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.
