“…Previous studies of the karyotypes in this family (Metz, 1916;Boyes, 1953Boyes, , 1963Kaul et al, 1978) have shown that the size of the sex chromosomes varies considerably among species, as also occurs for other dipteran groups (Boyes and Boyes, 1975;Kaul and Tewari, 1979; Parise, P.P.M., unpublished data). The results of our analysis of the karyotype of P. intermutans fit this pattern of autosomal and sex chromosomic organization.…”

“…Their data indicate that the 12-chromosome complements of Muscidae are somewhat longer (73.6 tx for 413 complements); of Sarcophagidae, very similar in length (65.9 tx for 220 complements; and of Tachinidae somewhat shorter (57.4 ~ for 187 complements). In the Acalyptratae, 42 complements of Otitidae have 2n = 12 and averaged 51.5 tx (BOYES et al, 1973b), 624 of Sciomyzidae, 66.5 Ix and 71 of Lauxaniidae 58.1/x (BOYES et al, 1975). In the Brachycera 11 such complements averaged 50.8 tx in the Stratiomyiidae ; 10 averaged 39.9 tx in the Tabanidae (BOYES & WILKES, 1972) and 8 in the Bombyliidae averaged 41.7 fx (BO'CES & SHEWELL, 1973C).…”

A modification of the general system of classification of Calliphoridae is proposed in this report. Information about the chromosome complements of about 90 species is provided including references to the earlier literature on chromosomes of this family. With one exception all species studied by us or by earlier investigators have 2n = 12. The total complement length of 556 complements from 83 species averaged 66.4/x. Most species have a short heteromorphic sex pair but the size and morphology vary considerably and one species, HemipyreUia fernandica, seems to have a quadrivalent sex-chromosome complex in a 2n = 14 complement. The autosomal pairs vary in both length and arm ratios between the species but seem to be more stable than the sex chromosomes. Only minor variations were found between different collections of the same species except for two collections of Calliphora croceipalpis. Although presently available data on the chromosomes of Diptera species suggest that increases in total complement length accompany evolutionary progress, no such general trends were obvious in either the total complement lengths or chromosome morphology, either within or between the tribes of Calliphoridae. Thus the karyotypical reorganizations in the family have apparently not been directly associated with changes in the general morphological features of the adults which may have responded in these respects more extensively to genetic mutations.

The diploid chromosome complement of S. nubiZa is 2n = 14 including sex chromosomes of the XY type. This karyotype is very similar to that of Pericoma modesta but the sex chromosomes in S. nubila are smaller. Like in P. modesta they behave as univalents and regularly pass undivided to opposite poles at first meiotic anaphase. Otherwise spermatogenesis is normal. A supernumerary chromosome was found in one specimen among thirty examined.
