Euceratocerus parvus
This record describes Euceratocerus parvus (species). Recorded family: Ptinidae. Recorded order: Coleoptera.
Identification and Appearance
This species differs from the other 2 species in the genus ( hornii LeC. and gibbifrons White) in the smaller size and the more strongly pectinate male antenna. It is 2.9 to 3.4 mm long; the other two species range from 3.2 to 5.9 mm long. The ramus of the 4th antennal segment of the male of parvus is about 3 times as long as the segment, whereas the ramus of the 4th antennal segment (male) of both hornii (fig. 2) and gibbifrons (fig. 3) is a little longer than the segment.

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Euceratocerus parvus. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
