| 2:30a | [Entomology • 2023] Loboscelidia barbata, L. convexa, L. glabra, L. piriformis, etc. • Taxonomic Revision of the Genus Loboscelidia Westwood, 1874 (Hymenoptera: Chrysididae: Loboscelidiinae) from Vietnam
ABSTRACT The taxonomy of Loboscelidiinae in Vietnam is revised, with 16 new species being described: Loboscelidia bachmaensis sp. nov., L. barbata sp. nov., L. cilia sp. nov., L. convexa sp. nov., L. cucphuongensis sp. nov., L. cuneata sp. nov., L. do sp. nov., L. flavipes sp. nov., L. glabra sp. nov., L. komedai sp. nov., L. mediata sp. nov., L. parallela sp. nov., L. piriformis sp. nov., L. squamosa sp. nov., L. vang sp. nov. and L. vietnamensis sp. nov. In total, 24 species of Loboscelidia are recognized in the fauna of Vietnam. Keys to Indo-Chinese male and world female of Loboscelidia are provided. A brief observation of the foraging behavior of L. squamosa sp. nov. is also reported. Host-carriage and subsequent host egg burying are considered primary nesting behaviors of solitary wasps.

| 9:33a | [Paleontology • 2023] Garumbatitan morellensis • New Sauropod Dinosaur from the Lower Cretaceous of Morella (Spain) provides New insights on the Evolutionary History of Iberian Somphospondylan Titanosauriforms
Abstract A new somphospondylan titanosauriform from the Lower Cretaceous of Spain is described from the remains found at the Sant Antoni de la Vespa site (upper Barremian Arcillas de Morella Formation) located in Morella. Garumbatitan morellensis gen. et sp. nov. is diagnosed by 11 autapomorphies and eight local autapomorphies; and our phylogenetic analyses suggest that Garumbatitan morellensis might correspond to an early-branching somphospondylan. The presence of several somphospondylan traits in Garumbatitan morellensis supports the somphospondylan hypothesis. The phylogenetic distribution of some titanosauriform and somphospondylan novelties in the femur (markedly developed lateral bulge, high shaft eccentricity, linea intermuscularis cranialis, and trochanteric shelf) is discussed. The tarsus and pes of Garumbatitan morellensis are distinctive, being characterized by the loss of the calcaneum, relative slenderness of the metatarsals II, III, and IV when compared to the retracted metatarsals I and V, three pedal phalanges in digit IV, and reduced ungual III. The sauropod fauna of the Iberian Peninsula during the Hauterivian–Aptian shows a complex phylogenetic mosaic, including forms with Laurasian affinities, mainly titanosauriforms (Soriatitan, Garumbatitan, and possibly Tastavinsaurus and Europatitan), and Gondwanan affinities, the rebbachisaurid Demandasaurus. Faunal exchange during the Early Cretaceous between the Europe, North America, East Asia, and Africa is plausible.
