A new genus and a new species of Ectrichodiinae from French Guiana and an updated key to the genera of the New World (Hemiptera, Reduviidae)

Abstract

Amazopothea guilbertigen. nov. et sp. nov. belonging to the subfamily Ectrichodiinae is described based on male and female specimens from French Guiana. An updated key to the New World genera of Ectrichodiinae is provided.

A new species of Racelda Signoret, with taxonomical notes and a key to the males of the genus (Hemiptera, Reduviidae, Ectrichodiinae, Ectrichodiini)

“…The subfamily Ectrichodiinae in the New World includes 24 genera and more than 100 described species ( Gil-Santana and Baena 2009 ; Gil-Santana et al 2013 , 2015 , 2020 ; Gil-Santana 2014 , 2015 , 2019 , 2020a , 2020b ; Forthman and Weirauch 2017 ; Schuh and Weirauch 2020 ; Forthman and Gil-Santana 2021 ). A summary of the taxonomy of New World Ectrichodiinae was also provided by Gil-Santana et al (2015) .…”

“…Because of the lack of consensus of previous authors about the validity or recognition of some genera of Ectrichodiini ( Dougherty 1995 ; Carpintero and Maldonado 1996 ), there is a need of a taxonomic revision and a phylogenetic analysis of all these genera ( Gil-Santana et al 2015 , 2020 ). For instance, Pseudoracelda Carpintero, 1980 was considered to be a junior synonym of Racelda Signoret, 1863 by Dougherty (1995) but a valid genus by Carpintero and Maldonado (1996) , Forero (2004) , Gil-Santana et al (2013 , 2015 , 2020 ), and Forthman and Gil-Santana (2021) .…”

It is noteworthy that in this case, Dougherty (1995 : 175) justified her synonymization of these genera by stating that Pseudoracelda would have been erected by Carpintero (1980) for a female “whose character description fits well within the diversity seen in the sexual dimorphism of the genus Racelda .” She also stated that P. macrocephala Carpintero, 1980 “is retained as a species of Racelda because the unique specimen is unavailable for study.” In Ectrichodiinae , the sexual dimorphism ranges from slight (e.g., body size, development of the hemelytron, and eye and ocellar size) to extreme, where females exhibit brachyptery to aptery in both pairs of wings and major modifications in other parts of the body ( Forthman and Weirauch 2017 ).…”
