Diagnosis. Epelaspis tavoi Lima & Fernandes, sp. nov. can be distinguished from all other Neotropical species of Epelaspis by the combination of the following characters: (1) lateromedian longitudinal carina with vestigial part on apex and anterior portion of area petiolaris (Fig. 12D); (2) lateral longitudinal carina absent (Fig. 12D); (3) ovipositor with lower valve with two teeth on apex; (4) tergite 1 with lateromedian carina present on posterior part (Fig. 12B).

Scutellum mat, granulated with punctation and short setae. Propodeum polished, weak granulated with sparse punctation and setae; area basalis not anteriorly delimited; area superomedia not laterally delimited; posterior transverse carina with small crest; lateral longitudinal carina absent; lateromedian longitudinal carina incomplete with vestigial part on apex and anterior portion of area petiolaris; without sulcus above pleural carina on the portion of area dentipara (Fig. 12D). Fore wing without ramulus (Fig. 12E). Legs with punctation, short setae and tarsus with denticles, one tibial spur in fore leg, two asymmetrical tibial spurs in mid leg and hind leg.

Host. Unknown.
Etymology. The specific epiphet tavoi is in honor of the late Gustavo Alberto Suarez Osorio—Tavo, whose life was intricately woven with the landscape of Antioquia’s southwest, where his intimate knowledge of its forests and mountains began from a young age. Gustavo’s involvement in monitoring and rediscovery bird expeditions and land conservation efforts further solidified his legacy in protecting biodiversity. His work provided the foundation for the establishment of the Mesenia-Paramillo nature reserve. Tavo’s profound impact on conservation and community service is a testament to his unwavering dedication, leaving an indelible mark on the landscape he cherished.
Discussion. Epelaspis tavoi Lima & Fernandes, sp. nov. is most similar to the E. boteroi Lima & Fernandes, sp. nov. for the fore wing without ramulus, metapleuron polished, granulate with sparse punctation and area below juxtacoxal carina with punctation. However, E. tavoi Lima & Fernandes, sp. nov. differs from E. boteroi Lima & Fernandes, sp. nov. in the following characters: lateral longitudinal carina of propodeum absent (present in E. boteroi Lima & Fernandes, sp. nov.) and scuto-scutellar groove smooth (rugae in E. boteroi Lima & Fernandes, sp. nov.).
