1. Two new empoascine leafhopper genera, Thaioasca and Mjolnirus, from Thailand (Hemiptera: Cicadellidae: Typhlocybinae), with a checklist of Empoascini in Thailand

   https://doi.org/10.11646/zootaxa.4915.2.4  

   WANG, YI-MEI; XU, YE; DMITRIEV, DMITRY A.; DIETRICH, CHRISTOPHER H.; QIN, DAO-ZHENG (January 2021, Zootaxa)

   Two new microleafhopper genera of Empoascini, Thaioasca Wang, Xu & Qin, gen. nov. and Mjolnirus Wang, Xu & Qin, gen. nov., based on the type species, Thaioasca contaminata Wang, Xu & Qin, sp. nov. and Mjolnirus mediolobus Wang, Xu & Qin, sp. nov. are described from Thailand. Male habitus photos and illustrations of male genitalia of these two new species are given. A checklist of Empoascini from Thailand is also provided.

2. The Furongian (late Cambrian) trilobite Thailandium’s endemicity reassessed along with a new species of Prosaukia from Ko Tarutao, Thailand

   The trilobite Thailandium solum is a large “saukiid” species known only from the Ao Mo Lae Formation of the Tarutao Group, Thailand. While the genus contains only one recognized species, Australian specimens from the Pacoota Sandstone were also assigned to it as indeterminate species by Shergold in 1991. Type material of Prosaukia misa, the type species of Prosaukia, as well as recent collections of Thailandium solum, Prosaukia tarutaoensis (Kobayashi, 1957), and a new species of Prosaukia, P. oculata, from Ko Tarutao, Thailand are used to reevaluate the generic identity of the Australian material through landmark-based morphometric analysis. The new material of Prosaukia and Thailandium, all from the Ao Mo Lae Formation, reveal that the Australian material is better characterized as Prosaukia, thus restricting the geographic range of Thailandium to Thailand and providing morphometric information by which to refine Thailandium’s generic diagnosis.

3. Two new species of Artocarpus (Moraceae) from Thailand and Vietnam

   https://doi.org/10.11646/phytotaxa.453.3.8  

   GARDNER, ELLIOT M.; CHAVEERACH, ARUNRAT; SUDMOON, RUNGLAWAN; ZEREGA, NYREE J.C. (July 2020, Phytotaxa)

   Recent taxonomic work on Artoarpus has revealed two undescribed species from Thailand and Vietnam. Artocarpus rubrosoccatus, endemic to peninsular Thailand, resembles A. lacucha but is distinguished by its deep red clavate staminate inflorescences. Artocarpus montanus is found in the montane regions of southern and central Vietnam, and perhaps also in Thailand. This species resembles the vegetative parts of A. lowii and A. excelsus, but A. montanus differs in its longer syncarp processes and its geographic distribution. The vast majority of Artocarpus species are found in tropical lowlands, and A. montanus, along with A. excelsus, represent the only known members of the genus that are restricted to montane habitats. The provisional conservation assessment of both new species is Near Threatened, because although their known areas of occupancy are restricted, both occur in protected areas.

4. New taxa and new records of Deltocephalini leafhoppers from Thailand (Hemiptera: Cicadellidae: Deltocephalinae)

   https://doi.org/10.11646/zootaxa.4350.2.10  

   DUAN, YANI; DIETRICH, CHRISTOPHER H.; WEBB, MICHAEL D.; ZHANG, YALIN (November 2017, Zootaxa)

   Two new genera and three new species of the leafhopper tribe Deltocephalini are described from Thailand, viz., Loeia Duan gen. n. with L. tamtipi Duan sp. n. as type species, Phetchabunia Duan gen. n. with P. janteabi Duan sp. n. as type species, and Maiestas subsirii Duan sp. n.. Five new country records for Thailand are also given, viz. Deltocephalus vulgaris Dash & Viraktamath, Maiestas dinghuensis Zhang & Duan, Maiestas scripta (Distant), Paramesodes sp., and Polyamia acicularis Dai, Xing & Li.

5. Re-evaluating Pleistocene–Holocene occupation of cave sites in north-west Thailand: new radiocarbon and luminescence dating

   https://doi.org/10.15184/aqy.2021.44  

   Conrad, Cyler; Shoocongdej, Rasmi; Marwick, Ben; White, Joyce C.; Thongcharoenchaikit, Cholawit; Higham, Charles; Feathers, James K.; Tumpeesuwan, Sakboworn; Castillo, Cristina C.; Fuller, Dorian Q.; et al (April 2022, Antiquity)

   Established chronologies indicate a long-term ‘Hoabinhian’ hunter-gatherer occupation of Mainland Southeast Asia during the Terminal Pleistocene to Mid-Holocene (45 000–3000 years ago). Here, the authors re-examine the ‘Hoabinhian’ sequence from north-west Thailand using new radiocarbon and luminescence data from Spirit Cave, Steep Cliff Cave and Banyan Valley Cave. The results indicate that hunter-gatherers exploited this ecologically diverse region throughout the Terminal Pleistocene and the Pleistocene–Holocene transition, and into the period during which agricultural lifeways emerged in the Holocene. Hunter-gatherers did not abandon this highland region of Thailand during periods of environmental and socioeconomic change.
