Two newly introduced Heteroptera (Insecta: Hemiptera) species in Colombia: Brachyplatys subaenus (Plataspidae) and Thaumastocoris peregrinus (Thaumastocoridae) Author Forero, Dimitri text Papéis Avulsos de Zoologia 2021 2021-10-27 61 1 7 http://dx.doi.org/10.11606/1807-0205/2021.61.96 journal article 10.11606/1807-0205/2021.61.96 1807-0205 7177323 Brachyplatys subaenus (Westwood, 1837) ( Fig. 1 ) Remarks: The highest diversity of Plataspidae is found in tropical and subtropical regions of the Eastern Hemisphere, with a few species widely distributed in the temperate Palearctic ( Schuh & Weirauch, 2020 ). The first species of Plataspidae recorded from the Western Hemisphere was Megacopta cribraria (Fabricius, 1798) , discovered in the USA in 2009 (Eger et al., 2010). This species is found from China (temperate and tropical) to tropical Asia and Australia , and it is associated mainly with kudzu Pueraria montana var. lobata (Willd.) Maesen & Almeida , and which has been considered recently a pest of soybeans Glycine max (L.) (Ruberson et al., 2013). A second plataspid found in the Western Hemisphere is B. subaenus , which was first discovered in Panama in 2012, being also the first record from the Neotropical region ( Aiello et al., 2016 ). This species was initially misidentified in Panama as B.vahlii (Fabricius,1787) but later correctly identified as B. subaenus by Rédei (2016) . Rédei (2016) provided diagnostic characters that help identify this species and differentiate it from B. vahlii . Plataspidae species feed primarily on legumes ( Schaefer, 1988 ), being B. subaenus no exception, which is known to feed on a variety of legumes species in its native range in Indomalaya,although other plant species in various families have also been recorded as host plants ( Rédei, 2016 ). In the Neotropical countries in which B. subaenus has been found, it has been recorded on the following Fabaceae host plants: the cultivated Cajanus cajan (L.) Mill sp., Glycine max , and Mucuna pruriens (L.) DC ( Aiello et al., 2016 ; Añino et al., 2018 , 2020 ; Carmona-Ríos, 2019 ; Perez-Gelabert et al., 2019); the endemic and cultivated Phaseolus vulgaris L. (Perez-Gelabert et al., 2019), Gliricidia sepium (Jacq.) Kunth ex Walp. ( Añino et al., 2018 ; Carmona-Ríos, 2019 ); and the endemic Leptolobium panamense (Benth.) Sch.Rodr. & A.M.G.Azevedo ( Aiello et al., 2016 ) . It has also been found on the following non-Fabaceae host species: Bactris gasipaes Kunth , Schefflera actinophylla (Endl.) Harms ( Aiello et al., 2016 ) , and Zea mays L. ( Añino et al., 2020 ). In Colombia , B. subaenus has no recorded host plant species. Distribution: Known in the Neotropical region from Costa Rica ( Carmona-Ríos, 2019 ), Panama ( Añino et al., 2018 ), Dominican Republic (Perez-Gelabert et al., 2019), Guadeloupe ( Anonymous, 2020 ), and Ecuador ( Añino et al., 2020 ). Additional localities can be found on iNaturalist (http://www.inaturalist.org) for some of these countries. Newly recorded from Colombia from two localities, in Cali ( Valle del Cauca ) and Isla Grande (Bolívar). Examined material: COLOMBIA .
