| Abstract | Common name: Diamond Darter. Conservation status: Listed as a “species of special concern” by West Virginia Division of Natural Resources. Extirpated from Tennessee (Etnier and Starnes 1993), Kentucky (Burr and Warren 1986), and Ohio (Trautman 1957). Systematics: Sister species of Crystallaria asprella (Wood and Raley 2000; Morrison et al. 2006). Identification: C. cincotta is overall translucent with silvery white ventral side of the body and head and four wide olive-brown saddles on the back and upper side. Preorbital blotch and 12–14 mid-lateral blotches along side (Welsh and Wood 2008). Longest known individual is 77 mm SL (Welsh and Wood 2008). D1 11–13 (12), D2 11–15 (13), A I, 11–13 (13), lateralline scales 83–93 (87), cheek scale rows 1–4 (2), opercle scale rows 1–4 (2). Pelvic fins with falcate posterior margin. Drawing by SAW, 75 mm SL male, Elk River, WV. Distribution: Extant population in the Elk River of Kanawha River drainage, WV (Cincotta and Hoeft 1987; Welsh and Wood 2008). The range previously included the Muskingum River, OH, Ohio River, OH, Green River, KY, and the Cumberland River drainage, KY and TN. Abundance: Rare, known from 12 individuals (Welsh and Wood 2008). Habitat and ecology: Collected from riffles and pools with <1.5 m depth, moderate flow, and sand, gravel, and cobble substrates (Osier 2005). Based on habitats used by its sister species (C. asprella), the Diamond Darter may also use areas of deeper pool and run habitats. Reproduction: George et al. (1996) reported on reproduction of the sister species, C. asprella; however, no information is available on reproduction of C. cincotta. Threats: Grandmaison et al. (2003) reported siltation from current landuse practices as a major concern for conservation of Crystallaria in the Elk River drainage. Conservation action: No current conservation action has been implemented. Environ Biol Fish (2009) 84:191–192 DOI 10.1007/s10641-008-9405-z |
