CLADISTIC AND BIOGEOGRAPHIC ANALYSES OF HAWAIIAN PIPUNCULIDAE (DIPTERA) REVISITED

Pipunculidae (Diptera) of the Hawaiian islands belong to the endemic h awaiiensis subgroup of the subgenus Cephalops (Semicephalops). In tota l 36 species are known from the Hawaiian islands. Cladistic analysis o f 31 species, using 21 morphological characters from the male terminal ia, resulted in 480 equally parsimonious trees. Three rounds of succes sive weighting resulted in 610 equally parsimonious trees. A biogeogra phic analysis was carried out, using the three-area statement techniqu e and based on the strict consensus tree produced from the tree set ob tained by successive weighting. The analysis puts the sequence of the island groups in congruence with the geological history of the islands . The results of the cladistic and biogeographic analyses were compare d with earlier similar analyses. (C) 1996 The Willi Hennig Society.
