Setae S5 short (18-28). Dorsal plate with 43 pairs of setae, setae r2– r6 and R series on the plate. Dorsal setae short (15 –22) with the exception of j1, r3 and Z5. Unsclerotised venter in female with 13 pairs of long setae (27–42) and one pair of postcoxal setae. Male with ventral spine on femur IV. Spermatodactyl relatively short (113–115).
Female (Holotype). Dorsum. Body length 602 (608–684 in five paratypes), width 407 (395–489). Dorsal plate covering whole dorsum, with slight transverse structure, 467 (458–476) long, 332 (320–332) wide. Dorsal plate with 43 pairs of short setae, series r2–r6 and R on the plate. Setae j1 41 (39–44) long, strong, but setiform, setae Z5 extremely long and strong, measuring 94 (80–95). Setae z5 only slightly longer (18–22) than setae j5 (15–17) and setae r3 slightly longer (28-40) than r2 (18–22). A row of fine denticles situated at the anterior margin of the plate. Peritreme reaching the level of z1. Small lyriform pores present posterior to z1.
Ve n te r. Sternal plate 135 (132–159) long (presternum included), 376 (357–407) wide, finely structured in its lateral part, with posterior cornua small and blunt. Sternal setae 40–41 (37–44), Mst longer 51 (49–54). Two pairs of lyriform pores near St1 and posterior to St2. Genital plate slightly broadened posterior to coxa IV, with scale-like structure. Genital setae measuring 42 (40–47). Anal plate pyriform, 110 (105–122) long, 87 (82–90) wide, with a pair of adanal setae 25 (24–30), a post-anal seta 69 (65–69) and a pair of circular pores on its lateral border. Unsclerotised venter with 14 pairs of long setiform setae. Ventral setae measuring: Jv1 42 (39–42), Jv2 54 (49–54), Jv5 87 (84–88), Zv1 32 (27–32). Endopodal platelets present, metapodal platelets narrow (33– 40 x 3–5), posterior to coxa IV.
Gnathosoma. Deutosternum with 7 rows of denticles, 5th and 6th rows widened and curved, row 5 concave, rows 6 and 7 convex. Epistome rounded and strongly toothed. Fixed chela with three fine subapical teeth, movable chela with three lateral teeth and membranous lobe. Inner seta on palpfemur and palpgenu flattened at the tip. Corniculi pointed and curved to inside.
Legs. Tibia III with 8 setae, tibia IV with 10 setae. All leg setae setiform and smooth.
Male. Dorsum. Body length 495 (476–482 in three paratypes), width 338 (323–332). Dorsal plate with fine transverse pattern, 467 (458–476) long and 332 (320) wide, with 43 pairs of short fine setae. Seta j1 and r3 longer than remaining dorsal setae, measuring 39 (28–35) and 34 (32–34) respectively, setae Z5 83 (76–81) long. Remaining dorsal setae short, measuring 14–20, except, z1 and j5 very short (10–12). A pair of lyriform pores situated near z1 setae. Peritreme ending at level of z1.
Ve n te r. Genitoventral plate 189 (184–189) long (including genital pore), 220 (206–213) wide, with fine scale-like structure. Genitoventral setae 29–34 long, except Gv4 which are 42 (39–42) long. Two pairs of lyriform pores are present near Gv1 and between Gv2 and Gv3. Ventri-anal plate broadly triangular, narrowed in anal part, transversely structured, 189 (184–189) long, 220 (206–213) wide. There are 6 pairs of ventral setae, a pair of adanal setae 20 (20–24) and a long post-anal seta 56 (49–52). Setae Zv1 short 20 (17–20), Jv1 30 (30–32) long, Jv2 44 (37–39). Setae Jv5 extremely long 59 (50–56), situated similarly as Jv4 and Zv4 on small sclerotized platelets. Peritremal plate narrow.
Gnathosoma: Deutosternum as in female, spermatodactyl relatively short, measuring 115 (113–115) only. Fixed chela with two teeth, movable chela with one tooth.
Legs: Legs II slightly thickened with some posteroventral setae slightly thickened. Strong ventral spine on femur IV present. All setae on legs IV setiform and smooth. Tibia III with 8 setae, tibia IV with 10 setae.
Notes. The new species differs from other species of the P. belemensis group in body and shield measurements and in the length of male spermatodactyl. The presence of 13 pairs of ventral setae on unsclerotised integument in the female, and the presence of setae Jv5, Jv4 and Zv4 on small sclerotized platelets in the male also help to distinguish the new species from other known species of the P. belemensis group.
The males and females of P. threnetes Dusbabek & Literak, sp.nov. and P. naskreckii Dusbabek & Havlicek, sp. nov. were associated according to the following criteria. In both cases males and females were collected together from the same host individual. No other males were recorded in association with females of these two species. In both cases the main recognition characters of females occurred also in males: Setae j1 and r3 with lateral bulbous swelling or relative long dorsal setae of j, J, z,and Z series, namely the relation of S5 and Z 5 in P. threnetes, and setae j1 and r3 without lateral bulbous swelling, dorsal setae of j, J, z, and Z series short, including seta S5 which are clearly shorter than the half of Z5. We have collected two more males (two distinct species) which have no common characters with P. chalybura Dusbabek & Capek, sp. nov. Because two only specimens were collected, we were not able to associate them to any known Proctolaelaps species.
Etymology. The species is dedicated to Dr. Piotr Naskrecki, Conservation International and Harvard University, USA, a specialist in hummingbird flower mites of the family Ascidae.
