Description
Summary:ABSTRACT 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. RESUMO Dihoplotermes, que era um gênero monotípico, agora é composto por duas espécies. Dihoplotermes taurus sp. nov., uma nova espécie de cupim Termitinae, é descrita e ilustrada com base nos caracteres morfológicos dos soldados, operários e imago. A nova espécie se diferencia de Dihoplotermes inusitatus Araujo por apresentar uma protuberância em forma de espinho não pontiagudo no posmento, presença de um espinho na moela e ausência de soldados dimórficos. Além disso, são descritas pela primeira vez as características morfológicas internas de um operário de Dihoplotermes e utilizamos ambos caracteres morfológicos internos e externos para melhor caracterizar as espécies.
