This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

Only two extant species of Prolixocupes are known: Prolixocupes latreillei (Solier, 1849) from central Chile and western areas of Argentina close to the Chilean border between 25° and 35° southern latitude, and Prolixocupes lobiceps (Leconte, 1874) from western North America where it was found in a few localities in California and Arizona (USA).
The larvae of both species are unknown. Papp (1961) described an association of P. lobiceps with Plantanus racemosa Nutt. but beyond this nothing is known about the food sources and larval host plants.
Both species were originally described in the genus Cupes. Neboiss (1960) transferred them to his newly established genus Prolixocupes. Atkins (1963) identified Cupes boycei Papp, 1961 as a junior synonym of P. lobiceps.
Both species are of similar size, with P. lobiceps being a little bit smaller (c.10mm long & 3mm wide, P. latreillei is c. 12 mm long & 3 mm wide).
Characteristic features of the genus are the strong, long antennae, which are slightly serrate (more strongly in P. latreillei) and distinctly decrease in diameter from the basal to the distal antennomeres.
Both species also have the typical cupedine dorsal head protuberances, which are very large and bulbous. This feature is distinctly more conspicuous in P. lobiceps than in P. latreillei.
Discussion of Phylogenetic RelationshipsAccording to Hörnschemeyer (2009) Prolixocupes is the sister group to all other Cupedidae except Priacma and Paracupes.
