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.
C. 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.
C. strandi has been described on specimens of the Eritrean coast and of the facing coast of Yemen. It is so present on both the southern coasts of the Red Sea and of the Gulf of Aden. Moreover it spreads along the Indian Ocean coasts of Somalia and eastern Kenya and it penetrates in southern Ethiopia.
