Type material.

Holotype male: Borneo, W. Kalimantan, Gunung Palung Nat. Pk., 15 June-15 Aug. 1991, Darling, Ubaidillah (Rosichon), Sutrisno, 11S 910131 (MBBJ).

Paratype: 1 male, same data as holotype, 11S 910125 (BME).


This species has a number of distinctive features that in combination will distinguish it from other Loboscelidia  , including the scale-like setae on the head and legs and the scrobal sulcus reduced to a series of foveae.
