Male genitalia ( Figures 1-5 )

Sternite IX roundly three cornered in lateral view, with slightly excised cavity on each posterolateral margin; apicodorsally fused with preanal appendages; tergum IX small, slightly sclerotized, reduced to transverse band dorsally in lateral view. Tergum X very small, posterad, slightly pointed dorsoapically in lateral view. Preanal appendages each very broad, posterolaterallymesally roundly excised, setose in lateral view; broad in dorsal view, dorsobasal process of preanal appendage spine- like, curved ventrad in lateral view; arising laterally to tergum X in dorsal view, curved preapically. Ventral process of preanal appendage pointed, ventrad longer than dorsobasal process of preanal appendage in lateral view. Inferior appendages each sickle-shaped in lateral view, broad basally, curved apically, with broad, small basomesal process in lateral view; broad basally, constricted subapically in ventral view, setose apically. Phallic apparatus long, slender; phallotheca broad;endophallus membranous, with ventral constriction, sclerites clearly visible.

Diagnosis: This species is closely related to Plectrocnemia banksi Fischer, 1962 . However, in P. fischeri sp.nov. the preanal appendages are very broad with mesal excision on posterolateral margin in lateral new which is lacking in P. banksi .

Distribution: India: Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh.

Etymology: This species is dedicated to Dr. Fischer for his contribution to Trichoptera systematics.
