Figs 8–10

Dilychnia basalis Motschulsky, 1853: 30 .

Type material examined

Syntype FRENCH GUYANA • sex undetermined; “basalis ,, M. Par. Cayn.” // “Typ” // “ Dilychnia ,, basalis,, Motsch.” [E. Olivier handwriting] // “Guyana.”; ZIN.

Preservation status

Damaged, missing one antenna, terminalia, genitalia.

Remarks

Kazantsev & Nikitsky (2008) designated a syntype from ZMMU. Here we designate a second syntype. Motschulsky (1853: 30) described Dilychnia and only listed Dilychnia basalis in the publication, without providing a separate description for the species. A description for Dilychnia basalis was given by Motschulsky in a later publication (1854a: 7). Rendering D. basalis invalid would threaten the stability of this genus, since no other species were listed by the author. However, the article 12.2.6 of the International Code for Zoological Nomenclature (ICZN 1999) ensures combined descriptions for monotypic genera and their respective species described before 1961. Therefore, by the provisions of article 12.2.6, the publication date of Dilychnia basalis is 1853, and not 1854 as given in Vaz et al. (2020).

Current status

Synonym of Dilychnia guttula (Fabricius, 1801) .
