| 1:18p | [Botany • 2024] Thrixspermum anceps, T. bromeliforme, T. crassilabre, T. pardale, T. tortum, ... • Eleven Species of Thrixspermum (Orchidaceae: Vandeae: Aeridinae) newly recorded from Thailand
Abstract Eleven species of Thrixspermum are newly recorded from Thailand. Four belong to sect. Thrixspermum: T. crassilabre (South-Western floristic region), T. lampongense (Eastern floristic region), T. latisaccatum (Peninsular), and T. tortum (Peninsular); and seven to sect. Dendrocolla: T. anceps (Peninsular), T. bromeliforme (of unknown provenance), T. duplocallosum (Peninsular), T. merapohense (Peninsular), T. pardale (Peninsular), T. patkaiense (Eastern), and T. pulchellum (Peninsular). Descriptions, photographs, and notes on distribution, ecology, phenology, vernacular names, and recognition are provided. Three names are lectotypified. Five species are considered to be uncommon in the wild: T. anceps, T. crassilabre, T. duplocallosum, T. patkaiense, T. tortum; and T. bromeliforme is known from cultivation and suspected to originate in Krabi Province, Peninsular Thailand.

| 1:52p | [Herpetology • 2024] Liopholis aputja • A New Species of Rock Skink (Scincidae: Liopholis) from the Central Ranges Bioregion of Arid Australia
Abstract A new species of rock skink Liopholis Fitzinger 1843 (Scincidae) is described from the Mann-Musgrave Ranges of north-western South Australia. Liopholis margaretae sensu lato (Storr 1968) is currently known to occur in two disjunct populations: the MacDonnell Ranges bioregion and nearby regions in the Northern Territory, and the Central Ranges bioregion in South Australia. Based on morphological examination of both museum and field specimens, as well as on newly generated molecular data, we show that specimens from these two ranges constitute distinct species. The new species, Liopholis aputja sp. nov. is endemic to a specific geological landform (Mann-Musgrave Ranges) within the Central Ranges bioregion, and is estimated to have diverged from the MacDonnell Ranges population during widespread aridification of the Miocene. Liopholis aputja sp. nov. is distinguished from congeners by a combination of its moderately large size (SVL up to 135 mm), relatively pointed snout, smooth dorsal scales, black and calloused subdigital lamellae and soles of feet, and possessing usually six supraciliary scales and usually four enlarged ear lobules. This new species adds to the list of endemic herpetofauna recognised in the Central Ranges bioregion.

Etymology. Aputja is a word from the Pitjantjatjara/yankunytjatjara language spoken by First Nations peoples where this lizard species is found in APY (Aṉangu Pitjantjatjara Yankunytjatjara) Lands of north-western South Australia. Aputja means ‘of the hills’, in reference to this species occurring in the hills and gorges of the Mann-Musgrave ranges, unlike other Liopholis spp. of the region which occur on sandplains. the specific epithet is constructed as a noun in apposition. In arriving at this name, we spoke to rangers, traditional owners and knowledge holders across the APy lands; in Pukatja, Fregon, Mimili/Amaroona, Indulkana, Amata and Pipalyatjara. responses to asking for the name of the new Liopholis species varied. however, particular clarity in narrowing the name down to Aputja was provided by the following traditional owners: Allan Wilson (Indulkana/Pukatja), Johnny Roberts (Fregon), Winmati Roberts (Fregon/umuwa), Manyiritjanu Lennon (Pukatja), and Hughie Cullinan (Mimili/Amaroona). The common name Central ranges rock Skink is chosen because L. aputja sp. nov. is endemic to the Central ranges bioregion (Thackway & Cresswell 1995). We chose the words ‘rock skink’ for clarity and consistency, given that most other saxicoline members of the Liopholis genus are commonly referred to as rock skinks (Australian Society of herpetologists 2023).

| 5:41p | [Botany • 2024] Croton antioquensis (Euphorbiaceae: Crotoneae) • A New Species of Croton section Geiseleria from the Canyon of the Cauca River (Antioquia), Northwestern Colombia
Abstract This study describes a new species of Croton section Geiseleria (Euphorbiaceae) based on specimens collected in remnants of vegetation in the municipality of Santa Fe de Antioquia (Antioquia), Northwestern Colombia. Croton antioquensis resembles C. adenodontus, C. bidentatus and C. subsuavis, however, it is differentiated by a set of characters associated with its floral and vegetative morphology, in addition to its geographic distribution. The new species is known from a single locality in an area of occupancy (AOO) of less than 4 km2 with multiple threats of anthropogenic origin. We suggest its inclusion in the category of Critically Endangered (CR) taking into account the IUCN guidelines. A key to the species of Croton sect. Geiseleria in Colombia is included.
