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.
The subfamily Pselaphinae is one of the largest groups in the family Staphylinidae. Pselaphine beetles consists of 6 supertribes. The supertribe Faronitae consists of 30 genera worldwide, with 14 genera in Australia and New Zealand. While examining faronite specimens, we separated 366 specimens that did not belong to any known faronite genera. Species of this genus can be separated from other faronite genera by the foveal system, features of the aedeagus, and collection localities which are only collected in the southern part of Australia. Through this study, we describe seven new species and three new combinations that previously belonged to the genus Sagola.
The Australian genus Logasa Chandler was described in 2001 based on Logasa novaeangila Chandler 2001. Other two species, Logasa tricolor (Oke 1928) and Logasa ventralis (Oke 1928) were originally described as the genus Sagola, and transferred to Logasa by Chandler. During revisionary study using 140 museum specimens, additional three new species was recognized. After type examination of L. tricolor and L. ventralis, we found that they have different diagnostic characters for generic level such as foveal system and male genitalia. However, their diagnostic characters are not included any known faronite genus. Australian faronite fauna has numerous undescribed species. They will revise with other undescribed species for a following study.
