To evaluate \(-\left(\frac{2}{5}\right)^2\):

1. Square the fraction \(\frac{2}{5}\):
   \[
   \left(\frac{2}{5}\right)^2 = \frac{2^2}{5^2} = \frac{4}{25}
   \]

2. Apply the negative sign:
   \[
   -\left(\frac{4}{25}\right) = -\frac{4}{25}
   \]

So, \(-\left(\frac{2}{5}\right)^2 = -\frac{4}{25}\).
