Anacroneuria jaciara Bispo & Neves, 2005

Fig. 3A–F

Anacroneuria jaciara Bispo & Neves , in Bispo, Neves & Froehlich, 2005: 2 ; Froehlich, 2010: 159; Ribeiro & Gorayeb, 2016: 434; Pessacq et al. 2019: 200.

Material examined. BR, TO: Rio da Conceiç „o municipality, Cachoeira Cavalo Queimado (-11.40366, -46.85849), 512 m, 15/ VI /2018, light sheet, MLS Rippel , TYS Orlando, AS Fernandes , R Boldrini , TK Krolow, 21 males .

Measurements. Male (n=8) forewing length: 8.8 mm – 10.0 mm (mean= 9.3 mm).

Remarks. The material from our study presents a considerable variation in size, as also observed in Bispo et al. (2005). The keel of the penial armature in our specimens is more truncate than triangular and the base is narrower ( Fig. 3E ) in comparison with the illustration of the holotype provided by Bispo et al. (2005), but we are considering these variations as intraspecific. Anacroneuria jaciara was found in a low order stream with cascades and a waterfall above the collection site. This is a new record from Tocantins state, Brazil ( Table 1 ).
