The species of freshwater Cyclopoida Cyclops bohater Kozminski 1933 was recorded during collection of zooplankton in one of the three Čingi-Lingi Lakes in August and September 2004. This is the first record for the Croatian fauna and also for the Balkan Peninsula. The Čingi-Lingi Lake is a gravel pit in the Podravina area of NW Croatia.Prilikom uzorkovanja zooplanktona u jednom od tri jezera Čingi-Lingi u kolovozu i rujnu 2004. godine zabilježena je vrsta slatkovodnih Cyclopoida Cyclops bohater Kozminski 1933.

It is supplied by waterfrom underground flow of the Drava River, which is located 750 m from the lake.Geographic coordinates of the sampling point are N46°08'11'' and E17°03'11''.Sampling and determinationSpecimens were collected on 1 August 2004, 16 August 2004 and 2 September2004 at a depth of 16 m by means of vertical hauls using plankton net with a meshsize of 67 mm. Samples were preserved in 4% formaldehyde. For the purpose ofdetermination and measurement, four adult females were dissected in glycerol andanalysed under an Olympus microscope. Determination was carried out accordingto EINSLE (1993), EINSLE (1996) and KIEFER (1978). All terms for body structure areused from HUYS & BOXSHALL (1991).RESULTSCyclops bohater Kozminski 1933Determination characteristics of C. bohater compared with Einsle (1996)(Tab. 1).Female. Body length is 2,2 to 2,5 mm. The antennule is with 17 segments (Fig. 2),reaching end of second pedigerous somite, this latter strikingly wide with largelateral lobi. Ends of fourth and fifth pedigerous somites are wide and pointedoutward, but no »wings« are present (Fig. 3). The caudal rami have a length:widthproportion 6,2 – 6,8:1, divergent, the inner margin with hair-setae (Fig. 4). Theterminal accessory seta is longer than the caudal rami (1,3 – 1,4:1), long comparedwith body length (~16%). The inner terminal seta is twice the length of the terminalaccessory seta, 1,8 – 1,9:1, in proportion to the caudal ramus and 30 – 31% of bodysize. The outer terminal seta is twice the length of the caudal rami and about 27%of body length. The posterolateral seta is half the length of the terminal accessoryseta and 0,6:1 in proportion to the caudal ramus.Spine formula is 3433 (Fig. 5 – 8). First segment of the antenna has severalgroups of spines, variable (Fig. 9). Seta on the basis of swimming leg 1 is reachingend of the second endopodal segment. Intercoxal sclerite of swimming leg 4 iswithout setae, humps surpass margin (Fig. 10). Coxa of swimming leg 4 has allgroups of spines (A to F) (Fig. 11). Distal segment of swimming leg 5 is slender,inner lateral spine inserting at middle, shorter than segment (Fig. 12).NAIDENOV & PANDOURSKI (1992) made an incorrect determination of Cyclopsbohater ponorensis n. ssp. so PANDOURSKI (1997) renamed it as C. a. divergens.
