Notes

Grichanov & Mostovski (2009) examined male and female types of Thinophilus bipunctatus (NMSA) and noted that there are no principal differences from the description of T. maculatus , and the two names may be synonyms. Thinophilus bipunctatus was previously recorded from DR Congo, Namibia, and South Africa, usually from wet material (in ethanol). Unnoticed in the original description, its types have a distinct prescutellar spot in addition to six lateral spots on the mesonotum. Thinophilus maculatus was previously recorded from Gabon, Namibia and South Eastern Desert of Egypt, sometimes from females only. Both species were in fact found in the same countries as widely distributed and common T. indigenus Becker, 1902 . The key characters formerly used included only colour characters, e.g., the number of dark spots on the mesonotum ( Parent 1936; Grichanov 1997). The rather abundant material examined shows that this feature is variable and invisible on wet specimens. The male genitalia examined are identical in all listed specimens, corresponding with the pictures of T. indigenus from Iranian Baluchistan published by Negrobov (1978). Therefore, I consider all three names as synonyms.

Thinophilus indigenus was mentioned by Rossi & Leonardi (2018: 111), as a host for the Laboulbeniales fungus Stigmatomyces ligabuei W. Rossi, 1986 , found in Sierra Leone and Sudan.
