The Afrotropical planthopper genus Centromeriana Melichar, 1912 (Hemiptera, Fulgoromorpha, Dictyopharidae, Dictyopharinae, Orthopagini) is revised. Four species are included: C. jocosa (Gerstaecker, 1895) (the type species, with confirmed records from Cameroon, Equatorial Guinea and Gabon), C. lindbergae sp. nov. (described from Sierra Leone), C. rhinoceros sp. nov. (described from Togo) and C. simplex Melichar, 1912 (so far only known from Equatorial Guinea, Bioko island). Lectotypes are designated for C. jocosa and C. simplex and both species are redescribed including habitus photographs and detailed illustrations of the male and female genitalia which are published for the first time. A key for identification of the species of Centromeriana is provided. As far as known, the genus is endemic to the (Guineo-)Congolian region of western Africa.
A new genus is erected within the Cetoniini to describe a newly discovered species with characters shared between Heteroclita Burmeister, 1842, Ichnestoma Gory & Percheron, 1833 and Meridioclita Krikken, 1982. Neoclita pringlei gen. et sp. nov. exhibits a simple clypeal structure without specialized armour, along with hypertrophic and hairy tarsal segments as well as a fully winged female. The new species also exhibits an aedeagal structure closest to Meridioclita, with dorsal lobes of parameres substantially narrower than the ventral ones. The species appears to be restricted to high altitudes in the southwestern peri-Drakensberg area of the Eastern Cape Province, South Africa. Similarly to other mountain relicts known from the southern African region, adults emerge only after major rainfall events during the late spring to early summer season and do not show any evidence of feeding. It appears that flying activity may be temporarily interrupted following soil desiccation, to resume promptly after the next rainfall.
In this work we present a revision of the genus Ommatoiulus Latzel, 1884 in Portugal. Based on recently collected material and older museum samples, including type specimens, we describe six new species to science, viz. Ommatoiulus alacygni sp. nov., O. camurus sp. nov., O. denticulatus sp. nov., O. litoralis sp. nov., O. staglae sp. nov. and O. stellaris sp. nov. The species O. alacygni sp. nov., O. denticulatus sp. nov. and O. staglae sp. nov. described from the Algarve are outstanding by their extremely reduced mesomerital process. The species O. porathi (Verhoeff, 1893) and O. andalusius (Attems, 1927) are recorded and redescribed for the first time after their original description. The finding of O. andalusius – originally described from Andalusia in Spain – constitutes a new record for Portugal together with two species, viz. O. fuentei (Brolemann, 1920) and O. martensi Mauriès, 1969. The taxonomic status of several species is revised. Thus Archiulus (Schistocoxitus) cingulatus Attems, 1927 is here considered as a junior synonym of Ommatoiulus lusitanus (Verhoeff, 1895) while Schizophyllum cervinum Verhoeff, 1910 is synonymized with Ommatoiulus moreleti (Lucas, 1860). An identification key to all hitherto known Portuguese species of Ommatoiulus is presented as well as a distribution map illustrating the various species occurrences in the country.
Two new genera and species of tiger beetles from Baltic amber (Coleoptera: Carabidae: Cicindelinae)
(2017)
Two fossil tiger beetle species (Coleoptera, Carabidae, Cicindelinae) are described from Eocene Baltic amber using light microscopic and X-ray microscopic techniques. Both species are considered representatives of the subtribe Iresina Rivalier, 1971 due to the shared combination of character states: glabrous head, six labral and four suborbital setae, and glabrous pronotum. Palaeopronyssiformia groehni Wiesner, Will, and Schmidt, new genus, new species, is characterized by a glabrous and furrowed head with six labral setae, large eyes, presence of two supraorbital setae on each side, mandibles with two teeth of the incisor region, and a glabrous and furrowed pronotum. Palaeoiresina cassolai Wiesner, Will, and Schmidt, new genus, new species, is characterized by a unicolored, undentated labrum, mandibles with two teeth of the incisor region, glabrous head with six labral setae, two clypeal setae, two supraorbital setae on each side, and a glabrous pronotum, mesepisternum, mesepimeron, and metepisternum. The species described here represent the only known tiger beetle fossils preserved in Baltic amber.
