6 spp. in our area, ~40 spp. total(1)
Identification
Key to spp. in(2)
Only the rare southeastern T. lividus (LeConte) lacks the complex scale pattern, erect tufts, and bottle-brush tibiae. (Barry Valentine, pers.comm.)
Range
e. US (NY-IL) to Argentina, including endemics in the West Indies, but none in the Galapagos; in our area, 3 spp. in mostly se. US, 2 in so. TX, and one in sw. US (so. NM & AZ) (Barry Valentine, pers.comm.)
Habitat
One of many genera without a definite fungus connection. All biological data involve dead wood, but there are no mentions of fungi. We have collected two eastern species on dead oak branches and on a dead gumbo limbo tree trunk, neither with obvious fungi. Most specimens are taken at light. (Barry Valentine, pers.comm.)
