Dielis tejensis is a species of scoliid wasp. It is endemic to Texas.[1]
The specific epithet comes from the latinized form of "Tejas", the Spanish name for Texas.
The species is only known from male specimens and was described in 2023 based on genetic differences to other Dielis species. It is chromatically distinguished from the males of all other North American species of the tribe Campsomerini (except for D. pillipies) by having five stripes along its abdomen rather than four.
As with most species of scoliid wasps, it is thought to parasitize soil-inhabiting Scarabaeoidea beetle grubs. However, the exact host for its larva is currently unknown.
Dielis tejensis is currently only known from Texas from the gulf coast west to Kent county.[1]
