Macrostemum luteipes Kimmins, 1955

( Figs. 123–125 )

Macrostemum luteipes Kimmins, 1955: 388 [Holotype male; Malaysia; BMNH].

Distribution. Borneo.

Remarks. A specimen had been borrowed from UM; however, the specimen labeled under the name of M. luteipes was found to be misidentified and was in fact M. distinguendum . Therefore, specimens of M. luteipes were not observed and genitalia ( Figs. 123–125 ) were redrawn from Kimmins (1955: Figs. 54–56 ).
