Morphological diagnosis. Cottus schitsuumsh is diagnosed from all other Cottus in the upper Columbia River basin by the lack of a second preopercular spine, palatine tooth patches smaller and separate from the vomerine tooth patch, and axillary prickling.
Cottus schitsuumsh is distinguished from C. cognatus, C. confusus, C. hubbsi, and C. rhotheus by the lack of a second preopercular spine. Cottus schitsuumsh is distinguished from C. cf. bairdii and C. beldingii by the presence of axillary prickling. In addition, C. schitsuumsh has palatine tooth patches smaller than the vomerine tooth patch and the patches are separated. Cottus cf. bairdii has palatine tooth patches equal to or larger in size than the vomerine tooth patch. Cottus beldingii generally lacks palatine teeth.
Molecular diagnosis. Haplotypes of C. schitsuumsh differed from those of all other members of the genus Cottus (represented in GenBank or in this study) at three positions (Table 1). Additionally, they differed from all other North American Cottus haplotypes at an additional position. Nucleotides at two other positions were diagnostic for individual haplotypes.

Description. Cottus schitsuumsh is a moderately sized species of Cottus rarely exceeding 90 mm SL with anal fin rays 14 (rarely 13 or 15), the final posterior anal-fin ray commonly branched; dorsal-fin spines 8 (rarely 7 or 9); dorsal-fin rays 17–20 (usually 18–19) with the posterior dorsal-fin ray branched; pectoral-fin rays 13–14 (usually 14); and pelvic-fin rays 4 (rarely 3) and of similar length. There are 2 medial-chin pores, 10–12 preoperculomandibular pores, and 2 postmaxillary pores (rarely 0). Dorsal fins are generally not connected but occasionally have a slight connection at the base. Prickling is consistent and restricted to a trapezoidal area, widest in the axillary region and narrowest along the lateral line under the beginning of the second dorsal fin. Palatine teeth are present in two or fewer rows and sometimes on only one side. The palatine tooth patches are smaller than and separated from the vomerine tooth patch and generally equal if present on both sides. The lateral line is incomplete, ending below the latter half of the second dorsal fin. One preopercular spine was observed among all specimens. Preopercular spines are greatly reduced and skin-covered. The mouth width/head width fraction ranges from ½ to 2/3.
Morphometrics of the holotype (91 mm SL, male) and 3 paratypes (57–73 mm SL, 2 males and 1 female) as a percentage of SL (mean and range): caudal peduncle depth (8.8, 8.1–10.6); caudal peduncle length (13.9, 12.3– 17.4); head length (19.7, 16.8–23.4); head width (26.8, 21.6–34.3); lateral line length (59.5, 51.3–70.6); snout length (9.0, 6.5–17.4); mouth width (14.2, 12.9–15.9); interpelvic width (3.5, 2.3–4.6); longest pectoral ray (24.3, 21.2–33.7), longest pelvic ray (18.5, 15.1–24.4).
Mottling of C. schitsuumsh is variable and consists of at least two forms. One has black-brown mottling on a brown-olive background mainly above the lateral line that stops under the soft dorsal fin (Fig. 4), and weak saddling is occasionally present (Fig. 5). The pectoral fins have faint black-brown contours running vertically. The other form lacks mottling or spotting over the body and the background color can be light brown, rust orange, or yellow. Both types have a dark blotchy marking near the base of the caudal rays and the first dorsal fin is generally dorsally darkened. Both forms are sympatric in the upper Spokane River basin, Idaho, but the mottled form has only been observed in Montana.
Comparisons. Cottus schitsuumsh tended to have more anal fin rays (mode, 14 rays) than the other species (modes, 12 or 13 rays) among our samples (Table 2) and relative to other sculpins in this region (Wydoski and Whitney 2003). Pelvic ray counts are similar among the observed Cottus species, but C. cognatus commonly had a greatly reduced fourth pelvic-fin ray (cf. Wydoski & Whitney 2003). Cottus rhotheus has more pectoral rays than C. schitsuumsh. Counts of medial-chin pores did not differ among species, although C. schitsuumsh tended to have more preoperculomandibular pores than other species and more postmaxillary pores than C. cf. bairdii, C. beldingii, and C. cognatus (Table 3). Cottus schitsuumsh can be further distinguished from C. cognatus and C. beldingii by the presence of palatine teeth (Table 4). The palatine tooth patch of C. schitsuumsh consists of two or fewer rows, may occur on only one side, and is about ½ the size of the vomerine tooth patch. The palatine tooth patch is similar to or larger than the vomerine tooth patch in C. rhotheus, C. hubbsi, and C. cf. bairdii. Cottus schitsuumsh also differs from C. hubbsi and C. rhotheus by having an incomplete lateral line.
