03CC6D01F372FFFAFF77FA080028F9B7.taxon	materials_examined	Holotype and paratypes. In permanent slides, deposited in the collection of the National Institute of Biological Resources, Incheon, Korea (holotype: KOSPIV 0000192577; two paratypes: KOSPIV 0000192578, and KOSPIV 0000192579). Specimens isolated from mosses growing on a tree trunk at Wanggok-ri, collected by Min Ok Song. Type material is further fixed with 4 % formalin after boiling water fixation (Pennak 1978), and preserved in 100 % glycerin (Stemberger 1979). Type locality. Wanggok-ri, Goseong-gun, Gangwon-do, Korea. GPS 38 ° 22 ’ 48.46 ” N / 128 ° 28 ’ 2.78 ” E Material. Five specimens found in mosses growing on a tree trunk at Wanggok-ri, Goseong-gun, Gangwondo. Differential diagnosis. In the genus Bradyscela, only two species, B. clauda (Bryce, 1893) and B. granulosa De Koning, 1947, have previously been described. B. hoonsooi n. sp. seems to be more morphologically similar to B. clauda than to B. granulosa. B. clauda and B. hoonsooi n. sp. have numerous papillae surrounding the posterior margin of the second foot pseudosegment, whereas B. granulosa has two very small spurs, which are usually hidden inside the U-shaped swollen part of the second foot pseudosegment. B. hoonsooi n. sp. can be distinguished from B. clauda by the following morphological characteristics: (1) the number of teeth on the outer margin of the rake apparatus; and (2) the number and shape of papillae around the posterior margin of the second foot pseudosegment. B. hoonsooi n. sp. has four teeth on the outer margin of the rake apparatus, whereas B. clauda has six; B. hoonsooi n. sp. has approximately 42 thin papillae, two thin and knobby papillae, and two thick paddleshaped papillae, whereas B. clauda has approximately 21 short and round-ended papillae and two inverted triangleshaped papillae; and the majority of papillae in B. hoonsooi n. sp. are thinner and much longer than those of B. clauda.	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.

03CC6D01F374FFF8FF77F8E906A3FD05.taxon	materials_examined	Material. Eight specimens found in mosses and leaf litter on a mountain in Jeongan-myun, Gongju-si, Chungcheongnam-do. This species is easily diagnosed by its spurs, which are bow-shaped, long, stiff and with a wide interspace. It is very rare and has recently been rediscovered in Arizona, USA by Birky (reported on-line at http: // www. eebweb. arizona. edu / faculty / birky / BirkyLab. html) after description from Sonora, Mexico by Örstan (1995). The two previous reports were from desert areas, whereas the Korean specimens were found in mosses and leaf litter on a mountain. Our present record suggests that M. sonorensis is not limited to the desert. The general morphology of the Korean specimens conforms to that of the type specimens, except that the lower head part after the rostrum does not have a swollen appearance during creeping. The median lobes of upper lips were either smooth or with three small processes positioned asymmetrically in the original specimens. The shape of the entire upper lip, especially in dorsal view, was not mentioned in the original description. The upper lips of the Korean specimens are triangular with a truncated median lobe. The median lobe is slightly concave and has a very low median projection (Fig. 3 d); this can make the upper lip appear to have three small processes. The original description did not mention the morphologies of the sulcus and disc retractor. In the Korean specimens, the disc retractor is convex and the sulcus has two small triangular processes medially (Fig. 3 d).	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.

03CC6D01F376FFF8FF77FA160773F85B.taxon	materials_examined	Material. Two specimens found in mushrooms growing on tree trunks at Gosu-ri, Danyang-gun, Chungcheongbuk-do, September 22, 2013. This species is relatively rare and has previously been reported only from Brazil (Murray 1913), since its original description from tropical Africa by Murray (1911). The characteristics of the Korean specimens agree well with those of the type specimens. H. acornis is distinguishable from its congeners by the following characteristics: (1) the upper lip is arched with a thick and wavy margin, much lower than the sulcus, and with each side extended like an auricle; (2) the pseudosegment around the trophi is much wider than both the previous and the following pseudosegments, and has a trapezoidal outline, which is maintained during feeding; and (3) the sulcus has a large conical projection medially. According to the original description, it was never observed in a nest or tube, although many characteristics indicated that the species was a tube-dweller (Murray 1911). In the present study, we did not observe any of the Korean specimens in nests or tubes.	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.

03CC6D01F376FFF8FF77FC950013FB49.taxon	materials_examined	Material. One specimen found in mosses from Gosu-ri, Danyang-gun, Chungcheongbuk-do, September 22, 2013. Milne (1916) described this species from the Republic of South Africa (Milne 1916). This species was subsequently reported from Namibia (Koste 1996 a), Madagascar (Koste 1996 b), and New Zealand (Haigh 1965). In the present study, we discovered it in Korea. This species is easily distinguishable by the morphologies of the corona and spurs. The corona is much wider than the collar width, and twice as wide as the width of a pseudosegment carrying an antenna. The spurs are conical with round ends, approximately half as long as the width of the spur pseudosegment, and with the interspace slightly narrower than the spur base width.	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.

