Material examined here. 6 parthenogenetic females from Lukie lake, Poleski Park Narodowy, Lublin Area, Poland, 02.07.2011, coll A.Y. Sinev & I. Zawiska; over 50 parthenogenetic females, 10 ephippial females, 5 males from Nizhnee Ershovskoe lake, White Sea Biological Station of Moscow State University, Republic of Karelia, Russia, 08-09.1996, coll. E. I. Izvekova, A. Y. Sinev; 20 parthenogenetic females, ephippial female, 7 males from Nero lake, Yaroslavl Area, Russia, 15.IX.1987, from N. N. Smirnov’s collection; over 30 parthenogenetic females from pond #1 on Gnilichka river, Nizhnii Novgorod, Russia, 29.07.2018, coll. V. S. Zhikharev; 17 parthenogenetic females, 2 males from pond near 9 th Dachnaja street, Saratov, Russia, 09-10.1998, coll. E. E. Morozova; over 30 parthenogenetic females lake at Arylakh village, Yakutia Autonomous Republic, Russia, N 62.44764° N, 130.9635° E, 30.8.2010, coll. A.A.Kotov, AAK 2011-057; over 100 parthenogenetic and ephippial females, over 50 males from pond in Avangard village, Nakhodka District, Primorsky Area, Russia, 13.X.1999, leg. E.N. Temereva.
Material examined earlier. See list of material in Sinev (2001). Morphology of studied specimens (see Fig. 9) agrees with the earlier descriptions of the species (Frey 1988; Alonso 1996; Sinev, 2001; Van Damme & Dumont 2008a; Hudec, 2010). Additional seta near scraper 1 of limb II (Fig. 9C) was found in all studied populations, and lateral aestetascs on male antennule (Fig. 9E) was found in all studied populations with males present.
Area of distribution. Palaearctic and Oriental regions. Records of C. (C.) rectangula in Subsahel Africa, Arabia and Central Asia should be rechecked due to presence of sibling species, C. (C.) cf. bukobensis and C. (C.) anemae (see Van Damme & Dumont 2008), and also C. (C.) hardingi. Records from Australia need also to be rechecked. Recorded from New Zealand and Australia C. (C.) novae-zelandiae is very similar to C (C.) rectangula in outer morphology, but description of its limbs (Smirnov 1971) leaves no doubts that it is a separate species, clearly different from C. (C.) rectangula in morphology of IDL setae.
