Diagnosis

As per key to species of Calotelea by Kamalanathan et al. (2022), C. foveata Rajmohana & Debnath sp. nov. is keyed to C. brevinotaularis Veenakumari & Popovici, 2022 . But C. foveata can be distinguished by notauli indicated as a pit anteriorly (in C. brevinotaularis , notauli prominent and present in anterior half), a lateral pronotal area with irregular reticulate sculpture, without any carina (in C. brevinotaularis , anterodorsally, dorsomedially and posterodorsally carinate but medially and posteroventrally smooth), a comparatively less elongate metasoma, only 3.2× as long as wide (in C. brevinotaularis , 3.7× as long as wide); a mesoscutal suprahumeral sulcus foveolate (in C. brevinotaularis , smooth) and a pronotal cervical sulcus foveolate (in C. brevinotaularis , smooth).

Etymology

The species is named ‘ foveata ’ after its foveolate sulci.
