Una nueva especie del género Eugnosta Hübner, E. lankinae n.sp. (Lepidoptera: Tortricidae), es descrita para la Provincia de Elqui, Chile. Se entregan los caracteres morfológicos del adulto y las fi guras de la genitalia masculina. Además se discute su posición sistemática con dos especies congéneres Neotropicales.
A new species of Autostichidae, Eraina beechei nov. sp., is described from specimens collected in the Andean mountains of Ñuble, Biobío. Diagnostic characters for the species are presented; photographs of adults, illustrations of male and female genitalia, and a key for identifi cation of Eraina species are provided.
Ufocandona hannaleeae gen. et sp. nov. (Crustacea, Ostracoda) from an artesian well in Texas, USA
(2017)
We describe a new genus, Ufocandona gen. nov. with its type species Ufocandona hannaleeae gen. et sp. nov., from an artesian well in San Marcos, Texas, USA. The new genus has diagnostic characteristics that distinguish it from other genera in Candonidae, including the asymmetric shape of the valves, the smooth central area on the external surface of the valves, the hexagonal ornamentations around the marginal ends of the carapace, the dense spines on the marginal edges of the right valve and the dorsal prolongation and tubercles seen from inside the ventral edges of the left valve. Additional differences in the soft body parts of the male and female (e.g., claw-like uropod, shape of hemipenis, long Y aesthetascs, two short or reduced exopods on antenna, reduced numbers of setae and segments on other extremities) distinguish the new genus from others in the family. The discovery of this species from a deep artesian well contributes important information to our understanding of groundwater species diversity in a biologically diverse aquifer where the ostracod fauna has been unstudied.
Two new species of the Rhyacophila nigrocephala species group, R. voluta sp. nov. and R. linguiformis sp. nov., are described, diagnosed and illustrated. Rhyacophila voluta sp. nov. is similar to R. pentagona Malicky & Sun, 2002 in male genitalia, but can be diagnosed by the inferior appendages of the same length as the complex of preanal appendages and dorsal lobe of segment IX, fused base of the basal segments of inferior appendages, and slightly incised distal margin of apical segment of inferior appendage. Rhyacophila linguiformis sp. nov. is similar to R. rima Sun & Yang, 1995 and R. esorima Mey, 1996 in male genitalia, but can be diagnosed by the progressively narrowed complex of preanal appendages and the dorsal lobe of segment X, the short anal sclerites, and the small gap between the upper and lower lobes of apical segment of inferior appendages. An updated checklist of 23 species recorded from China is presented.
Two new species of hangingflies, Terrobittacus rostratus sp. nov. and Terrobittacus angustus sp. nov., are described and illustrated from Yunnan, southwestern China, increasing the species number of Terrobittacus Tan & Hua, 2009 to six. Terrobittacus rostratus sp. nov. differs from its congeners by wings devoid of markings and epandrial appendages slightly longer than half the length of the gonocoxites. Terrobittacus angustus sp. nov. can be recognized by wing markings along R5 distally. A key to species of the genus is updated to include the two new species.
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.
Tortonian teleost otoliths from northern Italy: taxonomic synthesis and stratigraphic significance
(2017)
The Tortonian fish otoliths of northern Italy have been studied for more than a century and represent one of the best known otolith-based teleost faunas in the Miocene of the Mediterranean Basin. Yet with the growing knowledge on Recent otoliths, an updated taxonomic overview of this fauna is needed. Moreover, new material from hemipelagic Tortonian marls sampled at nine localities is described herein, revealing 109 taxa of which 88 are recognised at species level. Four of these are new: Coryphaenoides biobtusus sp. nov., “Merluccius” rattazzii sp. nov., Neobythites auriculatus sp. nov. and Lesueurigobius stironensis sp. nov. The compilation of previously studied and newly acquired material revealed a total of 118 nominal Tortonian species. At generic level, the fauna is characterised by many modern forms; more than 90% can be assigned to present day genera. At species level, however, more than half of the represented taxa are extinct. Based on the fossil otolith record, the Tortonian fauna of the Mediterranean is most similar to that of the Langhian (Badenian) of the Central Paratethys by sharing many extinct Miocene species, but it is also very close to that of the Pliocene Mediterranean, by sharing many modern Atlantic-Mediterranean forms. The Tortonian fauna is further characterised by many species that are apparently confined to the upper Miocene, resulting in a unique combination of its taxonomic composition.
