We report time-resolved optical CCD photometry on newly discovered SU UMa-type dwarf novae , FL TrA and CTCV J0549-4921 .
During the 2006 August outburst , we detected superhumps with a period of 0.59897 ( 11 ) days for FL TrA , clarifying the SU UMa nature of the system .
On the first night of our observations on FL TrA , the object showed no superhumps .
This implies that it takes a few days for full development of superhumps .
The superhump period variation diagram of FL TrA was similar to that observed in some WZ Sge stars and short period SU UMa-type stars .
This indicates that the system is closely related to WZ Sge stars and SU UMa stars having short orbital periods .
For CTCV J0549-4921 , the candidates of the mean superhump period are 0.083249 ( 10 ) days and 0.084257 ( 8 ) days , respectively .
Due to a lack of the observations , we can not determine the true superhump period , but the latter period is favorable .
Using the ASAS-3 archive , it turned out that the system shows only four outbursts over the past 6 years .
The outburst amplitude of CTCV J0549-4921 was relatively small , with about 4.5 mag .
One possibility is that mass evaporation may play a role during quiescence .
