Size equivalence, seasonal synchronicity, geospatial sympatry, habitat specificity, and host-searching behavior implicate the spider wasp Chalcochares hirsutifemur (Banks) (Hymenoptera: Pompilidae: Pompilinae) as an obligate parasitoid on species of the wafer-lid spider genus Aptostichus Simon (Araneae: Mygalomorphae: Euctenizidae) on coastal sandy back dunes in San Luis Obispo and Santa Barbara counties, CA. This is substantiated by 2010–2022 macrophotographs, videos, and field observations. Such host evidence supports recent unpublished phylogenomic studies that place Chalcochares as a sister genus of the spider wasp tribe Aporini, in which all species are known obligate parasitoids on trapdoor spiders and related Mygalomorphae. Chalcochares hirsutifemur and C. engleharti (Banks) are separated based on morphological, geographic, and probable host spider differences. Resource partitioning on the coastal sand dunes between C. hirsutifemur and three species of smaller Aporus Spinola is proposed.

Close-up photographs of nest entry, nest closure and prey transport taken on sandy coastal back dunes in Santa Barbara County, CA by Alice J. Abela substantiate and enhance written descriptions of these nesting behavior components in Miscophus californicus (Ashmead) [=M. laticeps (Ashmead)] (Hymenoptera: Crabronidae). Dictynidae (Dictyna Sundevall or Emblyna Chamberlin) is introduced as a new host family and host spider leg amputation is revealed for the first time for this small miscophine wasp.

Macrophotographs in series taken by Alice Abela on sandy coastal dunes in Santa Barbara and San Luis Obispo Counties, CA in 2010–2021 supplement and enhance F. X. Williams (1928) study of the ecology and nesting behavior of the trapdoor spider-hunting spider wasp Aporus (Plectraporus) hirsutus (Banks) (Hymenoptera: Pompilidae: Aporini). Abela’s macrophotographs and observations provide new details of adult wasp feeding, functional morphology, hunting, digging and prey transport, and host spider trapdoor, entrance, burrow structure, host capture and escape activity. Newly reported host records from this study and online photographs expand A. hirsutus host selection in the large wafer-lid trapdoor spider genus Aptostichus Simon (Araneae: Mygalomorphae: Euctenizidae). The A. hirsutus California geographic distribution map by Wasbauer and Kimsey (1985) is updated, thereby providing a broader definition of intraspecific variation in this species.

Nesting behavior of the spider wasp Calopompilus pyrrhomelas (Walker) (Hymenoptera: Pompilidae)
(2023)
The nesting behavior of the spider wasp Calopompilus pyrrhomelas (Hymenoptera: Pompilidae: Pepsini) is described for the first time based on independent observations and photographic series from Oakland, Alameda County, CA; Denio, Humboldt County, NV; and Tamalpais-Homestead Valley, Marin County, CA, respectively. The three wasps captured, immobilized, and provisioned the spider’s own burrows with Calisoga longitarsis (Simon) (Nemesiidae) and Antrodiaetus montanus (Chamberlin and Ivie) (Antrodiaetidae).

Hurd (1952) separated Pepsis cerberus Lucas from P. elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini) based on external morphology and biogeography. Vardy (2005) synonymized the familiar and historically well-documented P. cerberus and P. elegans, combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P. menechma Lepeletier. In doing so, Vardy (2005) breached the principle of nomenclatural stability. He ignored the prevailing usage and clearly violated articles 23.2, 23.3 and 23.9.1.2 of the ICZN (1999). Morphological differences, ecological divergence, and narrow sympatric geographic distribution of P. cerberus and P. elegans contradict Vardy (2005) and justify full species status (Kurczewski 2023a). Furthermore, we propose the removal of the two species from the P. menechma list of synonyms and recommend full species reinstatement as Pepsis cerberus, restored status and Pepsis elegans, restored status. Pepsis menechma becomes a senior synonym of P. elegans. Morphometric re-examination and statistical analysis of P. cerberus and P. elegans structural features strongly support their reinstatement. Quantitative measurement of 10 parasitoid-related morphological characteristics of the females revealed the two species differ significantly in frons width/head width, head length/head width, vertex length/head width, vertex length/head length, flagellomere 1 length/flagellomere 1 width, forewing length/mesosoma width, and hind tibial inner spur length/hind basitarsus length. Pepsis cerberus and P. elegans females are structurally and statistically similar in gena-postgena corner radius, fore femur width/mesosoma width, and number of hind tibial serrations.

