“…The lizards belonging to the Ophiodes Wagler, 1828 genus (Squamata, Anguidae, Diploglossinae), popularly known as glass snakes, glass lizards or smash breaks, are exclusively Neotropical and distributed from the east of the Andes to the southeast of South America (Borges-Martins 1998, Pizzato 2005, Barros & Teixeira 2007, Montechiaro et al 2011, Cacciali & Scott 2012, 2015, Oliveira et al 2016, Ortiz et al 2017, Entiauspe-Neto et al 2017. Some morphological characteristics include a small pointed head, elongated body and tail, and an absence of external vestiges of anterior limbs with rudimentary posterior limbs (Barros & Teixeira 2007, Montechiaro et al 2011, Cacciali & Scott 2012, 2015.…”

Lizards of the Ophiodes genus, popularly known as glass snakes, are exclusively Neotropical. Despite their wide geographic distribution, glass snakes are poorly studied and there are many knowledge gaps in their biology and ecology to be filled. In this context, the objective of this study was to analyze possible sexual and population morphological differences of Ophiodes striatus specimens collected from different municipalities in the state of Minas Gerais, Brazil. A total of 63 specimens belonging to the Herpetological Collection of the Federal University of Juiz de Fora -Reptiles (CHUFJF-Reptiles), collected between 1995 and 2015 were analyzed. All the specimens were necropsied and morphometric measures related to body and head were measured. The males and females analyzed showed similar morphometric measures, and there was no size-related sexual dimorphism. Principal component analysis did not group the analyzed specimens by sex or locality. A positive correlation was observed between the snout-vent length and the vestigial limb length. The present study brings new information related to sexual dimorphism and population morphometric variation of O. striatus, adding information that will help in better understanding the ecology, biology and evolution of the genus in Brazil.

Herein we studied the reproductive biology of a viviparous lizard (Mabuya dorsivittata) from the Wet Chaco region (northeastern Argentina) and compared the results with other populations from the espinal (central Argentina) and the Atlantic Forest (southeastern Brazil), and with other Neotropical species of Mabuya to better understand the possible causes of its reproductive phenotype variation. Males and females of M. dorsivittata from the Wet Chaco exhibited associated, seasonal, and annual reproductive cycles. Spermatogenic activity related positively to a lengthening photoperiod reaching maximum activity in late spring (December). Females displayed an extended gestation period of 11 months, from midsummer (February) to late spring or early summer (December) when births occur. embryonic development was associated with temperature and historical rainfall. litter size ranged from 3 to 8 (mean = 5.3 ± 1.3 SD) and increased with body size and body mass of females. Fat-body mass varied seasonally and was inversely correlated with spermatogenesis and to embryonic development. Females were larger in body size and interlimb length, and smaller in head length than males. We observed interpopulational differences in minimum body size, litter size, and timing of birth, probably as a result of phenotypic plasticity, genetic divergence or both.
