I emailed Bill Warner for confirmation that it's O. mcclevei. He replied, "It certainly looks like it...of course there could always be another new species floating around as many Orizabus are similar externally. Check the pecker vs. figs in my review(1)".

Per suggestion, I've added KOH cleared views of the paramera and tegmen. The key feature, "paramera with lateral tooth at about apical third" and its resemblance to Bill's Fig. 20 and Fig. 21 appear to confirm the ID. Note, though, the much steeper slope of the paramera's articulated joint with the basal segment seen in my specimen's lateral view. Bill's paper does not have corresponding images of the tegmen, but it might be worth taking a look. If someone can tell me which of my views of the tegmen is dorsal, I'll clarify the image titles.
