Abstract

The mature larval stages of 11 species of Polyrhachis from Malaysia are described. For 5 of these species (armata, bihamata, muelleri, scissa and yps i I on) all 5 instars are described. The 17 species that we have described in previous publications are cited but descriptions are not repeated. We are unable to differentiate the larvae of the 10 subgenera studied: the differences among the larvae of the 38 species are not congruent with adult differences and they are not of subgeneric magnitude. We have also stressed the homogeneity of the genera of the tribe Camponotini. The Old World genus Polyrhachis and the cosmopolitan Camponotus both belong to the tribe Camponotini, the former has monomorphic workers, while the latter is highly polymor phic. According to Emery's Genera Insectorum Camponotus is the world's largest genus with 618 species, while Polyrhachis is third with 359 species. Wheeler (1922) recognized 36 subgenera in Camponotus but only 12 in Polyrhachis. The 11 species of Polyrhacis described here for the first time are all from Malaysia, thanks to the very generous donation of Dr. Wolfgang Dorow of Johann Wolfgang Goethe
