RATCLIFFE Systematics Research Collections W436 Nebraska Hall, University of Nebraska Lincoln, NE 68588-0514, U.S.A. [email protected] ABSTRACT A comprehensive revision of the genus Hoplopyga Thomson, 1880 is presented. Eighteen species are redescribed, and two new species are described. A key for identification, distribution maps, and images of the 20 species are pro- vided. Hoplopyga ruteri Antoine is removed from the genus and placed in junior synonymy with Macrocranius similis Schürhoff. Lectotypes are designated for Hoplopyga brasiliensis (Gory and Percheron), Hoplopyga corumbana Schürhoff, and Hoplopyga multipunctata (Gory and Percheron). The following new synonymies are established: Hoplopyga lucidiventris (Thomson) is Hoplopyga foeda (Schaum); Hoplopyga spurca (Janson) is Hoplopyga liturata (Olivier); Hoplopyga monacha (Gory and Percheron) and Hoplopyga rubida (Gory and Percheron) are Hoplopyga singularis (Gory and Percheron). Hoplopyga pseudomiliaris Shaughney and Ratcliffe from Guatemala and Hoplopyga riparia Shaughney and Ratcliffe from Peru and Brazil are described as new species. Key Words: taxonomy, nomenclature, scarab beetles, fruit beetles, Neotropics The Cetoniinae (Coleoptera: Scarabaeidae) is an MacLeay (sensu lato) to define species limits. The attractive subfamily of scarab beetles known as the biology of most species remains unknown, and fruit beetles or flower chafers.

Where necessary, corrected names are proposed that comply with the current provisions of the International Code of Nomenclature of Prokaryotes and its Orthography appendix. These lists, as well as updated lists of newly published names of Candidatus taxa with additions and corrections to the current lists to be published periodically in the International Journal of Systematic and Evo- lutionary Microbiology, may serve as the basis for the valid publication of the Candidatus names if and when the current propos- als to expand the type material for naming of prokaryotes to also include gene sequences of yet-uncultivated taxa is accepted by the International Committee on Systematics of Prokaryotes.

Box 339, Bloemfontein 9300, South Africa Invertebrates include more than 80% of all animals, yet they are severely under-represented in studies of southern African diversity. Site biodiversity estimates that do not consider invertebrates, not only omit the greatest part of what they are attempting to measure, but also ignore major contributors to essential ecosystem processes. All available information on spider species distribution in the South African Savanna Biome was compiled. This is the largest biome in the country,occupying over one third of the surface area.A total of 1230 species represented by 381genera and 62 families are known from the biome. The last decade has seen an exponential growth in the knowledge of the group in South Africa, but there certainly are several more species that have to be discovered, and the distribution patterns of those listed are partly unknown. Information is summarized for all quarter degree squares of the biome and reveals considerable inequalities in knowledge. At a large scale the eastern region is much better surveyed than the western parts, but at smaller scales throughout the region, several areas have little information.

Altogether 1049 species of insects belonging to 13 orders and 106 families were collected from the study area. Of these 636 species belonging to 13 orders and 106 families were identified. Out of the 484 species of lepidopterans collected, 401 species belonging to 31 families were identifed. which include 124 butterflies and 277 moths. Among the 105 species of macro hymenopterans collected 84 species belonging to 16 families were identified. The overall diversity index for the study area was 4.763. The overall insect diversity index was significantly higher in the moist deciduous forest (4.835) than that in the teak plantations (4.318). The diversity index for evergreen based on ten months data was 4.509. The overall diversity index varied significantly between years in the study area.

Center U.S. Department of Agriculture, Agricultural Research Service, Invasive Plant Research Laboratory, Fort Lauderdale, Florida, USA PEST STATUS OF WEED Waterlettuce, Pistia stratiotes L., (Fig. 1) is a floating, herbaceous hydrophyte first recorded from Florida during the 18th century (Stuckey and Les, 1984). It forms extensive mats (Fig. 2) capable of blocking navi- gational channels, impeding water flow in irrigation and flood control canals, and disrupting submersed animal and plant communities (Sculthorpe, 1967; Attionu, 1976; Bruner, 1982; Sharma, 1984). Waterlettuce is among the world’s worst weeds (Holm et al., 1977). It has been placed on prohibited Figure 2.

Waterlettuce is a serious weed of rice crops in other countries (Suasa-Ard, 1976), but has not been reported as interfering with production in the United States. It also can interfere with hy- droelectric operations (Napompeth, 1990), but has not done so in the United States. Consequently, di- rect losses attributable to waterlettuce result prima- rily from restricted water flow in irrigation and flood control canals in Florida. Unfortunately, the eco- nomic costs associated with such damage have not been quantified, but federal and state waterlettuce control operations in Florida cost nearly $650,000 annually (Center, 1994).

Plant-feeding insects play an often unappreciated but important role in the dynamics of aquatic and wetland ecosystems. Natural resource managers, scientists, and others working in such ecosystems need to be able to recognize these insects and the damage they cause. This manual provides photographs and descriptions of the life stages and feeding damage of about 50 of the most common native plant-feeding insects and naturalized biological control insects found in aquatic and wetland ecosystems in the United States.
