Abstract
The Oriental genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Purusha Distant, 1906 is reviewed and a key to the genera of Eurybrachini is given. Two new species, P. bellissima sp. nov. and P. vietnamica sp. nov. are described from Myanmar and North Vietnam, respectively. Purusha rubromaculata Distant, 1906 is proposed as a junior synonym of P. reversa (Hope, 1843). All species are illustrated, including all type specimens and the male genitalia for the first time. Distribution maps, identification key to species and biological data are provided. The sexual dimorphism in the genus is discussed. Five species are currently placed in Purusha.
Highlights
The family Eurybrachidae Stål, 1862 is a small family of planthoppers (Fulgoromorpha Evans, 1946) with 41 genera and 201 species, representing only 1.7% of the genera and 1.5% of the species of Fulgoromorpha
Eurybrachidae represent a characteristic component of the planthopper fauna of the Oriental Region where it counts 12 genera and 82 species distributed in two subfamilies
All Oriental genera of Eurybrachidae are restricted to the Oriental Region and very little information on the biology and host plants is generally available
Summary
The family Eurybrachidae Stål, 1862 is a small family of planthoppers (Fulgoromorpha Evans, 1946) with 41 genera and 201 species, representing only 1.7% of the genera and 1.5% of the species of Fulgoromorpha. Eurybrachidae represent a characteristic component of the planthopper fauna of the Oriental Region where it counts 12 genera and 82 species distributed in two subfamilies. The second subfamily Eurybrachinae Stål, 1862 is present in the Oriental and Afrotropical regions and divided in three tribes; two of them, Eurybrachini Stål, 1862 (5 genera) and Frutini Schmidt, 1908 (1 genus) are restricted to the Oriental Region while the third one, Loxocephalini Schmidt, 1908, is represented in both the Afrotropical (3 genera) and Oriental (5 genera) regions, where the distribution of a few species slightly extends to the southeasternmost part of European Journal of Taxonomy 602: 1–40 (2020). All Oriental genera of Eurybrachidae are restricted to the Oriental Region and very little information on the biology and host plants is generally available. Some key male specimens have recently become available, which allows to complete a comprehensive revision of the genus Purusha as the fifteenth part of the ongoing revision of the family
