Stink bugs (Hemiptera: Pentatomidae) from Brazilian Amazon: checklist and new records

Abstract

A list of the stink bugs (Pentatomidae) species of the Brazilian Amazon is provided for the first time, based on literature review and identification of the specimens of Pentatomidae deposited in the entomological collection of the Museu Paraense Emílio Goeldi (MPEG). Amazonian data base presented here has 324 species of Pentatomidae belonging to 102 genera, ten tribes and five subfamilies: Asopinae, Cyrtocorinae, Discocephalinae, Edessinae and Pentatominae. The Pentatominae has the largest number of species registered to Brazilian Amazon (144 species). The MPEG entomological collection has 122 species distributed in 53 genera, nine tribes and five subfamilies. Forty species from eight tribes and four subfamilies are recorded for the first time to Brazilian Amazon, including species from Podisus Herrich-Schäffer (Asopinae); Adoxoplatys Breddin, Macropygium Spinola, Neoadoxoplatys Kormilev, Ochlerus Spinola and Platycarenus Fieber (Discocephalinae); Edessa Fabricius (Edessinae); Arocera Spinola, Arvelius Spinola, Banasa Stål, Dichelops Spinola, Euschistus Dallas, Mormidea Amyot & Serville, Oebalus Stål, Pellaea Stål, Piezodorus Fieber, Proxys Spinola and Thyanta Stål (Pentatominae). Three of these species–Podisus maculiventris (Say, 1831) Neoadoxoplatys saileri Kormilev, 1956 and Edessa laticornis Stål, 1872—are new records to South America. The number of species of Pentatomidae to Brazilian Amazon represents approximately 50% of the species registered to Brazil. Such list of species is important to better understand the distributional range and diversity of the species of Pentatomidae in the Amazon region.

The first extensive analysis of species composition and abundance of stink bugs (Hemiptera: Pentatomidae) on soybean crops in Brazil

“…45 Its occurrence in the United States has been reported since the early 1900s, 44 and more recently it has been considered one of the main soybean pests in the southern United States. 44,46 In Brazil, P. guildinii is recorded from Amapá to Rio Grande do Sul 47 and it has been reported as one of the most abundant species in soybean fields since the 1970s, mostly in the southern states. 48,49 In our sampling we observed that the relative abundance of P. guildinii was low, less than 1.5% overall, but consistently occurring in all soybean macroregions and varying from c. 5% of the adults collected in MR1 to less than 1% in MR2 and MR4.…”

Review of the Neotropical genus Rhyncholepta with descriptions of three new species-group taxa (Hemiptera, Heteroptera, Pentatomidae)

“…]: 563 (record); Rider et al (2018): 190: fig. 2.21 (habitus photo, distribution); Silva et al (2018): 437 (checklist).…”

“…Brazil: Amazonas (Becker and Grazia-Vieira 1971, Arnold 2011, Silva et al 2018); ?Colombia: Chocó (Torres Gutiérrez 2005, as Rhyncholepta sp. ; Castro-Huertas et al 2015); French Guiana (Becker and Grazia-Vieira 1971); Guyana (new country record); Peru (new country record); Suriname (new country record); Venezuela (Becker and Grazia-Vieira 1971, Grazia 1984).…”

“…Rolston and McDonald 1981, 1984; Rolston et al 1980). Rhyncholepta since has been included in a generic key by Torres Gutiérrez (2005), and several authors have provided new distributional records or checklists from Honduras, Panama, Colombia, Venezuela, Brazil and Peru (Grazia 1984, Froeschner 1999, Arismendi and Thomas 2003, Arnold 2011, Castro-Huertas et al 2015, Cambra et al 2018, Rider et al 2018, Silva et al 2018). Greve et al (2013) included Rh.grandicallosa , along with Loxadeducta Walker, 1867 and Mayriniacurvidens (Mayr, 1864), as out-groups in their cladistic analysis of Chloropepla Stål, 1867, considering them closely related (based mainly on the presence of the hypandrium on the ventral wall of the genital capsule).…”
