(PNH, holo, destroyed; iso: AMES*, K, all cited by Pedersen, 1997: 66; an unnumbered Copeland specimen,
US barcode # 00344424, dated April 1904 from Mt Apo is possibly an isotype). Mindanao: Davao del Sur

throughout the year (except in Aug). According to Pedersen (1997: 68), records from Taiwan
by Ying is possibly due to confounding with D. uncatum which is very well-known there.
