Adults are on the wings through the year and fly at elevations from 400 to 2000 m(Plate 4C–4D).   Distribution. Taiwan.   Remarks.  T. brunneawas transferred to the genus  Ocinara Walker, 1856by Strand (1922)and  Ocinara diaphragma formosana Mell, 1958was synonymized with it by Dierl (1978). In the Sapporo Museum, we checked the specimens bearing labels with the name “  Ocinaria taiwanaMatsumura” from Baibara in Formosa(Central Taiwan), but we have been unable to locate a published description of this name; however, as the specimen ( Fig. 9A, 9B) was collected in 1925 the name, if published would postdate,and thus be a junior synonym of  brunnea. Chu & Wang (1993, 1996) incorrectly synonymized  Triuncina cervina( Walker, 1865)with  Ocinara brunneaand placed it once again in genus  Ocinara. However,  T. cervinais a valid species endemic to Nepaland unknown so far from Mainland Chinaand Taiwan.  13.  Triuncina xiongiWang, X. & Zolotuhin,  sp. nov.( FIGURES 10A, 10D)    Ocinara brunnea Wileman, 1911: Chu &Wang, 1993, Sinozoologia, 10: 229; Chu & Wang, 1996, Fanuna SinicaInsect, 5: 39.
