The American genus Dactuliothrips (Thysanoptera: Aeolothripidae) with three new species

Abstract

Three new species of Dactuliothrips Moulton are described, two from Mendoza, Argentina and one from Southern California, USA: D. prosopis sp.n. from Prosopis alpataco (Fabaceae), D. monttea sp.n. from Monttea aphylla (Scrophulariaceae), and D. ephedra sp.n. from Ephedra sp. (Ephedraceae). A revised diagnosis and an illustrated identification key to the nine recognized species of Dactuliothrips are also provided. Pictures and notes about the host plants for the species from Argentina are included, together with new records for D. kaszabi from Argentina.

Does the Enigmatic Wightia Belong to Paulowniaceae (Lamiales)?

“…The analyses based on DNA sequences from the 10 combined chloroplast and mitochondrial regions and the complete chloroplast genome data do not support a clade of Wightia and Paulownia . Even though Wightia was placed variously in Scrophulariaceae s.l., Bignoniaceae or Paulowniaceae in Lamiales (Wallich, 1830; Bentham and Hooker, 1876; Hallier, 1903; Pennell, 1920; Campbell, 1930; Li, 1947; van Steenis, 1949; Lawrence, 1951; Willis, 1955; Hu, 1959; Maheshwari, 1961; Hong et al, 1998; Fischer, 2004), our results support Wightia as sister to Phrymaceae (BS = 84,100; PP = 1.00,1.00; Figures 2, 3) or sister to the Phrymaceae - Mazaceae clade (BS = 65; PP = 0.95; Supplementary Figure S4). The Wightia -Phrymaceae clade is then sister to the large clade that includes Orobanchaceae and Paulowniaceae with high support (Figures 2, 3).…”

“…has been controversial. Wightia includes two species distributed mainly in Burma, India, Malaysia, Nepal, Vietnam, and Yunnan of China (van Steenis, 1949; Maheshwari, 1961; Hong et al, 1998). It was initially placed in Bignoniaceae based on the characters such as seeds that are winged but without endosperm and extra-floral nectarines under the leaf surface (Wallich, 1830; Hallier, 1903; Campbell, 1930; Li, 1947; Lawrence, 1951; Maheshwari, 1961).…”

It was also included in Scrophulariaceae sensu lato on the basis of its two locular ovaries, and fruit dehiscing characters (Bentham and Hooker, 1876; Pennell, 1920; van Steenis, 1949; Willis, 1955; Hu, 1959; Hong et al, 1998). Recently Fischer (2004) mentioned that Wightia , together with Brandisia Hook.…”
