Lissotes krakei Bartolozzi, de Keyzer, and Zilioli, new species, is described from the Victorian Alps of Australia. The new taxon is closely related to Lissotes darlingtoni Benesh, 1943 and Lissotes furcicornis Westwood, 1871 from which it differs in the shape of the male head and mandibles, the female canthus, and the punctation and shape of the head and pronotum of both sexes. An updated list of the species in Lissotes Westwood inhabiting mainland Australia is given, and a key for their identification is included.

Natural history observations are presented for 15 species of leaf-mining chrysomelid beetles, including previously unrecorded details of mine characteristics as well as oviposition and feeding habits of adults. New larval host records include Ceanothus velutinus Douglas ex Hook. (Rhamnaceae) for Baliosus californicus (Horn); Betula lenta L. (Betulaceae), Castanea dentata (Marshall) Borkh., and Quercus velutina Lam. (Fagaceae) for Baliosus nervosus (Panzer); Abutilon Mill. (Malvaceae) for Stenopodius texanus Schaeffer; Ambrosia artemisiifolia L. (Asteraceae) for Sumitrosis inaequalis (Weber); Celastrus orbiculatus Thunb. (Celastraceae) for Sumitrosis rosea (Weber); and Fallopia scandens (L.) Holub (Polygonaceae) for Mantura floridana Crotch.

The monotyopic genera Astroscara Schürhoff, 1937, Chiriquibia Bates, 1889, Hadrosticta Kraatz, 1892, Jansonia Schürhoff, 1937 (revised status), Macrocranius Schürhoff, 1935, and Tiarocera Burmeister, 1842 (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini) are reviewed. Redescriptions, diagnoses, distributions, and illustrations of the species are provided. A type species for Tiarocera is designated.

The distribution of Rhyssemus puncticollis Brown, 1929 in Poland and Latvia, new country records, is presented. Besides 26 localities in northern and central Poland, one Latvian locality is known. The beetle frequently and abundantly inhabits lawns in and around large urban agglomerations, as well as sandy river banks and adjacent pastures. Larvae of this thermophilous, psammophilous, saprophagous species feed upon the organic matter of the upper soil layer of plant origin. We describe the particularly useful diagnostic differences in external morphology between R. puncticollis and Rhyssemus germanus (L., 1767).

A new genus and a new species of Dicrepidiina, Toctoc Casari and Toctoc asymmetricus Casari, from Brazil (Maranhão) are described and illustrated. A comparison with other genera of Dicrepidiina is presented.

This treatise deals with the new genera Akonesis Opitz, new genus, Antennosus Opitz, new genus, Crusbatus Opitz, new genus, and Diutius Opitz, new genus. Two new species are described: Crusbatus spinosus Opitz, new species and Diutius pallidus Opitz, new species. A lectotype is designated for Akonesis pictipennis (Spinola). In addition to descriptions of taxa, a key to the genera and species and discussions of natural history and evolutionary relationships are provided. Eighteen characters were evaluated phylogenetically and analyzed with WINCLADA, in coordination with NONA, to generate two well-supported phylogenetic trees. It is postulated that the ancestor of the genera evolved in South America, with one species dispersal into the more eastern Panamanian terrain. The distribution of most species coincides with Quaternary forest refugia and South American clerofaunas.

Libotrechus duanensis Lin and Tian, new species, the second species of the cavernicolous carabid genus Libotrechus Uéno, 1998, is described from a limestone cave in Du'an Xian of northern Guangxi province in southern China. Based on the morphological character states of L. duanensis, several supplemental diagnostic characters for the genus Libotrechus are noted. In addition, new distributional records of Libotrechus nishikawai Uéno, 1998 in the Mulun Karst of northernmost Guangxi, together with a distributional map for the genus, is provided.

Sphenophorus spangleri Anderson, new species, from Mazatlán, Sinaloa, Mexico is described. The species is very similar to Sphenophorus lineatus Champion and Sphenophorus quadrivittatus Gyllenhal, two similarly colored Mexican species that have a red pronotum with three longitudinal black stripes. The new species is distinguished by its larger body size, eyes narrowly separated in dorsal view, antennal club with the apical pilose portion very small, proportionally narrow body form, very long, slender, linear tarsal articles which are not expanded laterally, and the pygidium with deep, dense, subconfluent punctures limited to the apical portion. Illustrations comparing the three species and a key to the three species are provided. A lectotype is designated for Sphenophorus lineatus Champion.

A survey of the modern carabid fauna of Maine has shown that the fauna consists of 425 documented species, 14 more than previously documented for the Maine fauna in the latest catalog for the family in North America or in the most recent checklist on the state beetle fauna. New state records are Agonum cupreum Dejean, Amara anthobia Villa and Villa, Anisodactylus laetus Dejean, Bembidion intermedium Kirby, Bembidion sejunctum sejunctum Casey, Brachinus vulcanoides Erwin, Diplocheila impressicollis Dejean, Elaphropus dolosus LeConte, Lebia grandis Hentz, Myas coracinus Say, Olisthopus micans LeConte, Panagaeus fasciatus Say, Pentagonica picticornis Bates, and Tachyta parvicornis Notman. The record for B. sejunctum sejunctum is the first for the species in the eastern United States. A recent record for Omophron labiatum (F.) in the state could not be substantiated by any specimen. Notes on biology are presented for species for which that knowledge exists. Distributions are presented for all taxa based on standard biophysical regions for the state and the knowledge of those distributions; distribution maps are presented for all species for which township records are known and for which we have specimen records in our database. Work on better defining the current distributional limits is ongoing. Several adventive European taxa have already exhibited very rapid dispersal across the state.

A total of 17 species of Scarabaeidae (1,288 individuals) and nine species of Hydrophilidae (482 individuals) were sampled from a cattle and sheep farm in southeastern Michigan between March 2012 and May 2013. Seven of these species are native, while 19 species are of European origin. Despite the closeness of the farms (730 m), Otophorus haemorrhoidalis (L.), Sphaeridium lunatum F., and Sphaeridium scarabaeoides (L.) were found significantly more frequently on the cattle farm, whereas Labarrus pseudolividus (Balthasar), Oscarinus rusicola (Melsheimer), and Blackburneus stercorosus (Melsheimer) were found significantly more frequently on the sheep farm. The highest abundances of beetles were encountered between May and November and correlated with temperatures above 10°C. Eleven species occurred only from spring to summer, eight species occurred from summer until autumn, and six species showed a split pattern of spring to early summer, absence during summer, and a second occurrence in autumn. No beetles were found between 4 January and 16 April 2013. To further understand the invasive potential of adventive dung beetle species, seasonal patterns of species within the three groups were compared to seasonal patterns of the same species at more northern, more southern, and European locations and to predictions arising from climatic differences between these latitudes.

Tritoma subbasalis (Reitter, 1896) is known in Poland from a few localities in the northern and southeastern regions. Nine new Polish localities are provided. Tritoma subbasalis as a saproxylic beetle can survive only in old forests rich in deadwood, growing in fertile, humid stands. It develops on fungi infesting both living trees and deadwood. Host fungi belong to the genera Daedaleopsis J. Schröt., Trametes Fr., Lenzites Fr., and Inonotus P. Karst. Tritoma subbasalis is an indicator of quasi-natural forests, and may facilitate the recognition of such forest complexes in Poland.
