摘要: Two-jawed (duognathous) terrestrial leeches in the Haemadipsidae are major pests across their wide geographic range, represented by numerous endemic species Australia and many islands Indian Pacific Oceans. However, haemadipsid taxonomy, based largely on externally visible characters, remains conflict with phylogenetic relationships. We capitalize power of microcomputed tomography (μCT), allowing for first description an extant soft-bodied – Chtonobdella tanae sp. n. using this technology. Several fixation strategies invertebrates μCT scanning applications also evaluated. Expanding prior work, higher taxonomy duognathous haemadipsids was evaluated analyses DNA sequence data. Whereas monophyly supported, substantial remained respect to named genera. Consequently, genus revised include all leech previously distributed 31, mostly monotypic
