Bottchrus Jedlièka, 1935


Subgenus Bottchrus Jedlièka, 1935 

Trichotichnus (Bottchrus) birmanicus ( Bates, 1892) 

Andrewes (1926), Schauberger (1934), Lee & Winney (1981) and Hua (2002) list this species as occurring in Hong Kong. Kataev et al. (2003) does not list this species as occurring in Hong Kong under the heading for this species, but under the list of synonyms of the genus Siopelus  , indicating that it is found in Hong Kong. Interestingly Schauberger (1934) lists a Hong Kong specimen collected by M. Cameron. Note, this species is placed in the subgenus Bottchrus  on advice from David W.,Wrase (pers. comm.) " Bellogenus and Pseudotrichotichnus  are synonyms to Bottchrus  ".

There is possibly another species of this subgenus in Hong Kong. Specimens key to T. birmanicus ( Bates, 1892)  using Kirschenhofer (1992), but vary slightly from his illustration mainly in the tip of the male genitalia slightly more pointed apically. However David W. Wrase (pers. comm.) noted "This [new] species belongs to Bottchrus  but surely not to birmanicus  due to the strong puncturation of pronotum and internal sac structure of median lobe different from birmanicus  .".

Can be attracted to light, especially abundant in the late autumn when many wet areas dry up. It is fully winged.
