Taxonomy and species

Takagi (1965) originally divided the genus into seven species groups. According to Masunaga et al. (2005) and Masunaga & Saigusa (2010), the genus can be divided into two clades: one containing the rectus species group (including the type species), and the other containing all other species groups, for which the authors intended to propose a new genus. The latter clade they also consider to be the sister group of Thambemyia. rectus species group (= Conchopus sensu stricto): Conchopus acrosticalis (Parent, 1937) – Hawai‘i, Maui, Lāna‘i, Moloka‘i Conchopus borealis Takagi, 1965 – Japan, North America (introduced), Peru (introduced) Conchopus ciliatus Masunaga & Saigusa, 2010 – Hawai‘i, Maui, O‘ahu, Lisianski Conchopus crassinervis Masunaga & Saigusa, 2010 – Kaua‘i Conchopus menehune Masunaga & Saigusa, 2010 – Kaua‘i, Nihoa Conchopus minutus Masunaga & Saigusa, 2010 – Hawai‘i, Maui, Lāna‘i, Moloka‘i, O‘ahu, French Frigate Shoals Conchopus pacificus Masunaga & Saigusa, 2010 – Hawai‘i, O‘ahu, Kaua‘i, Wake Conchopus pudicus Takagi, 1965 – Japan Conchopus rectus Takagi, 1965 – Japan, China Conchopus sikokianus Takagi, 1965 – Japan Conchopus taivanensis Takagi, 1967 – Japan, Taiwan sinuatus species group: Conchopus corvus Takagi, 1965 Conchopus sinuatus Takagi, 1965 sigmiger species group: Conchopus saigusai Takagi, 1965 Conchopus sigmiger Takagi, 1965 Conchopus uvasima Takagi, 1965 convergens species group: Conchopus convergens Takagi, 1965 Conchopus poseidonius Takagi, 1965 Conchopus signatus Takagi, 1965 nodulatus species group: Conchopus nodulatus Takagi, 1965 Conchopus mammuthus Takagi, 1965 anomalopus species group: Conchopus anomalopus Takagi, 1965 abdominalis species group: Conchopus abdominalis Takagi, 1965 Other species: Conchopus shandongensis (Zhu, Yang & Masunaga, 2005)
