Genus: Birulatus
Species: astartiae
Middle East
Taxonomy and Biology
Adult Length ( mm ): 15 mm
Overall colour is pale yellow to reddish yellow with granulation and keels marked with brown. Carapace is reddish yellow with black pigment surrounding median eyes. Tergites are reddish yellow with tergite VII paler than preceding tergites. Metasomal segments and telson vesicle are yellow. Aculeus is yellowish at the base and becoming reddish towards the tip. Ventral surface is paler yellow. Chelicerae are yellowish with pale reddish teeth. Pedipalp femur and patella is reddish yellow and paler than the body. Chela is yellowish ( including granular rows on dentate margins ). Legs are yellowish.

Clinical Effects
General: Dangerousness
Unknown; there are a number of dangerous Buthid scorpions, but also others known to cause minimal effects only. Without clinical data it is unclear where this species fits within that spectrum.
General: Rate of Envenoming: Unknown
General: Untreated Lethality Rate: Unknown but lethal potential cannot be excluded
General: Local Effects
Unknown; however, in general, Buthid scorpions cause locally painful stings
General: Local Necrosis
Unknown; unlikely based on experience with other Buthid scorpions
General: General Systemic Effects
General: Myotoxicity
Unknown; unlikely based on experience with other Buthid scorpions
General: Renal Damage
Unknown; unlikely based on experience with other Buthid scorpions
General: Cardiotoxicity
Unknown; possible given experience with medically important Buthid scorpions
General: Other
First Aid
Description: First aid for scorpion stings (in areas where no potentially dangerous species may be found)
1. Reassure the victim. Despite sometimes intense local pain, usually lasting less than one hour, these scorpions are not able to cause major of lethal envenoming and most stings will settle rapidly.
2. Do not apply a bandage or tourniquet, or cut, suck or incise the wound or apply electric shock. Neither the application of local heat or cold are proven as effective.
3. If the victim develops general symptoms or the pain remains severe after one hour, seek medical advice.
Treatment Summary
Stings by these scorpions are likely to cause only short lived local effects, such as pain, without systemic effects. Treatment is therefore reassurance and symptomatic, with analgesia only for severe and persistent pain, as short lived pain will likely resolve before analgesics can take effect. Update tetanus immune status. Be more cautious in young children, observing for several hours post-sting. No antivenom is available, or is required.
Key Diagnostic Features
Not well defined. Most likely limited to local pain ± local swelling, without significant systemic effects. See detailed clinical summary for more specific detail, if known.
General Approach to Management
Most cases will be minor & not require admission.
