Notes. ZABRANSKY (2004) placed the species from Socotra into the newly described subgenus Svatacesta Zabransky, 2004   within the mainly Oriental genus Strigoptera Dejean, 1833   [nine species in the Oriental region and a single Afrotropical species S. bettoni (Waterhouse, 1904)   from coastal East Africa]. P. Zabransky (pers. comm.) based this decision on a “broad” concept of the taxonomic composition of the genus Strigoptera   (sensu lato). However, the study of the paratypes of S. (Svatacesta) socotra   has shown that this species actually belongs to the Afrotropical genus Pseudocastalia Kraatz, 1896   .

The principal diagnostic character of Pseudocastalia   is the laterally deeply emarginated pronotal and elytral bases ( Figs. 1–4, 6 View Figs ) and the opening the apical part of the mesepisterna appearing like teeth from above ( COBOS 1980, HOLM 1982); in Strigoptera   the pronotal and elytral sides are contiguous or shallowly emarginated. Another important character is the presence of a short rudiment of AA3a’ vein on the wings ( Fig. 12 View Figs ) (terminology follows FEDORENKO 2009), while in Strigoptera   this rudiment is lacking ( Fig. 13 View Figs ). Another reliable character to distinguish these genera is a lateral serration of the penis, well marked in Strigoptera   ( Fig. 21 View Figs ) and completely lacking in Pseudocastalia   ( Fig. 19 View Figs ). Finally, the shape of apical abdominal ventrite in males of Pseudocastalia   ( Fig. 10 View Figs ) differs from that in Strigoptera   ( Fig. 11 View Figs ). In accordance with this character set, S. socotra   is transferred to the genus Pseudocastalia   and the genus level name Svatacesta   is treated as a junior subjective synonym of Pseudocastalia   . The placement of this species into a separate subgenus is unwarranted.

Although all the specimens of P. socotra   have been reared from wood, its host plant is still unknown.
