A new early Miocene fossil genus from Dominican amber extends the Eastern Asia distribution of Paricanini (Hemiptera: Fulgoromorpha: Tropiduchidae) to the Neotropics

Abstract

A new extinct genus and species, Seeteascanopia arcabucana gen. et sp. nov. are described from early Miocene Dominican amber. Its placement in the planthopper family Tropiduchidae, tribe Paricanini is discussed. It represents the second described New World fossil of Tropiduchidae for which a review of all fossil taxa is provided. The family is regarded as a Laurasian lineage and, in absence of a phylogenetical framework, both a Palaeocene and a more recent Oligocene dispersion scenario are discussed for the tribe to reach Hispaniola. These two possible scenarios are also suggested for another early Miocene Dominican fossil amber of Tropiduchidae of the tribe Neommatissini that exhibits a similar bipolar distribution.

A Bizarre Planthopper Nymph (Hemiptera: Fulgoroidea) from Mid-Cretaceous Kachin Amber

“…The profemur and mesofemur are subcylindrical, and protibia and mesotibia subquadrangular in S. shcherbakovi (versus protibia and mesotibia flattened and foliaceous in fossil Dorytocidae nymphs [ 14 ]; profemur and protibia, mesofemur and mesotibia dilated and foliaceous in Jubisentidae [ 45 , 46 ]). The protarsus and mesotarsus of the new species have only two segments (versus protarsus and mesotarsus usually with three segments in Dictyopharidae [ 44 ], Jubisentidae [ 45 , 46 ], Lalacidae [ 47 ], Perforissidae [ 11 , 48 , 49 , 50 , 51 ], and Tropiduchidae [ 52 , 53 , 54 ]). The metatibia is usually with lateral spines in Achilidae [ 55 ], Dictyopharidae [ 44 ], Katlasidae [ 5 ], Nogodinidae [ 56 , 57 , 58 ], Ricaniidae [ 59 ], Tropiduchidae [ 52 , 53 , 54 ], Yetkhatidae [ 60 ], and sometimes in Lalacidae [ 47 ], but our new genus does not have any lateral spines on its metatibia.…”

The hind tibial pecten is usually setigerous in Jubisentidae [ 45 , 46 ], Lalacidae [ 47 ], and Perforissidae [ 11 , 48 , 49 , 50 , 51 ], and this characteristic is also absent in S. shcherbakovi .…”

Taxonomic study of the Oriental genus Catullioides Bierman, 1910 (Hemiptera, Fulgoromorpha, Tropiduchidae), with description of a new species from China

“…The planthopper family Tropiduchidae Stål is one of twenty-one currently recognized extant families of Fulgoroidea ( Hemiptera : Fulgoromorpha ) ( Wang et al 2016 ; Bourgoin 2021 ). With more than 670 species in 196 extant and extinct genera, this family is divided into two subfamilies, Elicinae Melichar and Tropiduchinae Stål ( Bourgoin et al 2019 ; Bourgoin 2021 ). Elicinae comprises four extant tribes and two extinct tribes ( Gnezdilov 2013 ; Szwedo and Stroiński 2017 ; Bourgoin 2021 ).…”
