3 The subspecies name Xenorhabdus nematophila subsp. nematophila corrig. (Poinar and Thomas 1965) Akhurst 1983 is automatically created by the valid publication of Xenorhabdus nematophila subsp. bovienii corrig. Akhurst 1983 and the valid publication of Xenorhabdus nematophila subsp. poinarii corrig. Akhurst 1983 [Rule 40d (formerly Rule 46)].
4 If an author accepts the elevation of Xenorhabdus nematophila subsp. beddingii corrig. Akhurst 1986, the elevation of Xenorhabdus nematophila subsp. bovienii corrig. Akhurst 1983 and the elevation of Xenorhabdus nematophila subsp. poinarii corrig. Akhurst 1983 to full species status, then Xenorhabdus nematophila subsp. nematophila corrig. (Poinar and Thomas 1965) Akhurst 1983 should thereafter be designated simply as Xenorhabdus nematophila corrig. (Poinar and Thomas 1965) Thomas and Poinar 1979 (Approved Lists 1980).
