Description. FEMALE ( Figs 13–21 ). Total body length of holotype 755 (715–740 in three paratypes). Gnathosoma . Infracapitulum densely punctated. Each transverse branch of peritremes with 5 chambers, each longitudinal branch with 15 chambers ( Fig. 16 ). Stylet of movable digit long, about 145. Stylophore not punctated, 180 (180) long. Idiosoma . Propodonotal shield well sclerotized, punctated at lateral margins, rectangular in shape, bearing bases of setae vi, ve, si, se, and c1. Setae se and c1 situated at same transverse level. Length ratio of setae vi: ve: si 1:1.1–1.3:1.6–1.7. Hysteronotal shield well sclerotized, fused to pygidial shield, sparsely punctated near bases of setae d1. Setae d1 situated about twice closer to d2 than to e. Setae f1 and h1 short and subequal in length. Setae h2 3.5 times longer than setae f1. All dorsal setae, except terminal setae (f1, f2, h1 and h2) knobbed ( Fig. 18 ). Genital setae g1 and g2 subequal in length. Genital plate weakly sclerotized ( Fig. 17 ). Pseudanal setae ps1 and ps2 subequal in length. Cuticular striations as in Figs 13 and 14 . Legs. Coxal fields of legs I–IV well sclerotized and densely punctated. Solenidia of legs I as in Figure 19 . Apodemes of legs I parallel, not fused to apodemes II. Setae tc” of legs III and IV twice longer than tc’III–IV.

Propodonotal shield well sclerotized, sparsely punctated at lateral margins, rectangular in shape, bearing bases of setae vi, ve, si, se, and c1. Setae se situated slightly anterior to level of setae c1. Hysteronotal shield well sclerotized, fused to pygidial shield. Setae d1 situated about twice closer to d2 than to e. Setae h 10–11 times longer than setae f. Ano-genital region as in Figure 24 . Aggenital setae ag3 slightly (1.3 times) longer than ag1. Cuticular striations as in Figs 27 and 28 . Legs. Apodemes of legs I divergent, not fused to apodemes II. Claws strongly curved ( Fig. 25 ). Setae tc” of legs III and IV twice longer than tc’III–IV. Fan-like setae p’ and p” of legs III and IV with 4–5 tines each ( Fig. 26 ).

Type material. Female holotype, 3 female and 2 male paratypes ( BMOC 83–0608–6) ex. covert quill of Phalaropus fulicarius (Linnaeus) ( Charadriiformes : Scolopacidae ), USA: San Diego Co., San Diego, 2–6 December 1982, coll. J.R. Jehl.

Type deposition. All material is deposited at UMMZ .

Etymology. The name phalaropi derives from the generic name of the host.
