Type species: Erotylus quadripustulatus Fabricius (1801: 6) , by monotypy. Aulacochilus [sic] of Aulacocheilus Dejean 1836: 429 . Comments. There has been much confusion over the spelling of this genus ( Aulacochilus vs. Aulacocheilus ) and more recently over its authorship (Chevrolat vs. Dejean vs. Lacordaire), date of valid publication (1837 vs. 1842) ( Bousquet & Bouchard 2013: 6 ; Skelley 2020: 3 ), and type species. Aulacocheilus “ Lacordaire 1842: 245–246 ” [with the subsequently cited type species: Erotylus ( Aulacocheilus ) javanus Guérin-Méneville (1841: 155–156) ] was first emended to “ Aulacochilus ” by Redtenbacher (1858: 374) , which eventually became the spelling in prevailing use ( Chûjô & Chûjô 1989: 75–76 ). An immediately notable problem is that Guérin-Méneville’s use has priority over Lacordaire’s. In their catalog, Chûjô & Chûjô (1989: 76) referenced Dejean’s (1837) catalog (a reprinting of previous versions, see Bousquet & Bouchard 2013 ) by stating “ Aulacochilus (Chevrolat) Dejean, Cat. Col. ed. 3, 1837, p. 453 (nom. nud.!)”. However, there is an earlier use of the name by Dejean (1836: 429) . Bousquet & Bouchard (2013: 98) recognized that E . quadripustulatus Fabricius (1801) was an available species at the time it was listed under Aulacocheilus Dejean, 1836 . Thus, the name and original spelling of Aulacocheilus Dejean, 1836 with a type species by monotypy is available by indication ( ICZN 1999 : Article 12.2.5) and has priority over other spellings, attributions, and type designations.
