Diagnosis

Body yellow; head and pronotum slightly shaded; antennal segments I–IV yellow, V–VI brown at apex, VII–VIII brown; fore wing banded, strongly shaded but with pale area sub-basally and apically. Head with few lines of sculpture posteriorly, ocellar setae I absent. Antennae 8-segmented, III & IV with forked sense cones. Pronotum without conspicuous reticulation, with two pairs of long posteroangular setae. Mesothoracic spinula present; metathoracic endofurca weak, without spinula. Metanotum with irregular sculpture medially; campaniform sensilla present; median setal pair short, arising behind anterior margin. Fore wing with first and second vein setal rows widely interrupted. Abdominal tergites with transverse lines of sculpture, lateral thirds with few sparse microtrichia; II–VIII with a pair of small and widely separated setae medially; VIII with dentate craspedum, spiracles with specialized area of granulate cuticle. Sternites with lobed craspedum; three pairs of long posteromarginal setae.

Male not studied.

Intraspecific variation

Pronotal posteroangular setae sometimes small.

Genus and similar species information

The genus Chaetanaphothrips includes 20 species, most of them restricted to Asia. These species have a specialized area of granulate cuticle around the spiracles on abdominal tergite VIII. There is only one other member of the genus recorded from Brazil. C. signipennis differs from C. orchidii in having ocellar setae I present, and the pronotum with only one pair of long posteroangular setae.

World distribution

Widespread in tropical and subtropical countries, especially in the Americas.

Life history

Breeding on leaves of many unrelated plants, including orchids (Orchidaceae), Musa sp. (Musaceae), Citrus (Rutaceae), and some greenhouse plants.

Economic importance

Causing damage on banana fruits and leaves (Hoddle et al. 2012). In Brazil this species was reported damaging Anthurium plants (Araceae).
