1. Revision of the Termitinae with snapping soldiers (Isoptera: Termitidae) from New Guinea

   Thomas Bourguignon, Maurice Leponce, Yves Roisin · 2008 · Zootaxa

   Resumen

   Up to now, three described species of Termitinae with snapping soldier mandibles (the Termes–Capritermes group) were known from New Guinea: Termes odontomachus (Desneux), Macrognathotermes errator Miller and Pericapritermes schultzei (Holmgren). Here, we report the presence of seven additional species, among which three are new to science: Pericapritermes parvus, P. pilosus and P. papuanus. The other four, collected in southern Papuan savannas, were previously known from northern Australia: Ephelotermes paleatus Miller, E. cheeli (Mjöberg), Lophotermes aduncus Miller, and L. brevicephalus Miller. We reassign T. odontomachus to Protocapritermes Holmgren. Diagnostic characters andillustrations are provided for all species. The Oriental affinities of the forest fauna of New Guinea and the similarities between Australian and New Guinean savannas are emphasized.

2. A molecular survey of Australian and North American termite genera indicates that vertical inheritance is the primary force shaping termite gut microbiomes

   Resumen

   BACKGROUND: Termites and their microbial gut symbionts are major recyclers of lignocellulosic biomass. This important symbiosis is obligate but relatively open and more complex in comparison to other well-known insect symbioses such as the strict vertical transmission of Buchnera in aphids. The relative roles of vertical inheritance and environmental factors such as diet in shaping the termite gut microbiome are not well understood. RESULTS: The gut microbiomes of 66 specimens representing seven higher and nine lower termite genera collected in Australia and North America were profiled by small subunit (SSU) rRNA amplicon pyrosequencing. These represent the first reported culture-independent gut microbiome data for three higher termite genera: Tenuirostritermes, Drepanotermes, and Gnathamitermes; and two lower termite genera: Marginitermes and Porotermes. Consistent with previous studies, bacteria comprise the largest fraction of termite gut symbionts, of which 11 phylotypes (6 Treponema, 1 Desulfarculus-like, 1 Desulfovibrio, 1 Anaerovorax-like, 1 Sporobacter-like, and 1 Pirellula-like) were widespread occurring in ≥50% of collected specimens. Archaea are generally considered to comprise only a minority of the termite gut microbiota (<3%); however, archaeal relative abundance was substantially higher and variable in a number of specimens including Macrognathotermes, Coptotermes, Schedorhinotermes, Porotermes, and Mastotermes (representing up to 54% of amplicon reads). A ciliate related to Clevelandella was detected in low abundance in Gnathamitermes indicating that protists were either reacquired after protists loss in higher termites or persisted in low numbers across this transition. Phylogenetic analyses of the bacterial communities indicate that vertical inheritance is the primary force shaping termite gut microbiota. The effect of diet is secondary and appears to influence the relative abundance, but not membership, of the gut communities. CONCLUSIONS: Vertical inheritance is the primary force shaping the termite gut microbiome indicating that species are successfully and faithfully passed from one generation to the next via trophallaxis or coprophagy. Changes in relative abundance can occur on shorter time scales and appear to be an adaptive mechanism for dietary fluctuations.

3. Vibrational signatures and mimicry in ant-termite and termite-termite interactions

   Resumen

   Eusocial insects fascinate researchers with their sophisticated communication systems and sensory specialisations. Ants and termites have coexisted in a long-standing predator–prey arms race, offering insight into the interplay between ecology and evolution. The subterranean termite Coptotermes acinaciformis can detect the predatory ant Iridomyrmex purpureus through footstep-induced vibrations, triggering defensive responses. Ants produce noisier walking signatures than termites, while the inquiline termite Macrognathotermes sunteri walks more quietly than its host, suggesting species-specific vibroacoustic strategies. Using statistical analysis of video-tracked motion and footstep vibrations in confined arenas across six ant and ten termite species, we show that C. acinaciformis, despite its body size, moves more smoothly than ants, which alternate between directed and erratic paths. Inquiline termites, by contrast, displayed erratic movements. Ants consistently produced stronger vibrations closely linked to body mass, while Highly Comparative Time Series Analysis revealed termite motions approaching chaotic dynamics. Notably, while C. acinaciformis and I. purpureus produced distinct vibrational signatures, M. sunteri ’s signals overlapped with its host, consistent with vibroacoustic mimicry. Although the ecological nature of this association remains unresolved, our findings underscore the central role of vibrational cues in shaping interspecific dynamics and highlight vibroacoustic communication as an underappreciated driver of social insect ecology and evolution.
