. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. 84 R. H. L. Disney. Fig. 7: Clitelloxenia assmuthi the two developing oocytes in a single female. The upper oocyte (of the left side) has ceased growing, the lower egg (of the right side) is nearing maturity. (Scale bar = mm). development of one egg halted, but in the other egg there is increasing differentiation of the contents, with the formation of an increasingly distinct chorion. The most mature eggs exhibit very little variation in length. Smaller flies do not have smaller mature eggs than larger flies, they have more immature eggs (which are therefore smaller) than are to be found in larger flies. In a few large flies no developing eggs could be observed. In these cases the appearance of the abdomen suggested that the lack of an egg was probably due to it having been recently laid. Measurements of developing eggs found are presented in Table 2. The data in Table 2 provide no support for the hypotheses based on assuming that the females in the four regions have different growth characteristics. The most parsimonious conclusion, therefore, is that hypothesis (1) an accident of sampling, is sufficient to explain the differences between the samples from the four regions. Until defensible differences can be demonstrated, therefore, it is proposed to treat the material from the four regions as belonging to a single species, which continues to lengthen its femora and head right up to the oviposition of its first mature egg at least. Thus C. peradeniyae, C. longiceps and C. hemicyclia are herewith proposed as further synonyms of C.
