Metapectal-propodeal disc reticulate rugose, with transverse keels; propodeal declivity reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands. In specimen from Kenya, Kasigau Mtn., forewing with small dark spot around 2r-rs&Rs vein. Protrochanter approximately 4 × as long as broad.

(Solms) (Pontederiaceae)).
Distribution. Botswana, Burkina Faso, Cameroon, Cape Verde Islands, Democratic Republic of the Congo, Ivory Coast, Kenya, Madagascar, Mali, Mozambique, Niger, Oman, Senegal, Sierra Leone, Somalia, South Africa, Tanzania, Uganda, United Arab Emirates, Yemen, Zimbabwe, in addition to Egypt (Palaearctic).
Remarks. Echthrodelphax migratorius was recorded by mistake from many further localities in Yemen (Olmi & Van Harten 2000, 2006). These records (all ♂♂) are actually of E. tauricus (see below). The unique locality in Yemen, where E. migratorius was definitely collected (one ♀), is Qa Al Boun (see above).
