Posted - 29/05/2011 : 18:43:07 Well: there are only two possibilities: T. politus Bates or T. elegans Dupont. T. politus has antennae black with the last antennomeres yellow, T. elegans has antennae ringed (typical form) or completely black-brown (other subspecies). Therefore, Trachyderes elegans elegans Dupont, 1836. |
