Omobrachyiulus tnesorientalis sp.n., the first record of the millipede genus Omobrachyiulus Lohmander, 1936 in the Near East (Diplopoda: Julida: Julidae: Brachyiulini)

摘要

The first species of Omobrachyiulus is described from Israel and Lebanon: O. mesorientalis sp.n. This new and yet sole Near East species of the genus is distinguished from congeners both in certain morphological characters, primarily gonopodal ones, and in likely representing one of the southernmost outliers not only of its mostly Caucasian genus, but also of the entire, largely circum-Mediterranean tribe Brachyiulini it belongs to. Palaeogeographic evidence dating back to the Eastern Paratethys in the Miocene and Pliocene is brought up to possibly explain the modern distribution pattern of both Omobrachyiulus and O. mesorientalis sp.n.
