Paratypes ( 73 specimens): 27 ♂, 39 ♀, same data as holotype ( ISNB, MFNB) ; 1 ♂, Siem Reap, town area ( 13°21′18′′N, 103°51′19′′E), 4.I.1998 ( MFNB) GoogleMaps ; 1 ♂, Pnom Penh , leg.

Description: Male: Abdominal sternite VII (Figs 22, 24) with black, lateral combs of posterior emargination occupying almost 0.4 of maximum sternite length and straight at distal end; corona of black setae surrounding posterior emargination well developed.

Abdominal sternite VIII (Figs 23, 25) with medially divided field of black macrosetae short, occupying only median third of sternite length.

Aedeagus with apical lobes in apical portion narrow,strongly lengthened distad, each ending in long, ventrolaterad curved apical tooth ( Figs 48, 49, 51, 52 View FIGURES 48–53 ); subapical teeth acute, pointing lateroproximad, not projecting from ventral margin of apical lobes ( Figs 48, 51 View FIGURES 48–53 ), but strongly projecting laterally ( Figs 49, 52 View FIGURES 48–53 ); membranous lobes both projecting ventrally and laterally ( Figs 48, 49, 51, 52 View FIGURES 48–53 ); ventroproximal ends of apical lobes elongated to triangular, subacute angles ( Figs 48, 51 View FIGURES 48–53 ), in ventral view running close to each other and pointing medioproximad ( Figs 49, 52 View FIGURES 48–53 ). Ventral lobe barely protruding ventrally, in lateral view without pointed apical end ( Figs 48, 51 View FIGURES 48–53 ), in ventral view in lateral sixths of width deeply, convexly emarginate, in median two-thirds of width dilated laterodistally with obtusely right-angled laterodistal angles and between them concave with short, median emargination ( Figs 49, 52 View FIGURES 48–53 ). Length of aedeagus: 0.59–0.6 mm.

Female: Bursa with ends curved dorsad with even, concave curve; bursa in distal half strongly, gradually dilated dorsad towards subtruncate, convex end, in proximal portion narrow and subparallel in lateral view, but strongly, convexly widened laterally, thus clavate in ventral view ( Fig. 61 View FIGURES 54–61 ).

Distribution: Scopaeus kritschi is known only from northern Cambodia ( Siem Reap) and central Laos (Fig. 62), but expected to be distributed in Thailand and southern Vietnam as well.

Etymology: I dedicate this new species to Daniel Kritsch, Fulda (epithet kritschi : Latinized noun, derived from the surname Kritsch, genitive, singular).
