“…Authoritative records of the kalotermitid diversity for Colombia are reported almost entirely from the Caribbean Region ( Casalla et al 2016a , b ; Snyder 1925 ; Krishna and Emerson 1962 ; Scheffrahn 2019a , b ). An Andean termite survey by Parra and Soto (1992) is a remarkable exception as they report ten kalotermitids from this region.…”

“…All samples were identified to genus level and sorted to morpho‐species using taxonomic soldier traits (Casalla et al., ,b; Constantini & Cancello, ; Constantino, , ; Krishna, ; Krishna & Araujo, ; Krishna, Grimaldi, Krishna, & Engel, ; Scheffrahn & Křeček, ). A representative of each sample (specimen) was also sequenced using genetic markers (barcoding approach, see below) to corroborate morphological identification.…”

“…Samples forming a well‐supported cluster were named identically. Species names were carefully checked with available literature and correspond to those reported for Neotropical termites (Bourguignon et al., ; Cameron, Lo, Bourguignon, Svenson, & Evans, ; Casalla et al., ,b; Eaton et al., ; Inward et al., ; Roy et al., ). Voucher specimens of all species are held at the University of Freiburg, Germany, and will be deposited at the Natural History Museum of the Alexander von Humboldt Institute of Bogotá (MIAvH).…”

“…In lowland tropical forests, termite species diversity is high (e.g., Bignell & Eggleton, ; Bourguignon, Leponce, & Roisin, ; Eggleton, Davies, Connetable, Bignell, & Rouland, ; Eggleton, Bignell et al., ) and new species are continuously discovered and described (Casalla, Scheffrahn, & Korb, ,b; Eggleton, ; Postle & Scheffrahn, ). To untangle termite diversity, the use of molecular techniques has been shown to be an important tool for identification of species that are problematic to determine only by morphology (Bourguignon, Sobotnik, Dahlsjo, & Roisin, ; Hausberger, Kimpel, Neer, & Korb, ; Inward, Vogler, & Eggleton, ; Roy, Demanche, Livet, & Harry, ).…”

Termites are ecosystem engineers that play an important role in the biotransformation and re‐distribution of nutrients in soil. The dry forests are endemic repositories, but at same time, they are most threatened by extensive livestock and crop farming, fires, and climate change. In Colombia, the best‐protected dry forests are located in the north. The termite fauna of dry forests are poorly known. The aim was to identify the termite species occurring in tropical dry forests of the Colombian Caribbean coast in relation to diet and precipitation, temperature, elevation, and soil properties. A total of 32 species in 1,103 occurrences were found. Termitidae accounted for 78% of the species richness with the Anoplotermes‐group, Microcerotermes, and Nasutitermes being the dominant genera. Differences in species composition and abundance were found across sites. These differences may be linked to anthropogenic disturbance and polygyny and polydomy. Strikingly, our highest elevation site (334 m) had the highest species richness much higher than the two lower elevation sites. This implies an inversion of the common elevation‐diversity gradient, also found for termites which can be explained by increasing precipitation with elevation in the dry forest. An analysis of termite species richness at the global scale confirms that termite species richness correlates positively with rainfall. Hence, rainfall seems to positively affect termite diversity. In line, the studied Colombian tropical dry forests had low diversity compared to rain forests. A decline of species‐rich soil‐feeding termites with increasing aridity may explain why the highest termite diversity occurs in humid tropical rain forests.

Protist symbionts of termites: diversity, distribution, and coevolution

The symbiosis between termites and their hindgut protists is mutually obligate and vertically inherited. It was established by the late Jurassic in the cockroach ancestors of termites as they transitioned to wood feeding. Since then, protist symbionts have been transmitted from host generation to host generation by proctodeal trophallaxis (anal feeding). The protists belong to multiple lineages within the eukaryotic superphylum Metamonada. Most of these lineages have evolved large cells with complex morphology, unlike the non‐termite‐associated Metamonada. The species richness and taxonomic composition of symbiotic protist communities varies widely across termite lineages, especially within the deep‐branching clade Teletisoptera. In general, closely related termites tend to harbour closely related protists, and deep‐branching termites tend to harbour deep‐branching protists, reflecting their broad‐scale co‐diversification. A closer view, however, reveals a complex distribution of protist lineages across hosts. Some protist taxa are common, some are rare, some are widespread, and some are restricted to a single host family or genus. Some protist taxa can be found in only a few, distantly related, host species. Thus, the long history of co‐diversification in this symbiosis has been complicated by lineage‐specific loss of symbionts, transfer of symbionts from one host lineage to another, and by independent diversification of the symbionts relative to their hosts. This review aims to introduce the biology of this important symbiosis and serve as a gateway to the diversity and systematics literature for both termites and protists. A searchable database with all termite‐protist occurrence records and taxonomic references is provided as a supplementary file to encourage and facilitate new research in this field.
