(Fig. 6)
Description. FEMALE (holotype, range for 3 paratypes) (Figs. 6 A–E). Total body length 686 (628–634). Gnathosoma. Infracapitulum apunctate. Stylophore apunctate, 218 (214–220) long. Each medial branch of peritremes with 4–6 chambers, each lateral branch with 8–11 chambers. Idiosoma. All dorsal setae, except for f1 and f2, thick and distinctly knobbed. Propodonotal shield entire, well sclerotized. Setae ve situated postero-lateral to vi. Length ratio of setae vi: ve: si 1:1.1–1.5:2.8–3.5. Bases of setae c1 and se situated at same transverse level. Hysteronotal shield reduced to two small sclerites surrounding bases of setae d1. Setae d2 and e2 subequal in length, both pairs slightly longer (1.1–1.2 times) than d1. Length ratio of setae ag1: ag2: ag3 3.8–4.9:1:4.5–5.3. Two narrow and weakly sclerotized agenital plates situated above ag1 setal bases. Genital plate absent. All coxal fields apunctate; setae situated on coxal fields III and IV thick and distinctly knobbed. Genital and pseudanal setal series represent by one pair of microsetae, each. Legs. Solenidia ωI longer than σI and φI. Lengths of setae: vi 52 (41–45), ve 57 (61–63), si 145 (132–150), se 198 (167–195), c1 216 (218–230), c2 228 (232–248), d1 155 (157–171), d2 173 (163–193), e2 191 (155–182), f1 41 (38–45), f2 93 (91–100), h1 25 (25–30), h2 (532–557), g1 and ps1 (6–9), ag1 207 (200–227), ag2 55 (30–52), ag3 250 (230–275), 3b 59 (48–54), 3c 105 (93–109), 4b 88 (64–67), 4c 125 (107–127).
MALE. Not found.
Type material. Female holotype and 3 female paratypes (Reg. No. AMU–SYR.583) from the Yellow-crested Cockatoo Cacatua sulphurea (Gmelin) (Psittaciformes: Cacatuidae) [host no. ZSM 11.2488], INDONESIA: West Timor, Lesser Sunda Islands, East Nusa Tenggara Province, Kupang Regency, Fatulaeu District, Camplong I (Tjamplong), 28 July 1911, coll. Haniel.
Type material deposition. All type specimens—AMU, except 1 female paratype —ZSM.
Differential diagnosis. Lawrencipicobia sulphurea sp. nov. is morphologically similar to above described L. calyptorhyncha sp. nov. by the presence of one pair of pseudanal setae ps1. The new species differs from L. calyptorhyncha by the following features: in females of L. sulphurea, setae ve are 57–63 µm long; setae g1 are represented by microsetae and 6–9 µm long, and the agenital plates are narrow. In females of L. calyptorhynycha, setae ve are 91–105 µm long; genital setae g1 are setiform and about 20 µm long; and the agenital plates are absent.
Etymology. The name sulphurea is taken from the specific name of the host, and is a noun in apposition.
