Diagnostic notes.

The subgenus Parasphingonotus Benediktov & Husemann, 2009 is characterised by a serrated radial vein that is raised above the subcostal vein. Thickened cross veinlets between the radial and medial veins are absent ( Husemann et al. 2011). Sphingonotus (P.) turkanae is a relatively small member of the genus (Figs 79 View Figure 79 , 81 View Figure 81 ), lacking a dark fascia in the hind wings, with a short, strongly trilobate supra-anal plate with raised tubercles ( Husemann et al. 2011).

Distribution and occurrence.

The type locality of Sphingonotus (P.) turkanae is Lake Turkana in Kenya. The species is restricted to eastern Africa ( Ethiopia, Somalia, Kenya, Tanzania) and Yemen, including Socotra (Fig. 80 View Figure 80 ) ( Husemann et al. 2011). Husemann (2020) mentioned only Ethiopia, Tanzania and Kenya.

Habitat and biology.

On Socotra, the species can be found in various habitats between 5 and 500 m a. s. l., mostly in sparse dwarf shrubland, low Croton - Jatropha shrubland and submontane grassland. At Taaqs, it was found on a fine, gravelly plain with grassy vegetation (Fig. 4 View Figure 4 ), at Dehamd on a coastal plain and at Ayhaft on gravelly soils in a Frankincense forest. Records are from all seasons.

Bioacoustics.

Members of the Oedipodinae subfamily are known to emit quiet, buzzing sounds during rivalry, courtship and flight ( Roesti and Keist 2009). The sound of this species is unknown.
