The seven subfamilies shown are those of Hellmayr J. Smith (1970). of the (1926). Euscar- Adapted see (1966). The genera Todirostrum and Idioptilon contain 26 of these species (14 and 12 respectively), and each of the re- maining 6 species is currently placed in a monotypie genus. Together, the 32 species clearly represent a well-circumscribed, monophyletic group, though their affinities have received little critical attention, and none at all since Zimmer's brief comments on some of them (1940, 1953, 1955). As an initial stage in the investigation of the evolution and modern competitive structure of the group, the distributions of all Euscarthminc species were carefully plotted on maps. These distributions were examined in relation to recent theories in.
