On your first picture it seems clearly to be 12 segments. In fact, there is always a confusion between the two species. Taking into account the key (not very clear) given by Fairmaire for the subgenus Lophosternus, angulicolis and dentipes are characterised having 12 articles with a third segment shorter for dentipes. After an accurate examination of several specimens of the two species, many of them have the last antennal segments (11/12) partially merged and this leads to a confusion. In addition, there are some slight variations in the lenght of the third antennal joint. That explain why it's not very easy to differentiate these species reported from the same area.
I have an ex. male of dentipes from Laos with clearly 12 free segments. |

Dorysthenes (Lophosternus) dentipes (Fairmaire, 1902) for the full name. |

I agree with D. dentipes (Fairmaire, 1902). |
