Megatomini Explained

The Megatomini are a tribe of insects in the family Dermestidae.

The tribe was first classified by William Elford Leach in The Edinburgh Encyclopaedia in 1815.

Taxonomy

According to research in Zhou et al. (2022), only 3 major clades are recognized with support by both molecular and morphological data.

Megatomini classification by Zhou et al. (2022), with some genera excluded due to uncertain status (lack of research) and others revised given new research and further synonimization:

• Dermestidae
  • Megatominae
    • Megatomini
      • Orphinina
        • Caccoleptus
        • Curtophinus rev. nov.
        • Falsoorphinus rev. nov.
        • Labrocerus
        • Orphinus
        • Thaumaglossa
        • Zahradnikia
      • Megatomina
        • Globicornis (possible syn. Dearthrus)
        • Hirtomegatoma
        • Megatoma
        • Zhantievus
      • Trogodermina
        • Claviella
        • Cryptorhopalum
        • Eurhopalus rev. nov.^[1]
        • Phradonoma
        • Trogoderma
    • Anthrenini (Anthrenus and Dermeanthrenus)
    • Ctesiini (Ctesias)
  • other Dermestidae subfamilies

World Dermestidae catalogue (Jiří Háva, 2023) also separates subtribes Anthrenocerina and Cryptorhopalina. However genera of Anthrenocerina (Anthrenocerus and Myrmeanthrenus) are genetically closely related to species of Trogoderma and synonymous to neighboring, newly defined genus Eurhopalus.
