Laufeia keyserlingi ( Thorell, 1890 ) : Simon, 1903: 824 ; Prószyński, 1984: 73–74 , 76. Type material. Syntypes : 1♂ 1♀ ( NHRS ; NHRS-TOBI000005483~NHRS-TOBI000005484) & 2♀ ( MSNG ), Indonesia : Sumatra , Singalang, 1878, leg. O. Beccari (Tobias Malm and Maria Tavano examined and shared the photos of syntypes ) . Diagnosis. Male resembles O. deelemanae sp. nov. and O. pakse sp. nov. in the relatively flat tip of RTA, but it can be distinguished from O. pakse by the relatively short RTA that does not extend beyond the tip of lobe-like protrusion of tegulum ( Fig. 129 ), and can be distinguished from O. deelemanae by the gentler prolateral margin of embolic disc in ventral view ( Fig. 275 ). Females can be distinguished from O. deelemanae sp. nov. by distance between atria is almost as long as diameter of atria ( Fig. 130 ; vs. in O. deelemanae sp. nov. the distance between atria is ca. three times longer than diameter of atria). Description. See Thorell (1890: 166–167) . Distribution. Indonesia (Singalang).
