Heliothrips zucchi Mound & Monteiro

( Figs 14 , 23 )

Body color yellow. Antennal segment III with very short setae, much shorter than the length of the segment; segment VII length never longer than 55 μm ( Fig. 14 ). Dorsal setae simple with blunt to capitate apex. Pronotum with no sclerotized blotch. Legs with tibiae and basal half of femora brown ( Fig. 23 ). Abdominal tergite II with no spiracles; segment IX sclerotized on lateral thirds, X completely sclerotized; segment X with six anal setae shorter than the segment length. Spiracles with facets with one to five pores. Specimens have been studied from Adenanthera macrocarpa from the states of Minas Gerais and Santa Catarina, Brazil (CHNUFPI). Larvae of this species have shorter antennae than the two congeneric species treated in this work and can be successfully distinguished from them based on the characters in the key .
