Type deposition. Holotype and most paratypes in UMMZ, 1 female paratype in ZISP.

Etymology. The specific epithet is derived from the host family name and is a noun in the genitive case.

Hosts and distribution. Birds of the family Picidae (Piciformes) from North America ( USA): Colaptes auratus [type host], Melanerpes formicivorus, M. uropygialis , and Picoides pubescens (present paper).

Differential diagnosis. Among species of the group baile , Neharpyrhynchus picidarum sp. nov. is close to N. baile Bochkov et al., 2007 , N. bochkovi Martinu et al., 2008 , and N. trochilinus Fain, 1972 . In females of these species, palpal setae vF are serrate and the anterior part of the propodonotum is unornamented. The new species differs from these three species by the following character states. In females of N. picidarum , palpal setae dF are about 1.2 times longer than dG (vs. 1.4–1.5 times longer in N. baile and N. bochkovi ; subequal in N. trochilinus ). In addition, it differs from N. trochilinus by the following features. In females of N. picidarum , setae si and c2 are 8– 11 long (vs. 25–35 long in N. trochilinus ), legs IV usually are with four setae, rarely are with five setae (vs. usually with five setae, rarely with six setae in N. trochilinus ), the body is subequal or longer than 600 (vs. shorter than 500 in N. trochilinus ). In males of N. picidarum , the genital opening is situated anterior to the level of setal bases c2 (vs. posterior to this level in N. trochilinus ).
