Orlando, Thales Yann, Salles, Frederico Falcão, Boldrini, Rafael & Krolow, Tiago Kütter, 2021, Updated records for Leptophlebiidae (Ephemeroptera) and a new species of Thraulodes Ulmer, 1920 from Tocantins State, Northern Brazil, Zootaxa 5076 (1), pp. 39-55 : 46-47

Thraulodes sp.

Distribution. Brazil (Tocantins).

Material examined. BRAZIL, Tocantins, Arraias, rio Palmas , 12°49’50”S / 46°54’32”W, 04.vii.2018, white sheet light trap, Alvim, B.G.C. coll. (1♂, CEUFT) .

Remarks. In the same area, specimens of Thraulodes xavantinensis Mariano, Flowers & Froehlich, 2011 and one specimen of Thraulodes sp. were captured. This morphospecies resembles Thraulodes schlingeri Traver & Edmunds 1967 based on the curved telopenis. The main differences were the position of the telopenis (directed medially-ventrally on T. schlingeri versus postero-medially on Thraulodes sp. 1 ), the distribution of the spots on the abdomen (tergum II–VIII with a pair of gray midway spots on T. schlingeri versus midway spots on each tergum II–VIII absent on Thraulodes sp. 1 ) and the projection of the styliger plate (medial portion sharp on T. schlingeri versus medial portion rounded on Thraulodes sp. 1 ). The individual possibly represents a new species; however, until more specimens and different life stages can be added to the analysis, this record will be treated with a provisioal species designation. It was found in only one collecting site, an area with Cerrado influence.
