Tanypus Meigen

( Fig. 4 )

Tanypus has been reported from the region previously only as T. punctipennis Meigen by Johannsen (1931) from Sumatra, with the larva and pupa described briefly by Zavrelˇ (1933).

Known biologies within this worldwide genus suggest that the larvae are predatory in warm shallow pools, especially those with high nutrient loadings. The four larval records in this study come from ponds with conductivities ranging from dilute (49 and 103 to more saline 727 and 4,440 µS. cm−1) and with a similar wide range in dissolved solid concentrations (24, 51 364, 2,230 ppm).
