status

 

Aspidoscelis deppii (Wiegmann, 1834)  

Distribution.

The species has a wide distribution from Morelos and Michoacan (Mexico) south to Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica.

Samples.

RCMX76 (female*) from La Sepultura, Chiapas, Mexico.

DNA taxonomy.

The MT-CYB sequence (294-bp) is 4% divergent from GenBank sequences of Aspidoscelis deppii   (KF555517-21) from Mexico (Playa Miramar, Tabasco). Despite the wide distribution, there are no studies on the intraspecific genetic variability of this species. It is a pity because this slight divergence in the MT-CYB could match with a different karyotype (see below).

Chromosomes.

In the genus Aspidoscelis   chromosomal number ranges from 2n = 44 to 2n = 56, with some species showing triploid numbers, such as Aspidoscelis tesselatus   (Say, 1823), with 69 chromosomes ( Walker et al. 1997). The 2n = 44 is the most common diploid number in this genus ( Carvalho et al. 2015). Therefore, a low diploid number could represent an ancestral condition. All-acrocentric karyotypes with 2n = 52 (28M + 24m) ( Lowe et al. 1970) and 2n = 50 (26M + 24m) ( Manríquez-Morán et al. 2000) were reported in Aspidoscelis deppii   from an unknown location and from Yucatan, respectively. Therefore, the two karyotypes differ in the number of macrochromosomes. Concurrently with Lowe et al. (1970), we found a 2n = 52 (28M + 24m) (Fig. 5D View Figure 5 ) all-acrocentric chromosome complement in our sample from Chiapas. This result is also consistent with phylogenetic relationships, since a diploid complement 2n = 52 (28M + 24m) was found in other two species so far analyzed, A. guttatus   Wiegmann, 1834 and A. lineattissimus   (Cope, 1878), which are closely related to A. deppii   ( Lowe et al. 1970; Carvalho et al. 2015).
