The subgenus ParabatesFörster, 1869 is one of 12 subgenera of the genus Netelia belonging to the subfamily Tryphoninae. Parabates is a small subgenus with only six species worldwide: three from the Palaearctic, two from the Nearctic and two from the Oriental regions (Yu et al., 2016). It was originally described as a genus by Förster (1869) based on Parabatus nigricarpus.

In South Korea, Lee and Cha (1996, 2000) reported N. (P.) fusca Konishi and N. (P.) ishiharai Uchida. In the present study, an additional, N. (P.) nigricarpus, is for the first time from South Korea. Diagnoses and photographs of the diagnostic characteristics of known species are provided.

Materials and Methods

The morphological terminology used in the present study follows that of Gauld (1991). Terminology for the male genitalia follows that of Snodgrass (1941). The genitalia were dissected following Konishi (2005). The heads and mesosoma were measured by the methods of Konishi (1985). The following indices (Gauld and Michell, 1981) were used:

Specimens were examined using a Canon EOS 450D digital camera attached to Helicon Remote (ver. 3.6.6w). Images were stacked using Helicon Focus 6®. Distributional data mainly follow that of Yu et al. (2016). Species descriptions and diagnoses are based on South Korean specimens.

All examined specimens have been deposited in the Yeungnam University (YNU), Gyeongsan, South Korea.
