Paraedessa, a new genus of Edessinae (Hemiptera: Heteroptera: Pentatomidae)

摘要

The new genus Paraedessa is proposed, to include four species previously placed in Edessa. The new genus is characterized by males with the pygophore showing a lateral expansion of proctiger, and females with gonocoxites 8 reduced; go-napophyses 8 exposed and sclerotized. The species are very similar and their identification is possible only by comparing genitalia. New combinations proposed are Paraedessa stolida (Linnaeus) from Suriname and Brazil; P. heymonsi (Bred-din) from Peru and Bolivia; P. verhoeffi (Breddin) from Venezuela, Colombia, Peru and Brazil and P. paravinu/a (Barber) from Puerto Rico. New species proposed are P. albomaculata from Suriname; P. cyanodorsata from Costa Rica, Panama and Venezuela; P. ecuadoriensis from Colombia and Ecuador; P. si/vicola from French Guiana; P. subretangulata from Nicaragua, Costa Rica, Colombia and Venezuela. The species were illustrated and photographed. Descriptions were made using mostly male and female genitalia external morphological characters. Akey and distribution map for the species are also provided.
