Abstract
Two new species of Regalana DeLong Freytag, 1975 are described and illustrated: Regalana jamari sp. nov. and Regalana madeira sp. nov., both from State of Rondônia, Northern Brazil. Delongiana gen. nov. is described within Gyponini, based on two new species from Brazil: Delongiana ramosa sp. nov., designated as type-species, from Minas Gerais and Paraná states and Delongiana baiana sp. nov. from Bahia and Rio de Janeiro states. The new genus can be distinguished from other Gyponini genera based on the combination of the following features: crown slightly produced, parallel striated; crown-face transition distinct, thick and striated; male pygofer with an oblique integument thickening near dorsal margin; subgenital plate very narrow and elongated; connective Y-shaped; style elongated with apex foot-shaped; aedeagus with dorsal apodemes strongly developed, shaft cylindrical and curved dorsally, with processes near mid-length and without apical processes. Additionally, new country records are given for Regalana bobbyi and R. dianae and state records to R. sheilae.
