Omalisinae

The Omalisinae (formerly family Omalisidae)[1] are a small subfamily of morphologically derived elaterid beetles. The Omalisinae were long considered an independent family in the deprecated family Cantharoidea (more closely related to soft-bodied beetles like fireflies, than click beetles), and later a family in the Elateroidea, but molecular phylogenies have demonstrated the morphological similarity of Omalisinae to other soft bodied beetles is a case of parallel evolution (homoplasy) of their soft bodies, rather than an apomorphy. Members of this beetle subfamily have been reported to have bioluminescent organs on the larvae[2], although no recent publications have confirmed this. Some recent evidence indicated they were the sister group to a clade comprising the families Rhagophthalmidae and Phengodidae (glowworm beetles)[3], however a more comprehensive phylogenetic analysis based on genome sequences strongly supported the Omalisinae as being contained within the Elateridae.[1]

gollark: Or... you could have them communicate with a central thing over a **wired** network?
gollark: Also, it might be hard to match each disk drive to a door or whatever.
gollark: They have a 256-block limit or something, I think.
gollark: I guess.
gollark: And how would that be contacted?
