( Fig. 12 )

Hister tenuistriatus Lewis, 1889: 284 (type locality: Borneo).

Atholus tenuistriatus : Lewis 1906: 402 (listed); Mazur 1984: 217; Mazur 1997: 133; Mazur 2011: 106 (catalogued).

Hister (Atholus) tenuistriatus : Bickhardt 1910: 55; Bickhardt 1917: 194 (catalogued); Desbordes 1917: 319 (keyed).

Specimens examined. No specimen available for this study.

Diagnosis. Atholus tenuistriatus can easily be recognized for its two pronotal lateral striae, which is a rare characteristic among the Oriental Atholus . Although this character-state was also recently observed in A. lao Mazur, 2013 , the external pronotal stria in A. tenuistriatus is longer and almost complete compared with A. lao . The elytral sutural stria of this species is almost complete, while both of its propygidium and pygidium are almost impunctate, the pygidium particularly is smooth.

Distribution. Indonesia: endemic to Borneo Island ( Fig. 12 ).
