Calosoma (Ctenosta) strandi Breuning, 1934

Calosoma (Ctenosta) Strandi Breuning, 1934: 38 (Typus: Masaua (Massawa); coll. Breuning, Naturalis Biodiversity Centre, Leiden)
Ctenosta Strandi Jeannel, 1940: 130


Length 26-30 mm. The sculpture of elytra in this species, as in planicolle and senegalense, is characterized by intervals deeply incised and that have different width and heigth ("hétérodyname" sculpture of Jeannel). But in strandi, both the secondary and tertiary intervals are more elevated and larger than the primary ones.
strandi can also be distinguished at first glance by the dark bronze color of the upper body where the primary intervals are lively bronze. The metatrochanter have a rounded tip in both sexes.
It is found in Erithree, in the Ogaden region of Etiopia (Gabredarre = Kebri Dehar, Jeannel 1940:130), in Somalia and northern Kenya.
