Abstract
Three instars of Canthyporus kenyensis Bilardo & Sanfilippo, 1979 are described. Larvae of C . kenyensis differ from other known larvae of the subfamily Hydroporinae in having the primary procoxal seta CO7 articulated distally. A parsimony analysis of selected taxa of Hydroporinae based on 19 informative larval characters was conducted using the program PAUP*. The six most parsimonious trees support a placement of Canthyporus Zimmermann outside the tribe Hydroporini based on the fully sclerotised abdominal segment 6 and the absence of the primary seta UR8.
