03ECA0093C4FC32C91B5F98EAC67FAC1.taxon	discussion	Remarks. Mey (1999) considered H. dolosa to be a synonym of H. formosana after examining one of type specimen of H. dolosa but Malicky and Chantaramongkol (2000) did not agree and considered them to be two different species with very small differences in their male genitalia (c. f. Malicky & Chantaramongkol 2000, 822 p). However, there are clear differences in segment IX (which Malicky & Chantaramongkol 2000 didn’t mention) on which the apical keel is relatively broad in lateral view (making sternum IX wide) in H. dolosa but the apical keel is relatively narrow in lateral view in H. formosana. Tergum X has apicoventral setose lobes (distal fingers) relatively short in H. dolosa and bent mesad near the base in dorsal view, but they are longer and lyre-shaped in H. formosana (bent in a semicircular manner at base then directed caudad in dorsal view). In addition, the apicodorsal lobe (dorsal ridge) of segment X is uniform and present at the base of the apicoventral setose lobes in H. formosana either with a relatively straight caudal edge or slightly indented in the middle, but in H. dolosa the apicodorsal lobe is bifid and represented as two separate cusps. Malicky (2013) said, “ Hydropsyche formosana Ulmer 1913 und H. dolosa Banks 1939: Obwohl Mey (1999) diese beiden für synonym hält, haben wir (M & C 2000) Zweifel daran geäussert. Die Frage bleibt für weitere Untersuchungen offen. ” [Hydropsyche formosana Ulmer 1913 and H. dolosa Banks 1939: Although Mey (1999) considered these two to be synonymous, we (Malicky & Chantaramongkol 2000) have expressed doubts about this. The question remains open for further investigation.] Recently, Malicky (correspondence 3 January 2025) suggested that our species also could be Hydropsyche fryeri Ulmer 1915 and said, “ I think that only DNA comparisons of specimens from the original localities can definitely answer the question. ” We agree that DNA is needed to help clarify the situation.	en	Pandher, Manpreet Singh, Kaur, Simarjit, Parey, Sajad Hussain (2025): New records of Hydropsychinae (Insecta: Trichoptera: Hydropsychidae) from Assam, India.

03ECA0093C4AC32E91B5FA0FAF41FCE5.taxon	diagnosis	Diagnosis. In the general shape and structure, the male genitalia of P. renatae are similar to those of Potamyia aureipennis Ulmer 1930 (reported from Sumatra), and Potamyia baenzigeri Malicky & Chantaramongkol 1997 (in Malicky 1997, reported from Thailand). In lateral view (Fig. 7) segment IX of P. renatae is similar to that of P. aureipennis but its anterolateral margin is relatively convex in P. aureipennis whereas in P. renatae the anterolateral margin is almost straight. Further, in dorsal view (Fig. 8) P. renatae somewhat resembles P. baenzigeri. However, in dorsal view (Fig. 8) the body of tergum X in P. renatae is bilobed and hooked apicomesad, the mesal lobe is reduced, and the dorsal interlobular gap is roughly U-shaped and very wide; whereas in P. baenzigeri the body of tergum X is bilobed, apically round, with its mesal lobes well defined by setose areas, and the dorsal interlobular gap is V-shaped and very narrow.	en	Pandher, Manpreet Singh, Kaur, Simarjit, Parey, Sajad Hussain (2025): New records of Hydropsychinae (Insecta: Trichoptera: Hydropsychidae) from Assam, India.
