Additions to the original description. Habitus ( Figs. 105–106 ); body length 6.0–10.0 mm (for a photo of the holotype see ZOIA 2012)

Prothorax usually with a small, oblong median impunctate area. Scutellum ( Fig. 7 ) moderately wide, nearly rectangular, with lateral sides almost straight and feebly widened from base toward rear, distal border curved, or with very wide angle in middle. Elytral punctation finer than on prothorax, dense, confuse, partially confluent, with exception of three more or less evident longitudinal thin stripes with finer punctures and smooth surface. Notosternal suture evident and deep anteriorly, scarcely visible posteriorly. Claws bifid starting from their midlength, with short inner tooth.

Aedeagus as in Figs. 1–2 .

Spermatheca as in Fig. 5 ; coxites ( Fig. 6 ) moderately sclerotized in their distal portion, spiculum ventrale moderately long and thin, vagina without any sclerotization.

Comments. The species is also reported from Abd el Kuri by GAHAN (1903). I had not the opportunity to examine material from that island, nevertheless the assertion that ‘the examples ... differ slightly from those found in Socotra, in as much as they show no trace of the coppery tint present on the upperside in the latter’ gives rise to doubts that they might belong to a different species.
