Distribution. Taiwan (Fig. 19).

Remarks. Ma (1995) reported that Epitrichius elegans is distributed in the Chinese insular province Hainan, southern China. However, we did not find any other specimens and/or collecting records of the species in Hainan. Because E. elegans is a splendid trichiine that can be easily distinguished from other species in the genus, we therefore treat the record from the island Hainan as doubtful. Adults of E. elegan s are widely distributed throughout the Central Mountain Ranges of Taiwan and the adjacent mountains ranging from 600– 2000 m in elevation. The temporal distribution of T. elegans ranges from the end of May to early September with most found visiting flowers in the forest canopy.
