| Sumario: | The soldierless Neotropical Apicotermitinae is considered among the less known termite groups and its ecological relevance warrants studies about the biology y diversity of their species. We investigated the presence, distribution and relative abundance of the recently described species Compositermes vindai Scheffrahn, 2013 in natural and anthropized ecosystems of northeastern Argentina. Their nests and populations, as well as their presence inside other Termitidae mounds were examined. A standardized sampling protocol for termites was applied at five sites, with 100 x 2 m transects. Worker morphometric data from the surveyed localities are also reported. C. vindai was found in protected environments with little disturbance as well as in other altered ecosystems. The abundance patterns of C. vindai in the sampled areas varied from rare to intermediate and seemed not to be significantly affected by the environmental changes of the sites due to their land uses. The microhabitats occupied were mainly superficial soil and other Termitidae mounds (Cornitermes cumulans Kollar, 1832; Syntermes obtusus Holmgren, 1911 and Cortaritermes fulviceps Silvestri, 1901). C. vindai subterranean and diffuse nests showed a core surrounding by scattered chambers and tunnels extending into the surrounding soil. The small size colonies comprised workers, brachypterous nymphs and white immature larvae. Winged imagoes or primary reproductives were not found. These new records also extend the distribution of C. vindai across the biomes and ecoregions of the Neotropical ecozone and constitute the first reports of C. vindai from Argentina. |
