Subgenus Omalus s. str.

= 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 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)

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 )

Omalus hirtus ( Semenov-Tian-Shanskij, 1932)

Omalus hirsutus ( Semenov-Tian-Shanskij, 1932)

= O. rudowi ( du Buysson, 1887)

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).
