<p class="Body"><strong>Two new feather mites (Acari: Analgoidea) isolated from the grey-headed woodpecker, <em>Picus canus</em> (Piciformes: Picidae) in Korea</strong></p>

Abstract

Two new species of feather mites from the superfamily Analgoidea are described from the grey-headed woodpecker, Picus canus, in Korea: Neopteronyssus koreanus sp. nov. (Pteronyssidae) and Proterothrix picinus sp. nov. (Proctophyllodidae: Pterodectinae). Feather mites of the genera Neopteronyssus Mironov, 2002 and Proterothrix Gaud, 1968 are described for the first time in Korea. Morphological descriptions of both new species are complemented with partial sequences of their mitochondrial cytochrome c oxidase subunit I (COI) gene as DNA barcodes.

New Record of Feather Mite, Neopteronyssus bilineatus Mironov, 2003 (Arachnida: Pteronyssidae), from a Grey-Capped Pygmy Woodpecker, Yungipicus canicapillus in Republic of Korea

“…In contrast, in males of N. yungipicinus , the posterior part of hysteronotal shield lacks ornamentation, and the length of seta r III is 2.5 times shorter than the length of this tarsus; and in females, 2 elongated hysteronotal plates are situated between setae d2 and e2 [ 25 , 32 ]. In addition, hysteronotal shield in males of N. koreanus is weakly sclerotized without 2 longitudinal sclerites, and tarsal seta r III is 1.5 times shorter than tarsus III; in females, pair of anterior hysteronotal plates are located at the level of setae d1 and usually shaped as irregular rectangles (in few specimens, these plates fused by thin sclerite) [ 23 ].…”

“…The genus Neopteronyssus Mironov, 2003 is one of about 23 genera belonging to the family Pteronyssidae Oudemans, 1941 that comprises 17 species, generally associated with woodpeckers of the family Picidae Leach, 1820 [ 23 , 25 ]. The genus Neopteronyssus is classified into 3 species groups, i.e., pici , picinus , and pycnospilus [ 25 ].…”

“…The genus Neopteronyssus is classified into 3 species groups, i.e., pici , picinus , and pycnospilus [ 25 ]. The differences of these 3 groups are the transventral sclerite of epiandrium and dorsobasal teeth of tarsus IV in males and the shape of hysteronotal shield in females [ 23 , 25 , 26 ]. In the pici group, 5 species, i.e., N. bilineatus Mironov, 2003; N. elongatus (Buchholz, 1869); N. koreanus Han et al 2019; N. pici (Scopoli, 1763); N. yungipicinus (Mironov, 1987), have been reported in worldwide [ 23 , 25 ].…”

“…To date, 9 species of woodpecker in the family Picidae are known to inhabit Korea [ 27 , 28 ]. Among these woodpeckers, the grey-headed woodpecker, Picus canus , was reported as the host of N. koreanus in Korea [ 23 ]. Therefore, in the present study, we intended to record a species of feather mite, Neopteronyssus bilineatus (Arachnida: Pteronyssidae), from a grey-capped pygmy woodpecker, Yungipicus canicapillus (Blyth, 1845), in Korea.…”

“…The cleared mite samples were mounted on microscope slides in PVA mounting medium (BioQuip, Rancho Dominguez, California, USA) and identified with a Leica DM2500 microscope (Wetzlar, Germany) equipped with DIC (differential interference contrast) optics and microscopic digital camera. Description of the species was given according to the recent format used for species of genus Neopteronyssus [ 23 , 25 , 26 ]. Morphological terminology and nomenclature of leg and idiosomal setae followed Gaud & Atyeo [ 29 ] and Norton [ 30 ].…”
