First peduncular article very small, second about double in length of the first; third peduncular article 3 times longer than second, with a two ventral rows of long simple setae, each group with one long and one short seta. Fourth and fifth peduncular articles longest, nearly subequal in length, with similar setae pattern of the third article. Last peduncular article with a distolateral small feather-like seta. First flagellar article about twice as long as second and third flagellar articles together, bearing short bristles and one longer apical simple seta. Second article smaller and narrower than first, with many simple short bristles. Last flagellar article smallest, claw-like. The whole antenna covered with lots of short and small hairs (Fig.

PEREONITES. Pereonite 1 fused with cephalothorax, but separated by a ridge. Pereonite 2 only slightly shorther than pereonite 3; pereonite 4 longest. Pereonite 5 slightly shorter than pereonite 2, pereonite 6 and 7 smallest and shortest. Pereonite 1 with one pair of large dorsal spine-like tubercles, anteriorly directed. Pereonites 2-4 with two pairs of tubercles (one spine-like dorsal pair and one shield-like lateral pair). Dorsal pair of tubercles in pereonites 2-4 are large and high, apically flattened, covered with few hair-like small setae and small tubercle-like protrusions; in pereonites 5-7, these are smaller, more slender, apically acute, but with blunt tip and more laterally flattened. Lateral pairs of tubercles are large in pereonites 2-4, smaller in pereonites 5-7. Evident elevations separated by deep grooves characterise the surface of pereonites 2-4, between the dorsal and lateral tubercles. Elevations are also present on pereonites 5-7. However, these are more shallow, barely visible and uniformly covering the surface between the dorsal and lateral tubercles (Fig.

PLEOTELSON. All pleonites fused to pleotelson, frontolaterally of pleotelson two stout and slightly rounded protrusions, caudally directed (Fig. 2A, B and Fig. 3E). Pleotelson frontally broadest, narrowing caudally. Tip of telson acuminating, but with blunt tip, slightly rounded, slightly bent dorsally; subapical telsonic spines absent, but two pairs of rounded large tubercles in two rows in the pleotelson, dorsally; the pleotelson lacks spines, but is covered entirely by medium-sized rounded protrusions, slightly smaller laterally (Fig.

In dorsal view, these are long, divergent, forming a v-shape, reaching beyond the eyes. Pereonites 2-7 with only two pairs of tubercles: one dorsal pair of spine-like tubercles and one lateral pair of shield-like tubercles. Dorsal tubercles on pereonites 2-4 are large, apically flattened in lateral view, slightly anteriorly directed; on pereonites 5-7, these are smaller, slender, more pointed, but apically blunt and upwards directed. Pleotelson with blunt, strong protrusions.</paragraph>
