Scaphomorphus erysimi
(Fall, 1901)
Scaphomorphus erysimi is a of in the , Lixinae. The species was originally described by Fall in 1901 under the Cleonus and later transferred to Scaphomorphus. It is currently recognized as a synonym of Cleonus erysimi in some taxonomic databases, though iNaturalist maintains it under Scaphomorphus. Very little is known about this species' biology or distribution beyond basic taxonomic records.

Taxonomic instability
This exemplifies taxonomic uncertainty in the Lixinae. GBIF treats Scaphomorphus erysimi as a synonym of Cleonus erysimi, while iNaturalist maintains it as a valid species under Scaphomorphus. This discrepancy reflects ongoing debate about generic limits in the Cleonini tribe. The original description by Fall (1901) requires examination to clarify whether the species is best placed in Scaphomorphus or Cleonus.
Data deficiency
With only 2 observations in iNaturalist and minimal literature records, this is among the most poorly known . No information is available on plants, seasonal activity, or geographic range beyond the locality (which is not specified in the provided sources). Field work targeting this species would require locating the and original description to determine where and when it was collected.
