The Anthonomus juniperinus group, with descriptions of two new species (Coleoptera: Curculionidae)
(2010)
The Anthonomus juniperinus (Sanborn) species group is defined and two new species, Anthonomus sanborni, new species, and A. rileyi new species, from the United States are described, keyed and illustrated. The three species of the group are associated with the plant genus Juniperus and the larvae of A. juniperinus are known to develop in fungal galls of Gymnosporangium spp. as well as fruits of the Eastern redcedar, Juniperus virginiana L. The biology of the group and its taxonomic relationships to other species of Anthonomus Germar are also discussed.

The fauna of Phanaeini of the northeast of Brazil was investigated through fieldwork in the States of Ceará, Maranhão and Piauí, and through study of preserved material from other states. Seven species of Phanaeini are newly recorded from these three states. Of these, two species are also new records for the northeast region: Phanaeus melibaeus Blanchard and an unidentified Dendropaemon Perty species. A total of 13 new state records are given for eight of the 15 species of Phanaeini recorded from the northeast to date, including three new state genus records. A key is provided for identification of all species. Detailed distributional information is presented together with habitat and bait preferences and other ecological data for each species. The diversity and distribution of the tribe in the northeast is discussed in the context of regional biotopes and wider geographic ranges. The fauna is shown to be more diverse than previously believed, containing both endemic and widespread elements occurring in species assemblages that differ according to habitat type and elevation, leading to substantial complementarity of diversity amongst the main biogeographic provinces and biotopes of the region.
0117
Four new species of Cydistomyia Taylor from New Guinea, C. missimiensis, C. madangiensis, C. waigani, and C. moresbyensis, are described and figured. A revised key to the females of New Guinea Cydistomyia and New Guinea collection records for 57 additional species of Tabanidae are provided. A table with the approximate longitudes and latitudes of all but one locality listed is provided.

Hiltonius carpinus carpinus Chamberlin, 1943 (Spirobolida: Spirobolidae), is authoritatively recorded from the United States for the first time; it is known only from southern/southeastern Arizona but should be expected in adjoining counties of New Mexico. The northernmost locality is the Pinaleno Mountains, Graham County, and its distribution extends to southern Mexico; the other subspecies, H. c. vulcan (Chamberlin, 1953), occurs in Guatemala. The range of H. c. carpinus includes the type locality of the enigmatic H. fossulifer (Pocock, 1908), lending credence to prior suggestions that the names are synonymous. Three new Mexican states – Durango, Jalisco, and Nuevo León – are documented for H. c. carpinus.
0115
New species are described in the tribe Piezocerini: Gorybia rondonia sp. nov. from Brazil (Rondônia) and G. bahiensis sp. nov. from Brazil (Bahia); in the tribe Hexoplonini: Calycibidion rubricolle sp. nov. from Brazil (Bahia); in the tribe Ibidionini, Tropidina: Tropidion argentina sp. nov. from Argentina (La Rioja) and T. boliviensis sp. nov. from Bolivia (Santa Cruz); in the tribe Rhinotragini: Ommata (Ommata) albitarsis sp. nov. from Brazil (Rondônia); and in the tribe Rhopalophorini: Cosmisoma viridescens sp. nov. from Brazil (Bahia). To validate the tribal names, Hexoplon Thomson, 1864 and Tropidion Thomson, 1867, are here designated type genera of Hexoplonini and Tropidiina, respectively.
0114
Ten species of antlions are confirmed as present in Paraguay and seven additional species are suspected to be present there. All of the species are found also in Argentina and Brazil except for Eremoleon pulchra (Esben- Petersen) which is endemic to Paraguay. A key to the adults is provided as well as distributional data for Paraguay with two new country records (Ameromyia dimidiata Navás and Austroleon dispar (Banks)).

A new species of anamorphine endomychid, Micropsephodes bahamaensis Shockley is described from a small series of 3 specimens collected on North Andros Island in the Bahamas. Besides being the only species known from the Bahamas, M. bahamaensis is readily recognizable from its congeners based on its much larger size, more elongate habitus and features of the galeae and maxillary palpomere IV. Keys to the known species of Micropsephodes and to the adults of the genera of Anamorphinae that occur in the Western Hemisphere are provided.

