Type material. Holotype female from GUATEMALA, Santa Rosa: Finca Miramundo , 1.VII.2000, J. Monzon leg. ( TAMU, formerly DHCO).

Etymology. Named for the country of Guatemala where the type was collected.

Remarks. The key by Linsley (1963) to species from the United States of America leads Aneflomorpha guatemalana sp. nov. to the alternative of couplet “14” with A. subpubescens (LeConte, 1862) (see photographs on Bezark (2024) and Lingafelter (2022)). The new species differs from A. subpubescens by the pronotum not abundantly and coarsely punctate (abundantly and coarsely punctate in A. subpubescens ), and the elytral apex wider and not spiniform on outer angle (narrower and spiniform on outer angle in A. subpubescens ).

The key by Lingafelter (2022) leads Aneflomorpha guatemalana to the alternative of couplet “19,” when considering the basal area of the dorsal surface of the protibiae with a longitudinal carina, with A. linearis (LeConte, 1859) (see photographs on Bezark (2024) and Lingafelter (2022)) and A. paralinearis Lingafelter, 1922 (see photographs on Bezark (2024) and Lingafelter (2022)). The new species differs from A. linearis by the pronotum with very sparse pubescence on the wide central area (moderately abundant in A. linearis ), outer apical angle of the elytra not dentate (dentate or somewhat spiniform in A. linearis ), and the elytral pubescence shorter (longer in A. linearis ). Aneflomorpha guatemalana differs from A. paralinearis by the prothorax shorter and distinctly wider (longer and wider in A. paralinearis ), wide central area of the pronotum with very sparse pubescence (moderately abundant in A. paralinearis ), and the outer apical angle of the elytra not dentate (dentate in A. paralinearis ). Considering that there is no longitudinal carina on the base of the dorsal surface of the protibiae, the key leads the new species to the alternative of couplet “17” with A. minuta Chemsak, 1962 and A. crypt a Lingafelter, 2022. However, A. guatemalana differs notably from both by the prothorax distinctly wider (narrower in these two species).

The key by Chemsak & Noguera (2005) leads Aneflomorpha guatemalana to the alternative of couplet “9” with A. preclara Chemsak & Linsley, 1975 (see photographs on Bezark (2024) and CNC (2024)), and this is the most similar species of Aneflomorpha . The new species differs as follows: head and pronotum distinctly darker than elytra; scape not darkened apically; pedicel and flagellomeres light reddish brown; legs without black areas; and elytral punctures not dense. In A. preclara , the head, pronotum, and elytra have similar color, scape darkened apically, pedicel and flagellomeres blackish, apex of the femora, tibiae, and tarsi blackish, and the elytral punctures are dense.
