Megalodacne is a genusoffungivorous beetles in the family Erotylidae.[1]

Description

[edit]

Adult beetles of the genus Megalodacne range in size from 9 to 22 millimetres (0.35 to 0.87 in), making them among the larger members of the family.[2][3]

Distinguishing characteristics of the genus along with other members of the subfamily Megalodacninae include large eyes and a lack of depressions in the club joint of the antennae. The first three tarsomeres are also cylindrical and of similar shape and size, while the fourth is significantly shorter.[4]

Species of the genus Megalodacne closely resemble members of the genera Episcapha and Episcaphula (some members of which were formerly classified under Megalodacne).[5][6] They also often look superficially similar to several other beetles since the patterns of the markings of yellow, orange, or red on the elytra (called fascia) of Megalodacne are shared by many other beetle species.[2]

An example of which is the sap beetle (Nitidulidae) genus Glischrochilus.[7] Their native ranges sometimes overlap as well, making it easy to confuse the two (as with Megalodacne fasciata, Megalodacne heros, and the nitulidid Glischrochilus fasciatus from eastern North America). The best way to tell them apart is by size, as sap beetles are generally small, ranging from 2 to 12 mm (0.08 to 0.47 in) in length. Glischrochilus reaches a maximum length of only 12 mm (0.47 in).[8] Megalodacne on the other hand are large beetles ranging from 9 to 22 mm (0.35 to 0.87 in).[7][9] The elytra of the sap beetles which most resemble Megalodacne also do not cover the whole abdomen and leave the last abdominal segment(s) exposed.[9] The elytra of Megalodacne, on the other hand, completely cover the abdomen.[10]

Ecology

[edit]

Megalodacne species feed on harder bracket fungi than smaller members of the family.[2] The fungi eaten include Ganoderma[2] and Fomes species.[11]

Some tropical nocturnal species of Megalodacne are attracted to light.[4]

Life cycle

[edit]

Megalodacne deposit eggs on the fungi on which they feed. Upon hatching, the larvae, like adults, also feed on the fruiting bodiesofbracket fungi by burrowing into it.[12][13][14]

There are two kinds of larvae of Megalodacne depending on the species. In some species, the larvae are elongated and feed on fungi by drilling holes inside of it. In others, the larvae feed alongside adults by gnawing out shallow depressions on the fruiting bodies of fungi. The latter larvae are sluggish, heavily sclerotized, and somewhat flattened.[4] The larval stage takes about 2 to 3 months from egg to pupation. It is not uncommon to see adults feeding along with larvae.[15][16]

Taxonomy and systematics

[edit]

Megalodacne was first described by George Robert Crotch in 1873.[17] The type speciesisMegalodacne fasciata.[5] The genus Megalodacne is classified in the subfamily Megalodacninae, alongside the genera Episcapha and Episcaphula.[18]
