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.     

Revision of the obligate mushroom‐feeding African “dung beetle” genus Coptorhina Hope (Coleoptera: Scarabaeidae: Scarabaeinae)

The African genus Coptorhina Hope is revised. Nine new synonymies are established which reduces the number of valid names from 15 to six. One new species is also described. The name changes are the following: C. subaenea Janssens, C. bicolor Ancey, C. pygmaea Balthasar and C. saganicola Müller are considered junior synonyms of C. nitidipennis Boheman; C. africana Hope, C. vicina Péringuey, C. obtusicornis Boheman, C. punctata Ferreira and C. optata Péringuey are considered junior synonyms of C. klugii Hope. The new species, C. excavata sp. n., is described from southern Africa. A key to the species and notes on biology are given.     

Borneodessus zetteli,new genus and new species,notes on biogeography and a checklist of Dytiscidae from Borneo (Insecta: Coleoptera: Dytiscidae)

A new genus of Dytiscidae, Borneodessus gen. n., is described for Borneodessus zetteli zetteli sp. n. (Sabah, East Malaysia) and Borneodessus zetteli kalimantanensis ssp. n. (East Kalimantan, Indonesia). The new genus belongs to the tribe Bidessini because of the presence of two-segmented parameres of the aedeagus. A modified male clypeus is an apomorphy for Borneodessus zetteli. The species habitually resembles some species of Africodytes Biström, 1988 (Africa), Amarodytes Régimbart, 1900 (South America), and some Clypeodytes Régimbart, 1894 (Old World tropics). However, a sister group relation or closer affinities to any of the genera of Bidessini could not be established. Borneodessus is so far the first genus of Dytiscidae which is endemic to Borneo, but we suggest a certain probability of its occurrence in other Sundaic areas. The species is a rheobiont, being collected from forest streams. We briefly address biogeographical aspects and provide a checklist of Bornean Dytiscidae, indicating the currently known degree of endemism.     

The first record of a benthic polar chaetognath: a new Spadella from the Antarctic

A new benthic chaetognath, Spadella antarctica n. sp., is described from depths between 193 and 500 m in the Weddell Sea (Antarctic Ocean) and comparisons are made with related species of Spadella. Ecological remarks on this genus are provided.     

A new species of the subterranean genus Oodinotrechus Uéno, 1998, from northern Guangxi,China, with additions to the generic diagnosis (Coleoptera: Carabidae: Trechinae)

A new eyeless species, Oodinotrechus liyoubangi n. sp, is described from northern Guangxi. All specimens of this interesting species were collected in three limestone caves in Mulun National Nature Reserve of northern Guangxi, southern China. It is the second species for the genus Oodinotrechus Uéno, 1998, distinguished from the type species O. kishimotoi Uéno, 1998 by its visible scutellum and pronotal structure. Several additional diagnostic characters for the genus and a geographical distribution map for both known species are also provided.

A review of the encyrtid wasp tribe Aenasiini,with descriptions of new Afrotropical taxa (Hymenoptera: Chalcidoidea)

The tetracnemine tribe Aenasiini is discussed and a key is provided for the separation of the nine genera that can be attributed to this tribe. Neodiscodes is synonymized with Aenasius and the following seven species, which were originally assigned to the former genus, are transferred to Aenasius as new combinations: abengouroui (Risbec), comperei (Kerrich), lepelleyi (Kerrich), martinii (Compere), indicus (Narayanan & Subba Rao), parvus (Kerrich) and subbaraoi (Kerrich). A key is given for the separation of the four Afrotropical species of Aenasius and the male of A. comperei is described for the first time. Incisencyrtus gen. n. is described for the following three new Afrotropical species: secus (the type-species), sirus and afer. Cladiscodes incisius sp. n. is described from South Africa and it represents the first species of this genus from Africa. New distribution records are given for three Alfrotropical species of Metaphaenodiscus.     

Mites of the genus Malaconothrus (Acari: Cryptostigmata) from the British Isles

Two new species of Malaconothrus (M. purvisi and M. scutatus) are described. The status of this genus in the British Isles is clarified and a key is provided to the species.     

A new diagnosis for Dinaphorura (Collembola: Onychiuridae: Tullbergiinae) and description of new species from Australia

Dinaphorura tooheyensis n. sp., the fourth species of Dinaphorura recorded from Australia, is described from Toohey Forest, a eucalypt woodland, in southeast Queensland. The new species differs from existing species in the genus in that it possesses only a single spiniform process on abdomen VI instead of the usual five or seven and the generic diagnosis has been modified accordingly. Ecological notes on D. tooheyensis are provided as well as a check list and key to species in Dinaphorura.     

