- A taxonomic revision of the Neotropical termite genera Labiotermes Holmgren and Paracornitermes Emerson (Isoptera: Termitidae: Nasutitermitinae)
Abstract
The taxonomy of the South American termite genus Labiotermes Holmgren (sensu novo) is revised, including identification keys to soldiers and workers, and distribution maps for all 10 species. Paracornitermes Emerson is treated as a new synonym of Labiotermes. Two new species are described: L. guasu, from the Amazon rain forest and L. oreadicus, from the Cerrado of central Brazil. Paracornitermes caapora Bandeira & Cancello and P. hirsutus Araujo are placed under the synonymy of L. orthocephalus. The imagos of L. emersoni and L. orthocephalus are described for the first time. The workers of all species are described and illustrated, including the enteric valve armature and the mixed segment. The soldiers of the species previously included in Paracornitermes are redescribed.
- The complete mitochondrial genomes of the higher termites Labiotermes labralis and Embiratermes neotenicus (Termitidae: Syntermitinae)
Abstract
The complete mitochondrial genomes (mitogenomes) of two higher termites were reconstructed from the metagenomes of individual gut compartments with more than 2000-fold coverage. The circular mitogenomes of Labiotermes labralis (accession number KY436201) and Embiratermes neotenicus (accession number KY436202) have a length of 15,935 and 15,868 bp and an overall G + C content of 30.7 mol% and 33.7 mol%, respectively, and both have an asymmetric nucleotide composition. Genome structure and orientation are the same as in other termites and in the ancestral insect mitogenome. These data further expand arthropod mitogenome databases, which have become an important resource in ecological, phylogenetic and evolutionary studies.
- Isolation and characterization of microsatellite markers in Labiotermes labralis (Isoptera, Termitidae, Nasutitermitinae)
Abstract
We report here on the development of six polymorphic microsatellite loci for Labiotermes labralis. This soil‐feeding species is restricted to the Neotropical rainforest and then could represent a major candidate for being a bio‐indicator of anthropic disturbance resulting in the forest fragmentation. The microsatellite loci were isolated and characterized using a microsatellite‐enriched genomic library. The primers were tested on a French Guyanese population of L. labralis, represented by the sampling of one soldier in 22 nests. The primers were also tested against nine species of the same Nasutitermitinae subfamily and were successfully amplified at five loci in Armitermes minutus.

Composition of the gut microbiota
According to the abstract, Marynowska et al. (2023) studied the compartmentalised gut of the soil-feeding Labiotermes labralis and found that Firmicutes dominate the bacterial community and decline in relative abundance from the foregut towards the hindgut, whereas Bacteroidetes, Proteobacteria and Verrucomicrobia increase; the symbionts express many carbohydrate-active enzymes (CAZymes) degrading cellulose and hemicellulose, and the host's own cellulases differ in origin and structure.
