到目前为止存在的Cyclops vicinus kikuchii Smirnov，1932年，最初由来自日本的材料描述；后来在俄罗斯、波兰和捷克斯洛伐克发现。与Cclopps vicinus Uljanin，1875相比，该亚种的主要特征是内柄较短(1号)，与柄和体长成比例。根据Wierzbicka(1934)的说法，这两种类型都可以杂交产生可生育的后代。在梅尔斯堡(康斯坦茨湖)附近的“Neuweiher”老水库收集的材料，以及进一步在Seeg湖和“Schwaltenweiher”(巴伐利亚南部)收集的材料，允许进行形态和形态计量学研究(图3)。1、Tab.I)，通过比较染色质减少和酶电泳法完成。形态研究(表2)。I)证实了内柄刚毛的长度与华南虎的长度存在差异。仅有的五个来自塞格湖的标本至少表明了季节性变化的可能性。染色质减少的过程(图2)。2)在质量方面，两种环翅目昆虫看起来是相同的。在酶电泳法中，谷草转氨酶(GOT)、精氨酸磷酸激酶(APK)和磷酸葡萄糖变位酶(PGM)差异显著(P<0.05)。3)。结合形态特征和在塞格湖和“Schwaltenweiher”的同地分布，这些结果证实了种Cyclops kikuchii Smirnov，1932年的独立地位。本种在夏季的5龄桡足类幼虫中度过滞育，而在4龄幼虫中滞育。
The hitherto existing subspecies Cyclops vicinus kikuchii Smirnov, 1932 was originally described by materials from Japan; later it was found in Russia, Poland, and Czechoslovakia. Compared with Cyclops vicinus Uljanin, 1875 the subspecies is characterized mainly by the short inner furcal seta (no. 1) in proportion to furcal and body length. According to Wierzbicka (1934) both types could interbreed to produce fertile offspring. Materials collected in an old reservoir, the "Neuweiher" near Meersburg (Lake Constance), and further in Lake Seeg and in the "Schwaltenweiher" (southern Bavaria), allowed morphological and morphometrical studies (fig. 1, tab. I), completed by comparative chromatin diminution and enzyme electrophoresis. The morphological studies (tab. I) confirmed the differences in length of the inner furcal seta compared with C. vicinus. The only five specimens from Lake Seeg at least indicate the probability of a seasonal variation. The course of chromatin diminution (fig. 2) appears identical in qualitative aspects for both cyclopids. In the enzyme electrophoresis remarkable differences were found in GOT (glutamate oxaloacetate transferase), APK (arginine phosphokinase) and PGM (phosphoglucomutase) (fig. 3). Together with the morphological details and the sympatric occurrence with C. vicinus in Lake Seeg and in the "Schwaltenweiher", these results confirm the separate status of the species Cyclops kikuchii Smirnov, 1932. This species passes its diapause during summer in the fifth copepodid instar, while C. vicinus aestivates in the fourth instar.
