Togoperla fortunati (Navás, 1926)

( Figs. 4–6 , 7B )

Material examined. 1 male ( USNM, T. grahami holotype), China: Sichuan Province, near Kuanshien (now Dujiangyan), Lin Ngai Si , 3500 ft, 1930.IX.20 , D.C. Graham; 1 male ( CAUC), Sichuan Province, Qionglai, Tiantai Mountain , 2012. VI.6, Junchao Wang; 4 males, 1 female ( CAUC), Sichuan Province, Emeihan City, Emeishan Mountain, Zero Kilometer , 1260 m, 2011. VI.29, Feiyang Liang; 1 male ( HIST), Sichuan Province, Emeishan City, Emeishan Mountain, Zero Kilometer , Longdong Lake , light trap, 2009. VI.30, Junchao Wang; 1 male ( HIST), same locality and collector, 2009.VII.2.

Remarks. The males from Qionglai have been identified as Togoperla sp. by the senior author and its mitogenomical results was analyzed by Wang et al. (2016). After we checked and compared with the holotype of T. grahami we believe that they are conspecific. The Sichuan materials have identical color pattern and external terminalia. However, the trilobed apex of aedeagal sac is more enlarged than that in holotype of T. grahami and the illustration in Stark & Sivec (2008: fig. 17), which may result from artificial eversion. The males from Qionglai also show a heavier hirsute areas of terga 6–8 and a distinct medial sclerite of tergum 9, together with darker habitus may indicate that these males are fully aged specimens.