The checkered beetle Aphelochroa sanguinalis (Westwood) (Coleoptera: Cleridae) is found in savanna and woodland ecosystems of southern and eastern Africa. During surveys for insect floral visitors in the Skukuza Ranger District of Kruger National Park, South Africa, we encountered adults of Aphelochroa sanguinalis on flowers of two tree species, Acacia grandicornuta Gerstner and Acacia tortilis (Forsskal) Hayne (Fabaceae). These two tree species flower in the early rainy season (November-December) and have small white flowers in small round ball-shaped clusters. Adults of phelochroa sanguinalis were not found on flowers of 14 other tree species with different floral structures which were flowering at the same time as Acacia grandicornuta and Acacia tortilis. Predatory, reproductive, and defensive behaviors (including the presence of a chemical defense) are described for Aphelochroa sanguinalis based on field and laboratory observations.

Adults, and in some species larvae, of several members of Belonuchus Nordmann (Coleoptera: Staphylinidae: Staphylininae) and a few related genera seem to be to various degrees consistently associated with flower bracts of the genus Heliconia (Zingiberales: Heliconiaceae). They are predators and eat various dipterous and lepidopterous larvae in that habitat. Adults of at least Belonuchus cephalotes (Sharp) and Odontolinus fasciatus Sharp are able to immerse completely in water to capture larvae and/or pupae of mosquitoes (Culicidae). Adults and larvae of Belonuchus satyrus Erichson, and adults of B. cacao Blackwelder and B. rufipennis (F.) were found in water-filled flower bracts of Heliconia bihai (L.) L. in northern, lowland Venezuela. The bracts also contained mosquito larvae and semiaquatic coleopterous (Chrysomelidae: Hispinae), lepidopterous (Crambidae: Pyraustinae) and dipterous (Syrphidae, Stratiomyidae, Psychodidae, Richardiidae) larvae, and Annelida. In feeding trials, B. satyrus adults and larvae did not feed on hispine larvae or annelids, but did feed on all the lepidopterous and dipterous larvae available to them; adults dragged larvae and pupae of the mosquito genus Toxorhynchites Theobald from shallow water and thus seemed to be the top predators of the food pyramid within bracts. Records are compiled of association of Belonuchus and relatives with Heliconia bracts in the neotropics. We correct the names used for Heliconia spp. by earlier entomological authors working in Venezuela. Their ‘Heliconia caribaea Lamarck’ is H. bihai (L.) L. and their ‘H. aurea Rodríguez’ is H. bihai cv. Aurea.

A Caribbean species of Mecidea Dallas, M. longula Stål, apparently established in south Florida, is reported from the United States for the first time. Specimens were first collected in February 2008 in a light trap operated in Miami-Dade County, Florida. Collections in that trap have continued through the present. Searches near the trap location resulted in several specimens being taken from smutgrass, Sporobolus indicus (L.), an exotic grass now established throughout much of the southeastern United States. The three North American species of Mecidea are keyed and illustrated. In addition to the Florida locality, M. longula is reported for the first time from the British Virgin Islands, St. Kitts, St. Martin, and the Turks and Caicos Islands.

Generic reassignment of species in the tribe Cephaloleiini Chapuis, 1875 (Coleoptera: Cassidinae)
(2009)
Thirty-one species of Cephaloleiini are assigned to new genera, creating new combinations: 19 to Parimatidium Spaeth, 10 to Stilpnaspis Weise, and two to Demotispa Baly. Demotispa peruana membrata Uhmann, 1957 is raised to full species status. As the transfer of Cephaloleia limbatum Pic to Demotispa creates a homonymy, the species is renamed Demotispa pici nomen novum.

The published beetle fauna of the island of St. Lucia is summarized. It contains 135 genera, and 175 species in 25 families. Four species are accidentally introduced by human activities. Twenty three species are endemic (restricted) to the island. Twenty seven species on St. Lucia are shared only with other islands of the Lesser Antilles, and 22 species are widespread Antilles endemics. The remaining 56.6% of the fauna is otherwise mostly one which is widely distributed in the Antilles and the Neotropics. This suggests that it is mostly an immigrant fauna originating in the continental Neotropics. Undoubtedly, the actual numbers of species on St. Lucia are many times higher than now reported and may originally have been as high as around 1400 species. Of the St. Lucia species known to occur on other islands, the largest numbers are shared with Guadeloupe (102), St. Vincent (79), and Martinique (55).

