The white-legged toktokkies (genus Dichtha) are ground-dwelling, Afrotropical beetles in the family Tenebrionidae.{{cite web |title=Dichtha cubica |url=http://www.ubio.org/browser/details.php?namebankID=2895640 |work=MBLWHOI Library |publisher=uBio |accessdate=13 May 2013}} They are stout, black beetles of about 2 – 2.5 cm in length. The antennae and legs are covered in pale{{cite book|last=Picker |first=Mike|title=Field Guide to Insects of South Africa |url=https://archive.org/details/fieldguidetoinse00grif |url-access=limited |year=2004 |publisher=Struik Publishers |location=Cape Town |isbn=978-1-77007-061-5 |pages=[https://archive.org/details/fieldguidetoinse00grif/page/n228 230]–233|display-authors=etal}} to brownish 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. Some species, like D. inflata, may feign death.{{cite book |last1=Morris |first1=Brian |title=Insects and Human Life |date=2006 |publisher=Berg |isbn=9781845209490 |page=251}}

A catalogue of the Sepidiini tribe from 2019 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 [https://www.inaturalist.org/taxon_changes?taxon_id=662079 this explanation by iNaturalist curator Riaan Stals]).
