Type species: Euroleptochromus sabathi Jałoszyński, 2012 b (orig. des.). Diagnosis. Euroleptochromus differs from all remaining Leptochromini in the following unique apomorphies: maxillary palpomere II with short and broad submedian protuberance bearing apical bristles; and maxillary palpomere IV suboval and only about twice as long as broad. Additionally, a long cuticular process bearing apical bristles is present on each postgena (shared with some Leptochromus , but not with Rovnoleptochromus ). Composition and distribution. Euroleptochromus ( Fig. 111 ) comprises two extinct species known from the Upper Eocene Baltic amber. Remarks. Euroleptochromus , except for characters listed in the diagnosis, closely resembles Leptochromus in all remaining structures.
