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 supertribe Faronitae consists of 29 genera worldwide, and 13 genera in Australia and New Zealand. During examine 36 specimens from the private collection of Donald S. Chandler (Durham, New Hampshire, USA) and the Field Museum of Natural History (Chicago, Illinois, USA), we recognized three species. They does not share diagnostic characters with any known faronite genus. Here we describe new genus and three new species from Western Australia. Members of this new genus can be distinguished by the following combination characters: rostrum with distinct shallow and narrow frontal sulcus, apically sharp and narrow median lobe of male genitalia, and twice longer abdominal segment VI than V.

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.

개미사돈아과는 반날개과에서 두 번째로 큰 분류군이지만 다른 아과에 비해 연구가 가장 미흡한 분류군 중 하나이다. 개미사돈아과 내 다른 모든 아과의 자매군인 Faronitae상족은 비교적 작은 상족이며 최근 뉴질랜드 지역에서 종 수준의 포괄적인 재검토가 이루어졌다. 이를 바탕으로 Faronitae상족의 12속을 좀 더 쉽고 빠르게 동정하기 위하여 이미지를 활용한 interactive 분류키를 작성하였다. 분류키는 Lucid 3.3 builder를 사용하여 제작하였으며 총 36개의 형질과 134개의 형질상태를 사용하여 작성되었다. 이 프로그램은 현재 세계적으로 다양한 분야에서 사용되고 있는 식별키 프로그램이며, 제작 후 배포에도 용이하여 다른 연구자들에게도 정보를 제공할 수 있다. 이번 연구에서 포함된 속은 현재 뉴질랜드에 알려진 모든 속을 포함한다. 본 연구를 통하여 Faronitae상족에 대한 정보들을 제공하고, 웹 기반의 다양한 활용이 기대된다.
