Abstract: |
|
| |
|
Herein we report two
further cases of metasoma duplication in buthid scorpions: a second
instar juvenile Tityus obscurus (Gervais, 1843) and an adult
female Centruroides nitidus Thorell, 1876. Both individuals were
born in captivity; the former died after its first ecdysis, but the
latter reached adulthood and reproduced normally. This represents the
first published record of the occurrence of such an anomaly in either
species. |

Resumen: |
|
| |
|
Se reportan dos casos
adicionales de duplicidad del metasoma en escorpiones Buthidae: una
ninfa I de Tityus obscurus (Gervais, 1843) y una hembra adulta de
Centruroides nitidus Thorell, 1876. Ambos individuos nacieron en
cautividad; el primero de ellos murió luego de su primera ecdisis, pero
el segundo alcanzó la adultez y se reprodujo normalmente. Este
representa el primer registro publicado de la ocurrencia de dicha
anomalía en ambas especies. |
