Stenodynerus lucidus
(Rohwer, 1917)
Stenodynerus lucidus is a small solitary in the Eumeninae. The was described by Rohwer in 1917 and is currently considered a synonym of Rhynchalastor lucidus by some taxonomic authorities, though it remains listed under Stenodynerus in other sources. Like other eumenine , it nests in pre-existing cavities and provisions its with paralyzed as food for its .

Identification
Stenodynerus lucidus is extremely difficult to distinguish from Parancistrocerus based on images of live specimens. Under microscopic examination, subtle morphological differences in structural features may allow separation, but these characters are not visible in field photographs. The Stenodynerus as a whole can be separated from some similar eumenines by features of the propodeum and structure, though specific characters for S. lucidus are not well documented in accessible literature.
Behavior
Females are known to use pre-existing tunnels such as old borings in dead wood or hollow twigs for nesting. They provision nest with paralyzed as food for larval offspring, a typical for in the Eumeninae.
