Gallery of Cryptophagidae

Cryptophagus Herbst, 1792

One of the three species-rich genera in Cryptophagidae. Primarily holarctic and in neighbouring areas of other zoogeographic regions. A few species adventive cosmopolitan.

Cryptophagus species have an anterior callosity and one tooth of each side of margin of the pronotum.


Micrambe Thomson, 1863

Rich in species and distributed in the Palaearctic (2007: 22 species) and Afrotropical Region (~ 80 species). Also known from islands like St. Helena, Reunion etc.

Micrambe species have an anterior callosity and, the margin of pronotum is denticulate.

Pteryngium Reitter, 1888

Two species with pronotum denticulate and without anterior callosity. Body flattened. The genus was revised (Esser 2017, in press)


Henotiderus Reitter, 1877

Similar to Henoticus Thomson, 1868 but it differs in the shape of the pronotum (denticulation, extra stria).


Atomaria Stephens, 1829

 The third species-rich genus in Cryptophagidae. As in Cryptophagus primarily holarctic with a few species in neighbouring areas of other zoogeographical regions. Two species are native afrotropical.


Antherophagus Dejean, 1821

The "giant" silken fungus beetles. A few species in the holarctic Region and neighbouring areas. They live obviously exclusive in nests of bumblebees. They are able to fly by themselves or on bumblebees (phoresy). Male Antherophagus differ from females in general shape and antennals.

Spaniophaenus Reitter, 1875

A small genus with four palaearctic species. They are characterized by its elongate shape of body and lacking any kind of denticulation at the margins of the pronotum. They live (all?) in nests of termite.

Spavius Motschulsky, 1844

A monotypical genus with one palaearctic species living in nests of Formica sp.

Resembling to Cryptophagus, but lacking the lateral tooth of pronotum. Very fine and dense punctured. Pubescence fine and inconspicuous.

Telmatophilus Heer, 1841

Six palaearctic and one nearctic species are known. They feed on pollen and seeds (larvae) of Typhaceae ans Cyperaceae.


Caenoscelis Thomson, 1863

Holarctic genus with a few species are known. Some interesting species lacking membranous wings and with a restricted distribution.

 Curelius Casey, 1900

Small genus of six tiny and oval beetles which are black, brown or yellowish. All species are described from the Palaearctic or Aethiopian Region. One species, C. japonicus, is cosmoplitan.
