Three new species of parasitic mites of the genus Neharpyrhynchus Fain (Acariformes, Harpirhynchidae) are described from Neotropical birds: Neharpyrhynchus chlorospingus sp. n. from Chlorospingus pileatus (Passeriformes, Emberizidae) from Costa Rica, Neharpyrhynchus mironovi sp. n. from Dacnys cayana (Passeriformes, Thraupidae) and Neharpyrhynchus tangara sp. n. from Tangara cayana (Thraupidae) both from Brazil. Neharpyrhynchus trochilinus (Fain) is recorded from 3 new host species of the family Trochilidae (Apodiformes), Panterpe insignis and Eugenes fulgens from Costa Rica, and Amazilia lactea from Brazil. Emended diagnosis of the genus and a key to species are provided; all records of Neharpyrhynchus species are summarized.

Mites of the genus Neharpyrhynchus Fain (Acariformes, Harpirhynchidae) are permanent and highly specialized parasites of birds, as is the case for all other representatives of the subfamily Harpirhynchinae (
Most species of the genus are known from European passerines and only two species are known from Neotropical birds, Neharpyrhynchus baile Bochkov et al. from Turdus leucomelas (Passeriformes, Turdidae) (

Birds were examined by naked eye for the presence of
harpirhynchids and released back to the wild. S.V. Mironov and I.
Literak examined birds in the field. Mites were cleared in lactophenol
and mounted in Hoyer’s medium. Specimens were studied using a Leica
microscope under Nomarsky interference-contrast-phase (DIC) optics.
Drawings were made with a camera lucida, and measurements were taken
using a calibrated ocular micrometer. Drawings were made by A. V.
Bochkov. In the species description, names of the leg and idiosomal

Neharpyrhynchus mironovi sp. n., female holotype, A dorsal view B ventral view.
The species is named in honour of the prominent Russian acarologist Dr. Sergey V. Mironov (ZISP).
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 fromNeharpyrhynchus 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.

This species was briefly diagnosed from both sexes collected from an unidentified species of hummingbird (Trochilidae)
that originated from South America (exact locality unknown) and died in
the Zoo of Antwerp (Belgium) during its quarantine. Later on,
The longitudinally subdivided dorsal shield of this species is an artifact sometimes induced by the mite mounting. In this species, actually, the dorsal shield is entire. It differs from the closely related Neharpyrhynchus baile Bochkov et al. by the following characters. In females of Neharpyrhynchus trochilinus, setae dF, dG, and l”G are subequal, legs III and IV with 5–6 setae each, setae si and se 25–35 long. In Neharpyrhynchus baile, setae dF is about 1.5 times longer than dG and l”G, legs III and IV as a rule with 4 setae each, setae si and se are 6–12 long.
