Parachorenta demezi Delahaye & Santos-Silva 2016

Parachorenta demezi Delahaye & Santos-Silva, 2016 (Figs 37–40) Parachorenta demezi Delahaye & Santos-Silva, 2016: 2. Remarks. This species was described and remains known only from the holotype male from Peru (Junín) (Monné 2024c; Tavakilian & Chevillotte 2024). The main differences between the female and the holotype male are (sexual dimorphism): 1. Head and prothorax mostly brown (dark brown in the male holotype); 2. Antennae distinctly shorter, not reaching posterior third of elytra (surpassing elytral apex in the male holotype); 3. Distance between upper eye lobes slightly wider than maximum diameter of scape (slightly wider than 2.5 times maximum diameter of scape in the male holotype); 4. Upper eye lobes narrower (wider); 5. Gulamentum punctate (gulamentum rugose-punctate in the male holotype); 6. Prothorax distinctly narrower, with three long, subtriangular tubercles, one near base, and two on posterior third (noticeably wider in the holotype male, with the lateral tubercles located in the same position as in females, but only as a small triangular projection); 7. Elytra mostly shiny, metallic greenish, more greenish-brown or brownish on some areas, especially depending on light intensity and source (not shiny metallic and dark brown basally and gradually lighter toward apex in the male holotype); 8. Femora slender (wider in the male holotype). Although some features may, at first view, suggest that the specimen examined is not the female of P. demezi, these differences are found in some species of other genera of American Callipogonini. For example, the size of the upper eye lobes is considerably different in males and females of Seticeros tunupai Perger & Santos-Silva, 2010, and the integumental color may be noticeably different and may be somewhat metallic (see photographs on Bezark (2025), Perger & Santos-Silva (2010); and Vlasak & Santos-Silva (2021)). In the same way, although the shape of the prothorax is often similar in males and females of other genera of Callipogonini, it may be very different as for example, in Trichocnemis LeConte, 1851 and some species of Callipogon (Callipogon) Audinet-Serville, 1832.
