Description and sexual dimorphism
C. bassiformis displays clear wings, or areas of translucence, with a dark border around the forewing. Their wingspan in males is 17-20 mm, with females being 20-22 mm. Both males and females have a purplish-black thorax, and the abdomen the same but with yellow stripes. On females, the 3rd and 5th stripe will be thinner, while males will remain, for the most part, around the same width. Females will also have white segments on their antennae, while males will have all black or short tips of white. Female's tails will have a tuft of orange, while male's will be more flat and black.
Distribution
C. bassiformis is found in the eastern United States from New York to Florida; west to Wisconsin, Kansas, and Texas.

Why this record matters
“Carmenta bassiformis” is worth following because a concise public description often conceals a longer documentary argument. Here, Carmenta, bassiformis and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q2423129. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1856.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
