Derbid Planthoppers (Hemiptera: Fulgoroidea: Derbidae) Associated with Coconut and Oil Palm in Brazil

Abstract

We present surveys of derbid planthoppers associated with coconut (Cocos nucifera L.) and oil palm (Elaeis guineensis Jacq.) collected in Northeastern (Sergipe) and North (Pará and Roraima) Brazil. The surveys were intended to contribute to our knowledge of possible vectors of phytoplasmas or other phloem-restricted plant pathogens. Eight derbid taxa were found, two in the subfamily Cedusinae, tribe Cedusini (Cedusa yipara Kramer and C. yowza Kramer) and six in the subfamily Derbinae, tribe Cenchreini: Herpis sp., Persis pugnax Stål, Omolicna anastomosa (Caldwell), O. nigripennis (Caldwell), and two new species in the genus Agoo Bahder & Bartlett are described here. Genus-level features between Omolicna and Agoo are discussed and a key to the species of Agoo is provided.

A new species of planthopper in genus Herpis (Hemiptera: Derbidae) from lowland tropical rainforest in Costa Rica

“…Photographs provided by the Swedish Museum of Natural History (NHRS, Stockholm) of three species originally described by Stål, 1862 in Herpis, (H. fimbriolata, H. orba, and H. pallidovenosa) but subsequently moved to Phaciocephalus by Muir 1924: 16 were also examined (as briefly noted in Dollet et al 2020). The species described by Stål (1862) in Herpis are from Brazil, presumably the region around Rio de Janeiro, based on the title of the paper (roughly translated from Swedish as "Contribution to the Rio Janeiro area, Hemiptera fauna").…”

A new species of planthopper in the genus Agoo Bahder & Bartlett (Hemiptera: Fulgoroidea: Derbidae) from coconut palm (Cocos nucifera L.) in Jamaica

“…Additionally, the species Agoo luzdenia Bahder & Bartlett was discovered on coquito palms (Astrocaryum alatum Loomis) in Costa Rica (Bahder et al 2020b), and two more species (A. argutiola Bahder & Bartlett and A. spina Bahder & Bartlett) have been described on coconut and oil palm (Elaeis guineensis Jacq.) in Brazil (Dollet et al 2020), bringing the current number of species in the genus to six; viz. A.…”