The genus Synaldis Foerster, 1863 is recorded in the Neotropical region for the first time. Five new Neotropical species, S. brasiliense Peris-Felipo, sp. nov., S. fritzi Peris-Felipo, sp. nov., S. longiflagellaris Peris-Felipo, sp. nov., S. magnioculis Peris-Felipo, sp. nov., and S. novateutoniae Peris-Felipo, sp. nov., are described and illustrated. The original combination for Synaldis ulmicola Ashmead, 188
Big and beautiful: the Megaxyela species (Hymenoptera, Xyelidae) of East Asia and North America
(2017)
Megaxyela Ashmead, 1898 comprises 13 species, four of which are described as new and one is removed from synonymy: Megaxyela euchroma Blank, Shinohara & Wei sp. nov. from China (Zheijang), M. fulvago Blank, Shinohara & Wei sp. nov. from China (Hunan, Jiangsu, Zhejiang), M. inversa Blank & D.R. Smith sp. nov. from the USA (West Virginia), M. langstoni Ross, 1936 sp. rev. from the eastern USA, and M. pulchra Blank, Shinohara & Sundukov sp. nov. from China (Hubei, Jilin, Liaoning, Shaanxi, Tibet), South Korea (Kangwon-do) and Russia (Primorskiy Kray). The male of M. parki Shinohara, 1992 is described for the first time. A lectotype is designated for M. gigantea Mocsáry, 1909. A cladogram, based on COI sequences of seven species, is presented and interpreted in view of selected morphological characters. Records of M. fulvago sp. nov. from Hunan and of M. pulchra sp. nov. from Tibet extend the known distribution of Megaxyela in the Old World 600 kilometers farther south and 2500 kilometers farther west than previous records.
A new species of the genus Teinobasis Kirby is described from the Muller Range in Western Province, Papua New Guinea. Its male is distinguished from all other Teinobasis species by having a pale labrum, an extensively bright orange thorax, and ventrally bowed superior anal appendages that are markedly shorter than the plump, apically rounded inferiors. Characters of the male are illustrated, and the affinities of the new species are discussed.
Species descriptions, keys to genera and species, and geographical distributions are presented for 43 species of the family Bruchidae (Coleoptera: Chrysomeloidea) for Chile. Of these species, seven are described as new:
Acanthoscelides aricae sp. nov., Lithraeus chillan sp. nov., L. comptus sp. nov., L. elguetai sp. nov., L. limari sp. nov., L. lonquimay sp. nov., and L. penai sp. nov. Eight species are endemic to Chile. A list of true host plants and floral records for those with known host associations is presented. Habitus photographs and drawings of pertinent body parts, including male genitalia, are provided. References pertaining to the previously described species are listed.
From a moss sample collected in the Manabí Province in Ecuador, we extracted 96 specimens of a new species of eutardigrade. No eggs were found. In order to obtain eggs, an in vitro culture was prepared. In total, 136 specimens (including ten simplex), one exuvia and 44 eggs (including two with embryos) of the new species were obtained. In addition to the traditional taxonomic description with morphometrics, light and scanning microscopy imaging, we also provide nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) DNA fragments of the new species. Macrobiotus polypiformis sp. nov. belongs to the hufelandi group and is most similar to Ma. paulinae Stec, Smolak, Kaczmarek & Michalczyk, 2015, but differs from it mainly by the lack of dorso-lateral patches of granulation on the cuticle, egg processes with longer and more numerous filaments and in some morphometric characters of both eggs and adults. Moreover, we provide a short discussion on the modifications/abnormalities of the claws in eutardigrades and the possible consequences on the taxonomic status of Mesobiotus armatus (Pilato & Binda, 1996), suggesting its consideration as species inquirenda (with uncertain taxonomic status).
