Zavreliella Kieffer

( Figs. 21, 25 , 26 )

Two larvae belonging to Zavreliella were found in dilute unimpacted, non-peaty pools of conductivity 77 and 180 µS. cm−1 and dissolved solids of 38 and 90 ppm, respectively. Zavreliella marmorata (v.d.Wulp) has been reported from Indonesia ( Reiss, 1990) and pupal exuviae of the genus have been reported from Sulawesi ( Ashe, 1990).
