| 1:25p | [Entomology • 2022] Druon laceyi • Discovery through iNaturalist: New Species and New Records of Oak Gall Wasps (Hymenoptera: Cynipidae: Cynipini) from Texas, USA
Abstract A new species of the genus Druon Kinsey, 1937, Druon laceyi Zhang, Sasan & O’Kennon sp. nov. is described on host plant Quercus laceyi Small from central Texas. We also re-establish Andricus lustrans Beutenmüller, 1913 comb.rev., and transfer Striatoandricus aciculatus (Beutenmüller, 1909) comb. nov. from Andricus. Finally, we report a new state and host record for Druon gregori Melika, Nicholls & Stone, 2022. All observations were first shared on the social platform iNaturalist, highlighting the potential of cybertaxonomy in uncovering overlooked biodiversity.

| 1:25p | [Crustacea • 2022] Bathynomus yucatanensis • A New Species of Bathynomus Milne-Edwards, 1879 (Isopoda: Cirolanidae) from the southern Gulf of Mexico with A Redescription of Bathynomus jamesi from off Pratas Island, Taiwan
ABSTRACT Bathynomus jamesi Kou, Chen and Li, 2017 from Zhengbin fishing port in Keelung, Taiwan, was identified by the shape of the distolateral corner of the uropodal endopod, the shape of the clypeus, and the nucleotide sequences of the COI (cytochrome c oxidase subunit 1) and 16S rRNA genes. Only two species of Bathynomus have previously been recorded from Taiwan, B. doederleini Ortmann, 1894 and B. decemspinosus Shih, 1972. Bathynomus kensleyi, previously known from the South China Sea as well as the south-east Swain Reefs, Coral Sea, was primarily differentiated by the elongate and upturned pleotelson spines, but that character is now shown to also occur in mature Bathynomus jamesi. Two specimens from the Gulf of Mexico (obtained from the Enoshima Aquarium in Japan) were compared to species of Bathynomus from the western North Atlantic. Sequence data showed that one of two samples was not B. giganteus Milne-Edwards, 1879, as had been assumed, and it did not match any other species of Bathynomus. That specimen was collected off the Yucatán Peninsula and is morphologically distinct from both B. giganteus (in the relative length of the antennal flagellum and the length:width ratio of the pleotelson) and B. maxeyorum Shipley, Brooks, and Bruce in Shipley et al., 2016 (the number of pleotelson spines is seven and the distolateral corner is produced on the uropodal exopod). Therefore, it is here described as Bathynomus yucatanensis sp. nov. Bathynomus is currently a very minor fisheries resource in Taiwan and Japan, but this find demonstrates the continuing importance of the fishing industry to marine biological exploration. KEYWORDS: Cirolanidae, South China Sea, Taiwan, Bathynomus kensleyi, Bathynomus yucatanensis sp. nov Order Isopoda Latreille, 1817 Family Cirolanidae Dana, 1852 Genus Bathynomus Milne-Edwards (1879)
Bathynomus yucatanensis sp. nov. Diagnosis: Clypeus with straight lateral margins. Antennal flagellum extending to within pereonite 3. The distal part of the coxa of pereopod 7 is broad. Uropodal exopod not extending beyond pleotelson: endopod with distolateral corners slightly produced. Length:width ratio of pleotelson approximately 0.8:1; number of pleotelsonic spines 11 or 13, short, or straight. Habitat: Captured with B. giganteus, presumably similar to B. giganteus. Distribution: Off the Yucatán Peninsula of Mexico, and in the Gulf of Mexico; approximate depth range 600–800 metres. Etymology: The epithet is an adjective derived from the name of the nearest land mass to its common locality, the Yucatán Peninsula. The Japanese name: Enosuigusokumushi.

| 1:30p | [Paleontology • 2022] Reappraisal of the largest ctenochasmatid Moganopterus zhuiana Lü et al. 2012 (Pterosauria: Ctenochasmatidae)
Moganopterus zhuiana Lü et al., 2012 was erected as a member of the Boreopteridae, which was questioned by different researchers shortly after the publication. Although the new assignment to the Ctenochasmatidae is widely accepted by pterosaur researchers, some characteristics still require a detailed description. Here, the holotype of this taxon is restudied, and some ambiguous characteristics are re-identified. The diagnosis of this taxon has been revised as the following: a large ctenochasmatid pterosaur, which can be distinguished from other members of this clade by a single autapomorphy: an elongated rod-like parietal crest that extends posterodorsally, forming an angle of about 15° with the ventral margin of the skull. This taxon can be further distinguished from other ctenochasmatids on the basis of the following combination of characteristics: straight occlusal surfaces of the upper and low jaws; presence of a low premaxillary crest confined anterior to the nasoantorbital fenestra; rostrum about two thirds of the skull length; nasoantorbital fenestra occupying slightly more than 20% of the skull length; about 100 slender teeth; and a mid-cervical length/width ratio of about 7. The wingspan of M. zhuiana has been re-estimated according to a simple regression equation for wingspan versus skull length in ctenochasmatids. It confirms that M. zhuiana, although smaller than previous thought, is still the largest known ctenochasmatid. When comparing the sizes of ctenochasmatids in the Jurassic and Cretaceous, ctenochasmatids showed a rough tendency to increase their sizes.
