Buninotus palikur Castro-Huertas, Forero & Melo, 2022

Figs 16–21

Material examined.

Brazil, Espírito Santo: Linhares, Reserva Natural Vale [Vale Natural Reserve] (RNV), 19 ° 09 ' S, 40 ° 04 ' W, José Simplício dos Santos leg., 25. i. 2007, 1 female ( MNRJ) .

Comments.

Buninotus palikur was described based on six females from French Guiana ( Castro-Huertas et al. 2023). The female examined here (Figs 16–21 ), although has lost its antennae and hind legs (Fig. 16 ), corresponds well with the description and diagnosis of B. palikur provided by Castro-Huertas et al. (2023). Its general length measured 10.70 mm to the tip of the membrane; the protuberances of the fore lobe are slightly triangular (Figs 16 , 18 ), and the forewings are brownish with pale spots (Figs 16 , 20 ). Diverging from some characteristics recorded in the specimens described by Castro-Huertas et al. (2023), the prothorax is almost uniform brownish without paler portions, the scutellar spine is curved at approximately its middle portion on lateral view (Figs 16 , 18 , 19 ), and the first spiniform setae of fore tibiae are longer (Fig. 21 ). However, we consider these differences as more probably intraspecific differences. If merely interindividual or geographical variations, only future examination of more specimens would allow to clarify their significance.

Distribution.

Brazil (new record) and French Guiana.

Discussion.

There is a need to collect more specimens, including males of Buninotus , for a better understanding of the genus and its species, possibly allowing a more comprehensive study of the systematics of Saicini in general. Finding a specimen of B. palikur in a natural reserve in Atlantic Forest in Brazil expands the distribution of the species and the genus Buninotus to a broader range of biogreographical regions.
