( Figs 22–26 )

Hydropsyche saranganica Ulmer 1951 , 229, Indonesia (Java).

Material examined. Andaman and Nicobar Islands Union Territory of India: Great Nicobar Island, 10 km. EW road, 12.xi.2018, Gopi & party ( NZC), 1 male .

Diagnosis. The male genitalia of H. saranganica are similar to those of H. dido Malicky & Chantaramongkol 2000 ( Philippines) and H. bonadea Malicky & Chantaramongkol 2000 (Sumatra) in the appearance of the long median keel of segment IX and the apicoventral setose lobe of segment X. However, it differs in having the median keel of segment IX directed posterad in lateral view; the dorsal interlobular gap is U-shaped in dorsal view; and the apical segment of each inferior appendage is slender and long. On the other hand, in H. dido , the median keel of IX is directed more nearly dorsad (posterodorsad) in lateral view; the dorsal interlobular gap is V-shaped in dorsal view; and the apical segment of each inferior appendage is thicker and shorter than in H. saranganica .

This species was reported from Great Nicobar Island by Malicky & Chantaramongkol (2000).

Distribution. India (Andaman & Nicobar Islands UTI, Great Nicobar Island), Indonesia (Bali, Java, Lombok, Sumatra), Solomon Islands.
