Diagnostic notes.

Sphingonotus (Sphingonotus) rubescens (Walker, 1870) has a pattern of relatively small dark spots on the tegmina with less clear transverse bands, hyaline hind wings and a characteristic strongly S-shaped intercalary vein ( Mistshenko 1937).

Distribution and occurrence.

It is widespread in northern Africa, southern Europe, Arabia and parts of Asia ( Husemann 2020; Dey et al. 2021). It was newly reported for Socotra based on one specimen collected in 2010 ( Dey et al. 2021). We found one specimen in Wranik’s collection from Samha, 1999 (Fig. 100 View Figure 100 ).

Habitat and biology.

On Socotra, one specimen was found on a gravelly slope at 150 m a. s. l. near Hadiboh.

Bioacoustics.

The song of this species consists of whistling and ticking sounds (e. g. Baudewijn Odé, XC 786864, accessible at https://www.xeno-canto.org/786864) and is described by Bland (1985).
