Abstract

AZEVEDO, Renato Almeida de; DAMBROS, Cristian de Sales  and  MORAIS, José Wellington de. A new termite species of the genus Dihoplotermes Araújo (Blattaria, Isoptera, Termitidae) from the Brazilian Amazonian rainforest. Acta Amaz. [online]. 2019, vol.49, n.1, pp.17-23. ISSN 1809-4392.  http://dx.doi.org/10.1590/1809-4392201800582.

Dihoplotermes, a previously monotypic genus, is now composed of two species. Dihoplotermes taurus sp. nov., a new Termitinae termite species, is illustrated and described based on morphological characters from soldiers, workers, and imago. The new species is distinguished from Dihoplotermes inusitatus Araujo by having a spine-like protuberance with blunt apex on the postmentum, the presence of a spine on the gizzard and the absence of dimorphic soldiers. Furthermore, the internal morphological characteristics of a Dihoplotermes worker are described for the first time. Both internal and external morphological characters were used to improve the characterization of the species.

Keywords : gizzard; soil fauna; taxonomy; termite; Termitinae.
