( NMPC, SMNS) ; 2 specimens, same data, but: 25.ix.2005, at light, L. Borowiec lgt. ( NMPC) ; 2 specimens, Tamhini, 18°35.2′N, 73°18.2′E, 70m, 27.viii.2013, S.D. Sheth lgt. (HVGC); 3 specimens, Devi Hasol, 16°44.4′N, 73°25.9′E, 164 m, 1.ix.2015, at light, M.R. Kulkarni & S.V. Paripatyadar lgt. (HVGC).

Diagnosis. Medium sized (TL: 4.0– 4.5 mm), elongate oblong oval species. Elytra with broad transverse testaceous basal band, which does not reach suture ( Fig. 3 ). Head and pronotum with numerous longitudinal strioles. Elytra with 1 2–13 superficially impressed dorsal longitudinal striae, ending between two thirds and three fourths of elytral length; although 12 dorsal striae being reported in holotype ( Hendrich & Balke 1998), in most specimens, an additional short stria presented in basal third of elytra, laterally from stria 12. Median lobe unevenly curved in lateral view; outer margin slightly sinuate, subapically broad, abruptly pointed at apex ( Fig. 19 ). Parameres 'D'-shaped, apex very narrow and long; apical lobes long ( Fig. 20 ).

Collecting circumstances. Copelatus schuhi was found in an ephemeral water body, less than 10 cm in depth, with no vegetation ( Fig. 43 ); it is also occasionally attracted to light.

Distribution. The species is known so far from only three localities in Maharashtra ( Fig. 45 ).
