Pseudagaone cerdai

Pseudagaone cerdai (Tavakilian & Peñaherrera-Leiva, 2007) (Figs 64–68) Neoregostoma cerdai Tavakilian & Peñaherrera-Leiva, 2007: 84. Remarks. This species was described based on females from French Guiana. Currently, it remains known only from the type locality (Monné 2024; Tavakilian & Chevillotte 2024).According to Tavakilian & Peñaherrera-Leiva (2007) (translated): “Body orangish yellow except the parts listed below which are darkened to dark brown: the mandibles, palpi, eyes, a broad centro-longitudinal line on pronotum, scutellum, a broad band located on elytral margin [actually, on sides of the dorsal surface on anterior 2/3 and only reaching the epipleural margin on posterior third], a short sutural band below scutellum, elytral apex, first 3 or 4 antennomeres. The legs are also orangish yellow, except for a broad line running from outer edge of femora to tibiae, invading the entire pro- and mesotarsomeres. The metatibiae and apex of femoral clubs, as well as a femoral macula on upper surface, enlarged on club, are also dark.” The female examined (Figs 64–67) differs from the holotype (Fig. 68) and paratypes female, as well as some other specimens examined through photographs, by the absence of dark longitudinal bands on elytra. However, as we found no morphological differences, and the colors of other parts of the body agree with those found in the specimens from French Guiana, we believe it is just a chromatic variation of Pseudagaone cerdai (Tavakilian & Peñaherrera-Leiva, 2007). Furthermore, chromatic variation is not rare in Rhinotragini as, for example, in Agaone notabilis (White, 1855) and Rhinotragus dorsiger Germar, 1823 (see photographs on Bezark 2025; in Martins & Santos-Silva 2010; and in Santos-Silva et al. 2019). The antennae were described as having dark basal antennomeres and the other, consequently orangish yellow (… except the parts listed below, which are darkened to dark brown …). However, it is possible to see that the antennomeres from V are partially orangish, especially ventrally. The specimen examined by us has the ventral surface orangish, except the dark apex, and the dorsal surface entirely dark, except the extreme apex of XI. Based on photographs of specimens examined through photographs, the shape of the pronotal dark band is variable, the scutellum may be entirely dark or orangish on apex, the width of the elytral sutural band is variable, from narrow to wide, and the abdominal ventrites 2–4 is dark, a feature not reported in the original description. Material examined. BRAZIL (new country record), Amazonas: Manaus, ZF-2, km14, 2°35’21”S 60°06’55”W, “ Malaise Grande, lado nascente,” 8 m, 1 female, 4–23.X.2017, J.A. Rafael leg. (INPA).

Abstract

Currently, it remains known only from the type locality (Monné 2024; Tavakilian & Chevillotte 2024).According to Tavakilian & Peñaherrera-Leiva (2007) (translated): “Body orangish yellow except the parts listed below which are darkened to dark brown: the mandibles, palpi, eyes, a broad centro-longitudinal line on pronotum, scutellum, a broad band located on elytral margin [actually, on sides of the dorsal surface on anterior 2/3 and only reaching the epipleural margin on posterior third], a short sutural band below scutellum, elytral apex, first 3 or 4 antennomeres.
