A new genus and a new species of wasp-mimicking Harpactorini (Hemiptera, Heteroptera, Reduviidae, Harpactorinae), with an updated key to the Neotropical genera

Abstract

Quasigraptocleptes maracristinaegen. nov., sp. nov. (Hemiptera, Heteroptera, Reduviidae, Harpactorinae, Harpactorini) is described based on male and female specimens from Brazil. Photographs and comments about the syntypes of Myocoris nigriceps Burmeister, 1835, Myocoris nugax Stål, 1872, Myocoris tipuliformis Burmeister, 1838 and Xystonyttus ichneumoneus (Fabricius, 1803) are presented. The intra-specific variability and sexual dimorphic characteristics among specimens of Q. maracristinaesp. nov. are recorded. General characteristics of Hiranetis Spinola, 1837, Graptocleptes Stål, 1866, Quasigraptocleptesgen. nov. and Parahiranetis Gil-Santana, 2015, which seem to be closer genera, are compared, including those of the male genitalia of some species. A key to the species of Myocoris Burmeister, 1835, and an updated key to Neotropical wasp-mimicking Harpactorini genera are provided.

A new species of Neotropiconyttus Kirkaldy (Hemiptera, Reduviidae) in a cacao plantation from the Colombian Napo Province, including a key to species, and taxonomic notes of the genus

“…The identification of the specimen into the genus Neotropiconyttus was carried out employing the taxonomic keys proposed by Maldonado and Lozada (1992) , Gil-Santana (2015) , and Gil-Santana and Oliveira (2023) . Additionally, comparisons of the specimen found in the current study with photographs of the female syntype of N. alboannulatus (Figs 1–4 ), available on the website of the NHRS ( http://www2.nrm.se/en/het_nrm/a/neotropiconyttus_alboannulatus.html ), and examination of female syntypes of N. dama deposited in the MFNB (Figs 43–51 ) by the second author (HRG-S) allowed confirm this finding.…”

“…General terminology follows Schuh and Weirauch (2020) . Male genitalia terminology follows Gil-Santana et al (2013 , 2017 ), Gil-Santana (2016) , and Gil-Santana and Oliveira (2023) . The holotype was housed in the LEUA Collection.…”

“…In the Neotropics, the tribe Harpactorini of the subfamily Harpactorinae is the most diverse group within Reduviidae , with approximately 53 genera in the Neotropics ( Forero 2011 ; Gil-Santana 2015 ; Gil-Santana et al 2015 , 2017 ; Gil-Santana and Oliveira 2023 ). Different species of bugs ( Hemiptera : Harpactorini ), with bees and wasps, have been recognized as being involved in mimicry systems regarding the general body form, wing coloration, and characteristics concerning physical proportions (e.g., Champion 1899 ; Elkins 1969 ; Maldonado and Lozada 1992 ; Hogue 1993 ; Gil-Santana 2008 , 2015 , 2016 , 2022 ; Gil-Santana et al 2013 , 2015 , 2017 ; Castro-Huertas and Forero 2021 ).…”

“… Maldonado and Lozada (1992) presented a key to Neotropical wasp-mimicking Harpactorinae genera, which, in their view, helps to quickly sort out specimens from unidentified material, although this is a somewhat artificial way of grouping genera. The most updated version of their key was published by Gil-Santana and Oliveira (2023) , where they included the following genera: Acanthischium Amyot & Serville, 1843, Coilopus Elkins, 1969, Graptocleptes Stål, 1866, Hiranetis Spinola, 1837, Myocoris Burmeister, 1835, Neotropiconyttus Kirkaldy, 1909, Parahiranetis Gil-Santana, 2015, Quasigraptocleptes Gil-Santana & Oliveira, 2023, and Xystonyttus Kirkaldy, 1909. Gil-Santana and Oliveira (2023) also summarized the literature regarding these genera.…”
