| 3:02a | [Mollusca • 2021] Molecular Phylogeny of the Limacoid Snail Family Dyakiidae in Southeast Asia, with the Description of A New Genus and Species
Abstract Members of the terrestrial snail family Dyakiidae from Southeast Asia show a distinct geographical distribution pattern and possess different degrees of complexity in their amatorial organ gland. This study is the first molecular phylogeny of ten of the 12 genera in this family, performed to provide insights into the origin of Dyakiidae and the evolution of their shells and amatorial organ gland structure. A new genus and new species, Pseudoquantula lenticularis Jirapatrasilp & Panha gen. & sp. nov., was uncovered based on its distinct morphological characters and molecular divergence. All other genera were retrieved as monophyletic except for Dyakia. Mainland Southeast Asia was inferred to be the ancestral range of the Dyakiidae, and the lineages then dispersed to and diversified in Borneo. Cladistic analysis showed that all 14 morphological characters used in this study were homoplastic. These results disagree with the previous amatorial organ transformation series, in which neither Pseudoplecta nor Quantula was ancestral to the other genera. The enigmatic genus Pseudoplecta, which lacks an amatorial organ gland, exhibited secondary loss. biogeography, cladistic analysis, homoplasy, molecular systematics, phylogenetics, plesiomorphy, Southeast Asia   Pseudoquantula lenticularis Jirapatrasilp & Panha  Parin Jirapatrasilp, Piyoros Tongkerd, Ekgachai Jeratthitikul, Thor-Seng Liew, Arthit Pholyotha, Chirasak Sutcharit and Somsak Panha. 2021.

| 6:30a | [Entomology • 2020] New and Unusual Host records for North American and South American Spider Wasps (Hymenoptera: Pompilidae)
Abstract New and unusual host records for 133 species and subspecies of Pompilidae predominantly from the southwestern United States, Mexico, Central America, and South America are presented in modified taxonomic order. First-time species host records are given for Calopompilus Ashmead, Pepsis Fabricius, Hemipepsis Dahlbom, Priocnessus Banks, Entypus Dahlbom, Pompilocalus Roig-Alsina, Sphictostethus Kohl, Auplopus Spinola, Ageniella Banks, Eragenia Banks, Aporus Spinola, Poecilopompilus Ashmead, Tachypompilus Ashmead, Anoplius Dufour, Priochilus (Fabricius) and Notocyphus Smith. New host spider families are introduced for Calopompilus, Pepsis, Hemipepsis, Priocnessus, Entypus, Cryptocheilus Panzer, Priocnemis Schiødte, Auplopus, Ageniella, Eragenia, Aporus, Tachypompilus, Anoplius, Priochilus and Notocyphus. Eight host spider families are reported from the Western Hemisphere for the first time: Halonoproctidae (Notocyphus dorsalis dorsalis Cresson); Dipluridae (Pepsis pretiosa Dahlbom, P. montezuma Smith, P. infuscate Spinola, P. atripennis Fabricius, P. martini Vardy, Priocnessus vancei Waichert and Pitts); Nemesiidae (Pepsis pallidolimbata Lucas, P. viridis Lepeletier, P. spp., Pompilocalus hirticeps (Guérin), Sphictostethus gravesii (Haliday), S. striatulus Roig-Alsina, Priocnemis oregona Banks); Barychelidae (Eragenia sp.); Paratropididae (Pepsis stella Montet); Trechaleidae (Hemipepsis toussainti (Banks), Entypus unifasciatus cressoni (Banks), Tachypompilus ferrugineus (Say), Tachypompilus unicolor cerinus Evans, Priochilus gloriosum (Cresson); Desidae (Ageniella accepta (Cresson), Sphictostethus isodontus Roig-Alsina) and Selenopidae (Priochilus scrupulum (Fox), Tachypompilus erubescens (Taschenberg) or xanthopterus (Rohwer)). The first known host records for the rare South American pompilid genera Chirodamus (Lycosidae: Lycosa sp.) and Herbstellus (Nemesiidae: Diplothelopsis cf bonariensis Mello-Leitão) are presented.
