A generic reclassification of the Afrotropical Bolboceratini (Coleoptera: Geotrupidae) Naturalis
Krikken, J..
The generic classification of the Afrotropical Bolboceratini is discussed. Fourteen genera are recognized, five of them new: Bolboceratellus, Bolbodius, Bolboceratex, Namibiobolbus and Meridiobolbus. Microbolbus Vulcano et al. is synonymized with Mimobolbus Vulcano et al. Bolbaffroides and Bolboceratops are raised to generic rank. The genera are keyed, diagnosed, and their species are listed. Many new combinations are proposed, mainly for species hitherto combined with Bolboceras Kirby.

A neglected trichiine beetle from Costa Rica (Coleoptera: Cetoniidae) Naturalis
Krikken, J..
Giesbertiolus linnaei spec. nov. is described after a female from Costa Rica, in order to prevent this unusual beetle, collected as long ago as 1895, from falling into oblivion. It is compared with the two known Giesbertiolus species and with other Mesoamerican Trichiini. The ignorance as to the precise relationships of the three species included is briefly discussed.

A new key to the suprageneric taxa in the Beetle Family Cetoniidae, with annotated lists of the known Genera Naturalis
Krikken, J..
A revised key to the subfamilies, tribes and subtribes of the Cetoniidae (Coleoptera: Scarabaeoidea) is presented. Comments are given on the classification implied by the key, which includes several redefinitions. All the known genera (ca. 510) are listed under their tribe or subtribe, the position of several being different from that in Schenkling's catalogues (1921, 1922). References to recent synoptic literature are given. Eighteen new subtribes are proposed, the majority in the tribe Cremastocheilini. One new tribe is proposed, the Platygeniini. Attention is drawn to various new and neglected synonymies, original spellings, and other nomenclatural matters regarding family-group and genus-group names. The position of many genera is briefly discussed....

Het Nederlandse dierenrijk Naturalis
Koomen, P.; Nieukerken, E.J. van; Krikken, J..
Alle in Nederland vastgestelde diergroepen worden hieronder kort besproken met de volgende standaardindeling: WETENSCHAPPELIJKE NAAM - NEDERLANDSE NAAM Korte karakterisering van de diergroep. NL - Het aantal in Nederland vastgestelde soorten, de hoeveelheid daarvan die niet echt inheems is, en eventueel het aantal alleen uit ons land bekende soorten en het aantal (nog) te verwachten soorten (d.w.z.: waarschijnlijk in Nederland aanwezig, maar nog niet ontdekt), met bronnen. Eventueel zijn de bij ons soortenrijkste deelgroepen (meestal families) vermeld of is een overzicht van de groep in tabelvorm toegevoegd. VERANDERINGEN - Informatie over toe- of afname van het aantal soorten en de (mogelijke) oorzaken daarvan. Melding van in Nederland uitgestorven...

Interessante Aphodius-soorten (Coleoptera: Scarabaeoidea) uit mest van Nederlands grofwild Naturalis
Krikken, J..
The scarab fauna of dung from Dutch red deer and wild boar is recorded and discussed. Dung samples collected during four visits to the forested region South of Apeldoorn were extracted and numbers per species were counted (table 1). The samples contained one species new to the Netherlands (Aphodius zenkeri Germar), three species considered rare (A. maculatus Sturm, A. fasciatus Olivier, A. lividus Olivier), as well as 21 more common scarab species. Further Dutch records of these species and of A. corvinus Erichson are added. The distribution of these species and of some absent from the list is briefly discussed. A. zenkeri, maculatus, and fasciatus are thought to frequent shaded habitats because of a restricted drought tolerance.

Large-eyed Onthophagus species of Sundaland: a key and descriptions of five new species (Coleoptera: Scarabaeidae) Naturalis
Krikken, J.; Huijbregts, J..
Seven species of the scarab genus Onthophagus Latreille are keyed and described. They are all characterized by the possession of large eyes (in full-face view), a feature possibly related to nocturnal habits. Traditionally these species are placed in Micronthophagus Balthasar, which is here argued to be a polyphyletic group. Five species are new: paroculus (Sumatra), setoculus (Sumatra), sideki (Sumatra, Borneo), phillippsorum (Borneo), collinsi (Borneo). Of two old species, O. drescheri Paulian and rotundicollis Lansberge, new records are given.

Notes on African Onitini, mainly from Southeastern Kenya (Coleoptera: Scarabaeidae) Naturalis
Krikken, J..
Onitini collected in East Africa (mainly southeastern Kenya) are discussed. The distribution of onitine species over Kenya, Tanzania, Uganda, and Tsavo National Park is reviewed (table 1). Three new species and one new subspecies are described and illustrated, viz., Onitis bispicticollis, kingstoni, pseudojansenii, sulcipennis subsp. naromorus (all from Kenya). For species described from other parts of Africa lectotypes are designated, viz., Onitis obscurus Lansberge, vanderkelleni Lansberge, vethi Lansberge (junior synonym of fabricii Roth), westermanni Lansberge. Onitis decellei Frey is a junior synonym of 0. violaceus Lansberge and a junior homonym of 0. decellei Paulian (junior synonym of viridulus Reiche). Further notes concern identification,...

Notes on asian Cremastochiliform genera, with descriptions of two new species (Coleoptera: Cetoniidae) Naturalis
Krikken, J..
A key to the Asian cremastochiliform genera is given. Three synonymies are emphasized: Clinterocera Motschulsky (= Callynomes Westwood); Campsiura Hope (= Macroma Gory & Percheron); Spilophorus Schaum (= Pseudospilophorus Kraatz). A new synonymy is: Periphanesthes Kraatz (= Bonsiella Ruter). The authorship of one species is established: Praona niveosparsa (Mohnike). The publication dates of Westwood's Thesaurus Entomologicus Oxoniensis are discussed. The type-material of the Leiden museum is listed; six lectotypes are designated. Two new species are described and illustrated: Campsiura celebensis (Sulawesi) and Parapilinurgus hiekei (Assam).
