Treptoplatypus

Schedl, 1972

Treptoplatypus is a of (pinhole borers) in the , Platypodinae. The genus comprises more than 20 described , including the rare European species T. oxyurus, which forms obligate nutritional with cultivated within wood galleries. Members of this genus are wood-boring that colonize dead or dying trees, with some species showing specialized associations.

Habitat

Large dead trunks of coniferous trees in natural forests; concentrated in windthrow gaps. are usually absent in managed forests. At least one (T. oxyurus) is specialized on Abies alba.

Distribution

Europe (France, Spain, Corsica, Sardinia, southern Italy, Croatia, Greece, Slovakia, Germany), India, and possibly Turkey and Iran. Distribution varies by ; T. oxyurus is scarce in Central Europe.

Diet

Obligate nutritional with cultivated within galleries; fungi serve as the primary food source.

Host Associations

  • Abies alba - primary tree (T. oxyurus)large dead trunks in natural forests
  • Candida schatavii - fungal found in prothoracic mycangia
  • Magnusiomyces fungicola - fungal found in prothoracic mycangia
  • Wilhelmdebeerea oxyuri - most abundant mycangial novel described from T. oxyurus
  • Blastobotrys sasensis - low abundance yeast associateuncertain ecological role
  • Sugiyamaella casensis - low abundance yeast associateuncertain ecological role

Life Cycle

Develops exclusively in large dead trunks. For T. oxyurus: , , and gallery fragments observed in wood at advanced decay stage; probable observed July–August.

Behavior

Forms galleries in wood with layer for fungal . possess mycangia (fungal organs) located in the . Wood-boring pinhole borer .

Ecological Role

Contributes to wood decomposition through fungal . Facilitates entry of other organisms into wood resources. Part of subcortical fungal ; may delay wood decay through fungal cultivation.
