The genus Hintonelmis (Coleoptera: Elmidae: Elminae), new species and records

ABSTRACT

Hintonelmis is a South American genus of Elmidae, comprising 11 species. Two further new species are here described and illustrated: Hintonelmis guianensis sp. nov. from Guyana, and Hintonelmis roellae sp. nov. from Brazil, can be distinguished from all other known members of the genus by their general colour pattern, some characters of pronotal and elytral sculpture, and the morphology of the male genitalia. The type material is deposited in the Natural History Museum, London, UK and Museum of Zoology of the University of São Paulo, São Paulo, Brazil. New distributional data for species of Hintonelmis are presented for the South of Brazil, Bolivia, Ecuador, and Guyana. We also provide an updated key for the genus species.

Revision of the Chinese species of the genus Belonuchus Nordmann (Coleoptera: Staphylinidae: Philonthina)

In this paper, the Chinese species of the genus Belonuchus Nordmann, 1837 Nordmann, A. 1837. Symbolae ad monographiam staphylinorum. Ex Academiae Caesareae Scientiarum, Vol. 4, 1–167. Petropoli: Academiae Caesareae Scientiarum.  [Google Scholar] are revised. Four new species are described and illustrated: B. admirabilis sp. nov. from China (Beijing), B. applanatus sp. nov. from China (Yunnan), B. coomani sp. nov. from China (Yunnan and Guangxi) and Vietnam (Hoa-Binh) and B. obvelatus sp. nov. from Indonesia (Sumatra and Java). Belonuchus grandiceps (Kraatz, 1859 Kraatz, G. 1859. Die Staphylinen-Fauna von Ostindien, insbesondere der Insel Ceylan. Arch Naturgesch., 25: 1–196.  [Google Scholar]) and B. imitator Cameron, 1932 Cameron, M. 1932. “The Fauna of British India, including Ceylon and Burma. Coleoptera”. In Staphylinidae, Vol. III, 443London: Taylor & Francis.  [Google Scholar] are reported from China for the first time. Five existing Chinese species are re-described and illustrated: B. grandiceps, B. imitator, B. puncticulus, B. punctifrons and B. rufoniger. Belonuchus gardneri Cameron, 1932 Cameron, M. 1932. “The Fauna of British India, including Ceylon and Burma. Coleoptera”. In Staphylinidae, Vol. III, 443London: Taylor & Francis.  [Google Scholar] is placed in synonymy with B. rufoniger Fauvel, 1895 Fauvel, A. 1895. Staphylinides nouveaux de l'Inde et de la Malaisie. Rev Entomol., 14: 180–286.  [Google Scholar]. Consequently, eight species of the genus Belonuchus are now known from China. An identification key to the Chinese species of the genus Belonuchus is provided and their geographical distribution is mapped.     

A new genus and species of Neotropical Anacolini and new distributional records (Insecta,Coleoptera, Cerambycidae)

A new genus is described: Acanthocornis gen. nov., type species, Acanthocornis flavus sp. nov. from Brazil, Pará. A new species is described: Atrocolus guarani sp. nov. from Paraguay, Cordillera, which differs from Atrocolus mariahelenae Monné and Monné, 2008 Monné, MA and Monné, ML. 2008. Atrocolus mariahelenae, novo gênero e espécie de Anacolini (Coleoptera, Cerambycidae). Iheringia Sér Zool, 98(2): 215–217. [Crossref], [Web of Science ®] , [Google Scholar] principally by the sparse punctures in the occiput and pronotum and by the dull interspaces between elytral carinae. We present new distributional data for Myzomorphus gounellei Lameere, 1912 from Brazil, São Paulo, and Biribellus martinsi Galileo, 1987 Galileo, MHM. 1987. Sistemática das tribos Meroscelisini e Anacolini (Coleoptera, Cerambycidae, Prioninae) nas Américas. II, Anacolini. Rev Bras Entomol, 31(4): 481–705.  [Google Scholar] from Brazil, Rondônia, and new country data for Myzomorphus scutellatus Sallé, 1849 Sallé, A. 1849. Coléoptères nouveaux de l'Amérique. 2e partie. Ann Soc Entomol Fr, 2(7): 429–435.  [Google Scholar] and Nicias alurnoides (Thomson, 1857), both from Trinidad and Tobago, and Xanthonicias prostrata Galileo, 1987 Galileo, MHM. 1987. Sistemática das tribos Meroscelisini e Anacolini (Coleoptera, Cerambycidae, Prioninae) nas Américas. II, Anacolini. Rev Bras Entomol, 31(4): 481–705.  [Google Scholar] from Peru, Junin. All the species are illustrated.     

