2. Montchadskiana glareolae Dabert and Ehrnsberger,
1999 ḆẄP요ẍṵḍűΞή (ṳÿ) ( Figs. 3 View Fig , 4 View Fig )
Synonyms. Montchadskiana glareolae Dabert and Ehrnsberger, 1999, p. 228 -233, figs. 10, 14.
Material examined. Korea: 3♂♂, 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 GoogleMaps .
Diagnosis. Male: Length 550-560 of idiosoma from anterior end to ends of terminal membranes, width 210-230 at level of humeral shields, length to width ratio 2.4-2.5 ( Fig. 3A View Fig ). Prodorsal shield ( Fig. 3B View Fig ): Triangle-shaped, covers the entire pronotum, posterior part with transversal striation, length 145-150 along midline, width 155- 160, with two internal vertical seta (vi). Hysteronotal shield ( Fig. 3C View Fig ): Anterior part concave, with transversal striation excluding lobar part, length 355-365 from anterior margin to base of setae h3, width 175-185 at level of setae c2. Opisthosomal lobes rounded lateroposterior ends with narrow terminal membranes. Setae ps2 and h3 leaf-like ( Fig. 3E View Fig ). Sternum ( Fig. 3B, D View Fig ): Epimerites I fused. Genital apparatus long and massive, located between trochanters IV. Genital papillae situated on anteri- or to genital apparatus between bases of legs IV. One to two pair of small irregular genital sclerites located laterally to the base of genital apparatus. Adanal shield shaped inverted as V, fused with medial irregular sclerite, with medial sclerite two times longer than its width.
Female: Length 550-570 of idiosoma from anterior end to bases of setae h3, width 200-230 at level of setae c2, length to width ratio 2.4-2.7 ( Fig. 4A View Fig ). Prodorsal shield ( Fig. 4B View Fig ): Shaped as in male. Length 155-165 at based of setae vi, width 160-170 at posterior part. Hysteronotal shield ( Fig. 4C View Fig ): Anterior part concave, with transversal striation excluding the area between setae d2 and Opisthosoma part, length 395-405, width 190-210 at based of setae c2. Setae h1 divided into two branches at the base, the longest branch twice as longer than the shorter branch. Terminus rounded with shallow medial incision. Sternum ( Fig. 4D View Fig ): Epigynum absent. Supranal concavity circular-shaped and separated from terminal terminus. Small ventroterminal shield located behind the posterior opisthosoma.
Remarks. Montchadskiana glareolae was separated from M. ulitae Dubinin, 1951 by Dabert and Ehrnsberger (1999) and was described based on specimens collected from T. glareola in Poland. Montchadskiana glareolae is very similar to M. ulitae with regard to external traits. However, M. glareolae can be clearly distinguished from M. ulitae by the following characteristics: (1) genitoanal region has small irregular genital sclerites in male; (2) length of adanal shield is two times longer than the width of this shield; and (3) setae h1 are divided into two branches at the base in the female ( Dabert and Ehrnsberger, 1999). Korean specimens were morphologically consistent with the original description and illustrations ( Dabert and Ehrnsberger, 1999). However, the idiosoma width of Korean males were slightly wider than the original description. We consider this to be intraspecific variation.
Host. Specimens were collected from the surface of flight feathers on the wings of wood sandpiper Tringa glareola .
Distribution. India, Poland, Russia, Thailand ( Dabert and Ehrnsberger, 1999), Korea (this study).
Deposition. NIBR No. NIBRIV0000812906, NIBRIV00 00820670-820674.
Molecular characteristics. The COI sequences were obtained from two individuals and deposited in GenBank with accession numbers of MK031704 and MK031705.
