Deilelater is a genus of click beetles in the family Elateridae. They are one of several genera in the tribe Pyrophorini, all of which are bioluminescent. This genus was established by Cleide Costa in 1975, with 7 species split from "Pyrophorus".

Generally very small. Reddish-brown. Pubescence short, not very dense, yellowish. Eyes slightly convex. Front narrow, not prominent. Antennae reaching hind angles of prothorax; second and third segments subequal; the two together of the same length as the fourth. Prothorax more or less convex; luminous spots lateral, flat or slightly convex, visible also in the proepisternum. Abdominal luminous organ small and lamellate. Elytra sides subparallel, rounded to apices. Male genitalia, median lobe abruptly pointed near apex, with small cuticular scales. Female genitalia: bursa copulatrix spiraled and with long spines; elongate sclerotized plates in the median oviduct.
