Biology and distribution
Described from New York USA (H. fieldsi), England (T. amabilis) and Czech Republic (T. semicaeca). Recorded from Honshu, Japan (Okajima, 2006) and New Zealand (Mound & Walker, 1986).
Distribution: Recorded widely across central and western Europe, also from Bulgaria, and also from North America, Japan and New Zealand. Mound & Walker (1986) gave reasons for suggesting that this species may have been distributed from New Zealand by 19th century shipping. H. semicaecus occurs on dead branches and under bark of dead trees, fungus-feeder (Okajima, 2006).
