Lima, Élison Fabrício B., O’Donnell, Cheryle A., Sousa, Yago Lucas C. & Zamar, María Inés, 2021, Identification of second instar larvae of Panchaetothripinae (Thysanoptera Thripidae) in Brazil and Argentina, Zootaxa 5047 (4), pp. 453-464 : 457

Heliothrips haemorrhoidalis (Bouché)

( Figs 12 , 18 , 31 )

Body color yellow. Antennal segment III with setae shorter than the length of the segment; segment VII length usually 70 μm ( Fig. 12 ). Dorsal setae simple with blunt to capitate apex ( Fig. 18 ). Pronotum with no sclerotized blotch. Abdominal tergite II with no spiracles; segment IX sclerotized laterally, X completely sclerotized; segment X with six anal setae shorter than the segment length. Spiracles with facets with one to five pores ( Fig. 31 ). In Brazil, this species has been found only recently in the Atlantic Rainforest biome ( Lima et al. 2020). Immatures have been collected from Anthurium leaves in the state of São Paulo, Brazil (CHNUFPI). The authors could not find consistent differences between larvae of this species and H. longisensibilis . However, the antennal segments of H. longisensibilis are usually shorter than in H. haemorrhoidalis .
