Neobiosella is a monotypic genus of caddisfly belonging to the family Philopotamidae.

[2] The sole species found in this genus is Neobiosella irrorata.

[4] Wise felt that a novel genus was appropriate for N. irrorata due to the absence of apical fork 1 in both wings being a characteristic not shared with any other species in the family Philopotamidae.

[4] Wise's original text (the type description) reads as follows: ANTERIOR WING short, broad, and well-rounded at apex.

ANTERIOR WING light testaceous strongly irrorated with fuscous.
