Notes on the genera SuphisellusCrotch, 1873 and SuphisellusZimmermann, 1919, a cocktail of encrypted Suphiselloidesgenera (Coleoptera: Noteridae: Noterinae: Noterini)

Keywords: aquatic coleopteran, Genus Group, Nearctic, Neotropics, Suphisellus, Taxonomy

Abstract

The genus Suphisellusharbors genetically divergent taxa due to poor characterization and lack of comparison with the type species, S. bicolorCrotch, 1873. These differences are manifested in the genitalia and other morphological characters of all species considered to belong to the genus. However, they all share one common character state (the pseudo-triangular proventral process) and two additional ones (a cleft of the fourth maxillary palpomere and a lateral fold of the pronotum). The latter two are not found in all species and, when present, show great variability, indicating the presence of different generic taxa. Currently, 51 species of Suphisellusare recorded, but not all have the genital terminalia and their genitalia studied, especially the genitalia of the female. The genus itself represents a mixture or assemblage of Neotropical and Nearctic generic taxa encrypted. This situation, together with the morphological variations of groups of taxa that have been grouped under common characters, creating new genera, suggests the creation of a "Suphisellusor Suphiselloidesgenus group". Key is constructed to separate the Suphiselloidesgenera and a map with the geographic distribution in Venezuela.
