Neopodonomus similis Chaudhuri et Ghosh, 1981: 373–375 .

Boreoheptagyia similis (Chaudhuri et Ghosh) ; Serra-Tosio (1989: 167–168).

Diagnostic characters. The species was described by Chaudhuri & Ghosh (1981) from Bhutan in the Himalayas based on a single male. The male is characterized by: total length 3.12 mm; wing length 1.72 mm. Antenna with 13 flagellomeres, AR 0.15. Acrostichals 42 in 2 rows, dorsocentrals 16–20 in anterior and posterior groups, prealars 10. Scutellum with about 50 setae. LR 1 0.50, SV 1 3.7, BV 1 3.36.

Remarks. The description and figure of the male hypopygium of B. similis by Chaudhuri and Ghosh (1981) are not informative. A redescription based on the holotype and additional material is needed to enable us to compare this species with other members of Boreoheptagyia .

Distribution. The species is known only from the type locality in Bhutan.
