description: Subgenus Omalus s. str.
auratus group
Omalus (Omalus) auratus (Linnaeus, 1758)
= O. incertus Haupt, 1957
= O. auratus anthracinus (du Buysson, 1892)
= O. contrarius (Mader, 1939) [invalid name]
= O. auratus cupratus (Mocsáry, 1889)
= O. curtiventris (Tournier, 1879)
= O. auratus indigoteus (du Buysson, 1892)
= O. auratus maculatus (du Buysson, 1892)
= O. minimus (Dufour & Perris, 1840)
= O. obscurus (Tournier, 1889)
= O. testaceicornis (du Buysson, 1892)
= Omalus auratus viridiventris (Mocsáry, 1890)
Omalus auratus nigridorsus (Tsuneki, 1953)
Omalus triangulifer Abeille de Perrin, 1877
Omalus tshingiz (Semenov-Tian-Shanskij in Semenov-Tian-Shanskij & Nikol’skaya, 1954)
Omalus abdominalis (du Buysson, 1887)
Omalus violaceus (Scopoli, 1763)
= O. fuscipennis (Dahlbom, 1829)
= O. imperiale (Shuckard, 1837)
= O. nitidus Panzer, 1805
= O. similis (Mocsáry, 1889)
= O. violaceus virens (Mocsáry, 1889)
Omalus joannisi (du Buysson, 1909)
Omalus punctatus (Uchida, 1927)
Omalus grandis (Tsuneki, 1950)
Remarks. Currently, all species included in the Omalus auratus group sensu Linsenmaier are considered members of Pseudomalus, which was never adopted by Linsenmaier (1959a, b, 1968, 1987, 1994, 1997). The following species changed status or resulted belonging to a different genus:
Pseudomalus auratus cupratus Mocsáry, 1889 has been revalidated and raised to species rank by Rosa et al. (2017c); Elampus curtiventris Tournier, 1879 is actually a member of Elampus Spinola, 1806 (type examined).
punctulatus group
Omalus (Omalus) punctulatus Dahlbom, 1854
= O. parvulus Dahlbom, 1854
= O. socius (Mocsáry, 1889)
Omalus punctulatus tricolor Linsenmaier, 1999
Omalus perraudini Linsenmaier, 1968
Omalus bidentulus (Lepeletier, 1806)
= O. appendicinus Abeille de Perrin, 1878
= O. bidentulus styx Trautmann, 1926
= O. bidentulus uniformis (Trautmann, 1926)
= O. wesmaeli Chevrier, 1862)
= O. bidentulus bidentatus Eversmann, 1858
Omalus helveticus Linsenmaier, 1959a
Omalus hirtus (Semenov-Tian-Shanskij, 1932)
Omalus hirsutus (Semenov-Tian-Shanskij, 1932)
Omalus nikolskii (Semenov-Tian-Shanskij, 1932)
Omalus politus (du Buysson, 1887)
Omalus bogdanovii (Radoszkowski, 1877)
= O. bogdanovii cerberus (Trautmann, 1926)
= O. bogdanovi kerteszi (Trautmann, 1926)
= O. rudowi (du Buysson, 1887)
= O. bogdanovi unicolor (Trautmann, 1926)
Omalus biaccinctus (du Buysson, 1892)
= O. gasperinii (Mocsáry, 1889)
= O. biaccinctus muelleri (Trautmann, 1926)
Remarks. Currently, all species included in the punctulatus group sensu Linsenmaier are considered members of Philoctetes, excluding Omalus nikolskii (Semenov-Tian-Shanskij, 1932) (see Rosa et al. 2017a) and O. politus, which are truly Omalus sensu Kimsey & Bohart (1991).
Omalus bidentulus uniformis (Trautmann, 1926) could be a teratology of Pseudomalus auratus (Linnaeus, 1758) (type examined); Omalus bidentatus (Eversmann, 1858) was often considered as a valid taxon, nevertheless this name is an incorrect subsequent spelling of Omalus bidentulus (Lepeletier, 1806) (Rosa et al. 2015e); Omalus biaccinctus (du Buysson, 1892) has been considered as nomen protectum (Rosa et al. 2017c) because Linsenmaier (1951) and other researchers did not recognised the priority of the name O. gasperinii (Mocsáry, 1889), which was always incorrectly considered as a synonym of O. biaccinctus or its subspecies (see also Trautmann 1927 and Berland & Bernard 1938, the name gasperinii was also often misspelled as gasparinii).
aeneus group
Omalus (Omalus) aeneus (Fabricius, 1787)
= O. affinis (Wesmael, 1839)
= O. aeneus atratus (Mocsáry, 1887)

= O. chevrieri (Tournier, 1877)
