NEARCTIC REGION (DIPTERA: TACHINIDAE)

Abstract.—'^2LV!\t changes are needed for six Nearctic Tachina. Three valid names are
proposed: T. ampUforceps (Rowe, 1931) for T. hispida (Tothill, 1924), nee T. hispida
Robineau-Desvoidy (1830); T. dakotensis Townsend (1892) for T.florum Walker (1849),
nee T.florum Robineau-Desvoidy (1 830); and T. robinsoni (Townsend, 1915) for T. nitida
(van der Wulp, 1882), nee T. nitida Zetterstedt (1838). Three new names are proposed:
T. californimyia Arnaud for T. intermedia (Reinhard, 1 942), non T. intermedia Zetterstedt
(1844); T. nearctica Arnaud for T. spinosa (Tothill, 1924), non T. spinosa Zetterstedt
(1838); and T. oligoria Arnaud for T. latifrons (Tothill, 1924), non T. latifrons Meigen
(1824).
