Hagenulopsis sp.

Distribution. Brazil (Tocantins).

Material examined. BRAZIL, Tocantins, Palmas, distrito of Taquaruçu do Porto, vale do Vai Quem Quer , 10°22’0.9”S / 48°8’1”W, 27-30.viii.2019, white sheet light trap, Fernandes, A.S. and team cols. (3♂, CEUFT) .

Remarks. This species appears to be very close to Hagenulopsis minuta Spieth 1943 . The main differences are in the length of the body between the specimens sampled in the state of Tocantins and Surinam (4.7 – 5.1 mm versus 3.0 mm, respectively). Additionally, we found differences in the length of the penes and in the development of the eye bridge on the inner margin of the upper portion, which is present but poorly developed. Since there are no described specimens until now with a poorly developed bridge and based on those differences, this record will be treated as an undescribed species until more specimens can be added to the analysis. It was found in only one site, in an area with Cerrado influence.
