Bioacoustics of Grandidierella khambhatensis

Remarks Grandidierella khambhatensis sp. nov. described here appears to be very close to G. perlata Schellenberg, 1938 in having the following character states: male gnathopod 1 carpus anterior margin almost straight, posterior margin with undulations; propodus anterior margin convex, posterior margin almost straight with two knobs. However, G. khambhatensis sp. nov. can be differentiated from G. perlata in having following characters: male gnathopod 1 basis anterodistal corner produced into a well-developed rounded lobe ( Fig. 7G 1 ) (versus posteroventral lobe not well-developed in G. perlata , Schellenberg (1938) ; Fig. 46a); male gnathopod 1 carpus posterior margin with weak undulations, posterodistal corner tooth with blunt end and no stridulating organs ( Fig. 7G 1 ) (versus posterior margin with strong undulations, posterodistal corner tooth with sharp end and presence of stridulating organs in G. perlata, Schellenberg (1938) ; Fig. 46a); male gnathopod 1 propodus posterior margin with two rectangular knobs ( Fig. 7G 1 ) (versus knobs more rounded in shape in G. perlata, Schellenberg (1938) ; Fig. 46a); male gnathopod 2 propodus posterior margin convex with smooth ridges and palm oblique ( Fig. 7G 2 ) (versus propodus posterior margin straight with crenated ridges and palm straight in G. perlata, Schellenberg (1938) ; Fig. 46b); uropod 3 ramus hook shaped ( Fig. 6U 3 ) (versus ramus rod shaped-straight).
