Abstract: |
|
| |
|
New molecular
(Allozyme and 16S mtDNA sequence) and morphological data on
Euscorpius italicus (Herbst, 1800) (Scorpiones: Euscorpiidae)
reveal two groups of populations. One including E. italicus from
Italy, Switzerland, and Pindos Mts (Grece), and other, Greek populations
from the Zakynthos Island (formely described as E. i. zakynthi
Caporiacco, 1950) and the Peloponnese (formerly described as Scorpius
naupliensis C. L. Koch, 1837). The genetic divergence between these
two groups was similar or higher to that observed between other
congeneric species, i.e. fixed for private alletes at eight out of 18
allozyme loci and ~5% mtDNA sequence divergence. A morphological study
of the material covering the entire range of E. italicus (Italy,
Switzerland, Slovenia, Croatia, Albania, Greece, Turkey, Georgia, and
Russia) is consistent with genetic data. Euscorpius naupliensis
(C. L. Koch, 1837) (=E. i. zakynthi Caporiacco, 1950, sys. n.) from
Greece is restored from synonymy and elevated to the rank of species.
Its is diagnosed by a number of morphological features, i.e. the absence
of the esba external tricobothrial series on the
pedipalp patella, position of tricobothria on the pedipalp fixed finger,
and morphometric ratios. |

Resumen: |
|
| |
|
Nuevos datos
moleculares (secuencia de alozimas y 16S mtDNA) sobre Euscorpius
italicus (Herbst, 1800) Scorpiones: Euscorpiidae) revelan la
existencia de dos grupos de poblaciones. Uno incluye a E. italicus
de Italia, Suiza y los montes Pindos (Grecia), y el otro las poblaciones
griegas de la isla de Zakynthos (descrita como E. i. zakynthi
Caporiacco, 1950) y el Peloponeso (descrita como Scorpius naupliensis
C. L. Koch, 1837). La divergencia genética entre estos dos grupos era
similar o mayor que la observada entre otras especies congenéricas, i.e.
fijada para elelos privados en 8 de 18 loci de alozimas y ~5% de
divergencia en la secuencia de mtDNA. El estudio morfológico del
material que cubre todo el área de E. italicus (Italia, Suiza,
Eslovenia, Croacia, Albania, Grecia, Turquía, Georgia y Rusia) concuerda
con los datos genéticos. Se restituye Euscorpius naupliensis (C.
L. Koch, 1837) (= E. i. zakynthi Caporiacco, 1950, syn. n.), de
Grecia, anulando la sinonimia previa, y se eleva al rango de especie. Su
diagnosis viene definida por una serie de rasgos morfológicos, i.e. la
ausencia de la serie tricobotrial externa esba en la
patela pedipalpal, la oposición de los tricobotrios en el dedo fijo del
pedipalpo, y proporciones morfométricas. |
