Deathstalker Scorpion near Tabuk – Record by Viv Wilson
The Deathstalker Leiurus quinquestriatus contains the
subspecies Leiurus quinquestriatus quinquestriatus and Leiurus
quinquestriatus hebraeus. The species has a wide range from Africa
(Algeria, Chad, Egypt, Ethiopia, Libya, Mali, Niger, Somalia, Sudan, Tunisia)
to Asia (Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi
Arabia, Sinai, Syria, Turkey, United Arab Emirates, Yemen). African populations
of this species correspond largely to the subspecies L. q.
quinquestriatus while those of Asian populations to L. q. hebraeus.
The Deathstalker is found upon a wide variety of substrates in arid &
semi-arid regions. This species is a retreat generalist and will modify and
occupy existing spaces under ground cover and debris. It may also adopt existing
burrows of other invertebrates and small vertebrates, as well as excavate
shallow burrows under rocks to 20 cm in depth. Adult specimens are 80–110 mm
total length and typically have a yellow to orange-yellow colour. The metasomal
segment V typically has a dark coloration restricted to the posterior 2/3 of
the segment with the amount and intensity of the dark coloration varying among
specimens. Older specimens may be darker in overall coloration and the dark
coloration of metasomal segment V faded, reduced or indistinct. Reported toxicity
levels indicate that this species possesses one of the most toxic venoms
described in scorpions. Despite this the majority of stings produce only localized
effects in up to 97% of victims which is probably due to the average quantity
of venom injected (0.225 mg) being small. However, the venom of this species
may be fatal in infants and children due to the effects being weight-dependent
but fatalities are uncommon in adults. This scorpion was found by Viv Wilson in
the desert near Tabuk and Viv has kindly allowed me permission to use his
excellent photos on my website which are shown below.
