THE MACARIINI: A PERSPECTIVE Details of macariine structure, both for adults and immature stages, are provided by Krüger (2001) in a work on African species. The introductory component to that study applies across the tribe so just a perspective on macariine biology is presented here. Macariines typically are medium-sized, ennomine geometrids with a global distribution. Many species live in tropical or subtropical regions, although only 15 described species are listed for Australia (McQuillan & Edwards, 1996). The group is well represented in North America with 253 species recorded by Hodges et al . (1983). A total of 270 macariine species (previously described or new) are accepted by Krüger (2001) in Africa, Madagascar and Arabia. Macariines also occur in cold regions, as far north, for example, as northern Yukon, Canada (McGuffin, 1972) and the Kola Peninsula, north-western Russia (Kozlov & Jalava, 1994). The tribes probably most closely related to Macariini are Cassymini and Eutoeini (Holloway, [1994]; Krüger, 2001). In all three groups, the pupa has a bifid cremaster and in males the valva is divided. The Boarmiini, which are also related, have a bifid cremaster but the valva is usually undivided (Holloway, [1994]). Wing pattern varies across the tribe as, to a lesser extent, does wing shape. Nevertheless, one arrangement is of particularly widespread occurrence across genera and geographical regions. Examples are shown in Figs 22,33,188. The purpose of the whole moth figures (colour and black and white) is to illustrate variation across the tribe, so proportionally few moths with this pattern have been illustrated in the present work compared with the number that exists. This phenotype is found, particularly, in Macaria , Chiasmia , Semiothisa and Oxymacaria , making it difficult to assign species with this appearance to the appropriate genus based on external appearance alone. There are two components to this wing form – wing shape and wing pattern. The forewing is angular rather than rounded and ...
