Listrochelus reinhardi
(Saylor, 1940)
Listrochelus reinhardi is a of scarab beetle described by Saylor in 1940. It belongs to the Listrochelus within the tribe Rhizotrogini, a group commonly known as May beetles or June beetles. The species is known from limited observations in Texas, USA. As with other members of Rhizotrogini, it is presumed to have subterranean larval stages and patterns typical of the group, though specific biological details remain poorly documented.

Identification
Identification of Listrochelus reinhardi requires examination of male genitalia and other subtle morphological characters used to distinguish within Listrochelus. The is characterized by features typical of Rhizotrogini, including with 9-10 segments and specific arrangements of tarsal claws. Distinguishing L. reinhardi from such as L. substriatus and L. limitatus depends on fine differences in aedeagal structure and pronotal sculpturing. No field identification characters have been published for this species.
Distribution
Known from Texas, USA. GBIF records indicate occurrence in the Nearctic region with specific locality data from Texas. The ' full range within North America remains poorly documented due to limited collection and identification effort.

Taxonomic history
Originally described by Saylor in 1940. The Listrochelus was historically treated as a subgenus of Phyllophaga but has been elevated to generic status in modern classifications. The epithet 'reinhardi' presumably honors an individual, though the etymology was not explicitly stated in the original description.
