ID'd with the help of Phillip Harpootlian. Sutural striae end at the scutellum which excludes G. hornii and G. balyi. Punctate striae exclude G. semiopacus. Body is very broad, almost circular, as compared to the more elongated G. blackburnii (look at how the distance between the humeral angles is about equal to the total length of the elytra). G. splendidus can also be rather broad, but not quite so much as G. egeriei and is usually more brightly colored.
