An annotated list is presented for 81 species of lady beetles (Coccinellidae: Coleoptera) that occur in the state of Iowa, U.S.A., based on literature searches and a review of over 3500 specimens in institutional and private collections. The list includes new state records for Scymnus tenebrosus Mulsant, Diomus debilis (LeConte), Hyperaspis lateralis Mulsant, Hyperaspis deludens Gordon, Epilachna borealis (F.), and Subcoccinella vigintiquatuorpunctata (L.), as well as county records for the non-native species, Harmonia axyridis (Pallas). Collection records are discussed for Nephaspis oculatus (Blatchley), Hyperaspidius militaris (LeConte), Coccinella californica Mannerheim, and S. vigintiquatuorpunctata, which have Iowa records that are disjunct from their larger geographic distributions in North America. I also discuss collection records and the need for additional collecting of coccinellids in Iowa, especially Adalia bipunctata (Schneider), Coccinella transversoguttata richardsoni Brown, and Coccinella novemnotata Herbst, which were once common and widespread but have declined drastically over much of North America, including Iowa.

Recent extensive and intensive field work by the team of M. A. Ivie on the Lesser Antillean island of Montserrat suggests that a mean of 827 beetle species may be expected on that island. This datum makes possible the generation of hypotheses of the probable beetle species diversity on other islands of the Lesser Antilles as a function of the areas of the islands. Figures are given for the presently known, estimated total, and estimated number of unknown species for each principal island. This predicts that many hundreds (if not thousands) of beetle species remain to be discovered. This is of importance to land management and conservation interests on these rapidly changing and ecologically fragile islands.

Distribution and habitat information are provided for 1578 adult specimens of Odonata representing 127 species in 70 genera and 16 families that were collected from 143 locations throughout Thailand. Of the species collected, 25 (20%) were represented by a single specimen, and 40 (31%) were collected from a single location. Collections were made at 49 lentic and 85 lotic sites, and an average of 6.9 and 6.6 species were collected at each site in each habitat, respectively.

Megatharsis buckleyi Waterhouse, 1891 is newly recorded from Brazil, extending its distributional range beyond Ecuador and Peru. A further new provincial record from Ecuador is presented in detail, and the species’ distribution and habitat is discussed. Color variation within the species, with a possible geographic correlation, is reported here for the first time.

Two samples of the chordeumatidan family Rhiscosomididae (Rhiscosomides mineri Silvestri, 1909) and 35 of the Conotylidae establish these taxa in the Alexander Archipelago and continental parts of the Alaskan Panhandle, USA, and northern coastal British Columbia (BC), Canada. Rhiscosomides mineri is also recorded from southwestern BC and, for the first time, from Washington State, USA. Two conotylids were recovered, a juvenile male of ?Bollmanella Chamberlin, 1941, and 3 males and 33 females of a possibly parthenogenetic form of Taiyutyla Chamberlin, 1952, conforming generally to T. shawi and T. lupus, both by Shear, 2004, on Vancouver Island. Diplopoda are predicted to inhabit the southern Yukon Territory.

I provide the first record for the recently described hangingfly, Bittacus monastyrskiyi Bicha, 2007, from Há Tay Province (Ba Vi National Park), Vietnam, along with new seasonal, altitudinal, and habitat data. This is the only described species of bittacid from Vietnam, and this new record extends its range 100 km northnorthwest from its type locality in Cuc Phuong National Park, Thanh Hoa Province.

The Southeast Asian scarab beetle genus Peltonotus Burmeister (Scarabaeidae: Dynastinae) is associated with aroid flowers and possesses a unique, articulated maxillary tooth. We describe five new species of Peltonotus: P. animus and P. cybele from Sumatra, P. favonius from Vietnam, P. mushiyaus from Borneo, and P. tigerus from Thailand. The circumscription of P. karubei Muramoto is broadened to include new color variation, and the body size range for the genus is increased with Peltonotus mushiyaus, n. sp., now being the smallest member of the genus. We provide an amended key to species, distribution maps, diagnoses and accompanying comparative images, and discuss classification of the genus within the Scarabaeidae.
