Abstract

Costanana DeLong & Freytag, 1972 is a Neotropical genus of leafhoppers currently comprising 13 species with a wide distribution from Mexico to Argentina. In this study, eight new species of Costanana are described, C. xenomorpha sp. nov. from Department of Cuzco, Peru, and seven Brazilian species: C. alata sp. nov. from Minas Gerais State; C. bifida sp. nov. from Paraná and Mato Grosso states; C. cifi sp. nov., C. obtusa sp. nov. and C. piraquarensis from Paraná State; C. luzi sp. nov. from Distrito Federal; and C. rubromarginata sp. nov. from Mato Grosso and Pará states. We propose that Costanana cella DeLong & Freytag, 1972 is a junior synonym of C. praecellens (Stål, 1862) and C. asymmetrica DeLong & Freytag, 1972 is a junior synonym of Gypona viridans DeLong & Martinson, 1972. Costanana costata DeLong &Freytag, 1972 and C. flavicosta (Stål, 1862) are transferred to Gypona Germar, 1821, C. minuta (Spångberg, 1878) is transferred to Acuponana DeLong & Freytag, 1970 and Gypona nupera Van Duzee, 1907 is transferred to Costanana. Gypona costata comb. nov. and Costanana santana DeLong & Wolda, 1983 are newly recorded from Pernambuco State, and Gypona flavicosta comb. nov. is recorded from Espírito Santo and Paraná states, Brazil. The female genitalia of Costanana flavina DeLong & Freytag, 1972, C. praecellens and Gypona flavicosta comb. nov. are described and illustrated for the first time and a brief note on feeding behavior is given for C. flavina and C. praecellens. A key to males and a new diagnosis are provided for Costanana. We also describe and illustrate Metacostana cornuta gen. et sp. nov., a new Brazilian genus for Gyponini sharing characteristics with Costanana, Acuthana Domahovski & Cavichioli, 2018, Domahovana Silva et al., 2022 and Dumorpha DeLong & Freytag, 1975.

Costanana DeLong&Freytag八新种（半翅目：蝉科：Gyponini）：分类变化、雄性关键和Metacostana gen.nov.的描述。

Costanana DeLong和Freytag，1972是一个新热带叶蝉属，目前包括13种，广泛分布于墨西哥和阿根廷。在本研究中，描述了八个Costanana新种，来自秘鲁库斯科省的C.xenomorpha sp.nov.和七个巴西物种：来自米纳斯吉拉斯州的C.alata sp.nov；来自巴拉那州和马托格罗索州的C.bifida sp.nov；来自巴拉那州的C.cifi sp.nov.、C.obtsa sp.nov..和C.piracquarensis；来自Distrito Federal的C.luzi sp.nov；和马托格罗索州和帕拉州的C.rubromarginata sp.nov。我们提出Costanana cella DeLong&Freytag，1972是C.praecellens（Stål，1862）的初级同义词，C.asymmetrica DeLong和Freytag（1972）是Gypona viridans DeLong and Martinson，1972的次级同义词。Costanana costata DeLong和Freytag，1972年和C.flavicosta（Stål，1862年）被转移到Gypona Germar，1821年，C.minuta（Spångberg，1878年）被转让到Acupona DeLong&Freytag（1970年），Gypona nupera Van Duzee，1907年被转移到Costanana。Gypona costata梳。11月。和Costanana santana DeLong和Wolda，1983年是伯南布哥州和Gypona flavicosta梳的新记录。11月。记录于巴西圣埃斯皮里托州和巴拉那州。黄腹蟾蜍的雌性生殖器DeLong和Freytag，1972，C.praecellens和Gypona flavicosta comb。11月。首次对其进行了描述和说明，并简要介绍了C.flavina和C.praecellens的饲养行为。为Costanana提供了一个雄性的钥匙和一个新的诊断。我们还描述和说明了巴西一个新的Gyponini属Metacostana cornuta gen.et sp.nov.与Costanana、Acutana Domahovski和Cavicioli，2018、Domahovana Silva等人，2022和Dumorpha DeLong和Freytag，1975具有共同特征。

期刊介绍： EJT is a fully refereed, international, fully electronic Open Access journal in descriptive taxonomy, covering subjects in zoology, entomology, botany (in its broadest sense), and palaeontology. EJT-papers must be original and adhere to high scientific (content) and technical (language, artwork, etc.) standards. Manuscripts that are clearly substandard in either of these categories will not be sent out for review. EJT is supported by a consortium of European Natural History Institutes, but its scope is global. Both authorship and geographical region of study need not be European. Authors are, however, strongly encouraged to involve European Natural History collections by consulting material or by depositing specimens (e.g. types and figured material) related to their published paper in the collection of a European Natural History Institute.
