Description Present study deals with new distributional records of Strongylura incisa (Belonidae) based on five specimens collected from the
Andaman Islands and Tuticorin Coast (Tamil Nadu), India during 2016–17. Specimens were identified by absence of scales at bases
of dorsal and anal fins, 19–20 dorsal fin rays, 21–23 anal fin rays, 102–113 predorsal scales, dorsal fin origin over 4–5 anal fin rays,
prominent elongate spot on cheek between opercle and preopercle, and double lobe of gonad. Strongylura incisa can be distinguished
from itsmost similar congener S. leiura based on number of predorsal scales (100–125 in S. incisa versus 130–180 in S. leiura), dorsal
fin origin over anal fin rays (4–6 in S. incisa versus 7–10 in S. leiura), number of gonad lobes (2 in S. incisa versus 1 in S. leiura) and
colour characteristics (prominent elongate spot on cheek between opercle and preopercle in S. incisa versus black bar on cheek
between opercle and preopercle and anterior region of the body in S. leiura). Present study provides the first documented record of
S. incisa from the Andaman and Nicobar Islands and East Coast of India with an updated key for Strongylura species. Further, it is an
addition to the ichthyofaunal biodiversity of the Andaman and Nicobar Islands and East Coast of India.
