Abstract Leptotarsus reyi sp. nov., first representative of the family Tipulidae from the Lower Cretaceous of Lebanon, is characterised, described and illustrated from the Early Barremian dysodile of Jdeidet Bkassine, South Lebanon.

| 9:27a | [Entomology • 2023] Olceclostera quilombola, O xeta, etc. • More than Olceclostera bifenestrata: New Species and Morphology of immature stages of Olceclostera Butler, 1879 (Lepidoptera: Bombycoidea: Apatelodidae)
Abstract Apatelodidae is a family of Neotropical bombycoids that still needs to be studied in several aspects, as many groups of species have not yet undergone a careful systematic revision. On the other hand, recent studies showed that some species known to be widely distributed in fact form species complexes. Until now, Olceclostera bifenestrata Schaus, 1912, described from Costa Rica, supposedly has a wide distribution, reaching the south of Brazil. We reviewed specimens from South America identified as O. bifenestrata. Using morphological data and DNA barcodes, we discovered that South American specimens belong to four new species: Olceclostera jairana sp. nov., Olceclostera quilombola sp. nov., Olceclostera xeta sp. nov. and Olceclostera wayana sp. nov. The four species can be distinguished mainly by characters of genitalia, mostly in aedeagus structures. However, wing characters (number of hyaline spots) and abdomen characters (number of patches of larger scales) may be useful for classifying species groups in Olceclostera. Additionally, we illustrate and describe for the first time all the life stages of an Olceclostera species, including its chaetotaxy and life history, and provide the first SEM images of the egg of an Apatelodidae species. We present a discussion about the morphological characters of adults and immatures and their relevance to the systematics of Apatelodidae.

| 2:21p | [Fungi • 2017] Arthrophaga myriapodina (Entomophthoraceae) • The first entomophthoralean killing Millipedes, causes climbing before host death
Highlights: • Arthrophaga myriapodina is a new genus and species of fungus pathogenic to millipedes in the eastern USA. • Infected millipedes climb before dying, then fungal spores are forcibly shot from cadavers. • Arthrophaga myriapodina is the first known pathogen of millipedes in the order Entomophthorales. Abstract A new species and genus of entomophthoralean fungus, Arthrophaga myriapodina kills polydesmid millipedes. This species was first seen over a century ago but never described. It is the first millipede pathogen known from the order Entomophthorales, species of which are best known as pathogens of a wide diversity of insects. The fungus induces pre-death climbing behavior in its hosts, enabling the fungus to broadcast its forcibly-discharged conidia from a high vantage, which presumably increases the fitness of the fungus. Study of herbarium specimens and photographic discoveries on the internet suggest the fungus occurs widely in eastern North America.

They belong to sister tribes in Myriapoda: Polydesmidae: Apheloria virginiensis corrugata in tribe Apheloriini; Nannaria sp. in tribe Nannariini; and Boraria infesta in tribe Rhysodesmini. Kathie T.

| 2:21p | [Invertebrate • 2023] Xyloplax princealberti (Echinodermata: Asteroidea) • A New Species that is not always associated with Wood Falls
Abstract Xyloplax is a genus of three species of sea stars previously found only on sunken wood in the deep ocean. Their circular and petaloid bodies, which lend them their common name “sea daisy”, and their presumed exclusive diet of wood make them an unusual and rare element of deep-sea ecosystems. We describe here the fourth species of Xyloplax from the eastern Pacific Ocean, Xyloplax princealberti n. sp., which ranges from offshore Canada to the Gulf of California (Mexico) and Costa Rica. Though sampled geographically close to another described species of Xyloplax from the northeastern Pacific, X. janetae, this new species is unique morphologically and according to available DNA data. The short abactinal spines are the most obvious feature that distinguishes X. princealberti n. sp. from other Xyloplax. The minimum distance for mitochondrial cytochrome c oxidase subunit I from Xyloplax princealberti n. sp. to the only other available Xyloplax, X. janetae, was 13.5%. We also describe Ridgeia vestimentiferan tubeworm bushes from active hydrothermal vents as a new Xyloplax habitat, the first record of a non-wood substrate, and a new reproductive strategy, simultaneous hermaphroditism, for this genus. We generated the first mitochondrial genome for a member of Xyloplax and analyzed it with other available asteroid data using nucleotide-coding or amino acid (for protein-coding genes) plus nucleotide coding (for rRNA genes). The nucleotide-coding results place Xylopax as part of the clade Velatida, consistent with a previous phylogenomic analysis that included Xyloplax princealberti n. sp. (as Xyloplax sp.), though the placement of Velatida within Asteroidea differed. The amino acid plus nucleotide coding recovered Velatida to be a grade with X. princealberti n. sp. as sister group to all other Asteroidea. Keywords: deep sea; asteroid; hydrothermal vent
VELATIDA XYLOPLACIDAE Baker, Rowe & Clark, 1986 Xyloplax Baker, Rowe & Clark, 1986 Xyloplax princealberti n. sp. Diagnosis: Xyloplax with rounded abactinal spine bases, spines uniformly short. Two to three adambulacral spines per plate; more than 100 total spines around margin. Tube feet rounded, bulbous, up to ten per segment. Terminal plates badge-shaped. Mouth, gut, and anus absent. “Viviparous”, simultaneous hermaphrodite. Etymology: This species honors His Serene Highness Prince Albert II of Monaco for his efforts to protect the marine environment through the Prince Albert II of Monaco Foundation. Cheyenne Y.
