Six new species are described that are members of the New Zealand endemic genus Adalmus Reitter (Staphylinidae: Pselaphinae: Euplectitae: Trichonychini: Panaphantina): A. bullerensis sp. nov., A. kanierensis sp. nov., A. karekarensis sp. nov., A. mangamukaensis sp. nov., A. puberilumbus sp. nov., and A. serrilumbus sp. nov. In addition, Dalmisus Sharp is placed as a junior synonym of Adalmus (gen. syn.) and the species Dalmisus batrisodes Sharp, 1886, Plectomorphus longiceps Broun, 1913 and P. longipes Broun, 1912 are placed as junior synonyms of A. velutinus Reitter, 1885 spp. syn. Also, P. rugiceps Broun, 1921 is transferred to the genus Adalmus, comb. nov. Adalmus now holds eight species.

Harpiphorus, a monotypic genus of subfamily Allantinae (Symphyta: Tenthredinidae), was established based on Tenthredo (Emphytus) lepida Klug. The genus is close to Hemibeleses Takeuchi but can be easily distinguished by the following characteristics: the cell 1M in fore wing with a distinct petiole dorsally and cell M in hind wing closed. Harpiphorus is widely distributed in Europe, but has not yet been found in outside the continent. The larva of this genus is phytophagous attacking the oak species (Quercus trojana Webb and Q. robur L.). As a result of the present study, the genus Harpiphorus is reported based on H. lepidus for the first time from South Korea and the Eastern Palaearctic region. A diagnosis, figures of morphological features are provided.
