Abstract
The genus Rhyncholepta Bergroth, 1911 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Chlorocorini) is redescribed and five species-group taxa are recognized, keyed, their diagnostic characters illustrated, and the distribution reviewed. Among the five taxa, two species and one subspecies are recognized as new: Rhyncholeptagrandicallosagrandicallosa Bergroth, 1911 (Brazil, Ecuador, French Guiana, Guyana, Peru, Suriname), Rhyncholeptagrandicallosacentroamericanasubsp. n. (Belize, Costa Rica, Guatemala, Mexico, Panama), Rhyncholeptahenryisp. n. (French Guiana), Rhyncholeptameinanderi Becker & Grazia-Vieira, 1971 (Bolivia, Brazil, Ecuador, Peru), and Rhyncholeptawheelerisp. n. (Guyana). The structure of the male genital capsule was found to be the only reliable character for identifying species-group taxa. For this reason, a simultaneous application has been submitted to the International Commission on Zoological Nomenclature to set aside the non-informative female lectotype of Rhyncholeptagrandicallosagrandicallosa and replace it with the male neotype suggested herein. Based on the available label data and our field experience, most of the specimens were collected by various types of light traps in or near dense forests. Adults can be collected throughout the year.
Highlights
Bergroth (1911) described a new pentatomid genus, Rhyncholepta Bergroth, 1911, which included the new species Rhyncholepta grandicallosa Bergroth, 1911, from French Guiana
The genus Rhyncholepta was not mentioned during the following decades until Pirán (1956), who reported a male from Bolivia, provided a line drawing of the abdominal apex and the genital capsule in ventral view, and erroneously designated it as the allotype of Rh. grandicallosa
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)
Summary
Bergroth (1911) described a new pentatomid genus, Rhyncholepta Bergroth, 1911, which included the new species Rhyncholepta grandicallosa Bergroth, 1911, from French Guiana. Rhyncholepta grandicallosa differs from all three species of the Rh. meinanderi species-group by the following main characters: i) Genital capsule in ventral view with ventral rim apically bilobed, with small, shallow, V-shaped notch medially, hypandrial projections not visible in this view (Figs 30–35).
