Genus Liacos Guérin- Méneville, 1838

Scolia (Liacos) Guérin-Méneville, 1838: 246 (type species Scolia (Liacos) dimidiata Guérin-Méneville, 1838 , by monotypy [= Liacos analis ( Fabricius, 1804) ]).

Liacos (Triliacos) de Saussure & Sichel, 1864: 33 (type species Scolia analis Fabricius, 1804 , by effective original designation [see below]).

Tetrascolia Ashmead, 1903: 8 (type species Campsomeris urvillii Lepeletier, 1845 , by original designation [= Liacos analis ( Fabricius, 1804) ].

Notes

De Saussure & Sichel (1864) established Triliacos as a subgenus of Liacos including three species, without explicitly citing a type species. However, they did note that Triliacos represented “ Liacos proprie dicta” and included the type species of Liacos therein (as a synonym of L. analis ). Triliacos may therefore be regarded as a nomen novum for Liacos , meaning that it automatically has the same type species (ICZN Art. 67.8). Betrem (1928) thought a type species had not been established for Triliacos but also designated Scolia dimidiata . Argaman’s (1996) designation of Scolia erythrosoma Burmeister, 1854 as type species of Triliacos seems unwarranted.
