Abstract
Portanini Linnavuori, 1959 is a small tribe of neotropical leafhoppers that includes two genera: Portanus Ball, 1932 and Metacephalus DeLong & Martinson, 1973. Herein, a checklist of portanines from Peru is given, including several new species records for the country, elevating the known diversity from nine to 22 species. In addition, four species have their department ranges expanded in Peru. Two new portanine species are also described: Metacephalus mamaquilla sp. nov. and Portanus tambopata sp. nov. both from Tambopata National Reserve, Madre de Dios, Peru and we make available habitus photos of other Portanini species from this reserve.
Highlights
The hemipteran infraorder Cicadomorpha comprises approximately 35,000 described species of plant sap-sucking insects distributed worldwide (Dietrich, 2005)
Included in the subfamily Aphrodinae by Dietrich (2005), Portanini was erected by Linnavuori (1959) as one of the leafhopper tribes restricted to the Neotropical region
The present revision of leafhopper material collected in Tambopata National Reserve, as well as, Peruvian material from different collections, resulted in the finding of two undescribed species and a great number of new species records from Peru
Summary
The hemipteran infraorder Cicadomorpha comprises approximately 35,000 described species of plant sap-sucking insects distributed worldwide (Dietrich, 2005). With approximately 21,000 species, 2,550 genera and 25 subfamilies, Cicadellidae is the largest hemipteran family, being cosmopolitan in distribution, occurring everywhere plants (their hosts) can survive (Dietrich, 2013; Bartlett et al, 2018). Included in the subfamily Aphrodinae by Dietrich (2005), Portanini was erected by Linnavuori (1959) as one of the leafhopper tribes restricted to the Neotropical region. The tribe include 63 valid species divided into two genera: Portanus Ball, 1932 and Metacephalus DeLong & Martinson, 1973 with 49 and 14 valid species, respectively (Felix & Mejdalani, 2016; Souza, Takiya & Felix, 2017; Carvalho & Cavichioli, 2017; Freytag, 2017; Felix et al, 2020).
