Allozyme electrophoresis was used to determine the systematic affinities of nine forms of carrion-breeding blowfly of the genus Calliphora: C. stygia, C. albifrontalis, C. augur, C. dubia, C. hilli hilli, C. hilli fallax, C. varifrons, C. sp. nov., and C. maritima. The results (1) confirm the species status of all forms currently described as such, (2) support a return to the ranking of C. hilli fallax as a full species, C. fallax, (3) support the recognition of C. sp. nov. as a distinct species, and (4) indicate that distinct Kangaroo Island and adjacent mainland subpopulations appear to exist in at least three species. The allozyme data also strongly support the placing of eight of the forms into three separate species-groups on morphological grounds, and the placement of C. maritima in a fourth group. However, on the basis of these data, the comparative genetic affinities of the parasitic blowfly Onesia tibialis suggest that Calliphora in its current form may be paraphyletic.

Background Pattern

An ornamental freshwater shrimp, Neocaridina davidi, is popular as an aquarium hobby and, therefore, a potentially invasive species. There is a growing need for proper management of this species to determine not only their optimum breeding conditions, but also their ability to colonise novel environments. We tested habitat preferences of colour morphs (brown, red, white) of N. davidi for substratum colour (black, white, grey shades, red) and fine or coarse chess-board patterns to recognise their suitable captivity conditions and predict their distribution after potential release into nature. We conducted laboratory choice experiments (n = 8) with three individuals of the same morph exposed for two hours to a range of backgrounds. Shrimp preferred dark backgrounds over light ones irrespective of their own colouration and its match with the background colour. Moreover, the brown and red morphs, in contrast to the white morph, preferred the coarse background pattern over the finer pattern. This suggests that the presence of dark, uniform substrata (e.g., rocks, macrophytes) will favour N. davidi. Nevertheless, the polymorphism of the species has little effect on its total niche breadth, and thus its invasive potential.

The main morphological traits of Galumna lawrencei Jacot, 1940 stat. nov. and Galumna natalensis Jacot, 1940 stat. nov. (Oribatida, Galumnidae) are presented based on the type material from South Africa. We consider that these species are not subspecies of Galumna maxima as was proposed originally by Jacot 1940, but independent species. A lectotype for G. lawrencei is designated, due to the mixed-species cotype series.
