Descriptions

Diagnostic description

Very common species in the Afrotropical region with yellow markings on abdomen reaching the lateral margins (Fig. 1A, C). Males of I. aegyptius have metatrochanters with a long calcar (Fig. 1E) (short calcar in I. scutellaris) and the claws of the fore leg are asymmetrical (as in Fig. 5F) (males of I. feae also have asymmetrical claws but they do not have a calcar on the metatrochanters). The male genitalia are quite unique with a trilobed surstyli (Fig. 1F). Females are very difficult to distinguish from females of I. scutellaris as the pattern of tergite 2, very often used to distinguish them (Sack 1932, Huang and Cheng 2012, Speight and Sarthou 2017), is variable. At this moment, conspecific males, DNA barcodes and/or collecting locality may help to distinguish them.
