Idiotarsus errans
Idiotarsus errans is a of leafhopper in the Cicadellidae, tribe Cicadellini. It belongs to a of relatively small, slender leafhoppers distributed primarily in the Neotropical region. The species was described by the German entomologist Hermann Haupt in 1927 based on specimens from South America. Like other members of its tribe, it likely inhabits vegetation in forested or semi-forested where it feeds on plant phloem.

Identification
Identification to level requires examination of male genitalia, particularly the and associated structures, which provide the primary diagnostic characters for species in Idiotarsus. The can be distinguished from related leafhopper genera by features of the and pronotum, including the shape of the vertex and the arrangement of setae. Specimens should be compared with the original description by Haupt (1927) and subsequent taxonomic revisions of Neotropical Cicadellini.
Habitat
Forest and semi-forested environments in the Neotropical region, likely associated with understory vegetation and shrubs. Specific plant associations have not been documented.
Distribution
Recorded from South America; the type locality and precise range are poorly documented in readily accessible sources. The Idiotarsus has broader distribution in Central and South America.
Similar Taxa
- Other Idiotarsus speciesCongeneric share similar body form and general appearance, requiring genital dissection for reliable separation.
- Cicadellini genera (e.g., Cicadella, Balclutha)Members of the same tribe share overall leafhopper and wing posture; distinguished by subtle differences in shape, pronotal structure, and male genitalia.

Taxonomic History
Described by Hermann Haupt in 1927. The Idiotarsus was established by Berg in 1879 and currently contains multiple distributed in the Neotropics. The specific epithet 'errans' (Latin for 'wandering' or 'roaming') may allude to or collection circumstances, though this interpretation is speculative.
Literature Access
Original description and subsequent taxonomic treatments are primarily in German or Portuguese taxonomic literature not widely digitized. Modern revisionary work on Neotropical Cicadellini is limited, contributing to sparse accessible information for this .
