Key to distinguish males of Sogatella (modified from Asche and Wilson, 1990:7)

In the present study S. unidentata sp. nov. keys to couplet “4” in Asche and Wilson (1990) as follows:

3. Apex of clavus in forewing with dark brown marking............................................................................................................ .. 4

- Apex of the clavus without marking; parameres with apical margin undulate, shallowly concave, outer corner forming a pointed process............... S. capensis (Muir)

4. Parameres with inner and outer apical angles equally produced.................................................................................................... 5

- Parameres with inner angle strongly produced in a long digitiform process, outer angle rounded ( Fig. 8 )........................................... S. unidentata sp. nov.

5. Parameres strongly dilated at base with apex relatively small, almost equally bifurcate, diaphragm mediodorsally broadly U-shaped............... S. furcifera (Horváth)

- Parameres not dilated at base, apical part distally about as broad as base ( Fig. 3 ), U-shaped process of diaphragm rather narrow..................... S. nigeriensis (Jacobi)
