Scincidae
No full textSCINCIDAE UF 153513 (Fig. 62 in Krysko et al. 2011; MorphoBank M 88653) was reported as the Fire Skink, Lepidothyris fernandi (Burton 1836). However, W. Böhme and P. Wagner (personal communication) reidentified this photographic voucher as the Fire-sided Skink, Trachylepis perrotetii (Duméril and Bibron 1839), a morphologically similar species indigenous to a broad region extending from Senegal eastward to along the southern-facing coast of western Africa, into central Africa as far east as the northern Congo Republic (Schmidt 1919; Welch 1982). Gibbons et al. (2009) hypothesized that T. perrotetii would be introduced to Florida via the pet trade; however, they erroneously provided a photograph of L. fernandi as an illustration for T. perrotetii, thus illustrating the difficulty in distinguishing these two morphologically similar species.Published as part of Krysko, Kenneth L., Somma, Louis A., Rochford, Michael R., Gillette, Christopher R, Enge, Kevin M. & Cueva, Daniel, 2012, Taxonomic corrections of certain verified non-indigenous reptiles from Florida reported by Krysko et al.

(Western lineage; Figure 9). Amended diagnosis. Carapacial caudal notch narrow and triangular or U-shaped, contained wholly on the pygal and not extending onto peripheral set 11, and pygal with two serrations and without medial suture; Peripheral 11 with 1 serration; pleural scute set 1 does not overlap onto the nuchal; distal rib end of costal 1 enters middle of peripheral 3; posterior projection of the squamosal globular and obtusely angled in lateral aspect, usually upwardly inflected; dermal scale on the frontals reduced in size; processus trochlearis oticum relatively straight with a single distal protuberance; posterior margin of squamosal-opisthotic contact relatively straight in dorsal aspect; mandible relatively narrow with slender triturating surfaces. Although generally the caudal notch is small and triangular, observable variation occurs within the species.Published as part of Thomas, Travis M., Granatosky, Michael C., Bourque, Jason R., Krysko, Kenneth L., Moler, Paul E., Gamble, Tony, Suarez, Eric, Leone, Erin, Enge, Kevin M. & Roman, Joe, 2014, Taxonomic assessment of Alligator Snapping Turtles (Chelydridae: Macrochelys), with the description of two new species from the southeastern United States, pp. 141-165 in Zootaxa 3786 (2) on page 149, DOI: 10.11646/zootaxa.3786.2.4, http://zenodo.org/record/25300

Lampropeltis getula subsp. meansi Krysko & Judd 2006, ssp. nov.
No full textLampropeltis getula meansi ssp. nov. Common name. English: Apalachicola Lowlands Kingsnake; Spanish: Serpiente rey de las tierras bajas de Apalachicola. Holotype. UF 73433 (field tag DBM 1360), an adult male collected 9 June 1970 in the Apalachicola National Forest on FH13 ca. 3.2 km W SR 67, Liberty County, Florida, United States, by D. Bruce Means (Fig. 12). Paratypes. All specimens from the Eastern Apalachicola Lowlands: UF 55449, male, Liberty County, FL; UF 55365, male, Apalachicola National Forest, NFR 126, 0.1 km S NFR 111, Liberty County, FL; UF 55362, female, Apalachicola National Forest, NFR 107, 1.2 km E NFR 122, Liberty County, FL; UF 55421, male, Apalachicola National Forest, NFR 111, 1.6 km E NFR 120, Liberty County, FL; UF 55385, male, Apalachicola National Forest, SR 65, 4.8 km S Clio, Liberty County, FL; UF 73638, female, Apalachicola National Forest, SR 67, 12.8 km S Telogia, Liberty County, FL; UF 128273, male, Tate’s Hell Swamp, US 98, 0.8 km W Carrabelle, Franklin County, FL; UF 73639, male, Tate’s Hell State Forest, SR 65, 1.6 km S Whiskey George Creek, Franklin County, FL. Diagnosis. A largesized, polymorphic population of Lampropeltis getula distinguished from all others by its overall light dorsal coloration, having either narrow or wide crossbands with considerably lightened interbands, or being nonbanded (striped or patternless). Combinations of these basic phenotypes also occur regularly in the wild. The ventral pattern is also variable, being either bicolored, loose checkerboard with interspersed bicolored scales, or mostly dark. Description of holotype. 