The Panchaetothripinae (Thysanoptera, Thripidae) of Brazil, with one new Caliothrips species

Abstract

The subfamily Panchaetothripinae has been consistently recovered as a monophyletic group within Thripidae, comprising 144 species in 43 genera. Usually associated with plant leaves, 21 species from 12 genera have previously been recorded in Brazil, several being pests of a wide range of cultivated plants. Here we record four species as new to Brazil, Bradinothrips williamsi, Caliothrips nanus, C. punctipennis and Parthenothrips dracaenae. Moreover, Caliothrips cangaceiro sp. n. is described, Hoodothripiella ignacio is considered a new synonym of Elixothrips brevisetis, and Caliothrips marginipennis is a new synonym of C. punctipennis. Furthermore, the previously unknown males of B. williamsi and Hoodothrips constrictus are described. Caliothrips fasciatus is withdrawn from the Brazilian Thysanoptera list of species. Illustrated keys to adults of species recorded in Brazil are provided, together with notes on biology and brief descriptions. Parthenothrips kobusi Deventer, known only from Java, is not a member of the Panchaetothripinae and is reclassified as Bolacothrips kobusi (Deventer) comb. n.

Unravelling the identity of pest thrips (Thysanoptera: Thripidae) of bananas (Musaceae) in Brazil

“…2C, D; Lima and Milanez 2013). More recently, Lima et al (2020) recorded E. brevisetis in Amazonas, Mato Grosso, Paraíba, and Sergipe on different plant species, as well as in Aratuba, Ceará, causing damage to banana plantations. Elixothrips brevisetis is remarkable for its expanded anal setae on abdominal segment X (Fig.…”

Problems with the Concept of “Pest” among the Diversity of Pestiferous Thrips

“…Other thrips species that are listed as pests have restricted distributions and thus have a relatively local economic impact; for example. Bradinothrips musae on banana trees in Brazil [11], or Ceratothripoides claratris as a virus vector on tomatoes in parts of southeast Asia [12]. At the opposite extreme there are polyphagous species such as Frankliniella occidentalis and Thrips tabaci whose feeding and virus vectoring have come to involve serious economic losses worldwide [13].…”

“…The Panchaetothripinae comprises about 150 species, of which the most well-known is the Greenhouse Thrips, Heliothrips haemorrhoidalis. First described from Europe, but native to South America [11,24], this thrips is now found throughout the world. In cool climates, it is usually found only in sheltered conditions, but in warmer climates it breeds readily out of doors.…”

Behavioral observations of larvae and adults of Dinurothrips hookeri Hood, 1913 (Thysanoptera: Thripidae: Panchaetothripinae)

“…is one of the two species described in the Neotropical genus Dinurothrips Hood, 1913. Unlike its congener D. vezenyii Bagnall, 1919, known only from southern Brazil, Argentina and Florida (USA) on grasses, D. hookeri is more widely recorded in several countries of the Americas (Mound and Marullo, 1996;Hoddle et al, 2012;Lima et al, 2020). Dinurothrips hookeri is associated to a wide range of plants, including horticultural and ornamental crops (Aster, Gerbera and Zinnia) (Wilson, 1975), but damages have been recorded only to banana (Musa sp.…”
