Stenoeme aguilari Galileo & Martins, 2010 ( Figs. 4 A-4D)

Stenoeme aguilari Galileo & Martins, 2010: 32 .

Remarks: This species was described based on a single male from Paraguay (Concepción). Currently, it remains known only from the holotype ( Bezark, 2024a; Monné, 2024a; Tavakilian & Chevillotte, 2023). Galileo & Martins (2010) compared S. aguilari with S. bellarmini Gounelle, 1909 , and S. annularis Martins, 1980 ( Fig. 4E ) (translated): Stenoeme aguilari differs from S. annularis by the unicolorous antennae (flagellomeres reddish with dark apex in S. annularis ), and black body and legs [actually, dark brown] (reddish brown [actually, partially brown, partially dark brown, and partially orangish brown, with the colors variable in area and disposition in the specimens] in S. annularis ). It differs from S. bellarmini by the general black and dark brown color [actually, dark brown], with the color of the elytral apex not differing from the remaining elytral surface (body brownish-ochraceous and the elytral apex is darker than the remaining elytral surface in S. bellarmini ).

Galileo & Martins (2010) did not comment on the dorsal surface of metafemora having no erect and somewhat spatulate setae ( Fig. 4D ), whereas they are present in S. annularis ( Fig. 4E ). This feature alone allows for the separation of S. aguilari from S. annularis without relying on colors. It is noticeable that the figure of the holotype of S. bellarmini on Bezark (2024b) is from "Santo Antonio da Barra,″ while Gounelle (1909) described it from Condeúba, a municipality in the Brazilian state of Bahia. However, Santo Antonio da Barra has been named Condeúba since 1889. Comparing the dorsal colors in the holotype of S. bellarmini (see photograph on Bezark, 2024b) with those in the holotype of S. aguilari ( Fig. 4B ), we cannot see a reliable difference: they appear to be the same or nearly so. Furthermore, we examined specimens of S. aguilari with the elytral color distinctly lighter ( Fig. 4A ) than that in the holotype, suggesting that the colors are variable in the species. As the original description of S. bellarmini is short and does not provide essential details, including the presence or absence of erect setae on the dorsal surface of metafemora, we can only provisionally differentiate it from S. aguilari by the narrowly darker elytral apex in the former. Stenoeme furca Nascimento & Bravo, 2018 ( Fig. 4F ) also has no erect setae on the dorsal surface of the metafemora. However, it differs from S. aguilari especially by the metafemoral club being distinctly stouter. Stenoeme kempfi Martins, 1988 ( Fig. 4G ) differs from S. aguilari by the metafemora being stouter and with distinct erect setae dorsally; and S. iheringi Gounelle, 1909 (see photograph on Bezark, 2024b; species examined only through the photograph of the holotype) by the prothorax in male not being constricted posteriorly.

Material examined: BRAZIL (new country record), São Paulo: Piracicaba (22°42′37.10″S, 47°37′25.84″W), [pheromone trap], 3 males ( MZSP 61426 ; MZSP 61429 ; MZSP 61430 ), 24.X.2019, W.D. Silva leg. ( MZSP) .
