The imago of N. callimorphus is described for the first time. Nasutitermes callimorphus occurs from Mexico to Paraguay.

One of these, inquilinism, occurs when one species (the inquiline) inhabits the nest built and occupied by another species (the host). Obligatory inquilines must overcome strong constraints upon colony foundation and development, due to limited availability of host colonies.

- - The classification of termites, particularly the diverse Neoisoptera group, needs significant updates due to many incorrectly grouped taxa; researchers propose a new classification based on genomic analyses.
- - The study identifies seven monophyletic family lineages within Neoisoptera and 18 subfamily lineages in the species-rich Termitidae, including several new subfamilies and the revival of some older ones.
- - The new classification method is built on clear monophyletic lineages, which enhances its stability and adaptability for future studies, allowing it to incorporate yet-to-be-discovered species easily.
The neotropical Apicotermitinae is a common and widespread clade of mostly soil-feeding soldierless termites. With few exceptions, species of this group were originally assigned to the genus Müller, 1873. The application of internal worker morphology coupled with genetic sequencing has recently shed light on the true diversity of this subfamily.

- Termites are highly successful insects with a complex gut system, including a diverse microbiome, which allows them to feed on various organic matter, particularly in soil environments.
- A study using multi-omics techniques examined the gut of a soil-feeding termite, Labiotermes labralis, revealing that its gut microbiome is mainly dominated by Firmicutes but also includes other bacterial groups as gut segments change.
- The research found that these termites possess a diverse range of enzymes for breaking down cellulose and hemicellulose, indicating their gut could have significant biotechnological applications due to its unique enzymatic capabilities.
