Discussion. The records above apparently all refer to a single Martinique specimen, which we have not found. The identity of this specimen is unknown at this time, thus it is placed incertae sedis. In spite of three species names being involved, there is only a single record here.

We can trace the record to Leng and Mutchler (1914), but no voucher has been found. It may originate earlier, but we have been unable to find it. In 1957, Marcuzzi did not cite a specimen for his Martinique record of D. perforatus in his table. In 1962, he dropped the D. perforatus record for Martinique, rather moving it to D. hummelincki with a “?” In 1977, D. hummelincki was replaced with D. mulsanti , and the Martinique record retained. Lastly, in 1984, the Martinique record for D. perforatus was reinstated by Marcuzzi, apparently forgetting he moved it to D. hummelincki / mulsanti , which was also retained. Peck (2011b, 2016) listed it twice, under two names, without understanding the records.
