Description.

Female (holotype).

Idiosoma, including gnathosoma, 675 long (660-680 in 10 paratypes), 425 wide (420-435) (Fig. 4). Gnathosoma 135 long (130-140), 150 wide (140-155). Palps 65-75 long, distinctly inflated dorsally. All palpalae distinctly pectinate (Fig. 5A). Lengths of palpalae: dF 40 (38-40), dG 30 (28-33), and l"G 30 (30-35); dF only slightly longer than dG and l"G. Setae vF about 100 long, smooth. Subcapitulum ventrally with setae n and m, about 80 long. Peritremal branch about 120 long. Idiosoma 525 long (510-530). Anterior region of propodonotum covered by short rounded scales situated irregularly in its posterior half (Fig. 6B). Dorsal shield entire, 200 long in midline (190-200), 350 at maximum width (350-370) (Fig. 4A). Anterior margin of dorsal shield almost straight, with pair of lateral anteriorly directed projections; posterior margin with distinct median concavity. This shield covered by fine rhomboid-like pattern, almost indistinct in anterior half and more clearly discernible in posterior half. Ventral surface of idiosoma with indistinct transverse striations, without scales or verrucosities (Fig. 4B). Setal lengths: vi, ve, and si - all distinctly barbed, subequal in length, 160-175; se and 1a 12-25, c2 50-60- all smooth; h1 whip-like, 250 (250-280); 1b smooth, 30-40, 3a absent. Base of legs I with distinctly developed fleshy lobe partially covering leg segments; base of legs II with moderately developed rounded lobe. Leg I with 2 articulated segments (Fig. 5B). Leg II with 2 articulated segments (Fig. 5C). Legs III, IV with one segment, each bearing 4 long setae. One ventral seta of leg III and 2 ventral seta of leg IV about 150 long, about half the length of other setae situated dorsally or dorsoterminally, 250-300 long.

Male.

Unknown.

Etymology.

The species is named in honour of the prominent Russian acarologist Dr. Sergey V. Mironov (ZISP).

Differential diagnosis.

It is close to species of the group “pilirostris”. In all these species, setae vF are smooth, only two articulated segments on legs I and II are present, and setae 3a are absent. Among species of this group, Neharpyrhynchus mironovi is close to Neharpyrhynchus pari by the presence of four setae on leg III and by irregular ornamentation of the anterior part of the propodosoma. The new species differs from Neharpyrhynchus pari by the following characters. In females of Neharpyrhynchus mironovi , the palps are distinctly inflated dorsally, the ornamentation of the anterior part of the propodonotum is scale-like and present only in the posterior half of this region, setae c2 are 50-60 long. In Neharpyrhynchus pari , the palps are moderately inflated dorsally, the anterior part of the propodonotum is fully ornamented by verrucosities and setae c2 are 5-6 long.