With documentation of an unidentifiable adult female and juvenile Tingupidae (Chordeumatida), Kodiak Island, Alaska, becomes the westernmost indigenous diplopod locality in North America including continental islands. The northernmost and most proximate locality, Yakutat, lies ca. 935 mi (1,496 km) to the eastnortheast, while Haines, the type locality of Tingupa tlingitorum Shear and Shelley, some 1,196 mi (1,914 km) in this direction, is the most proximate familial site. Kodiak is also one of the most remote indigenous milliped localities in the Pacific, the most proximate ones to the west and south, Kamchatka, Russia, and the Hawaiian Islands, United States, being over 3,300 mi (5, 280 km) distant. Tingupidae is recorded for the first time from Canada excluding the Queen Charlotte Islands, and geographically remote, ostensibly indigenous records from the North Pacific Ocean and environs are tabulated.
0104
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.

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.

Two species of Xyloryctes occur in the United States: X. jamaicensis (Drury) and X. thestalus Bates. Identification and distribution of these species has long been confused but is reviewed and clarified here. Xyloryctes jamaicensis occurs only in the eastern half of the U.S. and not in the southwestern U.S. as previously thought, while X. thestalus occurs in Guatemala and southern Mexico northwards to the southwestern United States. This hypothesis is corroborated by biogeographical and host plant data. Three new synonyms are listed for X. thestalus: X. faunus Casey 1915, X. hebes Casey 1915, and X. thestalus borealis Endrödi. The decline of Fraxinus spp., the food plant of Xyloryctes species, as a result of damage caused by the introduced emerald ash borer (Agrilus planipennis Fairmaire; Buprestidae) in the United States might portend a similar decline for Xyloryctes species in North America.

Six species of the tribe Oryctini, one species of Agaocephalini, and two species of Dynastini are presently recorded from the Cayo district of western Belize. The following five species are newly recorded from Belize: Heterogomphus mniszechi (Thomson), Strategus longichomperus Ratcliffe, S. jugurtha Burmeister, Spodistes mniszechi (Thomson), and Dynastes hercules (Linnaeus). The following two species are newly recorded from Cayo: Enema endymion Chevrolat and Strategus aloeus (Linnaeus). Biological and distributional comments relating to these records are presented and briefly discussed.

The first New World amber member of the family Lucanidae is described from the Dominican Republic. Its age is presumed to be Miocene (20-30 million YBP). It is also the fourth known amber species, the second Miocene fossil species, the second fossil species in the subfamily Syndesinae, and the first species (fossil or extant) of Lucanidae from the entire Caribbean. It is especially interesting because it is a member of the Australasian genus Syndesus MacLeay. Other such disjunct Dominican amber insect fossils are also discussed.

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.
0095
Novel host records and feeding behaviors are reported for five species in three genera of two cassidine beetle tribes, Hemisphaerotini and Imatidiini, from Ecuador. Carludovica Ruiz and Pav. (Cyclanthaceae) is reported as a new plant family and genus host for two species of Spaethiella Barber and Bridwell. Calathea G. Mey (Marantaceae) is reported as the first host record for Aslamidium capense (Herbst) and Calathea lutea Schult. and Calathea majestica (Linden) H. Kenn. are reported as the first host records for Aslamidium semicirculare (Olivier). Immature stages of Demotispa elaeicola (Aslam) are reported for the first time; larvae are external folivores and both larvae and pupae are solitary and lack exuvio-fecal shields. The adults and larvae of D. elaeicola feed by rasping palm fruits, a rare feeding pattern in Cassidinae.
0094
Geographic variation and subspecific taxonomy of United States populations of the tiger beetle Cicindela obsoleta Say are reviewed. Study of primary types and 1,424 museum specimens indicates that four subspecific entities are present in the U.S., for which the valid names are C. o. obsoleta Say, C. o. santaclarae Bates, C. o. vulturina LeConte, and C. o. neojuvenilis Vogt. All four subspecies are illustrated, including many color variants. ArcView Geographic Information System (GIS) computer software is used to study the distribution of these subspecies in the United States. Cicindela o. obsoleta and C. o. santaclarae are only partially allopatric, with extensive areas in Arizona, New Mexico, and Texas where their distributions overlap. Specimens intermediate in their elytral markings between C. o. obsoleta and C. o. santaclarae are reported from localities in New Mexico and Texas where these two subspecies co-occur. In contrast, C. o. vulturina and C. o. neojuvenilis are largely allopatric and show little intergradation with the C. o. obsoleta - C. o. santaclarae complex. It has been suggested recently that disjunct (but as yet unnamed) populations of C. o. vulturina in Missouri and Arkansas may represent a separate subspecies of C. obsoleta. However, the color and elytral pattern characteristics which have been interpreted as diagnostic features of these disjunct populations are also found in many Texas populations of C. o. vulturina, suggesting that the Arkansas and Missouri populations do not merit recognition as a separate subspecies on the basis of these characters alone.

