COMPARISONS: This species is readily distinguished by its ratio of tail length to head-and-body length (fig. 9; table 2) from all Crocidura species on Sulawesi except other members of the Long-Tailed Group. Within the Long-Tailed Group, C. caudipilosa is smaller and has a much hairier tail, shorter hind foot, paler pelage, and lower relative interorbital width (IOW / CIL) but greater relative braincase breadth (BB / CIL) (figs. 9, 10). Within the Elongata Subgroup, C. microelongata has a smaller body size, shorter tail, shorter and slightly darker hind feet, and shorter skull than C. elongata and C. quasielongata (fig. 12; table 5). The thenar pad on the hind foot is shorter than in C. elongata, but comparable to that of C. quasielongta (fig. 14). Although the skull is shorter, its breadth is similar to that of the other two species, whether measured at the braincase, interorbital area, or rostral region (figs. 10, 12). The interorbital region, however, is more tapered than in either of the two most similar species (fig. 18). The dentition of C. microelongata is slightly smaller in proportion to the skull than in either C. elongata or C. quasielongata (fig. 18).
