Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

Lystra, ae, f., or ōrum, n., a city in Lycaonia, north-west of Iconium, Vulg. Act. 14, 8; 14, 21.
Hence, Lystrēni, ōrum, m., the inhabitants of Lystra, Lystrenes, Plin. 5, 32, 42, § 147.
