(figs 1 & 2). Female, 8.0 mm; immature judging by the under-developed oostegites. Pereon moderately inflated due to enlargement of pereonites 1–4. Head with short, hook-shaped rostrum. Eyes small or barely discernable. Antennae 1 as long as head and first 1.5 pereonites combined (measured medially). Antennae 2 similar in length to antennae 1, with relatively long, slender terminal article. Gnathopod 1; basis marginally shorter than remaining articles combined; carpus and propodus similar in length; propodus oval-shaped with numerous fine setae distally; dactyl relatively straight, length about half propodus. Gnathopod 2; length 1.4 x gnathopod 1; articles relatively more slender but of similar proportions to those of gnathopod 1; propodus with few long setae on margins and distally. Pereopod 3 marginally longer than pereopod 4; basis length almost 2.5 x merus; carpus slightly expanded with several moderate setae on distal margin, length about twice merus; propodus relatively narrow, length 1.4 x carpus; dactyl relatively straight, length slightly more than 0.2 x propodus. Pereopod 4 marginally shorter than pereopod 3 but of similar structure; basis length about twice merus, as long as carpus; propodus length about 1.3 x carpus. Pereopod 5 is relatively feeble compared to other pereopoda, with more slen- der articles except for the propodus; length marginally more than 0.7 x pereopod 4; basis length about twice merus; carpus length about 1.3 x merus; propodus length almost 0.9 x carpus, with tuft of three, slightly stronger, setae on anterodistal corner; dactyl relatively straight with bulbous base, length slightly more than 0.2 x propodus. Pereopod 6; length 1.1 x pereopod 5; basis length about 2.3 x merus; carpus length 1.7 x merus; propodus relatively narrow, slightly longer than carpus; dactyl relatively straight, length slightly more than 0.2 x propodus. Pereopod 7; length marginally more than 0.7 x pereopod 6; basis length 2.7 x merus; carpus length 1.6 x merus; propodus relatively narrow, length twice merus or 1.2 x carpus; dactyl relatively straight, length almost 0.3 x propodus. Uropoda with relatively slender peduncles and rami; all rami with slightly serrated margins. Uropod 1; peduncle marginally exceeds limit of peduncle of uropod 2, with strong seta on inner distal corner and about mid-way on inner margin; rami of similar length, about two-thirds peduncle. Uropod 2; peduncle with strong seta on inner distal corner; rami of similar length, about 0.8 x peduncle. Uropod 3; peduncle with seta as in uropod 2; inner ramus marginally longer than outer, length 0.9 x peduncle. Telson pointed; width at base almost 0.8 x length, slightly shorter than half of peduncle of uropod 3.
