Dendrothripine thrips are distinguished from other members of Thripidae by a remarkably elongate, “lyre-shaped” metasternal endofurca. This furca extends to the mesothorax as a pair of sinusoidal curved spurs, providing the insertion points for powerful muscles arising from the hind legs of the salatatorial thrips. The subfamily Dendrothripinae, formerly known for a long time as the tribe Dendrothripini since Priesner (1925), was up-ranked to subfamily level of Thripidae by Bhatti (1989). Of the 97 species in 15 genera known worldwide, Dendrothrips minowai Priesner, 1935 and Pseudodendrothrips mori (Niwa, 1908) have been hitherto reported from Korea. In this study of the Korean Dendrothripinae, two species of genus Dendrothrips, D. ornatus (Jablonowski, 1894) and D. magnoliae Kudo, 1984, are found for the first time. However, D. minowai Priesner recorded by Woo (1974), is excluded from the Korean fauna because of misidentification as supposed by Kudo (1984). Morphological characters for identification of three species including P. mori previously recorded are described and figured with a key to Korean species of Dendrothripinae.
