Synonyms[1][2]

The venom of Linothele sp has a median lethal dose of 0.6 mg / kg, two toxins, both of low molecular weight, were isolated in the venom, Ls1 and Ls2. These two toxins have been shown to be quite lethal to white mice by injection into the cerebroventricular region. The lethal dose of Ls1 and Ls2 is 24 and 19 μg / kg respectively, both toxins represent 0.21% and 0.43% of the weight of the whole venom.[4]
