The genus name of Halacsya is in honour of Eugen von Halácsy (1842–1913), an Austrian physician and botanist of Hungarian descent. The Latin specific epithet of sendtneri refers to Otto Sendtner, (1813–1859) a German botanist and phytogeographer. Halacsya sendtneri was first described and published in Exsicc. (Herb. Norm.) Vol.44 on page 103, n.º 4364 in 1902.
