Abstract
Selysiothemis nigra (Vander Linden, 1825) y Erythromma viridulum (Charpentier, 1840) se citan en la isla griega de Cefalonia por primera vez, sobre la base de datos fotográficos. Con la presente nota también se proporciona una lista actualizada de la odonatofauna de la isla.
Highlights
Xenarthra is a mammalian group that includes a wide variety of locomotions and lifestyles, including the digging armadillos and anteaters, completely arboreal modern sloths and extinct terrestrial giant ground sloths (Hautier et al, 2014)
We examined the complete collection of 21 entire skulls of Bradypus variegatus archived in the collections of the Departamento de Biología of the Universidad del Valle in Cali (Colombia) and Instituto de Ciencias Naturales of the Universidad Nacional de Colombia
The ventral aspect of the skull is not a perfect flat object, the authors considered that the two-dimensional approach applied implies a limited loss of information, and we proceeded with the morphometric analyses
Summary
Sloths present some anatomical features which are unique in mammals (Hautier et al, 2014; Galliari & Carlini, 2018), such as the variation in the number of cervical vertebrae the specific sequence of cranial suture closure (Rager et al, 2014; Montilla-Rodríguez et al, 2016), the synsacral number (MontillaRodríguez et al, 2016; Galliari & Carlini, 2018), the early ossification of the pubis and the phalanges and late ossification of the sternum (Hautier et al, 2011; Tague, 2019), architectural properties of forelimbParés-Casanova muscles (Olson et al, 2018). Xenarthra is a mammalian group that includes a wide variety of locomotions and lifestyles, including the digging armadillos and anteaters, completely arboreal modern sloths and extinct terrestrial giant ground sloths (Hautier et al, 2014). They are grouped together with anteaters in the order Pilosa Flower, 1883 (Hautier et al, 2014). Both of these characteristics reveal externally a partially muted function of the head within the whole animal (Montilla-Rodríguez et al, 2016)