03CC6D01F378FFF6FF77FF430773FD66.taxon	materials_examined	Material. Two specimens found in mosses and soil from Hansan-do, Tongyeong-si, Gyeongsangnam-do, August 15, 2013. Since the original description from the Netherlands by De Koning (1947), the distribution of this species has been restricted to several countries in Europe (Donner 1965) and New Zealand (Shiel & Green 1996). This species is easily recognized by its long feeding head, on which the space between the upper lip and the rostrum is quite extended. It also has a very long neck, which makes the pharyngeal tube three times as long as the trophi length. Another important diagnostic characteristic of this species is the triangular projection in the middle of the sulcus (Fig. 5 a). Donner (1965) did not mention this projection in sulcus, however, it was depicted in one of the figures (Abb. 15 c) of Donner (1949). The general morphology of the Korean specimens conforms the original description, except for the following characteristics: (1) the trunks of the Korean specimens are not granulated; and (2) the first foot pseudosegments of the Austrian population (Donner 1949) are much longer than those of the Korean specimens. The feet of the Korean specimens are short and barely stretched fully (Fig. 5 d).	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.

03CC6D01F378FFF6FF77FCCA00C4FA37.taxon	materials_examined	Material. Two specimens found in mosses and soil from Hansan-do, Tongyeong-si, Gyeongsangnam-do, August 15, 2013. The present study is the first to record this species since the original description from the Netherlands by De Koning (1947). The characteristics of the Korean specimens coincide well with those of the type specimens. The original description of this species seems to have been mainly based on feeding specimens in nests; therefore, it does not provide details regarding the morphology of the trunk in either feeding or creeping posture. In the Korean specimens, the trunk is constricted all around, immediately before the preanal pseudosegment; this makes the rump rather round. During feeding, the part of the trunk before the rump tends to become plump (Fig. 6 a). None of the Korean specimens were observed in nests. This species closely resembles H. longula Bryce, 1915; however, the two species can be distinguished by the following characteristics: (1) in H. fuscochlaena, each trochal disc has a rather round anterolateral margin in dorsal view, whereas in H. longula, each trochal disc has a squarish anterolateral margin in dorsal view; (2) the sulcus of this species is very narrow and U-shaped, whereas that of H. longula is V-shaped and rather shallow; and (3) The rim of the upper lip of H. longula is much thicker and wavier than that of this species.	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.

03CC6D01F378FFF6FF77FA390773F83D.taxon	materials_examined	Material. Two specimens found in mushrooms growing on tree trunks at Gosu-ri, Danyang-gun, Chungcheongbuk-do, September 22, 2013. This species has previously been reported from five European countries since the original description from the United Kingdom and Austria by Bryce (1915) (Donner 1965). The present study is the first one to record the species outside Europe. The characteristics and body sizes of the Korean specimens agree closely with those of the type specimens, except that the corona is as wide as the cingulum pad. This species can be easily diagnosed by its long dorsal antenna, thick and wavy rim of the upper lip, and trochal discs with squarish anterolateral margins.	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.

03CC6D01F37CFFF2FF77FF4304CBFBA2.taxon	materials_examined	Material. Two specimens found in mosses and leaf litter on a mountain in Mongsanpo, Seosan-si, Chungcheongnam-do, April 14, 2013. The distribution of this species has previously been limited to seven European countries, including its type locality, Austria, since the original description by Donner (1954). The present study is the first one to record the species outside Europe. This species closely resembles H. solitaria Donner, 1949 and H. eremita (Bryce, 1894). Donner (1962) placed these three species in a “ solitaria - visa - eremita ” group, and examined the variations in body size, trophi length, feeding head length, dental formula, corona width, collar width, sulcus width, upper lip morphology, presence or absence of a projection on the sulcus, and egg size (Donner 1962). The most distinguishable characteristic may be the ratio of the corona width to the collar width, which is 0.75 – 0.93 for H. solitaria, 0.92 – 1.11 for H. visa, and about 1.38 for H. eremita (Donner, 1962). There is a little overlap between H. solitaria and H. visa in the range of the ratio. The second most useful diagnostic characteristic is the width of the sulcus, which is very narrow in H. solitaria and very wide in H. eremita (Donner 1962). In the Korean specimens, the ratio of the corona width to the collar width is 1.09, and the sulcus widths lie between those of H. solitaria and H. eremita. The morphology of the feeding heads of the Korean specimens is most similar to that of the Austrian population, which was previously attributed to H. eremita by Donner (1949), and subsequently recognized as belonging to H. visa by Donner (1954) (Donner 1949; 1950; 1954; 1962). The general morphology of the Korean specimens conforms to those of the European populations, except that the body color is reddish. The Korean specimens have a triangular projection in the middle of the sulcus, but they don’t have any median process on the upper lip.	en	Song, Min Ok, Min, Gi-Sik (2015): A new species and ten new records of bdelloid rotifers from Korea.
