“…Tibial spurs 3, 2, 2. Crop voluminous, gizzard armature reduced to six pulvilli, one of them (in position 4 according to Romero Arias et al ., 2020) much larger than the other five. All pulvilli bear a group of 25–50 pointed spines, about 10 μm long (Fig.…”

“…Species identifications were based on morphological and anatomical characters, which included the worker digestive tube configuration, the shape of the gizzard and enteric valve armature, as described in Romero Arias et al . (2020). The taxon sampling attempted to maximize the number of species and their geographic distribution, including samples of Astalotermes and Anoplotermes groups in addition to new morphologically‐characterized specimens.…”

“…The shape of the mesenteron–proctodeum junction forming a mixed segment and the morphologically variable enteric valve armature are the conventional characters used for the Apicotermitinae taxonomy (Grassé & Noirot, 1955; Sands, 1972, 1998; Noirot, 2001). The gizzard ornaments are also useful as taxonomic characters, particularly in the African soldierless species (Noirot, 2001; Romero Arias et al ., 2020). Although some genera are characterized by conspicuous apomorphies, such as the hypertrophied sclerotized cushion 1 of the enteric valve in Ateuchotermes Sands, others mostly accommodate species that lack particular diagnostic features, such as Astratotermes Sands, whose enteric valve lacks distinctive characters (Sands, 1972).…”

Soil‐feeding termites are abundant in tropical regions and play an important role in soil bioturbation and in the organic matter cycle. The Apicotermitinae are arguably the most diverse lineage of soil‐feeding termites, but they are also the most understudied, probably because many species are soldierless, which makes identification difficult. Although the backbone of the termite phylogenetic tree is now well‐resolved, the relationships among representatives of Apicotermitinae are still largely unknown. Here, we present phylogenetic trees inferred from 113 mitochondrial genomes of Apicotermitinae representative of the group diversity. Our analyses confirm the monophyly of the Apicotermitinae and the basal position of soldiered taxa, within which two lineages of soldierless species are nested. We describe two new monotypic genera, whose phylogenetic position appeared of special interest: Koutabatermes gen. n., lies on a long branch among soldiered taxa, and Apolemotermes gen. n., is sister to Adaiphrotermes. We resolved, with high support, the position of Asian genera as sister group of a clade comprising the monophyletic neotropical Anoplotermes‐group and the small African clade including Adaiphrotermes and Apolemotermes gen. n.. Our trees cast light on the intergeneric and interspecific relationships within Apicotermitinae and reveal the polyphyly of several genera, including Ruptitermes, Astalotermes and Anoplotermes. Biogeographic reconstructions revealed two dispersal events out of Africa, one to the Oriental realm and one to the Neotropical realm. Overall, the timing of Apicotermitinae diversification and dispersal, following the Eocene–Oligocene boundary, matches that found for other groups of Neoisoptera.

“…Apicotermitinae (Blattodea: Isoptera) are known for being soldierless termites, however, some basal species still have the soldier caste and are only found in Africa and Asia Romero Arias et al 2020). In the Neotropical Apicotermitinae, the solider caste is not present (Constantino 2022).…”