This paper is the sequel to a 20 year-long (2002–2021) study of geographic variation in host selection in the common American spider wasps (Hymenoptera: Pompilidae) Entypus unifasciatus (Say) (Pepsini) and Tachypompilus ferrugineus (Say) (Pompilini) (rusty spider wasp). Geography and host spider family are strongly linked in both species when 3387 host spider locality records from the years 1918–2021 are mapped. Entypus unifasciatus lycosid host records are plentiful from 43–44° N in the United States and southern Ontario to northern Mexico. Tachypompilus ferrugineus lycosid host records are abundant from southern Ontario and New England southward to Mexico east of the Rocky Mountains. The vast majority (~80%) of E. unifasciatus and T. ferrugineus pisaurid host records are from the southeastern United States. Trechaleid host records for E. unifasciatus and T. ferrugineus are predominant in southern Mexico and Central America,
while ctenid host records for these spider wasps are prevalent in Central America and, especially, South America. All E. unifasciatus sparassid host records are from extreme southwestern United States and northern Mexico, whereas T. ferrugineus sparassid host records are scattered from Texas, Florida and Hispaniola/Puerto Rico southward to Panama and Brazil. Based on this study Lycosidae is the predominant host spider family in the Americas for E. unifasciatus (83.1%) and T. ferrugineus (64.0%) followed by Pisauridae (4.9%, 24.8%), Trechaleidae (4.2%, 6.0%), Ctenidae (4.3%, 2.7%), and Sparassidae (3.1%, 1.6%). Lycosidae and Pisauridae are overrepresented in this study as most host records (88.1%) are from the United States and Ontario, Canada where such species are abundant. Trechaleidae and Ctenidae are grossly underrepresented as host records from Mexico, Central America and South America are scarce (11.9%). Zoropsidae/Miturgidae and Zoropsidae / Agelenidae / Selenopidae are atypical host spider families for E. unifasciatus (0.2%, 0.2%) and T. ferrugineus (0.7%, 0.2%, <0.1%), respectively. Rabidosa rabida (Walckenaer) (Lycosidae) (rabid wolf spider) is the predominant host spider species for both E. unifasciatus (47.7%) and T. ferrugineus (48.0%) based mainly on United States host records.

Geography and host spider family are strongly linked in the spider wasps (Hymenoptera: Pompilidae) Entypus unifasciatus (Say) and Tachypompilus ferrugineus (Say) (rusty spider wasp) when 2031 host spider locality records from the years 1918–2020 are mapped. Entypus unifasciatus lycosid host records are plentiful from 43–44° N in the U.S. to northern Mexico. Tachypompilus ferrugineus lycosid host records are numerous from southern Ontario and New England to Mexico east of the Rocky Mountains. Most E. unifasciatus and T. ferrugineus pisaurid host records are from the SE U.S. Trechaleid host records for E. unifasciatus and T. ferrugineus are predominant in southern Mexico and Central America, while ctenid host records for these species are prevalent in northern South America. All E. unifasciatus sparassid host records are from extreme SW U.S. and Mexico, whereas T. ferrugineus sparassid host records are scattered from Texas, Florida and Puerto Rico to Panama. Lycosidae are the predominant host spider family in the Americas for E. unifasciatus (80.3%) and T. ferrugineus (67.4%) followed by Pisauridae (5.4%, 21.7%), Trechaleidae (4.8%, 6.8%), Ctenidae (4.6%, 1.8%), and Sparassidae (4.3%, 1.5%). Lycosidae and Pisauridae are overrepresented in this study as the vast majority of host records (87.8%) are from the U.S. and Ontario, Canada where such species are abundant. Trechaleidae and Ctenidae are grossly underrepresented as host records from Mexico, Central America and South America are scarce (12.2%). Zoropsidae/Miturgidae and Zoropsidae/Agelenidae are atypical host families for E. unifasciatus (0.3%, 0.3%) and T. ferrugineus (0.4%, 0.4%), respectively. Rabidosa rabida (Walckenaer) (Lycosidae) (rabid wolf spider) is the predominant host spider species for both E. unifasciatus (56.8%) and T. ferrugineus (58.3%).

The use of common names for species and subspecies of North American spider wasps (Hymenoptera: Pompilidae) presents a variety of questions for pompilid specialists as most pompilid taxa are difficult to identify, even under the microscope. Some common names currently being used for spider wasp species are acceptable while others are misleading, unfit and unacceptable. Opinions on the relative value of common names for spider wasps from current Pompilidae researchers are given in the Introduction. Eleven inappropriate common names for North American Pompilidae species and subspecies are identified and discussedin the Results.

