I take great pleasure in naming this species in honor of the collector, 0. H. Swezey. It is allied to
Linionia (Liinonia) albitarsis
(Alexander)
and
Limonia
(L.)
subalbitarsis

, of the East Indies, differing in the small size and in the possession of two rostral spines on the ventral dististyle of the male hypopygium.
