Resumen:
The ability of a genotype to control the stable development of a
phenotype under different environmental conditions may explain the level
of developmental instability. An indicator to developmental instability
is Fluctuating Asymmetry. Traits under pressures of sexual selection
exhibit greater values of asymmetry that others. These traits have more
physiological requirements during morphogenesis and a more complex
development. The aims of this work are to analyze asymmetry patterns of
genitalic and somatic traits in the scorpion Bothriurus bonariensis
(Bothriuridae) and to compare these values between central and
peripheral populations of its distribution. We observed that types of
asymmetry in genitalic traits differed in both populations. Also, traits
of the hemispermatophores (two halves that constitute the
spermatophore) showed the highest levels of fluctuating asymmetry,
particularly in those characteristics with important role for
insemination success. This work offers fundamental baseline knowledge
for further works focused on asymmetry of genitalia and mating success
in scorpions.
