Synonymy. Sida crystallina ortiva Korovchinsky, 1979 , p. 1785–1786, Fig. 2 View FIGURE 2 : 1–2, 7, 9, 12; Korovchinsky 2004, p. 253, Fig. 79: 4, 6, Fig. 80: 2, 5; Kotov et al. 2011b, p. 404.
Type locality. “The Amur River near mouth of the Sungari River”, Jewish Autonomous Area, Russia ( Korovchinsky 1979). Coordinates: approximately 47.7ºN, 132.5ºE.
Localities in Korea. 1, 10, 11 (see Fig. 1 and Table 1 View TABLE 1 ).
Parthenogenetic female. Body ovoid, head small, with a large anterior and a pair of smaller anchor organs ( Fig. 2 View FIGURE 2 A, arrows) dorsally, dorsal margin convex, postero-dorsal angle expressed, posterion margin straight, postero-ventral margin expressed, bearing a spine. Rostrum relatively short, directed ventrally, compound eye large, situated near ventral head margin, ocellus very small ( Fig. 2 View FIGURE 2 B). Posterior valve margin with a row of numerous marginal spinules ( Fig. 2 View FIGURE 2 C). Postabdomen trapezium-shaped, comparatively short; ventral margin straight, preanal margin long, straight, anus opens distally ( Fig. 2 View FIGURE 2 D–E). Row of 12–14 anal teeth along each lateral side, rows of minute spinules near these teeth. Postabdominal claw regularly bent, with four basal spines, proximal most spine only somewhat smaller than next spine ( Fig. 2 View FIGURE 2 E). Postabdominal setae long, about 0.4 of body length, located on a strong projection. Antenna I long, with distal aesthetascs and distal sensory seta longer than the former ( Fig. 2 View FIGURE 2 F). Antenna II long, basal segment long, with some spines distally ( Fig. 2 View FIGURE 2 G). Antennal formula in our material: setae 0 −4-7/ 0−1−4. Six pairs of thoracic limbs, not different from those in S. crystallina described by Korovchinsky (2004). Size in our material 1.5–2.4 mm.
Notes. Sida crystallina ortiva Korovchinsky, 1979 was established at the subspecies rank. But preliminary molecular phylogenetic studies suggest deep divergence with S. crystallina ( O.F. Müller, 1776) (Kotov & Taylor, unpublished). Sida crystallina is widely distributed in the Western Palaeractic and penetrates Eastern Palaearctic up to Far East; S. ortiva is present in Siberia, Far East of Russia and more southern areas of eastern and south-east Asia ( Korovchinsky 2004; Kotov et al. 2011b). Both species are found in South Korea. S. crystallina was found by us in localities 3 and 12, see Fig. 3 View FIGURE 3 A–G, and was illustrated by Kim & Yoon 1987, Fig. 2 View FIGURE 2 a–e and Yoon 2010, Fig. 18 View FIGURE 18 B. It differs from S. ortiva mainly in (1) longer rostrum projected posteriorly; (2) proximal most basal spine on postabdominal claw significantly shorter than the next spine and located close to it.