Jumping plant‐lice of the family Phacopteronidae (Hemiptera: Psylloidea) from Cameroon

Nine species of the family Phacopteronidae are recorded from Cameroon. All are assigned to the large pan‐tropical genus Pseudophacopteron. Eight species are described as new, and P. electum Capener is redescribed. The species are diagnosed and illustrated, and keys for the identification of adults and fifth instar larvae are provided. Information is given on distribution, host plants, and biology. Eight species are associated with plants of the order Rutales/Sapindales (three Sapindaceae, one Burseraceae, one Burseraceae or Anacardiaceae, one Meliaceae, one Rutaceae, and one Anacardiaceae/Simaroubaceae); host plants of one species remain unknown. Four species, namely P. electum, P. fuscivenosum sp. n., P. lecaniodisci sp. n., and P. morion sp. n., induce nut or pit galls on the leaves.     

The genus Thoradonta in Thailand (Orthoptera: Tetrigidae: Scelimeninae) with description of two new species

The genus Thoradonta Hancock (Orthoptera: Tetrigidae: Scelimeninae) is newly reported from Thailand. Two new species of the genus, Thoradonta lativertexoides sp. nov. and Thoradonta spiculobaoides sp. nov., are described and illustrated with photographs and compared with similar species. A taxonomic review of the genus Thoradonta is provided and a key to all known species of the genus is given.     

Notes on the Amazonian genus Hyogonia China (Hemiptera: Cicadellidae: Proconiini) with a description of a new species

Oncometopia batesi Distant, described from northern Brazil (State unknown), is transferred to the genus Hyogonia China. Hyogonia brasiliana sp. nov. is described from Northern Brazil, Pará State, the easternmost record of the genus. The new species is easily distinguished from all other Hyogonia species by the following combination of characters: (1) pronotum without distinct transverse contrasting band; (2) pygofer with short processes that do not attain its apex; (3) both pairs of aedeagal atrial processes divergent and short, never longer than aedeagal shaft; and (4) aedeagal caudal pair of atrial processes with bases close to each other, appearing as a single bifurcated robust process. Hyogonia batesi and H. brasiliana, together with an unidentified female from Acre State, represent the first authentic records of the genus Hyogonia from Brazil. Previous records of H. reticulata (Melichar) and H. youngi Emmrich and Lauterer from Brazil are erroneous as their recorded locality ‘Cumbase’ is most probably located in Peru (San Martín Department). Other new records from countries and major federal divisions are noted as follows: the genus Hyogonia (unidentified species) from Barinas State (Venezuela); H. batesi from Ecuador (Orellana Province); H. reticulata from Amazonas and Junín Departments (Peru); and H. youngi from Ecuador (Napo Province). A key to the known species of Hyogonia is provided.     

A revision of Tachyphron Brown and description of two new genera within the Ariphron group (Hymenoptera: Tiphiidae)

The Australasian genus Tachyphron Brown is revised, and two new New Guinean genera, Deuterothynnus gen. n. and Heligmothynnus gen. n., described. Fifteen species are included in Tachyphron of which seven are described as new (T. aculeatus sp. n., T. athertonensis sp. n., T. mantonensis sp. n., T. neosubfragilis sp. n., T. nigrisetatus sp. n., T. planus sp. n. and T. townsvillensis sp. n.), and a further two, Aelurus comatus Smith and Aelurus fragilis Smith, transferred from Tachynomyia. Thynnus insularis Smith is transferred from Tachynomyia Guérin to Deuterothynnus and a further three new species, D. fulvicentratus sp. n., D. fulvisetatus sp. n. and D. parallelus sp. n. described. Aelurus atratus Cameron and Takyomyia sabronensis Kimsey are transferred from Tachynomyia and Tachyphron, respectively, to Heligmothynnus and a further two new species, H. microspinus sp. n. and H. neoaratus sp. n. described. T. megacephala (Turner) is synonymized with Tachynoides flavopicta (Ritsema) and, therefore, removed from Tachyphron. A key to the Ariphron group of genera is provided, as well as keys to the males of Tachyphron, Deuterothynnus and Heligmothynnus, although the male of D. insularis is associated tentatively with the female holotype only on the basis of collection records. Only the females of D. insularis, T. armidalensis Brown and T. subtriangularus Brown are known, the latter two being described for the first time. Evidence is presented to suggest that T. subtriangularus may be bivoltine in northern Australia.
