Considerations of the alimentary canal, mesodermal reproductive organs, and ventral nervous system and brain are provided. The treatise is based on studies of 301 species, representing 99 genera, 11 subfamilies, and two cleroid families. A comparative morphology summary is provided. Morphological variations of the stomodaeum, ventriculus, malpighian tubules, confi guration of the spermathecal capsule, shape of the bursa copulatrix, male accessory glands, and testes provide taxonomically useful characteristics. Provided are 252 illustrations. A new name, Katachaetosoma, nom. nov., is proposed to replace the preoccupied name Chaetosoma Dejean (Insecta: Coleoptera: Cerambycidae).

Sundapyrochroa, a new genus of pyrochroine Pyrochroidae, is described from three Sunda Shelf species most recently assigned to Pseudopyrochroa Pic: Sundapyrochroa atricolor (Pic), comb. nov., recorded from Peninsular Malaysia, Sundapyrochroa nigripennis (Pic), comb. nov., recorded from Peninsular Malaysia, and Sundapyrochroa sumatrensis (Pic), comb. nov., recorded from Borneo (Malaysia: Sabah) and Sumatra (Indonesia). Schizotus rotundicollis Pic, syn. nov., is proposed as a junior synonym of S. sumatrensis. No evidence could be found to support subspecifi c categories for S. nigripennis, thus, Pseudopyrochroa nigripennis notaticeps Pic, syn. nov., is proposed as a junior synonym of S. nigripennis. Gross anatomy of the cranium (female, male), antennae (female, male), and genitalia (male) are both diagnostic and enigmatic, suggesting no clear relationships with other pyrochroine genera.

Tynommatidae, n. stat., elevated from Tynommatinae, is established as a schizopetalidean family encompassing the western North American callipodidans previously assigned to the Mediterranean Schizopetalidae. It is considered a valid taxon despite somewhat anatomically dissimilar subfamilies, and Colactidinae, Texophoninae, Diactidinae, and Aspidiophoninae constitute tribal elevations and additional new statuses. With a subbasal telopodal prefemoral process, Diactis hedini, n. sp., requires rediagnoses of all three diactidine genera, Diactis Loomis, 1937, and Florea and Caliactis, both by Shelley, 1996, and suggests that telopodal branches ‘B’ in congeners and Florea represent distal relocations of the process along the stem. Similarities in the sizes and shapes of the pleurotergal carinae suggest a sister-group relationship with the other, and partly sympatric, New World family, Abacionidae, which is supported by gonopodal similarities between Colactidinae and Abacion Rafi nesque, 1820. The Western Interior Seaway of the Cretaceous Period, Mesozoic Era, ~141–66 million years ago, appears to have fueled divergence by isolating “proto-abacionid stock” in “Appalachia,” the Eastern North American land mass, which has subsequently spread well into previously inundated areas. The allopatric position of Texophoninae, on the Gulf Coast of south Texas around 1,136 km (710 mi) east of the most proximate familial records, is attributed to this waterway, which eradicated faunal linkages with “proto-Tynommatidae” in “Laramidia,” the Western North American land mass. Texophoninae probably survived the Cretaceous on insular refugia; however, it is rarely encountered anymore and seems destined for imminent extinction. Representatives of the east-Asian families, Caspiopetalidae, Paracortinidae, and Sinocallipodidae, also possess demarcated pleurotergal crests and, implausible though it seems, may share ancestry with the North American taxa vis-à-vis the “Asiamerica” and or “Boreotropic” concepts.

A recent investigation was conducted to assess the threat of insect venom hypersensitivity to deployed U.S. service members operating in the region. In parallel with this study, a checklist of medically important Hymenoptera was assembled from limited fi eld collections as well as a comprehensive review of the literature and information provided by electronic databases. We compiled names of 14 families comprising 396 species of Hymenoptera capable of stinging humans. This is the first such checklist for Afghanistan, and should aid future taxonomic work and provide reference information for public health-related entomology in this region.

Scolopendra morsitans L., 1758, is documented from Honolulu, Oahu, Hawaiian Islands, the fi rst record of this anthropochoric chilopod from both the archipelago and state. Hawaii thus becomes the second American state to harbor the species, the other being Florida, where an individual has been taken in Jacksonville, Duval County. Meristic and morphological data are presented for three Hawaiian specimens. At least two other species of Scolopendra, both introduced, occur on these islands: S. polymorpha Wood, 1861, known only from one specimen from Oahu, and one or more representatives of the “S. subspinipes Leach, 1815, complex,” which is widespread and even inhabits Midway Atoll.

A new species of coffee stem and root borer from Colombia is described: Plagiohammus colombiensis, sp. nov. (Coleoptera: Cerambycidae: Lamiinae). The new species differs from other species of the genus Plagiohammus Dillon and Dillon by the yellow pattern of spots on the elytra, the morphology of the antenna and pronotum as well as characters of the male genitalia. A key to species of Plagiohammus is provided. This study examines the current situation of the new species of coffee stem and root borer in Colombia. Information on its biology and damage to the coffee plantations is presented.

Two new species of Deltosoma Thomson, 1864 are described from French Guiana: D. humeralis sp. nov. and D. fernandezi sp. nov. Deltosoma lacordairei Thomson, 1864 is redescribed based on examination of the holotype. A study of the aedeagi of these three species was conducted. Dorsal habitus photographs of both sexes, ventral photographs of males, and aedeagi photographs are provided.

Chromosomes of four rare and localized Caribbean Prioninae (Coleoptera: Cerambycidae) species were analysed. All have 26, XY karyotypes. Those of Solenoptera canaliculata (Solenopterini) from Guadeloupe nearby islands Les Saintes and Marie-Galante and S. quadrilineata from Martinique look similar. They have a single pair of sub-metacentric autosomes. The karyotype of S. touroulti from St. Lucia has three sub-metacentric pairs. It appears closer to that of Hovorodon maxillosum (Mallodontini) from Marie-Galante which has ten sub-metacentric pairs. The CO1 gene sequence, taking two European species Aegosoma scabricorne (Prioninae: Aegosomatini) and Ergates faber (Prioninae: Ergatini) as external groups was analysed in S. canaliculata and S. quadrilineata. In spite of their karyotype similarity, their CO1 genes differ by a strong accumulation of mutations. Thus, either chromosomal or genetic data confirm the species status of the three closely related Solenoptera species. Ten different CO1 haplotypes are found among the 21 specimens of S. canaliculata studied from les Saintes and Marie-Galante. Both different haplotypes were found in each island and identical haplotypes were found in different islands. Hence, the gene flow was not interrupted. Biogeographical parameters favor the hypothesis that repeated passages between islands were made possible by floating trunks, principally from Les Saintes to Marie-Galante.

We present new southeastern United States distributional records for Stictoleptura canadensis (Olivier, 1795), Leptura subhamata Randall, 1838 (Coleoptera: Cerambycidae: Lepturinae), and Heterosternuta cocheconis (Fall, 1917) (Coleoptera: Dytiscidae: Hydroporinae) which extend the southernmost limits of the known distributions for these species. We present new state records for these species.
