EV asymmetric, with an armature composed of three semispherical sclerotized plates that bear several spines: one larger and central, and two smaller, adjacent, non-identical (Fig. 5A and 5D). An occasional single spine, the same size as the spines on the plates, is isolated adjacent to the smaller plate (Fig. 5B). The cushions are subrectangular and elongated, with 30 to 40 elongated scales in the proximal region (some of which may be fringed), and 20 to 30 smaller, entirely fringed scales in the basal portion (Fig. 5C).</p><p><b>Comparison.</b> The left mandible incision between M1+2 and M3 of <i>Triclavitermes catoleensis</i> <b>sp. nov.</b> is wider than in most genera, e.g., <i>Anoplotermes</i>, <i>Krecekitermes</i>, <i>Ourissotermes</i>, but narrower than in <i>Mangolditermes</i>. <i>T. catoleensis</i> <b>sp. nov.</b> differs from <i>Ourissotermes giblinorum</i> Scheffrahn, Carrijo & Castro, 2023 and <i>Echinotermes biriba</i> Castro & Scheffrahn, 2018 by having a more prominent mesenteric tongue. Additionally, <i>E. biriba</i> has a highly enlarged crop, a feature not found in <i>T. catoleensis</i> <b>sp. nov.</b> In <i>O. giblinorum</i>, the EV is inserted directly into the P3, without a distinct EVS, while in <i>T. catoleensis</i> <b>sp. nov.</b>, the EVS is conspicuous. <i>Anoplotermes</i> spp. and <i>Humutermes</i> spp. have a mesenteric tongue with a whitish spherical mesenteric nodule in ventral view, but can be distinguished from <i>T. catoleensis</i> <b>sp. nov.</b> by the shape of the enteric valve seating, which forms a ring in <i>T. catoleensis</i> <b>sp. nov.</b>, absent in <i>Anoplotermes</i> spp. and <i>Humutermes</i> spp. The asymmetric pattern of the EV armature in <i>T. catoleensis</i> <b>sp. nov.</b> closely resembles that observed in <i>Anoplotermes susanae</i> Scheffrahn, Carrijo & Castro, 2023, <i>Anoplotermes janus</i> Bourguignon & Roisin, 2010 (Fig. 6F), and <i>Anoplotermes parvus</i> Snyder, 1923 (Fig. 6G–H), which also feature an armature extending along only one or three of the six cushions, or even along all cushions, yet still asymmetric. <i>Dissimulitermes invisibilis</i> also exhibits an asymmetric enteric valve armature, with similar plates extending across five cushions, and only one cushion bearing a plate of a distinct shape. However, the shape of the armature plates is clearly different among these species. The ornamentation and armature of the enteric valve in <i>T. catoleensis</i> <b>sp. nov.</b> also set it apart from all other genera of Apicotermitinae. The EVs of <i>E. biriba</i>, <i>O. giblinorum</i>, <i>Patawatermes</i> spp. (Fig. 6C–D), and <i>Humutermes</i> spp. have six symmetrical and sclerotized plates with spines, while the EV of <i>T. catoleensis</i> <b>sp. nov.</b> is asymmetrical, with only three distinct sclerotized plates. Although <i>Rustitermes boteroi</i> was recovered as close related to <i>T. catoleensis</i> <b>sp. nov.</b> in the Bayesian inference (BI) tree (Fig. 8, see results below), its morphological traits are markedly different. It lacks an armed enteric valve, exhibits a distinct coiling pattern of the digestive tube, and has a row of spines on the foretibia—a feature absent in <i>T. catoleensis</i> <b>sp. nov.</b> <i>Triclavitermes</i> <b>gen. nov.</b> resembles <i>Chasitermes</i> by the ring-shaped arrangement of the EVS, but differs by the EV, as <i>Chasitermes</i> has an unarmed EV with rectangular, non-sclerotized cushions (Scheffrahn & Carrijo 2023).</p> |