Originally confused with C. confusus (Bailey & Bond 1963), C. schitsuumsh can be distinguished from it by having only one preopercular spine that is small (length less than half the eye diameter) and skin-covered (Fig. 6). Most specimens of C. schitsuumsh also lack lateral-line pores on the caudal peduncle (Fig. 7). Pores along the lateral line of C. confusus, usually end beneath the latter half of the second dorsal fin and reappear at the end of the caudal peduncle near the origin of the caudal rays.
1Fourth ray in the pelvic fin of C. cognatus reduced (ca. ½ of other rays; cf. Wydoski & Whitney 2003).
Most morphometric features separated C. schitsuumsh from one or more of the Cottus species. Caudalpeduncle depth, head length, mouth width, and interpelvic width statistically differed more often between C. schitsuumsh and the other species than did other measures (Table 5). Frequency distributions of these features emphasized these differences (Tables 6, 7). With respect to C. confusus, C. schitsuumsh differed by having a shorter lateral line, wider mouth, longer snout, and narrower interpelvic width.
Standardized head length Distribution and ecology. Cottus schitsuumsh is distributed in all streams sampled in the upper Coeur d’Alene and St. Joe River drainages of the Spokane River basin above Post Falls near Post Falls, Idaho, and sporadically in the middle Clark Fork River basin between Fish Creek and Prospect Creek, approximately between Tarkio and Thompson Falls, Montana (Fig. 1). This species is common to abundant in cool to cold tributaries with cobble and gravel bottoms. Cottus schitsuumsh is sympatric with Westslope Cutthroat Trout, Oncorhynchus clarkii lewisi, and Bull Trout, Salvelinus confluentus, throughout its distribution, with C. rhotheus in Idaho, and with C. cognatus in Montana. No effort was undertaken to find this species in Lake Coeur d’Alene or in the river main stems, but haplotype differences between fish from the Coeur d’Alene and St. Joe River basins imply that lineages in these basins are isolated and diverging.
The distribution in Idaho is consistent with that of other terrestrial and aquatic fauna e.g., Idaho Giant Salamander, Plethodon idahoensis, that persisted immediately south of the extent of Cordilleran glaciation in the Northern Rocky Mountain Refugium (Carstens et al. 2005; Shafer et al. 2010). The disjunct distribution in the Clark Fork River basin in western Montana is puzzling (although known for some time; Hendricks 1997). There are no known peri- or post-glacial hydrological connections between these basins because all mountain divides are more than 150 m above the glacial Lake Missoula highstand (Smith 2006). Because sculpins were a common and legal baitfish in Montana until this century, it is plausible that populations in western Montana resulted from human-assisted translocation. Regardless of their means of arrival, the Montana populations have haplotypes similar to those in the Coeur d’Alene River basin and probably originated from that watershed.
Etymology. The word schitsu’umsh (pronounced s-CHEET-sue-umsh) is Americanist phonetic notation of the spoken word used by the first peoples who inhabited portions of northern Idaho and western Montana, now recognized as the Coeur d’Alene Tribe. In modern usage it means “those who were found here” and refers to the people of this tribe. The current distribution of C. schitsuumsh overlaps with most of the historical homeland of this tribe. The common name refers to a common riparian tree in this area, Western Redcedar, Thuja plicata.
Remarks. Although originally assigned to C. confusus, a broad-scale genetic biodiversity inventory of fishes in the northern Rocky Mountains (Young et al. 2013) indicated, based on sequence differences among two mtDNA regions, that C. schitsuumsh was not closely related to that species. In the present study, the more geographically comprehensive sample of fishes subjected to genetic analysis coupled with the morphological assessment confirmed that interpretation. In a broader context, however, these findings support previous assertions that the taxonomy of sculpins in North America is far from resolved (Neely 2003; Kinziger et al. 2005; April et al. 2011). Paraphyly and polyphyly among a number of taxa are evident in phylogenetic trees based on COI (Fig. 2). Although partly attributable to a lack of resolution resulting from the limited number of nucleotides in this region (Pollock et al. 2002), the results are similar to those observed for other mtDNA regions that included additional taxa and more nucleotides (Kinziger et al. 2005; Young et al. 2013). In addition, the large genetic differences between clades within other species of Cottus in the western U.S., such as C. beldingii and C. confusus, suggest that additional taxa remain to be described (also see April et al. 2011).
The ambiguous morphological distinctions among sculpin species (Jenkins & Burkhead 1994; McPhail 2007) argue for the use of genetic information for species discovery and delineation (Baldwin & Weigt 2012). Moreover, some of the variation in diagnostic traits within species ascribed to geography may instead reflect the existence of cryptic taxa (Bickford et al. 2007). As has been suggested for other groups of species, an integrative taxonomy relying on morphology and genes will be necessary to understand the details of the systematic relations and boundaries of individual taxa among members of the genus Cottus.
