Abstract

A reanalysis of the species relationships in the genus Phareicranaus Roewer, 1913, here considered the senior synonym of Acanthocranaus Roewer, 1913, Santinezia Roewer, 1923 and Comboyus Roewer, 1943, is carried out, using information unavailable in aprevious analysis (oI Santinezia). Subfamilies Cranainae and Prostygninae may be not monophyletic, since the generic relationships among cranaines are still obscure; it seems that Phareicranaus is closely related to Vent-rivomer Roewer, 1913 and Ventrisudis Roewer, 1963, based on presence of a ventral apophysis on male coxa IV and cylindrical pedipalpal femur. The analysis performed with equal weighting generated 64 equally parsimonius trees (275 steps, ci= .24; ri= .60), and the strict consensus treediffers substantially from previous analyses. Based on results of the equally weigthed cladistic analysis, Phareicranaus is supported by the following unambiguous synapomorphies: penis base of the glans ringed; pedipalpal femur with a stout dorsoapical spine; strong ventral tubercles on pedipalpal femur and; area II invading area I (the two halves do not touch each other).
