Hister javanicus: Ohara, 1989, 38 [diagnosis]; Mazur, 1997, 113.
Hister squalidus: Ohara, 1989, 43.
Diagnosis based on the Taiwanese material. Biometric data as follows (in mm)(Figs. 28-30) (Ohara, 1999):
PPL 6.25, PEL 4.9, APW 1.65, PPW 3.75, PL 1.95, EL 2.65, EW 4.35, ProW 2.6, ProL 1.0, PyL 1.3, PTL 1.3, MSTL 1.25, MTTL 1.65. First to 4th dorsal elytral striae complete (Fig. 28B). Fifth stria present on apical third, and sutural stria on apical half. Propygidium (Fig. 29C) irregularly and sparsely covered with coarse and deep punctures, which are separated by half their diameter to ten times the diameter. Pygidium convex medially, and deeply and coarsely punctate, the punctures separated by half to three times their diameter and becoming finer apically. Protibia (Fig. 28D, E) with 2 denticles on outer margin.
Specimens examined.
[Proper] Kaoshiung Hsien: Chuyunshan, Logging road, 35 km (1 male., 23/x/1995), Y.Y. Lien.
Distribution. Taiwan; Java; eastern India; nearly the whole Oriental region, introduced to Africa. New to Taiwan.
Remarks. The number of denticles on the outer margin of the protibia is usually three in this species, but in the material of Taiwan it is only two.