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.

A taxonomic overview for the fritillary genus Speyeria Scudder (= Argynnis Fabricius) and its placement within the Heliconiinae (Nymphalidae) is presented. Taxonomic accounts, type images, and relevant literature for the 25 subspecies within the Speyeria atlantis (Edwards) and Speyeria hesperis (Edwards) complexes and the 16 nominate Speyeria species are included. Errors in nomenclature are identified, taxonomic, life history, and distributional information are updated, and type locality information is discussed. Images of primary type specimens for all 16 Speyeria species and the 25 subspecies in the atlantis - hesperis complexes appear together in color here for the first time. One new combination of a species-subspecies is created: Speyeria hesperis hanseni Emmel, Emmel, and Matoon, 1998, new combination, which was previously Speyeria atlantis hanseni Emmel, Emmel, and Matoon.

Thirteen species of skippers (six newly described; Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini) from higher elevations of Mexico and Central America are reviewed. These are included in four genera (one newly described), some with proposed new combinations. Onespa Steinhauser, 1974, originally described as monotypic, is shown to include three species in addition to its type species, Onespa nubis Steinhauser, 1974. One of these, Atrytone gala Godman, 1900, that has been misplaced in several genera since its description, represents a new combination. The other two species, distributed in montane habitats in northwestern Mexico and in Costa Rica, are described as new. Buzyges Godman, 1900, distributed in Mexico and Central America and also formerly considered monotypic, is shown to embrace four species. Besides the type species, Buzyges idothea Godman, 1900, two species long placed in Poanes Scudder, 1872, Pamphila rolla Mabille, 1883, and Poanes benito Freeman, 1979, are included as new combinations. Another species, known only from Costa Rica, is described as new. These are united by several superficial characters, but especially by genital morphology of both sexes. Librita Evans, 1955, was described to include three species of which one, Librita raspa Evans, 1955, was subsequently removed. Augiades heras Godman, 1900 is here also removed from Librita and placed in a new genus with three previously undescribed species. This completes the disintegration of Librita, which is now monotypic. The four genera, although exhibiting similarities suggesting potential alliance, differ in their unique combinations of several superficial and genital traits from each other and other hesperiine skippers.

New distribution records for the State of Florida are given for several genera and species of water beetles. These include Dytiscidae: Acilius confusus Bergsten; Dytiscus carolinus Aubé; Matus bicarinatus (Say); Elmidae: Oulimnius nitidulus LeConte; Stenelmis mera Sanderson; S. morsei White; Hydrophilidae: Laccobius minutoides d’Orchymont; Scirtidae: Sarabandus robustus (LeConte); Scirtes oblongus Guérin-Méneville. Additional information is provided on the distribution, morphology and three color forms of S. oblongus which is considered to be a senior synonym of Scirtes sexlineatus Chevrolat and S. interruptus Chevrolat.

We provide new county records for four species of panorpids (Panorpa americana Swederus, Panorpa lugubris Swederus, Panorpa sp. undetermined, and one undescribed species from the Panorpa rufescens Rambur species group) and two species of bittacids (Bittacus pilicornis Westwood, Bittacus punctiger Westwood), and call attention to a previously published county record for another species, Panorpa rufa Gray, in Florida. Additionally, we reject a previously published record for the scorpionfly Panorpa claripennis Hine in Florida, which we overlooked in our 2008 preliminary checklist of Florida mecopterans. The record for P. lugubris in Miami-Dade County is the southernmost record for any panorpid in the continental United States.
0083
The class Diplopoda, represented by the families Spirostreptidae (Spirostreptida) and Paradoxosomatidae (Polydesmida), is recorded from Saudi Arabia for the first time. Archispirostreptus transmarinus Hoffman, 1965 (Spirostreptidae) inhabits the Jabal Al-Hijaz Mountains in the southwest, and the Paradoxosomatidae, represented by an unidentifiable, indigenous female, occurs in a “wadi” in the center of the country. Other Middle Eastern familial records are documented, and occurrences in the Arabian Peninsula are mapped. Males, necessary to identify the paradoxosomatid, may be encountered if samplings are timed to coincide with seasonal rains.

