Remarks. Endang et al. (2002) described T. laticornutum from material collected in Central and East Java in 1991. It can be distinguished from other previously described species by the unusual form of the subgenital plate, with a hornshaped projection each side of the main lobe. The Sumatran specimens have wing markings and genitalic features similar to those of Javan individuals and, although the posterior lobe of the subgenital plate is relatively longer, we believe them to represent the same species.
