Why in the News?
A report titled “Animal Discoveries 2023” by the Zoological Survey of India (ZSI) highlights significant new species findings in Maharashtra and across India.
New Species in Maharashtra:
Maharashtra recorded 14 new animal species in 2023, with two species reported for the first time in India.
Notably, among the 25 Arachnid species reported for the first time in India, two belong to Maharashtra—Steatoda Erigoniformis and Myrmarachne Spissa.
Steatoda Erigoniformis: It is a species of spider known for its resemblance to the more dangerous black widow spiders. They are commonly referred to as “false widow spiders.”
Myrmarachne Spissa: It is part of a group of spiders that mimic ants in appearance and behaviour, a trait known as myrmecomorphy. Previously reported in Sri Lanka, Myrmarachne Spissa’sdiscovery in Pune marks its first report from India, highlighting the region’s biodiversity significance.
Key Findings from the ZSI Report:

Back2Basics: Zoological Survey of India
The ZSI was set up by British zoologist Thomas Nelson Annandale, in 1916.
It is the premier taxonomic research organisation in India based in Kolkata.
It was established to promote surveys, exploration and research leading to the advancement of our knowledge of various aspects of the exceptionally rich animal life of India.
The ZSI had its genesis as the Zoological Section of the Indian Museum at Calcutta in 1875.
Since its inception, the ZSI has been documenting the diversity and distribution of the fauna of India towards carrying out its mandate of conducting exploration-cum-taxonomic-research programmes.
The ZSI has published an extremely large amount of information on all animal taxa, from Protozoa to Mammalia.
