Ranjan, Rahul, Singh, Navneet & Kirti, Jagbir Singh, 2022, Review of the genus Locastra Walker (Lepidoptera: Pyralidae: Epipaschiinae) from India, with a new species and a new species record, Zootaxa 5169 (1), pp. 71-78 : 77

Locastra crassipennis ( Walker, 1857) : 558

( Figs 4 , 6 , 10 )

Diagnosis: L. crassipennis along with L. ardua and L. nigralineata are distinct from all the other congeners by the large scape extension. Externally, L. crassipennis is closely similar to L. ardua but is distinct by the postmedial, curved, pale band farther from the outer margin, which is much nearer to the outer margin in L. ardua .Another closely similar species is L. nigralineata but the latter is distinct in phallus without proximal spine, apical sclerotization reduced, and vesica with a small apical spine whereas, in L. crassipennis proximal spine if phallus is present, lateral sclerotization from apex to middle of phallus and vesica without apical spine.
