We report long-term and time-resolved photometric observations of the dwarf nova HS Vir (=PG 1341-079). Time-resolved photometry during the bright outburst in 1996 March revealed superhumps with a period of 0.08059±0.00003 days, which first firmly confirmed HS Vir as a genuine member of SU UMa-type dwarf novae. HS Vir is rather unusual in the smallness (2.7-3.5 mag for brightest superoutbursts) of outburst amplitudes. The marked diversity inferred from the comparison with SX LMi may reflect different mechanisms responsible for the smallness of outburst amplitudes in these dwarf novae.
