.

Description of the female of Haematonotus jenisi Krajcik, 2006 and placement of the species within the genus Atrichiana Distant, 1911 (Coleoptera, Scarabaeidae, Cetoniinae).

Project description:The male of Haematonotus jenisi Krajcik, 2006 was described on the basis of a sole holotype specimen. A number of new specimens have recently been collected from the False Bay area of the iSimangaliso Wetland Park, in northeastern KwaZulu-Natal, including a number of females, thereby allowing the description of this sex for the first time. The new series also reveals that most morphological characters are actually typical for the genus Atrichiana Distant, 1911, rather than Haematonotus Kraatz, 1880. For this reason, it is here proposed that this species be placed within Atrichiana, thus becoming the second species of a genus that was previously regarded as monospecific, represented by the southern African endemic Atrichiana placida (Boheman, 1857). Like Atrichiana placida, Atrichiana jenisi exhibits a remarkable polymorphism, but also sexual dimorphism, particularly expressed at the level of the antennal clubs, which in the male are twice as long as in the female. Unfortunately, all specimens of the recent series were collected dead or drowning on the lake shores and therefore no further information on their life cycle and biology in general could be obtained. It seems that the species may represent a micro-endemism restricted to the Western Shores of Lake St Lucia, with habitat associated to Sand Forest and possibly also Northern Coastal Forest vegetation types.

Description and ecology of two new species of Gyronotus van Lansberge, 1874 (Coleoptera, Scarabaeidae) from southern Africa.

Project description:Recent collections in KwaZulu-Natal and Swaziland have led to the discovery of two new species of the flightless and highly threatened Scarabaeinae genus Gyronotus van Lansberge, 1874. A description of G. perissinottoi sp. n. and G. schuelei sp. n. is provided here, along with notes on their habitat and ecology. Unlike the vast majority of the species previously known in the genus, which have been reported as forest dwellers, the two new species are found during daytime in grassland/savanna vegetation, at the margin of forest patches.

Review of the genera Anelaphinis Kolbe, 1892 and Atrichelaphinis Kraatz, 1898 (Coleoptera, Scarabaeidae, Cetoniinae).

Project description:New material collected recently throughout the Afrotropical region has led to a major reassessment of taxa within the genera Anelaphinis Kolbe, 1892, Atrichelaphinis Kraatz, 1898 and other closely related genera. As a result, the name Megalleucosma Antoine, 1989 is here synonymised with Anelaphinis and a lectotype is designated for the type species, Cetoniadominula Harold, 1879. The genus Atrichelaphinis is redefined and a new subgenus, Atrichelaphinis (Eugeaphinis), is proposed for Elaphinissimillima Ancey, 1883, Elaphinisvermiculata Fairmaire, 1894, Niphetophorarhodesiana Péringuey, 1907, Atrichelaphinisdeplanata Moser, 1907 (with Anelaphiniskwangensis Burgeon, 1931 as junior synonym) and Anelaphinissternalis Moser, 1914. Additionally, three new species and one new subspecies are recognised and described in this new subgenus: Atrichelaphinis (Eugeaphinis) bomboesbergicasp. n. from South Africa; Atrichelaphinis (Eugeaphinis) bjornstadisp. n. from Tanzania; Atrichelaphinis (Eugeaphinis) garnierisp. n. from south-east Africa (Tanzania, Zimbabwe); and Atrichelaphinis (Eugeaphinis) deplanataminettiissp. n. from central Africa (Malawi, Mozambique, Congo-Kinshasa, Congo-Brazzaville, South Africa, Rwanda, Zambia, Zimbabwe). The genus Atrichelaphinis is compared to its closest relatives and two separate keys are proposed, one for Atrichelaphinis and one for the sub-Saharan genera exhibiting completely or partially fused parameres.
