Definition
Lucaina marginata is a species of net‑winged beetle belonging to the family Lycidae.
Overview
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Coleoptera
- Family: Lycidae
- Genus: Lucaina
- Species: L. marginata
The species is part of the genus Lucaina, which comprises a small group of Lycidae known for their soft, reticulate elytra and often bright coloration that serves as a warning to predators. Information on the precise geographic range of L. marginata is limited in readily accessible scientific literature; it is presumed to occur in North America, as many Lucaina species are recorded from that region. Accurate information is not confirmed regarding its exact distribution, habitat preferences, and abundance.
Etymology / Origin
The specific epithet marginata derives from the Latin word marginatus, meaning “bordered” or “having a margin.” This name likely references a distinctive marginal coloration or pattern on the beetle’s elytra observed by the describer.
Characteristics
Members of the family Lycidae typically exhibit the following traits, which are expected to be present in L. marginata:
- Body form: Elongated and moderately flattened; adults range from 5 to 15 mm in length in related species.
- Elytra: Soft, loosely sclerotized, with a network‑like (reticulate) surface texture; often brightly colored (e.g., orange, red, or yellow) with contrasting margins.
- Antennae: Filiform to slightly serrate, usually 11 segments.
- Pronotum: May display a distinct lateral margin, potentially the feature referenced by the epithet marginata.
Specific morphological details (e.g., exact coloration, size measurements, sexual dimorphism) for L. marginata are not well documented in publicly available taxonomic keys. Accurate information is not confirmed for these species‑level traits.

Note: While Lucaina marginata is listed in several entomological catalogs, comprehensive peer‑reviewed descriptions are scarce; therefore, details provided here reflect general characteristics of the genus and family, with explicit acknowledgment of gaps in species‑specific data.
