Deltaspis auromarginata var. cyanipes Bates, 1885: 322 .

Remarks. – ThisspecieswasdescribedfromMexico(SanCarlos).There are several places in Mexico named San Carlos, in many states. Selander & Vaurie (1962) did not report this locality. Monné (2023a) and Tavakilian & Chevillotte (2022) reported that the species was described based on a holotype. However, Bates (1885) stated about Deltaspis auromarginata Audinet-Serville, 1834 : “All the examples I have seen of this species belong to the var. D. cyanipes (Klug, MS.) , which, according to Lacordaire,is a variety of D. auromarginata .” Therefore,the species was described based on unknown number of syntypes.

Deltaspis cyanipes appears in Dejean (1835) as attributed to Klug. However, the name is a nomen nudum in Dejean (1835). We were unable to find a work by Jean Théodore Lacordaire in which he mentioned that D. cyanipes is a variety of D. auromarginata . Bates (1892), in the description of D. rufostigma var., discussed D. cyanipes , not D. auromarginata var. cyanipes : “ D. cyanipedi (Klug = auromarginata, Serv. ?);” “In the form and colour of the thorax this variety answers much better than D. cyanipes does to Serville’s description of D. auromarginata …;” and: “In D. cyanipes the thorax …” Chemsak & Linsley (1982), without explanation, listed D. cyanipes as a species different from D. auromarginata , a condition maintained until today.

Monné (2023a) reported this species from Mexico (Jalisco, Puebla, Mexico, Morelos, Sinaloa, Guerrero, and Veracruz). Eya (2019) did not report the Mexican states of Mexico (recorded by Toledo 2005) nor Sinaloa (recorded by Monné 2005). Apparently, the citation of the Mexican state of Guerrero appeared for the first time in Monné (2005). However, we do not know a work mentioning this state before the citation in this catalog, as well as the state of Sinaloa. Eya (2019) confirmed the presence of this species in the Mexican state of Guerrero but not in Sinaloa. We confirm the presence of D. cyanipes in Sinaloa.

Material examined

- MEXICO, Sinaloa: Potreillos , 1950 m, 1 ♂, VII.2021, local collector ( IMQC) ;

- Loberas, 1950 m, 1 ♀, local collector ( IMQC) .

With the revalidation of Prionus (Antennalia) and Prionus (Neopolyarthron) , and the description of the new species, the alternative of couplet “9” in Santos-Silva et al. (2016) needs to be modified as follows:

9 (8). Sides of metaventrite pubescent............................................................................... 9 ’ –– Metaventrite entirely glabrous........................................... 10 [P. (Antennalia) and P. ( Neopolyarthron )]

9 ’(9). In ventral view, distance between lower eye lobes slightly greater than maximum diameter of scape; wide central area of metaventrite almost glabrous. Mexico (Durango)....................................... Prionus (Prionus) hectori sp. nov.

–– In ventral view, distance between lower eye lobes greater than twice maximum diameter of scape; wide central area of metaventrite pubescent. Mexico (Durango, Zacatecas)............................. Prionus (Prionus) aztecus Casey, 1912
