Definition
Tomoxia spinifer is the scientific name of a species of beetle belonging to the genus Tomoxia within the family Mordellidae, commonly known as tumbling flower beetles.
Overview
The species is listed in taxonomic catalogs of Mordellidae, though detailed information on its morphology, distribution, and ecology is limited in widely accessible scientific literature. As a member of Tomoxia, it is presumed to share the general habits of tumbling flower beetles, which are small, wedge‑shaped insects that are frequently found on flowers and are known for their characteristic leaping behavior when disturbed.
Etymology / Origin
The generic name Tomoxia derives from Greek roots: “tomos” meaning “cut” or “section” and “oxys” meaning “sharp,” possibly referencing the beetle’s pointed abdomen. The specific epithet spinifer is Latin for “bearing spines” (from spina “thorn, spine” and -fer “bearing, carrying”). The name therefore suggests a species with notable spine‑like structures, likely on the elytra or posterior abdomen.
Characteristics

Taxonomy:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Coleoptera
- Family: Mordellidae
- Genus: Tomoxia
- Species: T. spinifer
-
Morphology: While specific measurements for T. spinifer are not widely published, Tomoxia species are generally small (3–6 mm in length), with a convex, tapering abdomen that terminates in a pointed pygidium. The epithet “spinifer” indicates the presence of spines or pronounced tubercles, likely on the elytra or pronotum.

Habitat and Behavior: As with other Mordellidae, members of Tomoxia are typically associated with flowering plants where adults feed on pollen and nectar. Their larvae develop in decaying wood or plant stems. Precise habitat preferences for T. spinifer remain undocumented.
-
Distribution: Accurate information on the geographical range of T. spinifer is not confirmed. Species of Tomoxia are known from various regions, including parts of North America, Europe, and Asia, but the specific locality of T. spinifer requires verification from taxonomic literature or museum records.
