Type material. Holotype male ( INPA-COL 002854 ) from BRAZIL, Amazonas : Manaus, ZF-2, km 14, 2°35’21”S 60°06’55”W, “Malaise Grande, lado nascente,” 16 m, 24.X–10.XI.2017, J.A. Rafael leg. ( INPA) . Paratype female (MNRJ-ENT-47682): same data as holotype except “Malaise Grande, lado poente,” 25.I–08.II.2018, J.A. Rafael leg.— Rede BIA ( MNRJ) .

Etymology. The species is named in tribute to Dr. Daniela M. Takiya (UFRJ), for her friendship and valuable contributions to the study of insects.

Remarks. Charisia takiyae sp. nov. is similar to Charisia durantoni ( Peñaherrera-Leiva & Tavakilian, 2003) ( Figs 41–42 ), but differs by the pronotal punctures distinctly shorter centrally (finer and denser centrally in C. durantoni ). It differs from Charisia mneme (Newman, 1841) ( Figs 37–38 ) by the pronotal punctures distinctly coarser throughout (distinctly denser and finer in C. mneme ); from Charisia euphrosyne (Newman, 1840) ( Figs 33–34 ) by the pronotal punctures distinctly coarser (denser and finer in C. euphrosyne ) and the pronotum without abundant pubescence on the wide central area (abundantly pubescent in C. euphrosyne ); from Charisia melanaria Gounelle, 1911 ( Figs 35–36 ) by the pronotal punctures distinctly coarser (denser and finer in C. melanaria ), and by the elytra with large and wide yellowish-brown area dorsally, not reaching the base (slender and reaching the base in C. melanaria ). From Charisia ornaticollis Zajciw, 1973 ( Figs 39–40 ), the new species differs by the stouter body (slender in C. ornaticollis ), pronotum without arched yellow pubescent bands on the anterior half (present in C. ornaticollis ), and elytra without dense yellowish pubescence close to suture on the anterior 2/3 (present in C. ornaticollis ). We did not examine specimens of Charisia bleuzeni (Peñaherrera-Leiva & Tavakilian, 2004) . However, the photographs of the holotype (see Bezark (2024) and Peñaherrera-Leiva & Tavakilian (2003)) allow to see that the pronotal punctures are distinctly finer than in C. takiyae , the yellowish dorsal macula on elytra is obliquely band-shaped (not so in C. takiyae ), and the ventral surface of metafemora and metatibiae has erect setae much denser than in C. takiyae .
