HOLOTYPE: MZB 43011 (= FMNH 218726 About FMNH ), an adult male, collected on 5 May 2012 by J.A. Esselstyn. The specimen comprises a skull ( fig. 41B View FIG ), formalin-fixed body, and frozen tissues. External measurements from the holotype are 142 mm × 65 mm × 16 mm × 10 mm = 11.0 g. The voucher specimen and a tissue sample will be permanently curated at MZB and an additional tissue sample will be retained at FMNH.

TYPE LOCALITY: Indonesia, Sulawesi Barat, Mamasa, Mamasa, Tondok Bakaru , Rantepangko , Mt. Gandang Dewata ; 2.8181° S, 119.3823° E, 2200 m elevation.

ETYMOLOGY: Ordinaria is Latin for “ordinary,” used in recognition that this is yet another species of shrew with no striking or unique phenotypic traits worthy of a descriptive name.

GEOGRAPHIC DISTRIBUTION: Crocidura ordinaria is found in the west-central area of endemism (Mt. Gandang Dewata, West Sulawesi Province and Mt. Torompupu, Central Sulawesi Province) ( fig. 39 View FIG ). The species spans an unusually broad elevational range from approximately 200 to 2600 m ( fig. 13 View FIG ; table 3 View TABLE 3 ).

DIAGNOSIS: A moderately sized shrew ( tables 2 View TABLE 2 , 14 View TABLE 14 ) with a somewhat stocky build. The pelage is medium to dark gray-brown and thick, with hairs at the middorsum typically 6–7 mm long. The venter is paler, with hairs that are pale gray at the tip, but dark gray at the base. In some specimens, the tips of some ventral hairs are reddish brown, giving the belly and chest pale cinnamon highlights. The mystacial vibrissae are short and darkly pigmented for at least half their lengths. Dorsally, the feet are nearly as dark as the pelage, but some specimens have much paler digits ( fig. 40B View FIG ). The tail is shorter than head and body ( fig. 9 View FIG ) and the abundance of tail bristles and applied hairs is variable. The skull of this species is typical in its length (relative to body size) for a Sulawesi shrew but is wide at the braincase and interorbital region relative to skull length ( fig. 10 View FIG ; table 14 View TABLE 14 ). The braincase, though broad, is not especially inflated vertically. The dentition is more prominent than expected given the palatal width ( fig. 41B View FIG ), but, otherwise, the skull of Crocidura ordinaria is unremarkable.

COMPARISONS: Crocidura ordinaria is a moderately sized member of the Ordinary Group. The tail is shorter than head-and-body length ( fig. 9 View FIG ; table 2 View TABLE 2 ). Members of the Long- Tailed Group are larger and have much longer tails. Rhoditis Group members C. rhoditis and C. pseudorhoditis are larger. Crocidura pallida and C. australis , also members of the Rhoditis Group, are only slightly larger than C. ordinaria in head-and-body length. Compared to C. ordinaria , C. pallida has paler feet dorsally, a narrower relative braincase breadth (BB/CIL) and a narrower relative interorbital width (IOW/CIL) whereas C. australis has a narrower relative interorbital width, but wider relative braincase breadth than C. ordinaria ( fig. 10 View FIG ). All members of the Small-Bodied Group are much smaller than C. ordinaria . Within the Ordinary Group, C. nigripes has darker feet and a relatively much narrower interorbital region and braincase than C. ordinaria . Compared to C. ordinaria , C. musseri has a thicker, darker pelage, and darker feet. Crocidura normalis is

darker in color, smaller in body size, has more bristles on its darkly colored tail, and its skull is narrower with a shorter relative rostral length (RL/CIL) than C. ordinaria . Crocidura solita , another member of the Ordinary Group, is difficult to distinguish morphologically from C. ordinaria . External measurements are nearly identical between these two species ( fig. 9 View FIG ), but C. ordinaria has a higher mass-to-length ratio ( fig. 17 View FIG ). The pelage and feet of C. ordinaria are darker and have a smaller hypothenar ( fig. 40 View FIG ), on average, than in C. solita . Cranially, C. ordinaria has a wider skull, observable in the absolute and relative breadths at the rostrum, interorbital region, and braincase ( figs. 10 View FIG , 42 View FIG ; table 14 View TABLE 14 ). Principal components analyses of external and cranial dimensions show that these two species overlap broadly in multivariate morphometric space, more so with external measurements than with cranial measurements ( fig. 43 View FIG ; tables 17, 18).
