Abstract
  • A taxonomic study was made on the genera Rhynchophorus and Dynamis of the weevil family Curculionidae which includes all of the species known to occur in the world. The bibliography lists all the important papers published to date on the taxonomy and bionomics of these weevils. A full synonymy is given for each species with the appropriate literature cited in the bibliography. Eight species of Rhynchophorus--barbirostris, glabrirostris, indostanus, kaupi, montrouzieri, pascha, rubrocinctus, signaticollis - and two species of Dynamis--politus, germari--are placed in synonymy. Keys to genera, species, and known pupae and larvae are given. A subgenus Rhynchodynamus Heller is elevated to generic rank. Twenty-two species are treated, twelve of which redescribed completely and ten of which are described as new. Of these 22 species, filirostris belonged to Rhynchodynamis, 10 belonged to Rhynchophorus, two of which, distinctus and ritcheri, are new; 11 belonged to Dynamis, eight of which, artorntipae, callirostris, coracinus, palmiphilus, perplexus, perryi, rebeccae, and rockefelleri, are new. A brief discussion of the biology, morphology, immature stages, distribution and economic importance of these weevils is included. Distribution maps of genera and species are given as well as 743 figures illustrating characters of adults and immature stages.