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.
0079
The formerly monotypic weevil genus Platytenes Pascoe (Coleoptera: Curculionidae: Cryptorhynchinae: Cryptorhynchini: Cryptorhynchina) as treated here, includes two commonly encountered and broadly distributed species in the eastern Indo-Australian region. Label data indicate that both species are associated with semicultivated betel palm (Areca catechu L., Arecaceae) and human mediated dispersal is suggested to have influenced their present-day distribution. Herein, we provide a diagnosis for Platytenes and redescribe its type species, P. varius Pascoe. We also describe P. occultus Setliff and Larson, a new species from the Solomon Islands. New host and locality records are provided, including the first records of the genus occurring on Ambon Island, the Bismarck Archipelago, D’Entrecasteaux Islands, and many previously unreported localities on New Guinea. A full bibliography, key to species, and distribution map for the genus are also provided.
0078
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.
0077
The classification of the genus Megalographa Lafontaine and Poole, 1991, is reviewed and the five known species diagnosed. The genus is essentially restricted to the New World, although one species M. biloba (Stephens) is migratory and has occasionally straggled to western Europe. A new species (Megalographa talamanca Lafontaine and Sullivan) endemic to the Talamanca Mountain Range in Costa Rica is described. Adults and genitalia are illustrated.
0076
A taxonomic revision was performed on the New World scarabaeoid genus Aegidinus Arrow (Coleoptera: Scarabaeidae: Orphninae). Twelve new species and three previously described species are included in the revision. Keys to New World genera, species of the genus Aegidinus, and distribution maps are provided. Phylogenetic analyses of the world genera of the Orphninae were conducted using 30 adult, morphological characters from representatives of 13 of the 14 genera and three out-group taxa. The subfamily Orphninae is a strongly supported monophyletic group (bootstrap support 88-90%) with respect to the chosen out-group. Characters that support the Orphninae are: mandibles not sickle shaped, molar surface on the mandibles present, lacinia present, and stridulatory comb present. Separate Old and New World lineages are also supported by the phylogeny, when two genera, Goniorphnus Arrow and Stenosternus Karsch, are excluded from the analysis. The new species described are: Aegidinus cornutus Colby, A. crypticus Colby, A. howdenorum Colby, A. howeae Colby, A. oreibates Colby, A. petrovi Colby, A. simulatus Colby, A. sunidgea Colby, A. teamscaraborum Colby, A. tricornis Colby, A. unicus Colby, and A. venezuelensis Colby.

The New World genus Dysmerus Casey, currently with one valid species, is revised. Lectotypes are designated for two species, Dysmerus caseyi (Grouvelle), new status, and Dysmerus sulcicollis Grouvelle, new status. Both are revived from synonymy with D. basalis Casey. Twelve new species are described: Dysmerus boliviensis Thomas, new species, Dysmerus curvicornis Thomas, new species, Dysmerus genaspinosus Thomas, new species, Dysmerus hamaticornis Thomas, new species, Dysmerus impolitus Thomas, new species, Dysmerus skelleyi Thomas, new species, Dysmerus mexicanus Thomas, new species, Dysmerus monstrosus Thomas, new species, Dysmerus politus Thomas, new species, Dysmerus rondoniensis Thomas, new species, Dysmerus symphilus Thomas, new species, and Dysmerus trinidadensis Thomas, new species. A key to adults of the species and illustrations are provided.

The beetle fauna of the island of Barbados is summarized. It is now known to contain 202 genera, and 254 species (in 40 families), of which 232 are named at the species level. Undoubtedly, the actual numbers of species on Barbados are much higher than now known. Nine species are possibly endemic to the island, 15 have been intentionally introduced, and 51 have probably been accidentally introduced through human activity. The remaining 157 named species may occur naturally as a result of natural over-water dispersal processes. These species mostly have a wide distribution in the Antilles and Latin America. The total named fauna is thus about 72% naturally occurring, and 28% the result of human-aided dispersal.

Review of the Natural History of the Handsome Fungus Beetles (Coleoptera: Cucujoidea: Endomychidae)
(2009)
The literature pertaining to natural history of Endomychidae (Coleoptera: Cucujoidea) is reviewed. One hundred fungal host records are provided for 32 endomychid species. Twenty-three records of endomychid yeast endosymbionts are compiled. Summaries are also presented for feeding preferences, interactions with natural enemies, non-lethal symbiotic relationships, and pest activity within the family. Unusual endomychid behaviors and habitats are reviewed, with particular attention to gregariousness and defensive strategies within Endomychidae.

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.
