Etymology. Named after the type locality, Banten Bay in West Java, Indonesia.
Description. Based on holotype male, 5.09 mm, MZB.Cru.Amp 0 0 6.
Head. Eyes absent; with lateral cephalic lobes elongate, defined ventrally by a deep notch. Antenna 1 elongate, longer than antenna 2, approximately 0.75 times as long as body length; peduncle significantly shorter than flagellum; the length ratio of peduncle articles 1–3 close to 0.8:1.0:0.3, without robust setae along posterior margin; peduncular article 2 not geniculate; flagellum with 15 articles, accessory flagellum with 2 articles, shorter than first segment of antennal flagellum. Antenna 2 about a third length of antenna 1; peduncular article 2 gland cone not reaching to the end of peduncular article 3; article 4 slightly shorter than article 5; flagellum much shorter than peduncle and than article 5, with 3 articles. Upper lip is wider than deep, apical margin bearing fine setae. Lower lip inner lobes well-developed, with fine setae; outer lobes with apical setae; mandibular process weakly developed. Mandible symmetrical; palp, well developed, with 3 articles; article 1 much shorter than article 2, slightly longer than broad; article 2 subequal to article 3; Maxilla 1 inner plate with 3 long and 2 short plumose setae; outer plate with 8 robust setae; palp slightly exceeding tip of outer plate, slightly widened distally; article 2 longer than article 1, apically margin with 2 teeth and 4 slender setae. Maxilla 2 plates subequal, inner plate with apical and submarginal setae, with 5 plumose facial setae. Maxilliped outer plate not reaching far beyond the distal end of the second article of palp; palp 4-articulate, dactyl present.
Pereon. Gnathopod 1 coxa anteroventral corner slightly produced, rounded, anterior margin weakly concave, posteroventral corner notch absent; basis posterior margin with 3 long setae; merus without posterodistal tooth; carpus subequal in length to propodus, without anterodistal swelling; propodus palm acute, weakly convex, lined with 14 slender setae, without clear posterodistal corner and defining robust setae; dactylus well developed. Gnathopod 2 coxa broad, posteroventral corner notch absent; longer than broad with rounded corner; carpus short, broader than long; propodus expanded, palm slightly convex with sparse setae, dactylus closing along palm, inner margin smooth with sparse setae. Pereopod 3 coxa weakly produced posteriorly; basis, merus, carpus and propodus with medium-sized setae marginally. Pereopod 4 similar to pereopod 3. Pereopod 5 (regenerating and undergoing change) coxa broad, bilobated; basis linear oblong, posterior margin straight without castellation; carpus and propodus margin smooth without setae, dactylus broad and rounded with one small acute robust setae. Pereopod 6 coxa weakly lobated; basis oblong, posterior margin straight, minutely castelloserrate, posteroventral corner bluntly angular; carpus and propodus with medium-sized, slender setae along anterior margin. Pereopod 7 basis relatively narrowly expanded, with posterior margin strongly convex, minutely castelloserrate, evenly rounded posteriorly; merus posterodistal margin rounded, slightly expanded.
Pleon Pleonites 1–3 dorsally smooth, without dorsal spines or teeth. Epimera 1–3 posteroventral margin smooth; epimeron 2 with plumose setae; epimeron 3 with 1 small acute spine. Urosomites 1–3 without dorsal spines. Pleopods, peduncle with two retinaculae. Urosomite 1 without dorsal carina, without a small dorsal hump, smooth, without spines or gape. Urosomite 2 without small dorsolateral robust setae; posterior margin smooth; dorsally smooth. Urosomite 3 without dorsal setae. Uropod 1 peduncle with marginal spur, provided with 1 basofacial robust seta, with 1 dorsoexternal seta and 2 distolateral robust setae; rami with marginal spur, subequal in length. Uropod 2 peduncle with marginal spur, outer margin with 1 robust setae and 1 medium size robust seta distally; rami with marginal spur and robust setae on both sides, subequal in length. Telson with marginal spur, cleft, longer than broad, with a pair of short robust setae on the apex of each lobe.
Female. Sexually dimorphic characters, (Fig 5)
Gnathopod 1 merus rounded.
Gnathopod 2 palm acute, with a widely weak excavation in the half place and composed of two lobes, sculptured.
Pereopod 6 ischium posteroventral corner bearing 1 elongate robust seta exceeding merus.
Distribution. Indonesia. West Java: Banten Bay, Java Sea.
