Peltogaster sp. 2 ( Fig. 5H )

Material examined: On Areopaguristes nigroapiculus : 1 Ind., Pohang, fishing net, 7 Sep. 2001, EVOSYS 260510#008, host: male, SL 7.0 mm.

Host: A. japonicus ( Diogenidae ).

Distribution: Korea.

Remarks: We reported A. nigroapiculus as a new host of peltogastrid species. In addition, the morphological characteristics of the externa of the specimens, such as a single oval shape of the whole externa, slightly elevated terminal-located mantle aperture with slit-shaped opening, and present of a chitinous shield agreed with the description of Peltogaster sp. parasite on A. japonicus reported by Yoshida et al. (2014). Because we could not obtain sequencing data on the specimens, additional data are necessary to identify this species.
