Remarks.

Depicted in Ahl (1931b: 422, fig. 295). From October 1914 until the end of 1915, the German zoologist and colonial officer Prof. Dr. Friederichs, who was a prisoner of war during the First World War, collected in the courtyard of the French Fort Duchesne (on a hill opposite of Antananarivo, ca. 1400 m a.s.l.). Later, he continued collecting until 1916 on Kap Diego [Cap Diego, Antsiranana I District, Diana Region, Diego Suarez Province] in northern Madagascar ( Schultheß 1918; Friederichs 1919).
