Diagnosis
In the key to species of Calotelea by Kamalanathan et al. (2022), C. acuta Rajmohana & Debnath sp. nov. comes close to C. laminaris Rajmohana, 2013. But C. acuta can be distinguished by a slender, narrow metasoma, 4.3× as long as wide (in C. laminaris, 3.5 × as long as wide), a foveolate pronotal cervical sulcus (in C. laminaris, pronotal cervical sulcus smooth), the presence of a mesopleural carina (in C. laminaris, mesopleural carina absent) and pm> 3.0× as long as m (in C. laminaris, pm <3.0× m).
Etymology
The specific epithet is after the Latin word ‘ acutus ’ = ‘pointed’, due to the shape of the metasomal apex.
