Exocelina bagus MB4915: Toussaint et al. 2014 : Supplementary figs 1-4, Tab. 2. Type locality. Papua: Nabire Regency, 54-55 km of road Nabire to Enarotali, ca. 03°29.80'S ; 135°43.89'E . Note: the road only goes up to Enarotali, Ilaga is much further in the mountains, therefore, people now refer to the road as Nabire-Enarotali. Type material studied. Holotype: male "IR90-11: W. New Guinea, Trek Nabire-Ilaga, km55, 19.-25.ix.1990, Balke", "HOLOTYPUS" [red], " Copelatus speciosus sp.n. Balke des. 1997" [red] (NHMW). Paratypes: 9 males, 12 females with the same label as the holotype (NHMW). 6 females "W.-Neuguinea/Paniai Prov.
