Bostrichoidea is the only superfamily of the suborder Bostrichiformia within the beetle suborder Polyphaga .

features

The assumed autapomorphy , which distinguishes the group from the closely related suborder Derodontiformia, is the spherical head and the obliquely downward-rearward (hypognathic) mouthparts of the larvae. In the species of the Bostrichiformia their head is more flattened and the mouthparts are protruding (prognath).

Autapomorphies of the Bostrichoidea without the bacon beetles (Dermestidae) are the "C" -shaped, maggot-like larvae, the end of the abdomen formed by an enlarged, rounded ninth segment, with the complete absence of the tenth segment. The autapomorphies that differentiate the Cucujiformia from both the Bostrichoidea and the Derodontoidea are the non-functional tracheal openings on the eighth abdominal segment , the ommatidia on the compound eyes with open rhabdomas and the "cucujuforme" (ring or sheath-shaped) aedeagus .

Distribution and way of life

The bacon beetles, borer beetles (Bostrichidae) and rodent beetles (Ptinidae) are distributed worldwide, only the Endecatomidae are limited in their distribution to the Holarctic .

Taxonomy and systematics

Although there was previously work that proposed a taxon that included the ancient group of Teredilia and the Dermestidae, Roy Crowson was the first to use the suborder Bostrichiformia, consisting of the superfamily Dermestoidea (Derodontidae, Nosodendridae, Jacobsoniidae and Dermestidae) and Bostrichoidea (Bostrichidae and Ptinidae) suggested in his work from 1955, 1959 and 1960. This concept was retained in the following work, although the relationships within this taxon were assumed to be very different.

Provided that the Bostrichoidea represent a sister group of the Cucujiformia , as suggested by Crowson in his work published in 1955, the establishment of the Derodontiformia for the families Derodontidae, Nosodendridae and Jacobsoniidae is mandatory for the monophyly of these groups.

The following families are therefore included in the Bostrichoidea:

Bacon beetle (Dermestidae) Latreille, 1804
Endecatomidae LeConte, 1861
Drill beetle (Bostrichidae) Latreille, 1802
Rodent beetle (Ptinidae) Latreille, 1802
