(Figures 7–10)
Description. Female (Figures 7–10). Body weakly sclerotized. Length of idiosoma 120 (115–125), width 75 (70– 80). Gnathosoma (Figure 7). Gnathosomal capsule, excluding palps, almost round, its length 26 (26–28), width 26 (26–31). Dorsally with two pairs of blunt-ended cheliceral setae (cha, chb). Setae cha 15 (15–16) barbed, distinctly longer than smooth chb 6 (6). Dorsal median apodeme well developed. Postpalpal setae (pp) rod-like, situated posterolaterally to setae cha. Venter of gnathosoma with one pair of smooth, pointed subcapitular setae m 10 (10– 11). Palps freely articulated to gnathosomal capsule, with smooth setae dFe and dGe dorsolaterally, setae dGe pointed, more than three times longer than blunt-ended dFe. Palps ventrally with two subequal solenidia. Palps terminated with well-developed tibial claw. Cheliceral stylets strong, curved. Pharynx thin-walled, with divided into four weak lateral projections situated close to each other inside gnathosomal capsule.
Idiosomal dorsum (Figures 7 A, 10A, C). All dorsal shields with sparsely distributed dimples (Figures 7 A, 10C). Prodorsal shield with three pairs of setae (v 1, v 2, sc 2); setae sc 1 completely absent (Figure 10 C). Setae sc 2 pointed; other dorsal setae blunt-ended. Setae v 2, e, h 1 and h 2 smooth, other dorsal setae weakly barbed. Cupules ia on tergite D, im on tergite EF and ih on tergite H small, round. Posterior margin of tergite D with several very weak projections. Lengths of dorsal setae: v 1 17 (17–18), v 2 3 (3), sc 2 44 (41–44), c 1 20 (20–21), c 2 20 (19–20), d 16 (16– 17), e 8 (8–9), f 18 (18–19), h 1 7 (7–8), h 2 60 (59–61). Distances between setae: v 1 –v 1 25 (24–25), v 2 –v 2 34 (34–35), sc 2 –sc 2 37 (36–37), c 1– c 1 24 (22–24), d–d 53 (53–54), e–e 43 (43–44), f–f 33 (32–33), h 1– h 1 11 (11–12), h 1– h 2 7 (7).
Idiosomal venter (Figures 7 B, 10B, D). All ventral plates with sparsely distributed dimples. All ventral setae smooth, needle-like. Ap1 and ap2 well developed and joined with appr, apsej well developed only in lateral parts; ap3 and ap4 well developed. Poststernal apodeme absent. Coxal fields I and II each with two pairs of setae (1 c and 2 c absent) (Figure 10 D). Coxal fields III and IV each with three pairs of setae. Lengths of ventral setae: 1 a 7 (7–8), 1 b 6 (6), 2 a 11 (11–12), 2 b 4 (4–5), 3 a 9 (8–9), 3 b 8 (8–9), 3 c 8 (8–9), 4 a 9 (8–9), 4 b 8 (8–9), 4 c 8 (8–9), ag 5 (5– 7), g 1 2 (2–3), g 2 3 (3), ps 3 (3).
Legs (Figures 8, 9). All legs subequal in length. Leg I (Figure 8 A). Setal formula: 0–4–1–6(2) –11(2). Tarsus with two small claws and semioval empodium. Setae (u) and (pv) with widened and flattened tips. Setae d of femur weakly barbed; other leg setae smooth. Setae l’ of femur, l’ of genu, k, v’, l” of tibia blunt-ended; other leg setae (except eupathidia) pointed. Trochanter dorsolaterally with short projection. Tarsus I with ventrodistal membranous flange. Lengths of solenidia ω 1 6 (6)> ω 2 4 (4–5) <φ 1 6 (6)> φ 2 4 (4); Solenidion φ 2 baculiform, other solenidia clavate. Leg II (Figure 8 B). Setal formula: 0–2–1–4(1)–6(1). Tarsal claws simple, hooked; empodium large. Solenidion ω 4 (4–5), clavate, solenidion φ 4 (4) baculiform. Trochanter dorsolaterally with short projection. Setae tc”, u’ and (pv) slightly widened and flattened distally. Setae l’ of tibia and tc’ of tarsus slightly thickened. Seta v” of femur blunt-ended; other setae pointed. Setae v” of femur, d, l’ of tibia, tc’ and pl” of tarsus weakly barbed; other leg setae smooth. Leg III (Figure 9 A). Setal formula: 0–1–1–4–5. Claws and empodium of same shape as on tarsus II. Setae d of femur, l” of genu and all tarsal setae blunt-ended; other leg setae pointed. Setae l’ and v” of tibia weakly barbed; other leg setae smooth. Leg IV (Figure 9 B). Setal formula: 0–1–1–4–5. Claws and empodium of same shape as on tarsus III. Setae d of femur and all tarsal setae blunt-ended; other leg setae pointed. Seta v” of tibia weakly barbed; other leg setae smooth.
Male unknown.
Type material. Female holotype, slide No. 10721, Brazil, Mato Grosso, Cuiabá municipality, October 2016, A. Frolov leg., on Canthon histrio. The mites were attached to the membrane connecting pro- and mesothorax of the beetles; paratypes: 11 females, same data.
Type deposition. The holotype and three paratypes are deposited in the collection of UNESP—Universidade Estadual Paulista, Department of Zoology and Botany, 15054–000 São José do Rio Preto –SP, Brazil; five paratypes are deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia; two paratypes are deposited in the collection of the Zoological Institute of RAS, Saint Petersburg, Russia.
Differential diagnosis. The new species considerably differs from all known species of the genus by the absence of setae 1 c and 2 c on coxal fields I and II (vs. present in other species). The female of the new species is most similar to P. sabzevarensis Hajiqanbar and Khaustov, 2010, described from Iran (Hajiqanbar & Khaustov 2010), by the absence of setae sc 1 and the same leg setation. In addition to the absence of setae 1 c and 2 c, the new species differs from P. sabzevarensis by its blunt-ended dorsal idiosomal setae c 1 and d (vs. pointed in P. sabzevarensis).
Etymology. The name of the new species referring to its distribution in Neotropical region.
