Research paper thumbnail of The occurrence of new records of Hydroidolinae (Cnidaria: Hydrozoa: Diphyidae) collected from shah bunder creek, Indus deltaic area (Pakistan)

The genus Lensia has 37 species, which are found all over the world. It is the most diverse genus of the Hydroidolinae. Only five species have been recorded in Pakistani waters. However, three species, Lensia meteori (Leloup, 1934), L. hardy Totton, 1941 and L. havock Totton, 1941 are new occurrence of Shah Bunder creek, Indus deltaic area. An identification key and morphological description of these three species are presented in this study.

Organisms found on rocky shores are facing intense physicochemical conditions during tidal changes from upper to lower intertidal zones. Total (N=1888) specimens were collected on seasonal basis from intertidal zone during low tide from two rocky sites of Karachi coast, Buleji and Sunehri during January 2017 to December 2017. The highest number of individuals (N=1041), were recorded from Buleji than Sunehri (N= 847). The seasonal abundance in Mollusca were measured as (36.84%), (63.67%), (25.08) and (40.38%) from Buleji while from Sunehri (45.16 %), (46.01%), (48.65) and (42.79 %) during pre-monsoon, southwest monsoon, post monsoon and northeast monsoon season respectively. Group Arthropoda, Mollusca and Echinodermata were shows the highest abundance of the species at both sites as compare to other groups. The highest diversity index from Sunehri (H'=0.64) was measured in northeast monsoon season meanwhile, (H'=0.61) was measured in post monsoon season from Buleji coast. Evenness index (J'=0.25) in pre-monsoon season from Buleji and (J'=0.28) in southwest monsoon season from Sunehri coast. Season shows the great abundance of species as compare to other seasons. No significant correlation was observed in between seasons, water temperature and salinity with macrofauna groups at both sites.

Adult specimens of A. cornigera were collected from Buleji on 23rd of January, 2017 and kept in aquaria under controlled laboratory conditions until they laid eggs and hatching occurred. This is the first report of Aplysia (V.) cornigera from Pakistan.
