Anyone know the current whereabouts of Sule Oygur or G. W. Wolfe (or is either person on this list)? They authored the paper "Classification, distribution, and phylogeny of North American (North of Mexico) species of Gyrinus Muller (Coleoptera: Gyrinidae), pulbished in American Museum of Natural History 207. 1991.
