Abstract
Five species of Hemerobiidae (Neuroptera) are recorded from Vietnam. Genus Semohemerobius Yang 1983 (= Mesohemerobius Nakahara 1966) is considered as a new synonym of the genus Remerobius Linnaeus 1758. Notiobiella nguyeni is described as a new species; Hemerobius subacutus (Nakahara 1966), Hemerobius harmandinus Navás 1910 and Psectra iniqua (Hagen 1859) are diagnosed.
