Haplothrips incognitus Priesner, 1933: 349

( Fig. 18 )

This species remains based on a single female from Java, Buitenzorg, 2.v.1923. Studied at the Senckenberg Museum, Frankfurt, in 2018, it is a rather dark individual, with antennal segments IV–VIII dark brown, and all femora extensively brown ( Fig. 18 ). The sense cone formula is remarkable, two on III but three on IV, and among described Haplothrips species this is shared with only four other species. These are H. aliceae described above, also H. fici Mound & Minaei and H. lyndi Mound & Minaei from northern Australia, and H. williamsi Moulton from Hawaii. H. williamsi remains known only from the original eight specimens taken on Hawaii in 1929, and was described as having “legs yellow” and antennal segments “one and four to eight brown, and two and three light brownish yellow”. Mound and Matsunaga (2017) studied a paratype of H. williamsi from the Moulton collection, San Francisco, and stated “legs almost clear yellow” and illustrated this paratype as having antennal segment III yellow in contrast to uniformly brown segments IV–VIII. Both H. incognitus and H. williamsi have antennal segments VII and VIII closely joined, whereas in the other three species listed above antennal segment VIII is more elongate and narrowed to the base. H. incognitus is most similar to H. lyndi in colour and structure, but these two will need to be compared using fresh undamaged specimens.
