Material. Republic: SRUI 99-72-96AB ( Fig. 58 ), collected at Republic B 4131 by Rita Weikel, 27.iv.2019, housed in the Stonerose Interpretive Center collections; SRUI 99-97-44 ( Fig. 58 ), collected at Republic A0307 by Wes Wehr, date unknown, in the Stonerose Interpretive Center collections; F-1046 ( Fig. 58 ), collected at McAbee, collector and date unknown, in the Thompson Rivers University collections; UWBM-72324 ( Fig. 60 ), collected by Wes Wehr at Republic A0307 , date unknown, in the Burke Museum collections; SR 13-005-015 AB ( Fig. 59 ), collected at Republic B 4131 by Richard Dillhoff, 6.v.2008, in the Stonerose Interpretive Center collections; GSC 141103 ( Fig. 59 ), collected at the McAbee Hoodoo Face beds, Geological Survey of Canada locality code V-016800, by SBA, July 31 2000, in the Geological Survey of Canada collections; RBCM P1553 ( Fig. 60 ), collected at the McAbee Hoodoo Face beds by John Leahy , date unknown, in the Royal British Columbia Museum collections .

Discussion. These wing fragments of varying size appear to belong to one of the defined species of Okanopteryx by their distinctive colouration and all other preserved morphology, but diagnostic character states separating these species are not preserved. For example, F-1046 agrees with the O. macabeensis holotype in all aspects, e.g., just over 14 mm nodus to pterostigma, but lacks almost the entire CuA–A space. The preserved region of specimen SR 13-005-015 AB is almost identical to that of the more complete O. jeppesenorum SR 02-32-23, also from Republic exposure B4131.
