Type material: Holotype male from MEXICO, Jalisco: Mixtlan , 1,842 m, 22.VII.2012, G. Nogueira leg. ( CNIN) . Paratype female same data as holotype ( DHCO).

Etymology: This species is named after Guillermo Nogueira (Zapopan, Jalisco, Mexico) who collected the holotype.

Remarks: By the pronotal punctation somewhat abundant and elytra not distinctly narrowed toward apex, Aegomorphus nogueirai sp. nov., is similar to A. antonkozlovi Santos-Silva, Nascimento & Silva-Junior, 2020 , A. arizonicus Linsley & Chemsak, 1984 , A. chamelae Chemsak & Giesbert, 1986 , A. galapagoensis williamsi (Linsley & Chemsak, 1966) , A. galapagoensis galapagoensis (Linell, 1898) , A. galapagoensis vonhageni (Mutchler, 1938) , A. maccartyi ( Chemsak & Hovore, 2002) , A. piperatus (Gahan, 1892) , and A. wappesi (Galileo, Martins & SantosSilva, 2015) (see photographs on Bezark, 2021). It differs from A. antonkozlovi by the distance between upper eye lobes distinctly wider than width of one lobe (about as wide as one lobe in A. antonkozlovi ), pronotal pubescence mostly yellowish-brown (mostly whitish in A. antonkozlovi ), and different elytral pubescent pattern; from A. arizonicus by the antennomeres V and VI without central pubescent ring (present in A.arizonicus ), distance between upper eye lobes about as wide as maximum width of the scape (distinctly wider than maximum width of the scape in A. arizonicus ), and different elytral pubescent pattern; from A. chamelae by the antennomere III distinctly longer than prothoracic length in male (about as long in male of A. chamelae ), and different elytral pubescent pattern; from A. galapagoensis williamsi , A. galapagoensis galapagoensis , and A.galapagoensis vonhageni by the different elytral pubescent pattern, with central dark band descending from sides to suture (ascending from sides to suture in the three subspecies of A. galapagoensis ); from A. maccartyi by the distance between upper eye lobes about as wide as maximum width of the scape in both sexes (distinctly wider than maximum width of the scape in A. maccartyi ), anterior area of the mesoventral process not distinctly concave ( Fig. 4E ) (distinctly concave in A. maccartyi – Fig. 4H ), and different elytral pubescent pattern; from A. piperatus by the elytral punctation distinctly sparser (denser in A. piperatus ), and different elytral pubescent pattern; finally, it differs from A. wappesi by the pubescence on head and pronotum sparser and mostly darker (denser and lighter in A. wappesi ), and different elytral pubescent pattern. The general appearance is also slightly similar to that of A. robustus Santos-Silva, Botero & Wappes, 2020 , but differs by the distance between upper eye lobes about as wide as maximum diameter of the scape (distinctly wider in A. robustus ), and by the central area of the mesoventral process slightly longitudinally elevated ( Fig. 4E ) (distinctly elevated in A. robustus – Fig. 4I ).
