摘要：
A new species of medicinal leech, Macrobdella mimicus n. sp., is described from specimens collected in Maryland; this is the first description of a North American macrobdellid since 1975. Superficially, the new species resembles the well-known Macrobdella decora, as both species possess 4 accessory pores arranged symmetrically on the ventral surface, yet the new species is distinguished from M. decora in possessing 4-4 1/2 annuli (rather than 3 1/2) between the gonopores and 4 annuli (rather than 5 annuli) between the female gonopore and the first pair of accessory pores. Phylogenetic analyses, based on 2 mitochondrial and 2 nuclear loci for a set of closely related taxa, confirms the placement of the new species within the family Macrobdellidae and places it as the sister taxon to M. decora and M. diplotertia.
