Hornectes quadrimaculatus
Hornectes quadrimaculatus is a species of predaceous diving beetle in the family Dytiscidae, subfamily Hydroporinae. Originally described as Hydroporus quadrimaculatus by Horn in 1883, it was later transferred to the genus Hornectes. The species epithet "quadrimaculatus" (four-spotted) refers to its characteristic elytral maculation. It belongs to the tribe Hydroporini within the speciose subfamily Hydroporinae, which contains many small to medium-sized diving beetles.
