Similar Taxa

Similar to Schizotetranychus cynodonis Mc Gregor and Schizotetranychus parasemus Pritchard & Baker, except S. gahniae has empodia lacking proximoventral hairs, a hooked peritreme, differing leg chaetotaxy and a differently shaped aedeagus (Davis 1969).

Biology

The mites are found on the ventral surface of the leaf blades, in small colonies each protected by its own closely woven silken cover or sheet of webbing.  Eggs are laid in single file, in rows of up to 16 (pers. obs.) and are individually covered in a silken patch.