1040 mm SVL; 155 mm tail; on both sides of head: 1 + 2 oculars, 2 + 3 + 4 temporals, 7 + 7 supralabials, 9 + 9 infralabials; 52 subcaudals; 21 DSR at midbody; 211 ventrals; dorsal pattern nonbanded (patternless); ventral pattern bicolored cephalad with dark pigment suffused with bicolored scales caudally (Fig. 12). Variation. 250 mm to 1425 mm SVL; 1 + 2 oculars; arrangement of temporals (n = 95 head sides) 2 + 3 + 4 (74.7%), 3 + 3 + 4 (2.10%), 2 + 3 + 3 (9.47%), 2 + 2 + 4 (4.21%), 2 + 3 + 5 (3.15%), 2 + 2 + 3 (4.21%), 1 + 3 + 4 (1.05%), 1 + 3 + 3 (1.05%); 7 + 7 supralabials; infralabials (n = 91 head sides) 9 (54.9%), 10 (43.9%), 11 (1.0%); subcaudals in males 47 to 53 (mean = 50.6 ± S.E. = 0.43, n = 31), females 42 to 53 (mean = 45.5 ± 0.59, n = 17); 21 DSR at midbody; ventrals 206 to 222 (mean = 212.7 ± 0.47, n = 60). Dorsal pattern variable: crossbands wide (up to the entire body length) and numbering from 1 to 25 (mean = 16.0 ± 1.31, n = 26) in females and 1 to 23 (mean = 9.6 ± 0.82, n = 65) in males. Gradual ontogenetic interband lightening occurs on newborns’ normally black interbands on the anterior 1/2 to 3/4 of each scale, which varies from 25–100% of the intensity of the light crossbands in the adult stage (see Figs. 7, 8 in Means & Krysko 2001). Adults that possess interbands the same intensity of the light crossbands appear to be nonbanded (striped or patternless), but they can be distinguished from truly nonbanded morphs due to the difference in morphology between the light colored crossband and interband scale types (Means & Krysko 2001). Distribution. Found in the Eastern Apalachicola Lowlands in the Florida panhandle between the Apalachicola and Ochlockonee rivers and south of Telogia Creek, Franklin and Liberty counties. Individuals of this taxon are also occasionally found in the southwestern Apalachicola Lowlands on the western side of the Apalachicola River. Morphological intermediates (i.e., L. g. goini) between L. g. meansi and L. g. getula are found mostly in the surrounding region from southern Gulf and Franklin counties to the west, north to Calhoun County, and east into northern Liberty (north of Telogia Creek), Gadsden, Leon, Wakulla, and Jefferson counties. Etymology. The taxon name is a noun, named for Dr. D. Bruce Means in recognition of his discovery of the first known Eastern Apalachicola Lowlands kingsnake, as well as his contributions to our knowledge of the flora and fauna of the Coastal Plains. Remarks. In the early to mid 1970s, it was not uncommon to encounter up to five Lampropeltis g. meansi crossing roads during the spring mating season (Krysko & Smith 2005). However, after travelling thousands of kilometers and hours on these same roads during the 1990s, KLK found only one individual, which had just been killed by a vehicle (Krysko & Smith 2005). Due to the rarity and severely declining populations of nearly all Lampropeltis getula in Florida (Krysko 2001, 2002; Krysko & Smith 2005), L. g. meansi should be listed at the state and/or federal level.Published as part of Krysko, Kenneth L. & Judd, Walter S., 2006, Morphological systematics of kingsnakes, Lampropeltis getula complex (Serpentes: Colubridae), in the eastern United States, pp. 1-39 in Zootaxa 1193 (1) on pages 24-26, DOI: 10.11646/zootaxa.1193.1.1, http://zenodo.org/record/506431