Host records and nesting behavior of the Nearctic trapdoor spider-hunting spider wasps (Hymenoptera: Pompilidae) Calopompilus Ashmead and Priocnemissus Haupt (Pepsinae: Pepsini) and Aporus Spinola and Psorthaspis Banks (Pompilinae: Aporini) are reviewed, investigated, compared, and discussed. First time incidental trapdoor spider host records for Priocnemis (Priocnemissus) minorata Banks (Pepsinae: Pepsini), Anoplius (Lophopompilus) carolina (Banks) (Pompilinae: Pompilini), and Notocyphus dorsalis dorsalis Cresson (Notocyphinae: Notocyphini) are included, although they are not typical trapdoor spiderhunting spider wasp species. The Palearctic Aporus (Aporus) unicolor Spinola, A. (Aporus) bicolor Spinola and A. (Aporus) planiceps (Latreille) are referenced for comparison with Nearctic Aporus sensu stricto. Early 20th century papers on species of Aporus and Psorthaspis are revived. New information on nesting behavior of Nearctic trapdoor spider-hunting spider wasps is described and first host trapdoor spider records for Psorthaspis formosa (Smith), P. legata (Cresson) and P. mariae (Cresson) are documented. Potential Pompilidae species in the genera Calopompilus and Aporus are suggested for host trapdoor spider remains found in burrows with spider wasp eggs, larvae and cocoons (pupae) based on geographic distribution, habitat, spider species, trapdoor and burrow structure, wasp cocoon size, and wasp congeneric host records.

Four online photographs from Oaxaca, Mexico taken by N. R. Jenzen-Jones and posted on inaturalist.org reveal Selenops sp., probably S. mexicanus Keyserling (Arachnida: Araneae: Selenopidae), as a new host spider species, genus and family for the common and widespread American spider wasp Tachypompilus ferrugineus (Say) (rusty spider wasp). The wasp transported the immobilized spider up an exterior stucco wall of a house, dorsal side upward, walking backwards for 3m to her nest in a gap between the wooden planking and stucco wall beneath the roof, while grasping the femur of its right pedipalp with her mandibles.

First host record, prey transport, and burrow excavation are described for Hesperopompilus sp., an undescribed, rare spider wasp (Hymenoptera: Pompilidae) from Texas. Taxonomic, ecological, and behavioral examination of the genus subsequently led to an investigation of the previously related Perissopompilus Evans and Xerochares Evans. Taxonomic, host preference, nesting behavior, and phylogenomic relationships of the three taxa are discussed along with those of Xenopompilus Evans. The molecular connection of Perissopompilus and Allochares Banks is supported by their common use of host species of Filistatidae.

We present new and atypical host records for 78 species, subspecies, species-groups, and variants of spider wasps (Hymenoptera: Pompilidae) from North America and South America. The records are listed in modified taxonomic order following the Catalog of Hymenoptera in America North of Mexico, Volume 2, Apocrita (Aculeata) (Krombein 1979). These records are an extension of previous host records reported by Kurczewski (2010), Kurczewski and Edwards (2012), and Kurczewski et al. (2017, 2020, 2022b). New genus and species host records are given for the genera and subgenera Calopompilus Ashmead, Chirodamus Haliday, Pepsis Fabricius, Hemipepsis Dahlbom, Priocnessus Banks, Entypus Dahlbom, Pompilocalus Roig-Alsina, Priocnemis Schiødte, Auplopus Spinola, Ageniella Banks, ?Aridestus Banks, Agenioideus (Agenioideus) Ashmead, Sericopompilus Howard, Episyron Schiødte, Poecilopompilus Ashmead, Tachypompilus Ashmead, Lophopompilus Radoszkowski, Notiochares Banks, Arachnophroctonus Howard, Anoplius Dufour, Xerochares Evans, Ammosphex Wilcke, Arachnospila Kincaid, and Priochilus Banks.

We present 112 new and unusual host records for 63 species and subspecies of Pompilidae (Hymenoptera) from the Western Hemisphere in modified taxonomic order according to the Synoptic Catalog of Hymenoptera (Krombein 1979). These records supplement those reported in a recent study by Kurczewski et al. (2020b). New and atypical genus and species host records are given for the genera Calopompilus Ashmead, Herbstellus Wahis, Pepsis Fabricius, Priocnessus Banks, Entypus Dahlbom, Pompilocalus RoigAlsina, Sphictostethus Kohl, Priocnemis Schiødte, Caliadurgus Fabricius, Epipompilus Kohl, Auplopus Spinola, Ageniella Banks, Eragenia Banks, Agenioideus Ashmead, Sericopompilus Howard, Poecilopompilus Ashmead, Tachypompilus Ashmead, and Priochilus (Fabricius). New host spider families are introduced for species of Calopompilus (Nemesiidae), Pepsis (Idiopidae, Pycnothelidae), Priocnessus (Euagridae), Entypus (Agelenidae), Ageniella (Theridiidae, Zoropsidae), Agenioideus (Theridiidae), Poecilopompilus (Salticidae), Tachypompilus (Anyphaenidae, Xenoctenidae, Pycnothelidae), Xerochares (Sparassidae), and Priochilus (Agelenidae). Curicaberis ?culiacans Rheims (Sparassidae), as prey of Xerochares expulsus (Schulz), is the first host record for this rare monotypic genus. Four new host spider families are reported from the Western Hemisphere for the first time: Idiopidae for Pepsis terminata, Pycnothelidae for Pepsis completa Smith and Tachypompilus mendozae (Dalla Torre), Euagridae for Priocnessus hurdi Dreisbach, and Xenoctenidae for T. mendozae. Pycnothelidae represents the first host record of a mygalomorph spider [Acanthogonatus ?incursus (Chamberlin)] for the worldwide genus Tachypompilus, based on more than 2500 host records. Amputation of the host spider’s legs and Ageniellini method of prey transport is highly unique in Poecilopompilus mixtus.

