Erepsocassis rubella
(Boheman, 1862)
Erepsocassis rubella is a of tortoise beetle ( Chrysomelidae, Cassidinae) described by Boheman in 1862. As a member of the Cassidini tribe, it possesses the characteristic domed body shape that provides protection by allowing the to clamp tightly against leaf surfaces. The species is poorly documented in scientific literature, with minimal published information on its and . It belongs to a containing few described species, most of which are associated with Neotropical and Nearctic regions.

Identification
Identification to level requires examination of genitalic characters and comparison with , as external morphological features among Erepsocassis species are subtle. The is distinguished from related cassidine genera by specific configurations of the prosternal process and elytral punctation patterns. Specimens should be compared against Boheman's original description (1862) and subsequent taxonomic revisions of Neotropical Cassidini.
Distribution
Recorded from North America; precise range boundaries are undocumented. The Erepsocassis has broader distribution in the Neotropical region, suggesting this may occur in southern portions of North America extending into Central America.
Behavior
Has been observed to display the characteristic defensive of tortoise beetles: when disturbed, clamping the body tightly against the leaf surface to present only the smooth, convex to potential .

Taxonomic note
The Erepsocassis was established by Spaeth in 1913 and contains relatively few described . The group has received limited modern taxonomic attention, and species boundaries may require revision based on expanded specimen series and molecular data.
Data deficiency
With only one observation documented in iNaturalist and minimal literature records, this represents a significant gap in coleopteran biodiversity knowledge. Basic biological parameters including plants, complete distribution, and seasonal activity patterns remain unknown.
