Material examined. Korea: 2♂♂, 3$$, Gyeolseongmyeon, Hongseong-gun , Chungcheongnam-do, 36°31 ʹ 36 ʺ N, 126°33 ʹ 41 ʺ E, May 11, 2016, collected using vacuum machine from flight feathers on the wings of wood sandpiper Tringa glareola by Han Y.-D .

Diagnosis. Male: Length 475 of idiosoma from anterior end to bases of setae h3, width 215-225 at level of humeral shields ( Fig. 1A ). Prodorsal shield ( Fig. 1B, 1D ): Triangular shaped, posterior margin with medial projection, posterior angles extending laterally the bases of setae se, length 115-125 along midline, width 115-120 at posterior part. Hysteronotal shield ( Fig. 1B ): Anterior part straight, lateral parts with small rounded extensions at level of setae cp, length 325-335 from anterior margin to bases of setae h3, width 130-135 at level of setae d1. Interlobar cleft transverse ovoid, with anterior margin concave. Interlobar membrane expanded at the distal ends of the lobes. Incision in interlobar membrane elongated ovalshaped, anterior margin round-shaped lateral margins with shallow incisions in midlength. Postlobar membranes with one rectangular and two acute teeth. Sternum ( Fig. 1C ): Epimerites I not fused, with distal edges curved outwards. Genital apparatus located between levels of trochanters III and IV. Genital papillae situated on anterior to base of genital apparatus. Adanal shields absent.

Female: Idiosoma length 430-450, width 215-225 ( Fig. 2A ). Prodorsal shield ( Fig. 2B ): Mostly shaped as in male, length along middle line 120, width 125 at posterior part. Hysteronotal shield ( Fig. 2B ): Shaped as in male, posterior part with stronger sclerotization, length 310-320, width 145-155. Opisthosoma terminus rounded. Terminal cleft semicircular. Sternum ( Fig. 2C ): epimerites I shaped as in male. Epigynum arch-shaped, length 38-43, width 63-68.

Remarks. Avenzoaria totani was originally described by Canestrini (1878) based on specimens collected from Tringa totanus (= Totanus totanus ). Thereafter, this species was reported by several mite taxonomists from birds of families Anatidae and Scolopacidae ( Mégnin and Trouessart, 1884; Dubinin, 1951; 1956; Gaud and Mouchet, 1959; Gaud, 1972; Vasjukova and Mironov, 1991; Dabert, 1992; 2000; Badek and Dabert, 2005).

Avenzoaria totani is distinguishable from other species in the genus Avenzoaria by several characteristics in males: (1) posterior angles of prodorsal shield are extend- ed laterally at the base of setae se; (2) postlobar membranes are comprised of one rectangular and two acute teeth; and (3) genital papillae are situated on anterior to base of genital apparatus (Vasjukova and Mironov, 1991; Badek and Dabert, 2003). The Korean specimens were morphologically consistent with the descriptions and illustrations provided by Vasjukova and Mironov (1991) and had partial CO1 sequences (565 bp) identical with those of Avenzoaria totani (GenBank no. GQ864348.1) registered in GenBank.

Host. This species was found on wings feathers in the wood sandpiper Tringa glareola .

Distribution. Cameroon, Congo ( Gaud and Mouchet, 1959; Gaud, 1972), Italy ( Canestrini, 1878; Dubinin,

1956), Russia ( Dubinin, 1951; 1956; Vasjukova and Mironov, 1991), Poland ( Dabert, 2000; Badek and Dabert, 2006), Korea (this study).

Deposition. NIBR No. NIBRIV0000812908, NIBRIV00 00820666-0000820669.

Molecular characteristics. The COI sequences were obtained from two individuals and deposited in GenBank with accession numbers of MK031702 and MK031703.
