The New World grass‐thrips genus Plesiothrips (Thysanoptera: Thripidae) and its palaeotropical relationships

Abstract

Morphological character states displayed by Plesiothrips Hood, a New World genus of grass-living thrips, are assessed. This assessment indicates that Plesiothrips shares more character states with genera from Southeast Asia, including the Trichromothrips genus-group, than with any New World Thripinae. Sorghothrips sakagami (Kudo) comb. n. is removed from Plesiothrips; Taeniothrips aberrans Crawford syn. n. is considered a new synonym of Plesiothrips amblycauda Hood; and an illustrated identification key is given to 16 Plesiothrips species for which females are known.

<b>New reports of thrips (Thysanoptera: Terebrantia: Thripidae) from India</b>

“…The collected specimens were preserved in collection fluid (nine parts 10% alcohol + one part glacial acetic acid + one ml Triton X-100 in 1000ml of the mixture). Specimens were balsam mounted for permanent preservation (Ananthakrishnan & Sen 1980) and they were subsequently sorted out and identified with the help of standard keys (Mound 1999;Mound et al 2016;Tong et al 2016). The images of all the three species were photographed with the help of a binocular research microscope.…”

“…Moreover, the anterior ocellus is situated anterior to frontal margin of compound eyes; and females have a highly reduced ovipositor, without reaching the apex of abdomen. Males have unusually small antennal segment III and greatly enlarged segments IV-VI with numerous long setae; tergite IX bears a pair of drepanae and sternites III and IV bear a pair of circular pore plates (Mound et al 2016).…”

First record of Caliothrips phaseoli Hood, 1912 (Thysanoptera: Thripidae) causing damage to forage grasses

“…Many Thysanoptera groups are associated with forages. Most of them, such as Bregmatothrips Hood, 1912, Chirothrips Haliday, 1836and Plesiothrips Hood, 1915, are associated with Poaceae species (Mound 2011;Nakahara & Footit 2012;Mound et al 2016), and a few have been reported as occurring in or damaging legume pastures, such as Enneothrips enigmaticus Lima et al, 2022 (Thysanoptera: Thripidae) in Arachis pintoi Krapov & W.C. Gregory (Fazolin et al 2015;Lima et al 2022).…”
