Diagnosis

In the key to species of Calotelea by Kamalanathan et al. (2022), C. fulva Rajmohana & Debnath sp. nov. comes close to C. trikona Veenakumari & Popovici, 2022 . But C. fulva can be distinguished by a metascutellar lamina medially concave and notched (in C. trikona , metascutellar lamina triangular), metasoma slender, 3.5× as long as wide (in C. trikona , comparatively wider, only 2.6× as long as wide) and a mesoscutal suprahumeral sulcus foveolate (in C. trikona , mesoscutal suprahumeral sulcus smooth). However, in the key provided here, C. fulva comes close to C. kannagiae Veenakumari & Popovici, 2022 . But C. fulva can be distinguished from the latter by the following characters: head black (in C. kannagiae , brown); fore wing without vertical band (in C. kannagiae , vertical band present basally); horn on T1 smooth (in C. kannagiae , reticulte); pronotal suprahumeral sulcus smooth (in C. kannagiae , foveolate); OOL 0.5× OD (in C. kannagiae , lateral ocellus contiguous with orbit).

Etymology

The specific epithet is after the Latin word ‘ fulvus ’ = ‘dark’, due to its dark, brown color.
