Dinurothrips hookeri Hood

( Figs 1, 10 , 17 , 26, 27, 36 )

Head pale, pronotum pale with anterior margin red, meso- and metanotum pale with red line posteromedially, abdominal segments I–VIII pale with red internal pigment, IX–X dark brown (black in alive individuals; brown in washed specimens) ( Fig. 1 ). Antennal segment III with setae much shorter than the length of the segment ( Fig. 10 ). Dorsal setae with apex expanded. Head setae D3 expanded; setae D1 inserted anteriorly to setae D4 ( Fig. 17 ). Pronotum with sclerotized blotches (pale in washed specimens). Abdominal tergite II with a pair of spiracles; segments IX–X completely sclerotized; segment X with six anal setae shorter than the segment length ( Fig. 36 ). Spiracles with facets with one to four pores ( Figs 26, 27 ). Larvae II have been studied from Brazil from the states of São Paulo, Acre and Piauí from plants such as Impatiens balsamina , Mentha sp. and grasses (CHNUFPI).
