Okanagrion incertae sedis

Figs. 42–43.

Material. SR 11-60-17AB (Fig. 42), collected at Republic A0307 by Karl Volkman, 15.vii.2006, housed in the Stonerose Interpretive Center collections; SR 94-05-30 (Fig. 43), collected at Republic A0307 B by Wes Wehr, 31.x.1994 and SR 11-51-07AB (Fig. 43) collected at Republic B 4131 by Dennis Vickerman, 22.viii.2008, both in the Stonerose Interpretive Center collections; SR 06-08-18 (Fig. 42), collected at Republic B 4131 by Don Volkman, 4.vi.2004, in the Stonerose Interpretive Center collections; UWBM-74307 (Fig. 42), collected at Republic A0307 B by Wesley Wehr, 1993, in the Burke Museum collections; RBCM P1550, three wing portions (Fig. 43) collected by John Leahy at the McAbee Hoodoo Face beds, unknown date, in the Royal British Columbia Museum collections .

Discussion. SR 11-60-17: The dense crossvenation and colouration indicates that this specimen belongs to one of the infuscate Okanagrion species. SR 94-05-30 and SR 11-51-07: these two apical-anterior wing fragments could belong to any Okanagrion species that are infuscate in this region, although SR 94-05-30 does not belong to O. lochmum by its crossvenation in the RA–RP1 space. SR 06-08-18: colouration indicates that this specimen belongs to one of the infuscate Okanagrion species; the light fascia, although poorly preserved, suggests O. threadgillae . UWBM-74307: the infuscation does not reach the nodus as in some Okanagrion species, and IR2 originating on RP1-2 restricts it within these to O. beardi, O. dorrellae, and O. angustum . Many crossveins are closer together than in any of these, however. RBCM P1550 belongs to an infuscate species, although this is preserved too poorly to clarify which one; IR2 originates rather evenly between RP1-2 and RP3-4, ruling out O. beardi; and it is neither O. dorrellae nor O. augustum by shape. It likely either belongs to O. hobani or to O. lochmum; the CuA–A space five or six cells wide is consistent with these.
