“…They generally have obscure polytene chromosomes, which may be why so few species have been studied cytologically (8). Only Liriomyza urophorina has been in vestigated (46,47); it showed chromosomal polymorphism for six paracentric inversions.…”

“…Thus, sex determination must be of the XY and not of the XO-type. MAINX (1951) andMAINX et al (1956) did not find any chromosomal differences between males and females of Liriomyza urophorina. From the population data, the authors have come to the conclusion that there is a chromosome with the genetical function of a Y chromosome.…”

The polytene chromosomes from the gastric coeca of Cerodonta (Butomomyza) eucaricis Nowakowski are described. There are five long and one dot‐like chromosome, the latter with indistinct bands. The X chromosome is number 5 and shows an allocyclical behaviour: In male larvae the bands are less distinct and the whole chromosome is much shorter than in female larvae. A material of 1444 larvae has been cytologically investigated. From their chromosomal morphology they could be classified as belonging to two different semispecies or perhaps sibling species. 1061 larvae belonged to the first semispecies and 349 to the other. The two semispecies occur as a rule sympatrically and may hybridize in nature. The hybrids are fertile, at least to some extent. The semispecies differ in one fixed inversion in the X chromosome and in five floating autosomal inversions. The two semispecies do not share any polymorphisms, but by occasional hybridization inversions could be transferred from one of the two semispecies to the other. Possible mechanisms for reproductive isolation and taxonomic state are discussed.

“…In the family Agromyzidae all members are leaf or stem miners and thus, at least at their larval stage, they show a dependence on a certain plant species, genus or family. MAINX (1951) and MAINX, FIALA and KOGERER (1956) hava studied chromosomal variation in Liriomyzu urophorina MIK. This species, which is restricted to Lilium martugon, also displayed chromosomal polymorphism.…”

Amauromyza (Trilobomyza) flavifrons (Meigen) has a chromosome number of 2n = 6. In mitotic metaphase there are two metacentric and one subtelocentric pair. In polytene chromosomes there are 5 chromosome arms. Chromosome maps are presented. In 762 individuals from 11 localities polymorphism was found for 7 structural rearrangements: two simple paracentric inversions, two double inversions of the included type, one shift in close contact with a simple inversion, one asymmetric band and one asymmetric puff. No intermediate forms of the complex rearrangements were found. The rearrangements were distributed over 4 of the 5 chromosome arms. Within each locality all rearrangements were observed in equal frequencies on different occasions. Between localities, however, variation in frequencies occurred. 8 of the 11 localities contained equal frequencies of all rearrangements, but the remaining 3 localities showed deviations from the other 8 and they also differed from each other. No correlation between frequency of different rearrangements and ecology could be observed. Therefore, chromosomal polymorphism could be regarded as rigid rather than flexible but not in a typical form.
