Pseudochromis sankeyi Lubbock, 1975: 145  , pl. 2, fig. d (type locality: Massawa, Ethiopia, Red Sea); Gill, 2004: 169, fig. 42, pl. 11 I (description, synonymy, distribution, colour photo).

Gill (2004) recorded P. sankeyi  from the southern Red Sea, Golfe de Tadjoura ( Djibouti) and Yemeni coast of the northern Gulf of Aden. We record it from the Socotra Archipelago on the basis of six specimens from Socotra Island. The specimens agree well with those from other localities.

Pseudochromis sankeyi  was visually recorded from four additional sites in 1999-2000, including two records from Abd al-Kuri Island (including the rock islets of Kal Farun north of it). The species thus appears to occur throughout the entire archipelago, although it has not been recorded from Darsa and Semha, which are situated between Socotra and Abd al-Kuri. The species was rarely observed, despite its conspicuous colour pattern and ready visual identification. It was also rarely observed during subsequent surveys in 2009-2011 by H. Pulch, T. Alpermann and U. Zajonz. It was mainly recorded from the north coasts from hard coral communities including those dominated by Millepora  and Porites  , and encrusting and massive Agariciidae  , Pectiniidae  , and Mussidae  , as well as from mixed communities of macroalgae and hard corals on rock platform and mixed encrusting communities on exposed rock platform, and a near vertical rocky drop off. Its depth range on Socotra (5–42 m) is wider than that of most other species.
