Remarks.
Becker (1911)
firstly described
Hemisphaerisoma politum
from Taiwan and gave the figure of the head. De Meijere (1913) transferred it to
Chalcidomyia
, and gave the new name,
Chalcidomyia beckeri
(
Chalcidomyia politum
preoccupied by
Chalcidomyia polita
de Meijere (1910)
).
Thressa beckeri
(de Meijere) was treated as synonymy with
Thressa punctifera
(de Meijere) from Java by
Duda (1934)
, but
Sabrosky (1977)
accepted them as two distinct species.
