First Record of Brown Forest Skink, Scincella Cherriei (Cope, 1893) (Squamata:Scincidae) in El Salvador Herpetology Notes, volume 13: 715-716 (2020) (published online on 25 August 2020) First record of brown forest skink, Scincella cherriei (Cope, 1893) (Squamata:Scincidae) in El Salvador Antonio E. Valdenegro-Brito1,2, Néstor Herrera-Serrano3, and Uri O. García-Vázquez1,* The Scincella Mittleman, 1950 genus is composed by 2015; Valdenegro-Brito et al., 2016; McCranie, 2018). 36 species, 26 restricted to eastern Asia and 10 species Here, we report the first record of S. cherrie from El are known in the New World in North America, and Salvador. The digital photographs of specimens were Mesoamerica (Myers and Donelly, 1991; Nguyen et al., submitted to the Colección digital de vertebrados de 2019). For El Salvador in Central America, Scincella la Facultad de Estudios Superiores Zaragoza, UNAM assata (Cope, 1864) represents the only species of (MZFZ-IMG). the genus know for the country (Köhler et al., 2006). While conducting fieldwork in El Salvador, on 10 Scincella cherriei (Cope, 1893) is characterised November 2019, we observed two male juvenile by possessing 30 to 36 rows of scales around the individuals (MZFZ-IMG254-56 and MZFZ-IMG257- midbody, 58-72 dorsal scales, thick and moderately 260; Fig. 1) of S. cherriei in a coffee plantation within long pentadactyl limbs, average snout-vent length of an oak pine forest in the locality of San José Sacare, 55 mm; the dorsal colouration is dark brown with a municipality of La Palma, Chalatenango department mottled pattern throughout the body, and a well-defined (14. 27079ºN, 89. 17995ºW; datum WGS84) 1215 lateral dark stripe only in the head and neck, which m a.s.l. The specimens were found active at twilight degrades to half a body; cream-yellowish belly; blue among the leaf litter. These specimens represent the tail with cross bands pattern (Stuart, 1940).

SEXUAL DIMORPHISM IN HEAD SIZE IN THE LITTLE BROWN SKINK (SCINCELLA LATERALIS) 1 BRIAN M. BECKER AND MARK A. PAULISSEN Department of Natural Sciences, Northeastern State University, Tahlequah, Oklahoma 74464, USA 1Corresponding author, e-mail: [email protected] Abstract.—Many species of skinks show pronounced sexual dimorphism in that males have larger heads relative to their size than females. This can occur in species in which males have greater body length and show different coloration than females, such as several species of the North American genus Plestiodon, but can also occur in species in which males and females have the same body length, or species in which females are larger than males. Another North American skink species, Scincella lateralis, does not exhibit obvious sexual dimorphism. However, behavioral data suggest sexual differences in head size might be expected because male S. lateralis are more aggressive than females and because these aggressive interactions often involve biting. In this study, we measured snout-to-vent length and head dimensions of 31 male and 35 female S. lateralis from northeastern Oklahoma. Females were slightly larger than males, but males had longer, wider, and deeper heads for their size than females. Sexual dimorphism in head size may be the result of sexual selection favoring larger heads in males in male-male contests. However, male S. lateralis are also aggressive to females and larger male head size may give males an advantage in contests with females whose body sizes are equal to or larger than theirs.

ABSTRACT The genus Scincella Mittleman, 1950 as currently recognized has been shown in numerous studies to be paraphyletic. Since the creation of the genus, some divergent species have been split off into separate genera (e.g. Kaestlea Eremchenko and Das, 2004 and Asymblepharus Eremchenko and Szczerbak, 1980) or transferred to others. Continuing with this dismemberment of the genus, this paper relies on both morphological and molecular evidence to further refine the genus-level classification of Scincella sensu lato. Four new genera for Asiatic species are formally erected according to the rules of the International Code of Zoological Nomenclature (Ride et al. 1999) as well as two subgenera within one of the new genera. Six obviously unnamed species are also formally named in this paper, so that their conservation and management can be properly implemented and before any species runs the increased risk of becoming extinct through indifference both by the scientific community and regulatory authorities who depend on them.

  • New Records and an Updated List of Herpetofauna from Cerro Piedra Larga, an Isolated Mountain Massif in Oaxaca, Mexico
    Herpetology Notes, volume 10: 651-658 (2017) (published online on 23 November 2017) New records and an updated list of herpetofauna from Cerro Piedra Larga, an isolated mountain massif in Oaxaca, Mexico Rafael Alejandro Calzada-Arciniega1,*, Ernesto Recuero2, 3, Mirna G. García-Castillo1 and Gabriela Parra-Olea1 Abstract. Oaxaca has the highest diversity of amphibians and reptiles of all the states in Mexico. Cerro Piedra Larga is an isolated mountain located in the southeast region of Oaxaca; this massif is covered by mixed temperate and cloud forest and surrounded by drier lowlands. A previous study reported a high diversity of vertebrate fauna on the massif, with 34 species of herpetofauna. During a sampling field trip to Cerro Piedra Larga in September 2014 we found a total of 22 species of amphibians and reptiles, 10 of which represent new records to the area, including six Mexican endemics. Our new records include two salamander species known previously only from their type localities in separate physiographic provinces and the others represent an extension to their geographical known distribution. With the new data we provide herein, Cerro Piedra Larga reaches 42 species of amphibians and reptiles.

However, previous studies revealed limited variability in cytoge- netic traits. The sex determination mode was revealed only in a handful of gerrhosaurid, skink, and xantusiid species, which demonstrated either ZZ/ZW or XX/XY sex chromosomes. In this study, we explored the karyotypes of six species of skinks, two species of cordylids, and one gerrhosaurid. We applied conventional and molecular cytogenetic methods, including C-banding, fluorescence in situ hybridization with probes specific for telomeric motifs and rDNA loci, and comparative genomic hybridization. The diploid chromosome numbers are rather conserved among these species, but the chromosome morphology, the presence of interstitial telomeric sequences, and the topology Citation: Kostmann, A.; of rDNA loci vary significantly. Notably, XX/XY sex chromosomes were identified only in Tiliqua scin- Augstenová, B.; Frynta, D.; Kratochvíl, L.; Rovatsos, M. coides, where, in contrast to the X chromosome, the Y chromosome lacks accumulations of rDNA loci.
