Short Communication an Extremely Low Genetic Divergence across the Range of Euscorpius Italicus (scorpiones, Euscorpiidae)
Little or no genetic divergence is detected using mitochondrial 16S rDNA sequence comparisons across the entire geographic range of the scorpion Euscorpius italicus (Herbst 1800) from Switzerland, Italy, Slovenia, Greece and Turkey. This is consistent with known absence of patterns of allozymes and morphological variation. Euscorpius italicus is found almost exclusively in human habitations. It...
متن کاملA double role of sperm in scorpions: the mating plug of Euscorpius italicus (Scorpiones: Euscorpiidae) consists of sperm.
Mating plugs occluding the female gonopore after mating are a widespread phenomenon. In scorpions, two main types of mating plugs are found: sclerotized mating plugs being parts of the spermatophore that break off during mating, and gel-like mating plugs being gelatinous fluids that harden in the female genital tract. In this study, the gel-like mating plug of Euscorpius italicus was investigat...
متن کاملA new species of Euscorpius (Scorpiones: Euscorpiidae) from southern Bulgaria
A new scorpion species, Euscorpius drenskii sp. nov., is described from the Western Rhodope Mts. in southern Bulgaria. It is characterized by an oligotrichous trichobothrial pattern, which shows a conspicuous loss of one trichobothrium in the external median patellar series (em = 3), also observed in E. carpathicus (Linnaeus, 1767) and the subgenus Alpiscorpius Gantenbein, Fet, Largiadèr & Scho...
متن کاملMorphology and function of male genitalia (spermatophores) in Euscorpius italicus (Euscorpiidae, Scorpiones): complex spermatophore structures enable safe sperm transfer.
The structure and function of the spermatophore of Euscorpius italicus are analyzed. We show how the spermatophore gets shaped from two hemispermatophores and for the first time the sperm transfer mechanism is shown in detail, illustrating function and importance of all complex lobe structures of an euscorpiid spermatophore. A detailed description of the interaction of spermatophore and female ...
متن کاملEuscorpius sicanus (Scorpiones: Euscorpiidae) from Tunisia: DNA barcoding confirms ancient disjunctions across the Mediterranean Sea
We used a DNA barcoding marker (mitochondrial cox1) to investigate the controversial natural occurrence of Euscorpius sicanus (C.L. Koch) in North Africa. We tested this hypothesis by comparing a sample collected from a mountain in Tunisia to disjunct populations in Sardinia, Malta, and Greece. Using these samples, and a few additional Euscorpius spp. from southern Europe as outgroups, we recon...
