Cryptocandona brehmi (Klie, 1934) (Figs 5 A–D, 6). 1934 Candona brehmi n. sp. —Klie: 197, figs 11–14. nov. comb. 1947 Cryptocandona brehmi (Klie, 1934) —Bronshtein: 263. Material examined. Eighteen females from a large pond fed by a spring approximately 325 meters upstream, at the foot of Mount Ibuki, Ueno, Maibara, Shiga Prefecture N 35 º 23 ’ 31.0”, E 136 º 23 ’ 33.7 ”, altitude 346 m, 2 August 2010. Material collected by the author. Size: length 831–892 µm, height 379–419 µm. Remarks. Previously this species has been recorded only once, from a cave in Nagano Prefecture (Klie 1934; Namiotko and Danielopol 2002). This species is very similar to Cryptocandona reducta (Alm, 1914), and is distinguished from it mainly by shorter lengths of the G 3 and GM claws of the antennae, a relatively short Sp seta on the caudal ramus, only very weakly protruding genital lobe and smaller size of the carapace. (For more details see Namiotko and Danielopol 2002). In their redescription of the only known syntype, Namiotko and Danielopol (2002) noted that the antennules are asymmetrical. However, the antennules of specimens collected in Shiga Prefecture are symmetrical, suggesting that the asymmetrical antennules of the syntype are an anomaly. The antennules of the Shiga specimens are most similar to the left one of the syntype, (Fig. 6 B) suggesting that the right antennule of the syntype is the anomalous one. This species was found in a pond in a wooded area, on a substrate of fallen leaves on sand. The pond is fed by a large, fast flowing spring about 325 meters upstream of a steep, wooded valley. The spring extrudes from a boundary of limestone above a clay layer. : Published as part of Smith, Robin J., 2011, Groundwater, spring and interstitial Ostracoda (Crustacea) from Shiga Prefecture, Japan, including descriptions of three new species and one new genus, pp. 15-37 in Zootaxa 3140 on pages 22-23, DOI: 10.5281/zenodo.207945 : {"references": ["Klie, W.
