Dichtha

The white-legged toktokkies (genus Dichtha) are ground-dwelling, Afrotropical beetles in the family Tenebrionidae.[2] They are stout, black beetles of about 2 – 2.5 cm in length. The antennae and legs are covered in pale[3] to brownish[4] down. Like the related genus Psammodes, the adults tap out a rhythm on the ground to attract and locate mates. They feed on both plant and animal material.[3] Some species, like D. inflata, may feign death.[4]

Species

The species include:[5]

A catalogue of the Sepidiini tribe from 2019[5] considers Dichtha incantatoris Koch, 1952 a nomen nudum and therefore invalid. A likely source of this erroneous name is the popular Field Guide to Insects of South Africa by M Picker, C Griffiths & A Weaving. Specimens identified under this name are likely Dichtha cubica (see this explanation by iNaturalist curator Riaan Stals).
