Type specimen examined: Holotype , Kalimantan Barat , Pontianak; labeled ‘Type’ (round, printed label with red margin), ‘Pontianak / Borneo’ (handwritten), ‘S. / borneensis / TYPE Cam .’ (handwritten), ‘M. Cameron./ Bequest./ B.M.1955-147.‘ (printed), ‘ Holotype / Scopaeus borneensis / Cameron 1941 / label by J. Frisch, 2022 ’ (red, printed) ( NHML ). Cameron (1941: 229) described Scopaeus borneensis based on a ‘unique’ specimen. Thus, it is a holotype by monotypy ( ICZN , Article 73.1.2) . Redescription: Habitus and coloring as in Fig. 26 . Head subquadrate. Penultimate antennal segment slightly elongate. Mesotibia moderately thickened. Body surface subnitid, finely, densely punctate, without microreticulation. Pubescence of body surface short, decumbent, without conspicuous macrosetae. Forebody reddish dark brown; abdomen and antennae medium brown; maxillary palpi and legs light brown. Total body length 3.8 mm ; forebody length 2.4 mm . Male: Unknown. Female: Chamber segment of sperm pump short, without apophysis, acute-angled attached to distal process with strongly widened apex ( Fig. 181 ); bursal duct strong, with S-shaped portion gradually widened, then strongly narrowed towards sperm pump ( Fig. 180 ).
