Ecology

Species of the genus Colilodion are presumed to be myrmecophiles due to the presence of trichomes retaining ant pheromones.[1][2]

Systematics

The exact systematic placement of the genus remains uncertain; it is the only member of the Colilodionini tribe, sharing certain characteristics with Clavigeritae, where it was originally placed by Claude Besuchet in 1991,[1] and others that resemble the Pselaphitae.[3][4] Eight species have been described:[4]

  • Colilodion concinnus Besuchet, 1991
  • Colilodion incredibilis Besuchet, 1991
  • Colilodion inopinatus Besuchet, 1991
  • Colilodion mirus Besuchet, 1991
  • Colilodion schulzi Yin & Cuccodoro, 2016
  • Colilodion tetramerus Löbl, 1998
  • Colilodion thienmu Nomura & Sugaya, 2007
  • Colilodion wuesti Löbl, 1994
