Rhopalophora casignata Martins & Napp, 1989 View in CoL

( Figs 33–35 View FIGURES 33–35 )

Rhopalophora ( R.) casignata Martins & Napp, 1989: 62 View in CoL . Remarks. Rhopalophora casignata View in CoL was described based on a holotype from Ecuador ( Manabí, between Jipijapa and Manta). Currently, it is also known from the Ecuadorian province of Guayas ( Monné 2024a; Tavakilian & Chevillotte 2025). According to the original description, the holotype ( Fig. 35 View FIGURES 33–35 ) is a male. However, it is a female. The true males of this species ( Fig. 33 View FIGURES 33–35 ) have the antennae distinctly longer. According to Napp (2009) on the antennae (translated): in males, “Antennae surpassing the elytral apex in 4.0 articles;” in females, “Antennae surpassing the elytral apex in three articles.” Still according Napp (2009), she examined one male and two females from Ecuador ( Guayas, Guayaquil). The male examined by us agrees with this description of the antennal length, contradicting the original description of the species. Finally, Napp (2009) reported (translated): “ Martins & Napp (1989: 62) make no mention of differentiated areas on the prosternum of the male and describe that the antennae extend beyond the elytral apex by three segments and that the metafemora extend beyond the elytral apex by one-third of the length of the club. In the male examined here, the antennae and metafemora are longer, and the prosternum presents differentiated areas, although they are not very apparent. In the two females examined, the pilosity is generally poorly preserved, which makes comparison with that of the male difficult.” Again, this description of the prosternum in the male agrees very well with the specimen examined by us.

Material examined. ECUADOR, El Oro ( new province record): Arenillas , < 100 m, on flowers, 1 male, 1 female, 19 Feb 2024, J. Vlasak leg. ( MZSP); 9 males and 6 females, same data, ( JVCO) .
