Abstract
A new species of the cosmopolitan genus Discothyrea Roger, a member of the Proceratiinae subfamily, is described for the Brazilian Atlantic Forest. The species, Discothyrea bobi sp. nov., is compared to the other New World species described for the genus so far. Two putatively important morphological features of the genus, the palpal formula and the antennal pits, are discussed.
Highlights
Discothyrea is a charismatic genus of ants composed of tiny species living in the litter, rotten logs and soil
There are currently 48 extant and 2 fossil species (Hita-Garcia et al, 2019a) and they are present in all biogeographic regions, their diversity in the Nearctic and Palearctic regions is very low (Guénard et al, 2017; Janicki et al, 2016)
Collection data of the specimens which were physically examined were uploaded to Antweb and are the following: D. clavicornis: UFV-LABECOL-011157, UFV-LABECOL-011171, UFV-LABECOL-011186, UFVLABECOL-011183, UFV-LABECOL-011021; D. horni: UFVLABECOL-011185, UFV-LABECOL-009622; D. neotropica: UFV-LABECOL-000067, UFV-LABECOL-000068, UFV-LABECOL-008587; D. sexarticulata: UFVLABECOL-000011, UFV-LABECOL-000008, UFV
