Project description:Smilidarnis is fixed as the correct original spelling. Smilidarnissimilifasciatus, sp. nov., from Bolivia and French Guiana, closely resembles S.fasciatus Andrade in being brightly colored but differs in the metathoracic tibial chaetotaxy, the male pygofer, first anal segment, aedeagus, and color pattern. In this new species, which is larger than S.fasciatus, females are larger than males. Photographs of the male and female adults and genitalia of the new species are provided. Bolivia is a new country record for the genus. A key to all species is provided.
Project description:One new leafhopper genus Paracodilia gen. n. with one new species P.geniculata sp. n., and two other new species in different genera, Bolivielaexpanda and Armaturolidiasymmetrica spp. n., are described in the tribe Coelidiini (Cicadellidae: Coelidiinae) from the Neotropical region. Photographs and illustrations are provided.
Project description:The genus Rhyncholepta Bergroth, 1911 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Chlorocorini) is redescribed and five species-group taxa are recognized, keyed, their diagnostic characters illustrated, and the distribution reviewed. Among the five taxa, two species and one subspecies are recognized as new: Rhyncholeptagrandicallosagrandicallosa Bergroth, 1911 (Brazil, Ecuador, French Guiana, Guyana, Peru, Suriname), Rhyncholeptagrandicallosacentroamericana subsp. n. (Belize, Costa Rica, Guatemala, Mexico, Panama), Rhyncholeptahenryi sp. n. (French Guiana), Rhyncholeptameinanderi Becker & Grazia-Vieira, 1971 (Bolivia, Brazil, Ecuador, Peru), and Rhyncholeptawheeleri sp. n. (Guyana). The structure of the male genital capsule was found to be the only reliable character for identifying species-group taxa. For this reason, a simultaneous application has been submitted to the International Commission on Zoological Nomenclature to set aside the non-informative female lectotype of Rhyncholeptagrandicallosagrandicallosa and replace it with the male neotype suggested herein. Based on the available label data and our field experience, most of the specimens were collected by various types of light traps in or near dense forests. Adults can be collected throughout the year.
Project description:Three new genera in Acutalini are described, two of which have two discoidal cells (R2+3 and M) in the forewing, as in Euritea Stål. Ceresinoideazackigen. nov. et sp. nov., from Guatemala, differs from other acutalines in having a pair of suprahumeral spines and a stepwise convex pronotum in lateral view. Quinquespinosaseptamaculagen. nov. et sp. nov., which is widely distributed in South America, differs in having a basal cell M and three posterior pronotal spines. Tectiformaguayasensisgen. nov. et sp. nov., from Ecuador, has the pronotum strongly tectiform throughout. A key to all genera of Acutalini is provided.
Project description:A new genus Pusulissus gen. nov. with two new species P. phiaoacensis sp. nov. and P. coronomensis sp. nov. are described respectively from Vietnam and China in the tribe Parahiraciini of the family Issidae. A molecular phylogeny using combined genes (18S, 28S, COX1 and Cytb) confirms its placement in the tribe Parahiraciini. The tribe is divided into three subtribes: Scantiniinasubtribe nov. with the type genus Scantinius Stål, 1866, and Vindilisinasubtribe nov. with type genus Vindilis Stål, 1870 plus Nisoprincessa Gnezdilov, 2017, and the nominal subtribe Parahiraciina Cheng & Yang, 1991 subtribe nov. The characteristics of these subtribes are provided, with a key to identification. Genus Folifemurum Che, Zhang & Wang, 2013 is transferred to HemisphaeriiniMongolianina, and genus Gelastyrella Yang, 1994 is maintained as a valid name.
Project description:A new species of the treehopper genus Sinocentrus Yuan, S. brevicornis Li & Chen, sp. nov. from China, is described and illustrated. A checklist and key to species of the Sinocentrus are provided.
Project description:Based on examination of holotypes or interpretation of original descriptions, four taxonomic changes are proposed for South American species erroneously placed in the tribe Smiliini: Flynnia, gen. n. (Thuridini) and F. fascipennis (Funkhouser), comb. n. from Bolivia; Antianthe atromarginata (Goding), comb. n. from Ecuador; Amastris pilosa (Funkhouser), comb. n. from Peru; and Thelia planeflava Fairmaire from Brazil to Polyglyptini incertae sedis, new placement.
Project description:Enchenopa Amyot & Serville, 1843 is a diverse treehopper genus widespread across the New World. We describe two new Enchenopa species from northwest Ecuador: Enchenopagennyae sp. nov. from urban forest remnants at the foothills of the Andes cordillera and Enchenopachocoandina sp. nov. from secondary montane forests. Enchenopagennyae sp. nov. is placed in the E.biplaga species group and is distinguished by the sexual dimorphism of the pronotal horn and lateral carina shape, the straight metopidium, 2-4 accessory carinae and the whitish dorsal spot and subapical band. Enchenopachocoandina sp. nov. belongs to the E.andina species group and is diagnosed by its reddish central carina and posterior pronotal process apex, presence of an obtuse projection rather than an anterior horn, three or four irregular accessory carinae, and apical amber forewing patch. Illustrations, notes on natural history, and keys to species of the E.biplaga and E.andina species groups are also provided.
Project description:A new genus of tribe Erythroneurini from Thailand, Thaioneura gen. n., including three new species: Thaioneura nigrilinea sp. n. (type species), Thaioneura sinuata sp. n. and Thaioneura suphanburia sp. n., is described and illustrated and a key to species is provided. The new genus exhibits a pattern of interspecific variation in the hind wing venation that has not been observed in other genera of the tribe.
Project description:In the present paper, three new species are added to the genus Tautoneura Anufriev from China, Tautoneura baiyunshanasp. n., Tautoneura caoisp. n. and Tautoneura yunnanensissp. n. A key to species recorded from China is provided.
