(Figures 9–66, 75–85)
Larva (Figures 9–17)
Body length: 380 mm, body width: 190 mm; colour: white
Rostrum with rostral incision. Surface of prodorsum with small pits. Setae ro delicately barbed, bent, slightly shorter than half the distance between their bases. Setae le frayed, on small apophyses; setae in setiform; both setae almost as long as ro. Sensilli third as long as in. One pair of alveolae ex visible.
Surface of notogastral plate covered with small pits and folds. With 12 frayed and phylliform notogastral setae, except setae h 1, which are equal in width, with uneven margins. Setae c 1, c 3, d 1, d 3, e and h 2 half the length f 1; d 2 third as long as f 1. Setae c 2 quarter as long as c 1, placed closer to c 1 than to c 3. Setae f 2 shorter than f 1 but longer than e 2. Setae h 1 almost three times longer than f 1, with branched caves inside. Oval opening of opisthosomal gland (gla) situated below seta f 2.
Pairs of epimeres medially separated. Epimeral setation: 2-1-2. Genital, aggenital and adanal plates, and anal setae lacking.
All legs monodactylous (setation not studied).
Protonymph (Figures 18–29)
Body length: 470 mm, body width: 230 mm; colour: white, light brown
Setae ro as long as half of the distance between their bases. Setae in longer and broader than ro, notched. Sensilli 1.5 times longer than distance between their bases, slightly barbed and apically pointed. Setiform setae ex three times shorter than ro.
Surface of notogastral plate covered with small pits. With 16 frayed notogastral setae, except setae h 1. Setae c 1, c 3, d, e, f 1 and h 3 half shorter than f 2. Setae c 2 shorter than c 3, placed closer to c 1 than to c 3. Setae h 1 as long as f 2, with branched pits, set on apophyses. Setae h 2 as long as their mutual distance, apically narrowed, with branched pits. Setae p 1 as long as distance p 1 – h 2, with branched caves inside, on apophyses. Setae p 2 longer than h 3; p 3 similar to ro. Oval opening of opisthosomal gland (gla) situated near seta f 2.
Pairs of epimeres separated. Epimeral setation: 2-3-3-(2,3). Genital plates with one pair of short setae. Aggenital, anal and adanal setae lacking.
All legs monodactylous (setation not studied).
Deutonymph (Figures 30–43)
Body length: 630 mm, body width: 310 mm; colour: light brown
Surface of prodorsum with small pits. Setae ro almost twice longer than distance between their bases. Setae le similar to in.
Setae p 2 as long as h 3. Other notogastral setae similar to protonymphal setae. Oval opening of opisthosomal gland (gla) situated below seta f 2.
Epimeral setation: 4-4-4-2 (hardly visible). Genital plates with four pairs of short setae; three pairs of adanal setae. Aggenital and anal setae lacking.
All legs monodactylous (setation not studied).
Tritonymph (Figures 44–53, 75 – 78)
Body length: 670 mm, body width: 320 mm; colour: light brown
Setae ro half shorter than distance between their bases. Setae le as long as ro. Setae in twice longer and broader than le. Setiform setae ex half shorter than ro.
With 16 frayed and narrower than deutonymphal notogastral setae. Setae c 2 as long as le, placed closer to c 1 than to c 3. Setae h 3 similar to h 1. Setae p 1 longer than distance p 1 – h 2. Setae p 2 shorter than c 2; p 3 half shorter than p 2. Other notogastral setae similar to deutonymphal setae. Oval opening of opisthosomal gland (gla) situated below seta f 2.
Epimeral setation: (6-7)-4-3-4. Genital plates with seven pairs of setae; two pairs of anal setae; three pairs of adanal setae.
All legs monodactylous (setation not studied).
Adult (Figures 54–66, 79 – 85)

Setae ro pointed distally, almost as long as their mutual distance. Setae le and in similar to ro in length. Sensilli longer than distance between their bases, completely barbed, distally pointed. Setae ex short, setiform.
Surface of notogastral plate covered with pits of different sizes. Shape of notogastral setae similar to tritonymphal setae. Setae c 2 and c 3 equally long, shorter than c 1; c 2 placed closer to c 1 than to c 3. Setae h 1 almost twice longer than c 3. Setae h 2 almost as long as their mutual distance. Setae h 3 similar to h 1. Setae p 1 as long as distance p 1 – h 2.
