Elixothrips brevisetis (Bagnall)

( Figs 11 , 30 )

Body color yellow with head and abdominal segments IX and X brown; sclerotized blotches brown in unwashed specimens.Antennal segment III with setae much shorter than the length of the segment ( Fig. 11 ). Dorsal setae minute with acute apex. Head setae D1 inserted anteriorly to setae D4. Pronotum with sclerotized blotches. Abdominal tergite II with no spiracles; segment X with six minute anal setae. Spiracles with facets with one pore ( Fig. 30 ). Immatures of this species have been collected from banana fruits in the state of Santa Catarina ( Lima & Milanez 2013) (CHNUFPI). We were not able to find reliable characters to distinguish available specimens of E. brevisetis and Hoodothrips lineatus . Larva II of this species is also similar to Hercinothrips spp. , but does not have spiracles on abdominal tergite II, and setae on tergites IX–X do not emerge from robust tubercles. Setae D1 on abdominal tergite IX are less robust than in H. bicinctus , and more similar to H. femoralis . However, segment IX is completely sclerotized as in H. bicinctus .