Four new species of the genus Polyphylla Harris (Coleoptera: Scarabaeidae: Melolonthinae) from the southwestern United States and Baja California, Mexico, are described and illustrated: Polyphylla anivallis, P. koso, P. morroensis, and P. socorriana. Two nomenclatural changes are proposed: Polyphylla ratcliffei Young is placed into synonymy with P. avittata Hardy and Andrews, new synonymy; P. uteana Tanner is removed from synonymy and reinstated as a valid species, reinstated status. The females of P. monahansensis Hardy and Andrews and P. stellata Young are described and illustrated. New distributional records and ecological associations are amended for P. avittata Hardy and Andrews, P. cavifrons LeConte, P. concurrens Casey, P. crinita LeConte, P. diffracta Casey, P. mescalerensis Young, P. petitii (Guérin-Méneville), and P. rugosipennis Casey. A checklist of the “Western Clade” species of Polyphylla, north of Mexico, is included.

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.

Morphological and cytochrome oxidase 1 (Cox1) data show that Aphis floridanae Tissot (Hemiptera: Aphididae) is not synonymous with A. nasturtii Kaltenbach. Instead, A. floridanae matches the morphological characters of A. impatientis Thomas. Additionally, the range of cytochrome oxidase 1 (Cox1) pair-wise distance of the multiple collections of A. impatientis on Cornus spp., Impatiens spp. and Erechtites hieraciifolius (L.) Raf. ex DC. is 0–0.39%. Therefore, we conclude that A. floridanae Tissot, 1933 is a junior synonym of A. impatientis Thomas, 1878, new synonymy. In addition, A. impatientis is re-described, including first descriptions of the ovipara and alate male of that species.

The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is a major pest of soybean, Glycine max (L.) Merr., both in Asia where it is native, and in the USA where it is adventive. The rapid spread and establishment of the soybean aphid in the USA since its discovery in 2000 was successful because of extensive soybean production in the Midwest and the wide distribution of common buckthorn, Rhamnus cathartica (L.), its preferred primary winter host. The survivorship of four soybean aphid biotypes on common and glossy buckthorn, Frangula alnus Mill., were compared. Our study showed that nymph oviparae of soybean aphid biotypes 1, 2, 3 and 4 reached adulthood and produced eggs on glossy buckthorn. When comparing morphs between the hosts, greater numbers were recorded on common than glossy buckthorn, with one exception where the number of eggs per bud for soybean aphid biotype 2 was not different between the hosts. We found for the first-time soybean aphid biotypes 2 and 3 apterous males produced on common and glossy buckthorn. Morphological descriptions of live and mounted alate and apterous males are presented.

Lipaphis alliariae Müller (Hemiptera: Aphididae) was identified from specimens collected in Lake County, Ohio, on the invasive garlic mustard, Alliaria petiolata (Bieb.) Cavara & Grande (Brassicaceae). The identification was performed on apterous viviparae using morphological and molecular data. Body color and shape of the cauda discriminated L. alliariae and L. pseudobrassicae Davis. Measurements of morphological characters of both species were similar, but they have distinct characters distinguishing them fromL. erysimi Kaltenbach. Neighbor-joining analysis of cytochrome oxidase 1 (Cox1) barcoding indicated a close relationship of the aphids that feed on Brassicaceae, and the range of pair-wise distances for Cox1 barcoding of these species was 0.3–0.9%.

Aphis elena Lagos-Kutz and Voegtlin, sp. nov. (Hemiptera: Aphididae), is described from specimens collected in Illinois, USA, on the North American native plant, Pycnanthemum virginianum (L.) T. Dur. & B.D. Jacks. ex B.L. Rob. & Fernald (Family: Lamiaceae). Both apterous and alate viviparae are described and illustrated, and a dichotomous key is provided to apterous and alate viviparae of the six species of Aphis that have been recorded on plants in the family Lamiaceae in North America. Neighbor-joining analysis of cytochrome oxidase 1 (Cox1) indicated a close relationship of the new species with Aphis monardae Oestlund, which also feeds on a member of Lamiaceae. The range of pair-wise distances for DNA barcoding of these species is 0.17–0.33%. The newly described Aphis elena is morphologically more similar to Aphis gossypii Glover than it is to Aphis monardae.
