Discovery of Damarchus inazuma: A New Spider Species

Scientists have made a rare discovery of a new spider species, Damarchus inazuma, which exhibits a unique phenomenon called gynandromorphism.

Characteristics of Damarchus inazuma

• The spider's body is perfectly divided into two halves: 
  • One half is bright orange, exhibiting female characteristics like larger fangs.
  • The other half is grey, showing male traits such as smaller size.

Significance of the Discovery

• This spider is the first recorded case of gynandromorphism in the Bemmeridae family.
• It is only the third known example in the mygalomorph group, which includes tarantulas.
• Gynandromorphism is a rare condition where an organism has both male and female tissues and characteristics.

Discovery Process

• Researchers from Chulalongkorn University made the discovery in a forest area near Nong Rong, Thailand.
• Entomologist Chawakorn Kunsete was inspired by a photograph on Facebook by Mr. Surin Limrudee.
• Collaboration and further specimen collection confirmed it as a new species.
• Possible causes include disruptions in sex chromosomes and environmental factors.

Venom Concerns

• No formal studies on the venom of this species exist.
• Related families, such as Theraphosidae and Barychelidae, are known to have venom glands.
• Field observations suggest possible venomous traits due to aggressive displays and fang droplet production.

Conclusion

The discovery of Damarchus inazuma adds to the rare examples of biological duality, highlighting nature's wonders.
