  • Dendrorhynchus systeni[1]
  • Dendrorhynchus keilini[2]

Dendrorhynchus is a gregarine genus with total 2 species.[3] The genus was first described in 1920 by David Keilin from the alimentary canal of dolichopodid larvae Systenus.[1]


Dendrorhynchus is a senior homonym for genera of nemerteans (replaced with Polydendrorhynchus)[4] and pterosaurians (replaced with Dendrorhynchoides).[5]
