Evolutionary trends within the major groups are also discussed. The following (i) adult and (ii) larval characters are discussed: (i) antennal segments, antennal sensilla, ocular canthus, ommatidium structure, epipharynx, mandibles, maxillae, labium, tentorium, trochantin, coxal cavities, mesothoracic spiracles, wing venation, metendosternite, empodium, abdominal sternites, abdominal spiracles, male genitalia, female genitalia, ovarioles, karyotype, central nervous system, spermatozoan number and malpighian tubules; (ii) antennae, frontoclypeal suture, lateral ocelli (stemmata), labial palpi, maxillae, maxillary palpi, maxillary/mandibular stridulatory areas, labrum, epipharyngeal tormae, legs, stridulatory apparatus, spiracles, abdominal apex and central nervous system.     

Invertebrate fauna of wastewater ponds in southeastern Idaho

Water column invertebrates were sampled with 3.8-L activity traps in 15 sewage, industrial, and radioactive wastewater ponds at the Idaho National Engineering Laboratory in southeastern Idaho. One collection was made per pond, per month, during all months the ponds were ice-free from June 1990 through July 1991. Arsenic, barium, boron, lead, selenium, and mercury were detected in ponds. Sewage ponds generally had higher nitrogen and phosphorus levels than industrial and radioactive ponds. Of the 30 aquatic invertebrate taxa collected, the most ubiquitous were Rotifera, Daphnidea, Eucopepdoa, Ostracoda, Acari, Baetidae, Corixidae, Notonectidiae, Dytiscidae, and Chironomidae. Activity trap samples from sewage ponds contained more Rotifere, Daphnidae, and Notonectide, whereas industrial ponds yielded more Chydoridae, Acari, and Baetidae. Numbers of Oligochaeta, Eucopepoda, Ostracoda, Corixidae, Dytiscidae, and Chironomidae collected were not significantly different between sewage and industrial ponds. Compared with natural systems, these ponds had fewer taxa, but a greater number of individuals of most taxa. The high number of invertebrates collected is attributed to the lack of fish in wastewater ponds and the high levels of nitrogen and phosphorus, particularly in sewage ponds.     

Nomenclatural changes in Scolytidae and Platypodidae (Coleoptera)

New synonymy in Scolytidae includes Cryphalus piceae (Ratzeburg, 1837) (= Cryphalus subdepressus Eggers, 1940), Gnathotrupes longiusculus (Schedl, 1951) (= Gnathotrupes ciliatus Schedl, 1975), Hypothenemus eruditus Westwood (= Stephanoderes communis Schaufuss, 1891). In Platypodidae the new name Platypus abruptifer is proposed as a replacement for the junior homonym Platypus abruptus Browne, 1986; type-species designations are proposed for the genus group names Scutopygus Nunberg, 1966, Pygodolius Nunberg, 1966, Mixopygus Nunberg, 1966, Mesopygus Nunberg, 1966, Asetus Nunberg, 1958, Stenoplatypus Strohmeyer, 1914, Platypinus Schedl, 1939, Platyscapus Schedl, 1939, Treptoplatypus Schedl, 1939, Tesseroplatypus Schedl, 1935; previously unpublished specific synonymy is presented for Crossotarsus externedentatus (Fairmaire, 1849) (= Diapus talurae Stebbing, 1906), Crossotarsus terminatus Chapuis, 1865 (= Crossotarsus nicobaricus Beeson, 1937), Platypus abditus Schedl, 1936 (= Platypus transitus Schedl, 1978), Platypus rugosifrons Schedl, 1933 (= Platypus pretiosus Schedl, 1961), Platypus tiriosensis Reichardt, 1965 (= Platypus schedli Wood, 1966), Treptoplatypus multiporus Schedl, 1968 (= Playtpus fastuosus Schedl, 1969).     

Revision of Bonesioides Laboissière, 1925 (Coleoptera; Chrysomelidae; Galerucinae) from continental Africa

Bonesioides Laboissière, 1925, Galerucinae endemic to Tropical Africa is revised. This group is characterized by the metallic coloration of the entire dorsum or at least parts of it, the prothorax is moderately trapezoidal, posteriorly enlarged, and lacks any pronotal depressions, the basi-metatarsus is moderately elongated, pronotal coxal cavities are open behind, and distinctly shaped male genitalia. Most metallic-coloured species originally described in Barombiella Laboissière, 1931a are herein transferred to Bonesioides. For each species drawings of the habitus, basal antennal articles, spermatheca and median lobe are given. Species distributions are illustrated in maps, and an identification key is given. In a phylogenetic analysis including other Afrotropical Galerucinae with elongated basi-metatarsi, 'Monoleptites' is found to be a non-monophyletic group. Bonesioides now includes 21 species as follows (including new taxonomical changes): Bonesioides coerulea (Allard, 1889); Bonesioides purpureipennis Laboissière, 1925 = Bonesioides speciosa Laboissière, 1937, syn. nov.; Bonesioides dimidiata Laboissière, 1937; Bonesioides kirschi (Jacoby, 1899), comb. nov. = Monolepta munroi Bryant, 1931, syn. nov., = Barombia lesnei Laboissière, 1931b, syn. nov., = Barombiella babaulti Laboissière, 1939, syn. nov.; Bonesioides barombiensis (Jacoby, 1903), comb. nov. = Barombiella graciosa Laboissière, 1941, syn. nov.; Bonesioides caerulea (Jacoby, 1903), comb. nov.; Bonesioides virens (Weise, 1913), comb. nov. = Barombiella opalina Laboissière, 1940, syn. nov., = Monolepta ruwensorica Bryant, 1952, syn. nov.; Bonesioides laboissierei nom. nov.

Local floras, that is, plant lists for relatively small areas, are widely scattered, often unpublished, and difficult to locate. Over 100 local floras from the southwestern United States (Arizona, Colorado, Nevada, New Mexico, and Utah) are listed and briefly annotated.     

New species of American Corthylus (Coleoptera: Scolytidae)

A search for characters to make the generic classification of Platypodidae more nearly objective resulted in the discovery of new anatomical features that appear to reflect patterns in phylogeny for this family. The Platypodidae are members of the Curculionoidea and are very closely allied to Scolytidae. Three subfamilies of Platypodidae are recognized: (1) Coptonotinae, containing Coptonotini ( Coptonotus Chapuis, Protohylastes Wood, Scolytotarsus Schedl), Mecopelmini ( Mecopelmus Blackman, Protoplatypus Wood), and Schedlarini ( Schedlarius Wood [= Chapuisia Dugès]); (2) Tesserocerinae, containing Diapodini ( Diapus Chapuis, Genyocerus Motschulsky [= Diacavus Schedl], and Tesseroccrini ( Platytarsulus Schedl, Notoplatypus Lea, Tesserocranulus Schedl, Tesserocerus Saunders [= Damicerus Spinola, Tesseroplatypus Schedl, Tesserocephalus Schedl]), Spathidicerus Chapuis, Periommatus Chapuis [= Asetus Nunberg, Setanus Nunberg], Chaetastus Nunberg [= Symmerus Chapuis], Cenocephalus Chapuis, and Mitosoma Chapuis [= Platypicerus Nunberg, Coecephalonus Schedl]); and (3) Platypodinae, containing Platypodini ( Platypus Herbst [= Cylindra Illiger, Stenoplatypus Strohmeyer, Platypinus Schedl, Austroplatypus Browne], Treptoplatypus Schedl, Crossotarsus Chapuis, Trachyostus Schedl, Neotrachyostus Browne, Platyscapulus Schedl [= Platyscapus Schedl, Costaroplatus Nunberg], Baiocis Browne, Cylindropalpus Strohmeyer, Triozastus Schedl, Mesoplatypus Strohmeyer, Doliopygus Schedl [= Scutopygus Nunberg, Pygodolius Nunberg, Mixopygus Nunberg, Mesopygus Nunberg], and 11 genera named as new to science derived from the genus Platypus of Schedl 1972. The following are new genera and their type-species: Peroplatypus (for Platypus truncatipennis Schedl), Dinoplatypus (for Platypus cupulatus Chapuis), Myoplatypus (for Bostrichus or Paltypus flavicornis Fabricius), Oxoplatypus (for Scolytus or Platypus quadridentatus Olivier), Platyphysus (for Platypus obtusus Chapuis), Megaplatypus (for Platypus dentatus Dalman), Euplatypus (for Bostrichus or Platypus parallelus Fabricius), Epiplatypus (for Platypus desceptor Wood), and Teloplatypus (for Platypus concinnus Blandford). The archaic ""sektionen"" used by Schedl in his 1972 classification of this family are eliminated. A key for the identification of genera, a discussion of characters, and remarks on phylogeny are included.

Type material in the University Museum,Oxford, of bees described by Comte Amédée Lepeletier de Saint-Fargeau and Pierre André Latreille (Hymenoptera: Apoidea)

The composition, condition and history of the Latreille-Dejean-Lepeletier collection (the so-called ‘Latreille Collection’) in the Hope Entomological Collections, University Museum, Oxford, are outlined. The type material of certain nominal species of Anthophora Latreille, 1803, Macrocera Latreille, 1810 [nec Meigen, 1803, = Tetralonia Spinola, 1839] and Dufourea Lepeletier, 1841, described by Lepeletier from his personal collection and from the collection of Comte Dejean is reviewed. The type material of certain nominal species of Anthidium Fabricius, 1804, and Panurgus Panzer, 1806, described by Latreille from his own collection is reviewed.     

Wildlife distribution and abundance on the Utah Oil Shale Tracts, 1975-1984

Distribution and abundance of 215 amphibians, reptiles, birds, and mammals were monitored for 10 years on Utah's Oil Shale Tracts using line transects, mist netting, and live trapping. Wildlife monitoring was conducted in four major vegetation types and during all seasons to establish a quantitative baseline for use in impact identification during oil shale mining. Habitat preferences were established for many species in cold desert vegetation of two types of desert shrub, and juniper and riparian woodlands. Seasonal, annual, and habitat distribution of each class demonstrated a variety of adaptive responses to environmental variables. The most important environmental variables, that is, those factors resulting in a predictable change in wildlife populations, were, in descending order: weather, food resource, shelter, and competition.     

New species and records of Asellota from the Indian Ocean (Crustacea: Peracarida: Isopoda)

In this study of asellote Isopoda from the Indian Ocean, 29 species in 11 genera and seven families are recorded. Twenty-one species are described as new: family Gnathostenetroididae, Maresiella aldabrana ; family Janiridae, Carpias mossambica ; family Joeropsidae, Joeropsis algensis, J. arpedes, J. dimorpha, J. hamatilis, J. lentigo, J. pentagona, J. pleurion ; family Pleurocopidae, Pleurocope wilsoni ; family Pseudojaniridae, Pseudojanira meganesus ; family Santiidae, Santia spicata, S. urospinosa ; family Stenetriidae, Hansenium aldabrae, H. expansa, H. remocarpus ; Mizothenar serratum, Stenetrium assumentum, S. quinquedens, S. zanzibarica, Stenobermuda brucei. The first record of the family Pleurocopidae (Pleurocope wilsoni) and the genus Mizothenar (family Stenetriidae) from the Indian Ocean are included. Diagnoses of the genera and species are provided, and keys to the Indian Ocean species of most of the genera. The material comes primarily from Aldabra Atoll, the granitic Seychelles islands, Zanzibar Island, the Comoro Islands, and Phuket in Thailand. A few samples are from material of the International Indian Ocean Expedition carried out in the mid-1960s.     

Natural variability of vegetation, soils, and physiography in the bristlecone pine forest of the Rocky Mountains

Pinus aristata Engelm. forest vegetation in Colorado was studied to determine vegetation composition and the relationship between vegetation and environment. Species percent cover, tree size class, and environmental variables were recorded for 49 plots. Previously collected data for 4 plots form New Mexico were included. Environmental variables included latitude, longitude, elevation, slope, aspect, topographic position, parent material, percent rock cover, mean rock size, litter depth, estimated plot age class, and evidence of anthropogenic disturbance. Soils were analyzed for texture, depth, and percent carbon and nitrogen. Pinus aristata foliage was analyzed for percent nitrogen and phosphorus. Direct and indirect gradient analyses (CANOCO) were used to determine environmental factors associated with community composition. Vegetation in P. aristata forests is influenced primarily by elevation and soil pH. Substrate, soil texture, topographic position, and geographic location are secondary factors. Six plant associations were identified using cluster analysis (listed in an elevational sequence from low to high): Pinus aristata/ Festuca arizonica Vasey, Pinus aristata / Festuca thurberi Vasey, Pinus aristata / Juniperus communis L., Pinus aristata / Vaccinium myrtilus L., Pinus aristata / Ribes montigenum McClatchie, and Pinus aristata / Trifolium dasyphyllum Torr. & Gray.     

A revision of Micropodarke (Psamathini,Hesionidae, Polychaeta)

Micropodarke Okuda, (Psamathini, Hesionidae, Polychaeta) is revised based on examination of all available types, other museum specimens, and a large number of newly collected specimens from Japan, Hong Kong, Papua New Guinea, Australia, New Caledonia, California, the west coast of Canada, and the Red Sea. The previous synonymy of Micropodarke amemiyai Okuda, with M. dubia (Hessle, ) is substantiated, and M. trilobata Hartmann‐Schröder, is newly synonymized with M. dubia, leaving Micropodarke monotypic. A lectotype is selected for M. dubia. Micropodarke dubia is identified by the apomorphies of a proboscis diaphragm, segmental ventral adhesive papillae, distally nobbed and slightly curved neuroaciculae, and median neurochaetae with few, basally situated prolonged teeth (“spurs”), with abrupt transition to the following, much shorter teeth. Micropodarke dubia has a main distribution in the tropical and warm temperate Indo‐Pacific region, and appears to be absent from the Atlantic Ocean.     

Diatom flora of Cowboy Hot Spring, Mono County, California

The diatom flora of Cowboy Hot Spring, Mono County, California, was studied. Two habitats, one at 37C and one at 41C, were examined. Fifty-six taxa were identified from our samples. These taxa were mostly broadly distributed forms, and no endemic species were encountered. The dominant taxon was Nitzschia frustulum, followed by Achnanthes gibberula, Achnanthes exigua, Nitzschia hantzschiana , and Navicula cincta .
