03DAE569EF78654EB6C9717C6E108C84.taxon	discussion	Comparisons The new genus exhibits external characteristics that are very similar to some species of Aparatermes Fontes, 1986, such as the coloration of the head capsule and spines present on the legs (Pinzón Florian et al. 2019) (Fig. 1 A, B). However, the size of the individuals of the new genus exceeds the size of the Aparatermes spp. (Table 1), and the left mandible of Tucupitermes gen. nov. has a cutting blade length twice as long as the distance between the apical tooth and M 1 + 2, differing from some Aparatermes (A. abbreviatus, A. silvestrii, A. thornatus – personal observations) (Fig. 1 E and Table 1). In Aparatermes the mesenteric tongue is short and non-globular, whereas in Tucupitermes gen. nov. is long, widened and slightly globular (Fig. 2 C, F). This characteristic is uncommon for medium / largesized Apicotermitinae, being described for Patawatermes Bourguignon & Roisin 2016, and for small-sized termites, such as Anoplotermes Müller 1873, Chasitermes Scheffrahn & Carrijo 2023, Disjunctitermes Scheffrahn 2017 and Humutermes Bourguignon & Roisin 2016. Furthermore, the P 1 – P 3 connection in Tucupitermes gen. nov. is only visible with dissection (Fig. 2 G, H), while in Aparatermes it can be observed in dorsal view in situ. The P 1 – P 3 connection visible only with dissection is uncommon in the Neotropical Apicotermitinae, only known for Anoplotermes parvus (Bourguignon et al. 2010). The shape and size of the enteric valve seating, which is bilobed, with very small lobes is also unique in the new genus (Fig. 2 I). The absence of scales around the lobes of the enteric valve of Tucupitermes gen. nov. (Fig. 2 J, K) is shared with Aparatermes, but also Ruptitermes and Mangolditermes (Acioli & Constantino 2015; Carrijo et al. 2023), so this structure is not determinant to distinguish these genera. The length of the stomodeal valve in Tucupitermes gen. nov. is extremely long, and was not previously observed in any other Apicotermitinae. This is also true for the Malpighian ampullae, that have not been reported in any genus of soldierless termites, but it may have gone unnoticed in some species of Aparatermes Fontes, 1986 and Ruptitermes Mathews, 1977 (Personal observations of Aparatermes thornatus, Aparatermes silvestrii and Ruptitermes spp.). However, these two genera have features distinct from Tucupitermes gen. nov., such as the short mesenteric tongue, the trilobed enteric valve seating, and an enteric valve with well-developed spines (Fontes, 1986; Pinzón Florian et al. 2019) Acioli and Constantino, 2015).	en	Almeida-Azevedo, Rayssa, Acioli, Agno Nonato Serrão, Heleodoro, Raphael, Morais, José Wellington De, Brown, George Gardner, Kille, Peter, Cunha, Luis, Azevedo, Renato Almeida De (2025): Tucupitermes, the largest Apicotermitinae (Isoptera, Termitidae) from the Amazon Rainforest.
