This species, widespread in East and South-east Africa ( van Bruggen and van Goethem 1997 ) was much more frequent in non-forest habitat types than in forest (Table 2). Voeltzkow (1923) recorded " Gulilla laevigata (Dohn)" (sic); Haas (1929) recorded Gulella laevigata (Dohrn) from Chake Chake. The record probably actually refers to Gulella planidens (see van Bruggen and van Goethem 1997 ). Figures 64-75.
