	Hyla	Will find all records that contain stand-alone uses of Hyla: e.g., Hyla, Hyla arenicolor
Strings of words without quotation marks	Lithobates pipiens	Interprets this as "Lithobates OR pipiens" so will find the union of all records that contain either "Lithobates" or "pipiens": e.g., Lithobates omiltemanus, Hylorana pipiens
Strings of word with quotation marks	"Lithobates pipiens"	Interprets this as "Lithobates AND pipiens" so will return all records that have the character string "Lithobates pipiens" anywhere within a record: e.g., all members of the Lithobates pipiens complex.
AND statement. Means that the results of the search must include both words held together by an AND	Lithobates AND pipiens	Same as "Lithobates pipiens"
OR statement. Means that the results of the search will all records that have either of the terms held together by an OR	Lithobates OR "Costa Rica"	Recovers all records that contain the word "Lithobates" or "Costa Rica": 402 records inasmuch as this will include all records for the entire amphibian fauna of Costa Rica
Combining Boolean operators within the Basic Search box (AND, OR, NOT, quotation marks)	Lithobates AND "Costa Rica" NOT forreri	Recovers only records that contain the word Lithobates AND "Costa Rica", but excludes any record that contains the word "forreri" in any part of the record: 9 records

English Names

Blue Ridge Dusky Salamander (Tilley and Mahoney, 1996, Herpetol. Monogr., 10: 27; Collins, 1997, Herpetol. Circ., 25: 6; Tilley, Highton, and Wake, 2012, in Crother (ed.), Herpetol. Circ., 39: 16; Collins and Taggart, 2009, Standard Common Curr. Sci. Names N. Am. Amph. Turtles Rept. Crocodil., ed. 6: 12; Tilley, Highton, and Wake, 2012, in Crother (ed.), Herpetol. Circ., 39: 26; Powell, Conant, and Collins, 2016, Field Guide Rept. Amph. E. North Am., 4th ed.: 49; Highton, Bonett, and Jockusch, 2017, in Crother (ed.), Herpetol. Circ., 43: 26).

Distribution

From Floyd County, Virginia, to between Linville Falls and McKinney Gap on the Blue Ridge Divide (Burke and McDowell counties, North Carolina) and to the headwaters of Toms and Clark Creeks ca. 1.5 miles northeast of Iron Mountain Gap on the North Carolina-Tennessee boundary (Mitchell–Unicoi counties), USA.

Comment

See comment under Desmognathus carolinensis. Tilley and Mahoney, 1996, Herpetol. Monogr., 10: 1–42, Tilley, 1997, J. Heredity, 88: 305–315, and Highton, 2000, in Bruce et al., Biol. Plethodontid Salamanders: 233, suggested that two species might be covered under this one name. Mead, Tilley, and Katz, 2001, Evolution, 55: 2287–2302, discussed molecular geographic variation in the species. Camp and Tilley, 2005, in Lannoo (ed.), Amph. Declines: 721–723, provided an account containing a detailed summary of the literature and range. Kozak, Larson, Bonett, and Harmon, 2005, Evolution, 59: 2000–2016, provided a molecular phylogenetics study that suggested two species under this name. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 422–423, provided a brief account, photograph, and range map. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 105–106, provided an account of larval morphology.
