SÆTHER, O. A. & WANG, X. Revision of the genus Paraphaenocladius Thienemann, 1924 of the world (Diptera: Chironomidae, Orthocladiinae). 1995. 69 pp. SEK 120.
Abstract:
Generic diagnosis to all stages of the genus Paraphaenocladius are given. A synapomorphic diagram showing Paraphaenoclaius as a sistergroup of Parametriocnemus is presented. In addition a parsimony analysis using the PAUP program is given. The genus is divided into 5 spcies groups, the irritus , dewulfi, proprius, penerasus, and impensus groups. Keys to male and female imagines, pupae and larvae are given. — 23 taxa including 16 species and 7 subspecies are decribed or redecribed. The genus is nearly exclusively Holarctic with only the dewulfi group Afrotropical. The differentiation into subspecies and some species appears to have taken place as a result of postglacial and interglacial vicariance events.
