Elateriformia is an infraorder of polyphagan beetles. The two largest families in this group are buprestids, of which there are around 15,000 described species, and click beetles, of which there are around 10,000 described species.

The infraorder consists of five superfamilies :

Schnellkaefer auf Ast
Agrypnus murinus, a click beetle
Scientific classification
Kingdom: Animalia
Phylum: Arthropoda

Buprestoidea is a superfamily of beetles.It contains two families:

Buprestidae Leach 1815, the jewel beetles or metallic wood-boring beetles.

Schizopodidae LeConte 1861


Byrrhidae, the pill beetles, is a family of beetles in the superfamily Byrrhoidea. These beetles are common in the forests of the Northern Hemisphere. They feed mainly on moss. Populations increase after wildfires.There are about 450 species in this family.Genera include:

















The superfamily Byrrhoidea includes a number of beetle families, most of which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, the majority of the remaining Polyphagan beetles which are aquatic are in this superfamily. These families were traditionally grouped as a separate superfamily, the Dryopoidea, which is no longer recognized. The vast majority of species are small (<1 cm), and predominantly dull brown or black.


Callirhipidae is a family of beetles in the superfamily Byrrhoidea. It was described by Emden in 1924.


Chelonariidae or turtle beetles is a family of beetles in the superfamily Byrrhoidea. It was described by Blanchard in 1845.


Cneoglossidae is a family of beetles, in the large suborder Polyphaga.

It contains nine species in a single genus:

Genus Cneoglossa Guérin-Méneville, 1843

Cneoglossa brevis Champion, 1897

Cneoglossa collaris Guérin-Méneville, 1849

Cneoglossa elongata Pic, 1916

Cneoglossa longipennis (Pic, 1915)

Cneoglossa peruviana Pic, 1916

Cneoglossa rufifrons Pic, 1916

Cneoglossa testacericollis Pic, 1916


Dascilloidea is a superfamily of polyphagan beetles, comprising two families: Dascillidae (soft bodied plant beetles) and Rhipiceridae (cicada beetle and cicada parasite beetles).


Decliniidae is a family of beetles in the large suborder Polyphaga. It contains the single genus Declinia with two species,

Declinia relicta Nikitsky, Lawrence, Kirejtshuk, Gratshev 1994

and D. versicolor Sakai, Sato 1996, found in far eastern Russia and Japan.


The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives.

Certain clusters of families within the superfamily are more strongly related to one another; for example, the Elateridae have close ties to the Cerophytidae, Eucnemidae, and Throscidae, and some of these beetles can also "click".

Likewise, the Lampyridae are very closely related to the Phengodidae (which includes Telegeusidae), and the doubtfully distinct Rhagophthalmidae; members of these families are also bioluminescent, at least as larvae. This group of families also includes many taxa whose females are larviform, though this is also known from a few other families in the superfamily.

The validity and relationships of some families, such as Podabrocephalidae, Rhagophthalmidae, and Rhinorhipidae, are not fully resolved.


Elmidae, commonly known as riffle beetles, is a family of beetles in the superfamily Byrrhoidea described by John Curtis in 1830. There are more than 150 genera and 1,500 described species in Elmidae.


Eucinetidae is a family of beetles, notable for their large coxal plates that cover much of the first ventrite of the abdomen, sometimes called plate-thigh beetles. The family is small for beetles, with about 50 species in 11 genera, but are found worldwide.

Adults are generally elliptical in shape, ranging from 0.8 to 4.0 mm in length, and black or brown in color. The head is small and bent underneath.

Eucinetids live in detritus or in fungus-covered tree bark, where both adults and larvae eat various sorts of fungi.


The Eucnemidae, false click beetles, are a family of polyphagan beetles including about 1700 species distributed worldwide.


Heterelmis is a genus of beetles in the riffle beetle family Elmidae.Species include:

Heterelmis comalensis

Heterelmis glabra

Heterelmis obesa

Heterelmis obscura

Heterelmis stephani

Heterelmis tarsalis

Heterelmis vulnerata

Lara (beetle)

Lara is a genus of Nearctic beetles in the family Elmidae.Name Lara was also applied to a genus of orthopterans by Otte and Alexander in 1983 (now Musgravia Otte, 1994), and to a genus of harvestmen by González-Sponga in 1987 (now Venezuelana Özdikmen, 2008).


Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species so far discovered.

Key characteristics of Polyphaga are that the hind coxa (base of the leg), does not divide the first and second abdominal/ventral plates which are known as sternites. Also, the notopleural suture (found under the pronotal shield) is not present.


The Rhinorhipidae are a family of beetles, in the large suborder Polyphaga. It contains the single genus Rhinorhipus with a single species Rhinorhipus tamborinensis


Scirtidae is a family of beetles (Coleoptera). These beetles are commonly referred to as marsh beetles, as the larvae are typically associated with stagnant water, but can be found in flowing water. Adults prefer decomposing plant material near the water's edge. More than an estimated 600 species are known worldwide, distributed among at least 60 genera.


Scirtoidea is a superfamily of beetles in the suborder Polyphaga.

There are four families in this small superfamily:
