The longhorned beetle genus Kudekanye (Cerambycidae: Apatophyseinae) new genus and Kudekanye suidafrika new species are described from the lowland fynbos and renosterveld ecosystem of southern Africa. The type species is characterized by large globose eyes with ventral lobes that nearly touch on the gena, dull brownish-yellow body color, five vague costae on each elytron, and antennae that are estimated to be 3.8 times the body length. Additionally, the recently described Afroartelida teunisseni, also in the Apatophyseinae, is recorded for the first time from Swaziland and Zimbabwe.

Annual monitoring surveys for the endangered American burying beetle, Nicrophorus americanus Olivier, have been conducted in south central South Dakota since 1995. The population has been stable in abundance and distribution. Two mark and recapture surveys were conducted in June and August, 2005 in southern Tripp County, South Dakota, U.S.A. Using baited pitfall traps, we captured and marked 168 specimens of N. americanus during 410 trap-nights in June. In August, 323 specimens were captured and marked in 450 trap-nights. We estimated the population size of N. americanus in an area of approximately 220 km². Estimates were obtained using a family of models (program CAPTURE) that incorporate several sources of variability in probability of capture. The June population estimate (±1 SE) was 442 ± 73 and a 95% confidence interval of 333–624 adults. The August population estimate (±1 SE) was 901 ± 117 with a 95% confidence interval of 714–1,177 tenerals and adults combined.

Larvae of Megacerus flabelliger Fåhraeus were found in Venezuela feeding in seeds of Merremia macrocalyx (Ruiz and Pavon) O'Donnell, a convolvulaceous weed about which little is known regarding its natural enemies. In the study locality, M. macrocalyx produces fruits with one to four seeds. The bruchid oviposited more frequently on fruits with multiple seeds but only one seed was attacked, although in some fruits with multiple seeds almost all seeds had eggs. Oviposition occurred most frequently on seeds still on the plant. Only M. flabelliger eggs were noted on the seeds of M. macrocalyx. While on a few seeds there was more than one egg attached, most seeds held only a single egg and only one adult emerged from a seed. Wasps belonging to the families Braconidae, Eupelmidae, Eurytomidae and Eulophidae emerged from seeds not destroyed by the bruchid.

We examined the distribution of adult Buprestidae and Cerambycidae in the Tenderfoot Creek Experimental Forest in the Little Belt Mountains of central Montana, U.S.A., using pan traps and sweep samples on different species of flowering plants. Using several methods during multi-year (2001–2004), summer-long surveys, we documented the presence of adults of three species of Buprestidae and ten Cerambycidae. Pan traps were placed along transects within meadows, unlogged lodgepole pine forests, and in differentially-logged plots initially logged in 1999–2000 and managed by the U.S. Forest Service. Results from pan trap samples support the conclusion that, compared to unlogged plots and meadows, adult buprestids and cerambycids were more abundant in the shelterwood areas after 2001, perhaps because of the greater abundance of decaying wood in the logged areas. Cerambycids, particularly Cosmosalia chrysocoma (Kirby) and Gnathacmaeops pratensis (Laicharting), were also commonly collected on flowers, and were most likely to be found on those with white blossoms and readily accessible nectar and pollen.

Cicindela (Dromochorus) pruinina (Casey) is a flightless tiger beetle that was described by Casey in 1897. Since its description, it has had a diverse nomenclatural history. It occurs from Kansas and central Missouri south through Oklahoma to south Texas. Aspects of the life history are poorly known, and the larval stages have not been described. Collections of live adults from Onaga, Kansas, were transferred to a terrarium, eggs were obtained, and larvae were reared and described. Larvae were similar to other known species of Cicindela L. Notes on habitat and adult behavior were also made.

Thirty-three nests of Gromphas lacordairei Brullé and Ontherus sulcator (Fabricius) were studied at Navarro, Buenos Aires, Argentina. Nests examined in the field and micromorphological studies of brood chambers demonstrate for the first time that G. lacordairei shows delayed provisioning, constructs nests with storage burrows, and makes brood masses with a discrete external wall of soil. These characters place G. lacordairei in Pattern II nesting behavior. Ontherus sulcator constructs either brood balls beneath dung pads by direct provisioning or only feeding burrows. The orientation and structure of the egg chamber is different from those of Ontherus mexicanus Harold.

The Mexican dung beetle species Liatongus monstrosus (Bates) is redescribed and made the type of Attavicinus new genus. The phylogenetic evidence for the creation of this taxon and its biology and close association with the debris piles of the leaf cutter ant, Atta mexicana (Smith), are discussed. Information on the restricted distribution in Jalisco and Michoacán and the biogeography and systematics of this genus and the other New World members of the Oniticellini is also included.

The formerly monotypic genus Panopides Pascoe is revised to include two species from Sulawesi and one from the Philippines. The genus and its type species, P. anticus Pascoe, are redescribed. Panopides philippinicus (Heller) new combination is transferred from Asytesta Pascoe and is also redescribed. Lectotypes are designated for both species. A new species from Central Sulawesi, P. riedeli Setliff new species, is described. All species are diagnosed and illustrated and male characters are described and illustrated for the first time. A new generic group of Indo-Australian crowned weevils is proposed and four genera, Asytesta Pascoe, Cyamomistus Heller, Nothotragopus Zimmerman (new placement), and Panopides placed therein.

The morphology of sternite VIII as well as that of the spermatheca of the females of Dendroctonus frontalis (Zimmermann) and D. mexicanus (Hopkins) is presented, and these structures are proposed, for the first time, as an alternative for the identification of these species. The main characteristic of sternite VIII is the shape and sclerotization of their central ridge, more sclerotized and with better defined borders in D. mexicanus. As for spermathecae, the most useful characteristic is their internal ornamentation which in D. frontalis covers the posterior half of the capsule and has twice as many traverse grooves as in D. mexicanus, where the grooves are more spaced and only cover the posterior third.

We report on one of the largest known occurrence of minor morphological anomalies in adult ground beetles (Coleoptera: Carabidae) in North America. Carabid beetles were caught in pitfall traps in 2006 in ash (Fraxinus spp.)-dominated stands in southeastern Michigan. About 10% and 32% of the trapped individuals and species, respectively, showed morphological anomalies that ranged widely from the presence of tumors, cysts, fossae, misplaced setae, and missing and fused elytral striae to incomplete pronotum. The genus Pterostichus Bonelli had the greatest numbers of anomalies that were present primarily on the elytra, although the head, pronotum, and abdominal sternites were also affected. Within species, Pterostichus melanarius (Illiger), the introduced European carabid beetle, had the greatest numbers of morphological anomalies. Slightly more females than males with anomalies were caught in these forest stands. The occurrence of such high numbers of morphological anomalies in adult beetles across the central hardwood forests is perplexing, and we suggest future studies focus on elucidating its causes within this forested landscape.

The cave-associated Pselaphinae of Indiana are listed with their collection data, and a key is provided to the species of Batrisini. Batrisodes krekeleri Park 1960 is placed as a junior synonym of B. hairstoni Park 1947, and both sexes are redescribed. This uncommonly collected species has been taken only at cave entrances in southeastern Indiana, and its ecology is briefly discussed.

Morphological changes in the reproductive organs and neuroendocrine centers of Eurysternus mexicanus Harold males and females of known age and behavior were studied in the laboratory. In females, ovarian activity was related to morphophysiological changes in neuroendocrine centers; in males, similar changes influenced glandular reservoirs during several stages: prenesting, copulation, nesting, and infanticide. In females, the activity of the pars intercerebralis and corpus allatum during prenesting is related to vitellogenesis and sexual maturity; during nesting, it is linked to oviposition and nest care. In males, both these periods are characterized by modifications in the neuroendocrine centers relating to the synthesis of accessory gland secretions that accumulate in glandular reservoirs until copulation takes place. Larvicide was committed only during provisional nest care–by 88% of females after copulation during the early days of nest care and by 66% of copulated females when brood balls had 2nd and 3rd instar larvae. Twenty-two percent of males committed larvicide before copulating with the females that were caring for provisional nests. The changes noted in neuroendocrine centers and gonads during larvicide are the same as those related to copulation. Factors that may lead to larvicide could not be determined, as its physiological regulation must be extremely complex.

The species of the Oriental and Papuasian genus Cryptoxyleborus Schedl in the Scolytine tribe Xyleborini are reviewed. Two new species, C. cuneatus and C. mawdsleyi are described from Brunei Darussalam. The following new synonymy is proposed: Cryptoxyleborus oxyurus Schedl ( = Cryptoxyleborus shoreae Browne syn.n.), Cryptoxyleborus vestigator (Schedl) ( = Platypus goilalae Schedl syn.n.). The following new combinations are given: Cryptoxyleborus acutus (Schedl) comb.n., Cryptoxyleborus percuneolus (Schedl) comb.n., both from Xyleborus; Microperus nanus (Browne) comb.n. from Cryptoxyleborus. A lectotype is designated for C. percuneolus, and the previously unknown male is described. A key is given to 18 species currently included in the genus, and new distributional records for many species. All species of Cryptoxyleborus are ambrosia beetles associated with dead or dying trees of the family Dipterocarpaceae, but are not of significant economic importance.

The third instar larva and pupa of Ancognatha scarabaeoides Erichson are described for the first time, and adults of both sexes are redescribed, to support the study of the soil white grub species assemblage in Colombia. Data on the phenology and distribution of A. scarabaeoides are included for some localities in the departments of Antioquia, Caldas and Tolima, Colombia, where it was found associated with potato fields.

The genus Cryptorhynchus Illiger 1807 is reviewed for the United States and Canada. Five species are recognized; C. fuscatus LeConte, C. helvus LeConte, C. obliquus Say, resurrected combination, C. lapathi (Linnaeus) and C. tristis LeConte. Sternochetus woodruffi Sleeper is a new junior synonym of C. helvus. Cryptorhynchus minutissimus LeConte is transferred provisionally to Acalles Schoenherr near Acalles sablensis Blatchley as Acalles minutissimus (LeConte), new combination. A neotype is designated for C. obliquus (Say). A key to the five species is presented along with brief diagnoses, and summaries of natural history and distribution.
