description: Key to the Afrotropical species of the genus Idiasta
The holotype of I. postscutellaris Szepligeti, 1908 (Tanzania) is missing from the Swedish Museum of Natural History in Stockholm where it was housed (H. Vårdal, Curator, personal communication) and original description of this species (Szepligeti, 1910) has not any characters allowing distinguish it from all other Idiasta species. As result, we have not included this species in our key.
