ABSTRACT. Description of a new troglophilic species of Diplopoda collected in a cave on the island of Halmahera, Indonesia. This is the first identified stemm-iulidan encountered in this country, and also the first male taken from the «insular» part of the Indo-Pacific region where this order has hitherto been known only from two species, both described from female material from Papua-New Guinea. External morphological characters allow to distinguish the new species (which re-presents a case of obvious dimorphism) from the two Papuan congeners, but its gonopods, although showing some specific traits, fail to differ too significantly from the structural plan already known for this order. This supports the viewpoint that considers the genus-group taxa created by Silvestri [1897] (Diopsiulus), Silvestri [1916] (Prostemmiulus, Paurochaeturus, Plusiochaeturus) and Brolemann [1920] (Nethoiulus) as artificial, thus regarding them all as a single pantropical genus, Stemmiulus Gervais, 1844. Hence, with the proposal of the following new formal synonymy, Stemmiulus Gervais, 1844 = Diopsiulus Silvestri, 1897, = Prostemmiulus Silvestri, 1916, = Paurochaeturus Silvestri, 1916, = Plusiochaeturus Silvestri, 1916, = Nethoiulus Brolemann, 1920, syn.n., the entire order Stemmiulida appears to be represented only by two genera, Stemmiulus with more than 150 described species, and the monotypic Scoliogmus Loomis, 1941, from Puerto Rico.
