Neboiss, 1960
Species Guides
1Prolixocupes is a of reticulated beetles in the Cupedidae, suborder Archostemata. The genus contains two described with disjunct distributions: P. latreillei in central Chile and western Argentina, and P. lobiceps in western North America (Arizona, California, and Baja California, México). Archostemata is a small, relictual suborder of Coleoptera representing some of the most basal lineages.

Identification
Members of Prolixocupes can be distinguished from other Cupedidae by the combination of elongated body form and specific antennal structure characteristic of the . As with other Archostemata, possess visible notopleural and a transverse occipital ridge on the . -level identification requires examination of geographic origin and subtle morphological differences; P. latreillei and P. lobiceps are and do not overlap in range.

Conservation status
Both appear to have restricted ranges; P. latreillei has a relatively narrow latitudinal band in South America, while P. lobiceps occupies arid regions of southwestern North America. No formal conservation assessments were found in available sources.
Taxonomic history
established by Neboiss in 1960. The disjunct trans-Pacific distribution pattern is notable and shared with some other relictual groups, though the biogeographic history of this pattern in Prolixocupes has not been explicitly studied in available literature.
First Mexican records
P. lobiceps was first documented from México (Baja California Peninsula) in 2012, representing the first records of both suborder Archostemata and Cupedidae for the country.