The bark and ambrosia beetles of the Cook Island and Niue (Coleoptera: Scolytidae and Platypodidae)

Twenty-two species of Scolytidae (including one new species), and one species of Platypodidae are recorded from the Cook Islands and Niue in the South Pacific, and a key is given to all species. Corrections are made to earlier records from the islands. Xyleborinus perexiguus (Schedl) comb. n. is transferred from Xyleborus. The faunal composition, breeding habits and geographical distribution of the species are discussed and related to those of other islands in the Pacific. Many species have probably been introduced by man. In the absence of a major timber industry, the species are likely to be of minor economic importance.     

Two new taxa from the Lesser Sundas in the genus Onthophagus (Coleoptera: Scarabaeidae: Scarabaeinae)

Two new Indonesian taxa are proposed in Onthophagus Latreille, 1802, illustrating the composite faunal spectrum of the Lesser Sundas (Indonesia): O. montishannoniae, a new species from Flores, and O. accedens nusatenggaricus, a new subspecies from Lombok and Flores. O. accedens Lansberge, 1883 is, with O. dux Sharp, 1875, placed in what is here defined as the dux subgroup within the subgenus Parascatonomus Paulian, 1932. The three included species‐group taxa are keyed, their status is discussed, and new records are given. The position of O. montishannoniae seems taxonomically and geographically isolated: this species has no known close relatives in the region, neither in the Lesser Sundas, nor anywhere else in Wallacea.     

Revision of the southern African genus Frankenbergerius Balthasar with description of new taxa (Coleoptera: Scarabaeidae: Scarabaeinae)

The southern African genus Frankenbergerius Balthasar is revised. Two new species, F. opacus sp. n. and F. nitidus sp. n. (South Africa, Western Cape), and one new subspecies, F. armatus tuberculatus ssp. n. (South Africa, Mpumalanga), are described. F. imitativus (Péringuey) is considered a junior synonym of F. forcipatus (Harold). A key to the species and notes on biology are given.     

Systematics and phylogeny of Eodrepanus,a new Drepanocerine genus,with comments on biogeographical data (Coleoptera: Scarabaeidae: Oniticellini)

We describe here Eodrepanus gen. nov., currently comprising nine species, six previously assigned to the genus Drepanocerus and three described as new (namely, E. morgani sp. nov., E. paolae sp. nov. and E. coopei sp. nov.). Two of the new species have an Afrotropical distribution, while the last is an Eemian fossil species from England. Maximum parsimony was used to analyse reciprocal relationships among the species of Eodrepanus gen. nov., and four of the 24 species remaining in Drepanocerus. Support for these phylogenies was evaluated using the Bootstrap method and Bayesian inference as implemented in MrBayes. The biogeography of Eodrepanus gen. nov. was analysed using several different methods, namely, analysis of similarity (Ochiai Index), dispersal–vicariance analysis and parsimony analysis of endemicity.

New genera and species of the Synchelidium group (Amphipoda: Oedicerotidae) from Asia-North Pacific

Four new species and two new genera belonging to the family Oedicerotidae are reported from Korea and Vietnam. Two new genera, Orthomanus and Imbachoculodes are described, with three new species, namely Orthomanus koreanus gen. et sp. nov., Imbachoculodes namhaensis gen. et sp. nov. and Imbachoculodes vietnamensis gen. et sp. nov.
