ZC. 2020.01.045, Failaka Island, eastern side, 29°23.409’N 48° 23.927’E, mixed rocky-muddy intertidal, muddy patches between rocks, depth less than 0.3 m, suction (yabby) pump, in burrow of ghost shrimp, Balsscallichirus masoomi, leg. A. Anker, 3 October 2019 [fcn KUW-068]. Description.Small-sized(cl 4.2mm)alpheid shrimp with not especially slender or compressed body.Carapace covered with fine erect setae(Fig.1A, B). Rostrum well developed, broadly subtriangular, slightly longer than wide at base, acute distally, slightly overreaching mid-length of second article of antennular peduncle; lateral margins feebly concave proximally; neither rostral nor mid-dorsal carina present (Fig. 1A, B). Orbital teeth well developed, sharp distally, directed slightly mesially in dorsal view, anteriorly in lateral view (Fig. 1A, B). Pterygostomial region broadly rounded; anterolateral suture present (Fig. 1B); cardiac notch well developed. Each epistomial sclerite with stout acute process. Pleon with first to fourth pleura broadly rounded to slightly angular; fifth pleuron with posteroventral margin produced into acute, posteriorly directed tooth; sixth pleonite without articulated flap, with short, partly internal suture, posterior margin produced into short subacute tooth flanking telson (Fig. 1C); preanal plate posteriorly rounded. Telson moderately slender, subrectangular, tapering distally, almost 2.5 times as long as maximal (proximal) width; dorsal surface with two pairs of small cuspidate setae both inserted at some distance from lateral margin, first pair at about telson mid-length, second pair at about 0.8 of telson length; posterior margin with small shallow notch flanked by with two long plumose setae, remaining margin from central notch to posterolateral angle straight, with two pairs of robust spiniform setae, mesial ones much stouter and about 1.5 times longer than lateral ones (Fig. 1D, E).
