KOZÁR* s collection, but subsequently it was deposited (together with a second instar larva on the same slide) in the collection of the Zoological Department of the Hungarian Natural History Museum, Budapest. Further paratypes (9 females on 7 slides) and two slides with 5 first and one second instar larvae with the same data, were deposited in the Research Institute for Plant Protection, Budapest. Description of adult female: The live female is pinkish in coloration. The mounted female 2.0-3.5 mm long and 1.0-1.5 mm wide, oval. Eyes situated at body margin. Antennae long, slender; 8-segmented, joint VIII is the longest. Mounthpart strong, robust, labium 2-segmented, stylet loop shorter than labium. Legs are long, robust. Posterior coxae with 10-40 pores. Tarsal and apical digitules longer than claw, apex with a small knob. Spiracles of typical structure, without a distinct group of 3-locular pores. Circulus large, oval, divided. Anal lobes poorly developed. Anal ring oval, with two rows of pores, inner row with big, oval pores, while outer one with small, rounded pores. No 5-locular pores. Multilocular pores of small number sitting on the last abdominal sternites, forming 3-4 rows and a band. There are no multilocular pores on other parts of the body. The 3-locular pores are numerous on the ventral and dorsal surfaces of body. The long, slender oral collar ducts being numerous on the last abdominal sternites and only some of them are scattered on venter of thorax. The oral rim ducts in a sparse row on the tergites and some of them are near the median and posterior coxae. The maximum number of oral rim ducts on tergite VIII is 5. Dorsal ostioles well developed, with 3-locular pores and setae. Only last cerarii (Cjg) developed, they are on a sclerotized plate, with two big conical setae, with 3-4 hair-like setae and with 20-30 3-locular pores. Hair-like setae thin and short on venter and on dorsum. The most distinctive character of the only European species of the genus ( C. rostrellum ) are given in the table: rostrellum from C. viktorina sp.n.
