Stibarokris phoeniconaias sp. nov.

( Figs 74–77 )

Description. FEMALE ( Figs 73–77 ). Total body length of holotype 820 (785–845 in five paratypes). Gnathosoma . Infracapitulum punctated. Each transverse branch of peritremes with 6–7 chambers, each longitudinal branch with 15–17 chambers ( Fig. 76 ). Stylet of movable digit 170 (170) long. Stylophore constricted posteriorly and punctated, 215 (200–215) long. Idiosoma . Propodonotal shield well sclerotized, punctated at lateral margins, bearing bases of setae vi, ve, si, se, and c1. Setae se and c1 situated at same transverse level. Setae vi, ve, and si subequal in length. Hysteronotal shield not fused to pygidial shield, punctated in anterior part, bearing bases of setae d1 and e. Setae d2 situated about 3 times closer to d2 than to e. Pygidial shield well sclerotized, sparsely punctated in posterior part or without punctations. Dorsal setae of idiosoma vi, ve, si, se, c1, d1, d2, and e knobbed ( Fig. 77 ), setae c2 slightly ornamented or smooth, setae f1, f2, h1, and h2 smooth. Setae h1 1.7–2 times longer than f1. Setae h2 about twice longer than f2. Aggenital setae ag3 slightly (1.2–1.3 times) longer than ag1 and ag2. Pseudanal setae subequal in length. Genital setae g1 1.4–1.8 times longer than g2. Cuticular striations as in Figs 73 and 74 . Legs. Apodemes I divergent, not fused to apodemes II. Coxal fields of legs I–IV well sclerotized and punctated. Setae tc”III–IV about twice longer than tc’III–IV. Fan-like setae p’ and p” of legs III and IV with 6–8 tines each. Setae 3c 1.3–1.5 times longer than 3b. Podomeres of legs sparsely punctated. Setae sc3 reach tarsus. Length of setae: vi 70 (70–80), ve 70 (70–80), si 80 (80–90), se 145 (170–195), c1 170 (170–175), c2 185 (180–195), d1 130 (115–125), d2 120 (125–135), e 145 (155–195), f1 30 (20–30), f2 295 (320–370), h1 50 (45–55), h2 640 (635–645), ps1 and ps2 20 (20), g1 55 (60), g2 40 (45–50), ag1 285 (245–260), ag2 250 (245–270), ag3 330 (330–340), tc’III–IV (35–45), tc”III–IV (90–100), 3b (120–125), 3c (175–190), sc3 105 (105).

MALE. Not found.

Type material. Female holotype and 6 female paratypes ( BMOC #82–1212–1) ex. quill of secondary coverts of Phoeniconaias minor (Geoffroy Saint-Hilaire) ( Phoenicopteriformes : Phoenicopteridae ); BOTSWANA: bird died in captivity and received in November 1982, coll. B.M. OConnor .

Type deposition. All type material is deposited at UMMZ .

Etymology. The name phoeniconaias refers to the generic name of the host.

Differential diagnosis. S. phoeniconaias sp. nov. is similar to S. langei Bochkov et Mironov, 1999 described from Ciconia ciconia (Linnaeus) ( Ciconiiformes : Ciconiidae ) from Russia ( Bochkov & Mironov 1999). In females of both species, the movable cheliceral digits are dentate, the hysteronotal shield is not fused to the pygidial shield, setae vi, ve, and si are subequal in length, all dorsal setae except the terminal setae are knobbed, and setae h1 are longer than f1. This new species differs from S. langei , by the following characters: in females of S. phoeniconaias sp. nov., each longitudinal branch of the peritremes has 15–17 chambers, the lengths of aggenital setae ag1 and ag2 are 245–285 and 245–270, respectively, and the fan-like setae p’ and p” of legs III–IV are with 6–8 tines. In females of S. langei , each longitudinal branch of the peritremes has 11–12 chambers, the lengths of aggenital setae ag1 and ag2 are 103–135 and 135–157, respectively, and the fan-like setae p’ and p” of legs III–IV are with 11–12 tines.
