The present material of S. chadwickae is completely consistent with the original description, drawings, and photos of the species by Ďuriš & Horká (2016) . The rostrum length varies from reaching the middle to the end of the second antennular segment; the dorsal carina on the rostrum and carapace is long, nearly 0.7 as long as the carapace length; the orbital teeth completely cover the eye cornea from dorsal view and reach to about the midlength of the basal segment of the antennular peduncle; the first pereiopods are strongly asymmetrical in shape and unequal in size; the major cheliped carpus is produced into a stout subtriangular projection medio-distally; the palm bears a shallow depression dorsally and a deep proximo-ventral notch medially; the tip of the fixed finger is strongly upturned in about right angle and the telson bears a shallow median notch posteriorly. Coloration. Same as the type material, bright yellow across the entire body and appendages ( Ďuriš & Horká 2016: 780 , Fig. 7). Ecology. The Persian Gulf specimens were found beneath boulders semi-buried in sand in low intertidal and shallow subtidal zones. The type specimens from the north-eastern Red Sea were found in a similar habitat ( Ďuriš & Horká 2016 ). Distribution. Previously known only from the north Red Sea: Gulf of Aqaba ( type locality), and the south Red Sea (latter – not specified locality; see Ďuriš & Horká 2016 ). Newly recorded from the Persian Gulf, thus, the known range extended significantly (present report).
