| 2:30a | [Botany • 2022] Garcinia siripatanadilokii (Clusiaceae) • A New Species from Peninsular Thailand
Summary Garcinia siripatanadilokii Ngerns., Meeprom, Boonth., Chamch. & Sinbumr. (Clusiaceae), a new species discovered from tropical lowland evergreen rain forest, Peninsular Thailand, is described. A detailed morphological description and illustrations of the species are provided, along with information on recognition, distribution, specimens examined, habitat, conservation assessment, phenology, etymology, vernacular name and uses. Key Words: Garcinia sect. Brindonia, dioecious plant, edible fruits, Garcinia lanceifolia, Khao Chong, plant taxonomy, species nova, yellow latex      
Garcinia siripatanadilokii Ngerns., Meeprom, Boonth., Chamch. & Sinbumr., sp. nov. RECOGNITION. Garcinia siripatanadilokii is similar to G. lanceifolia in its habit (shrub or small tree), 4-merous flowers, sepals and petals decussate and concave, stigma radiate, shallowly lobed, papillate, fresh leaves crispy when crushed, fruits and leaves have a sour taste. Differences between these two related species are shown in Table 1. DISTRIBUTION. Known only from Peninsular Thailand: Khao Chong, Trang Province, Khlong Ton, Satun Province and Hala-Bala Wildlife Sanctuary, Narathiwat Province, but to be expected in Peninsular Malaysia. ETYMOLOGY. The specific epithet and Thai name are in honour of Dr Somkid Siripatanadilok, the former Associate Professor of the Department of Forest Biology, Faculty of Forestry. He taught the forest biology component of courses in field forest biology (in Peninsular Thailand, Khao Chong Botanical Garden is one of several study areas of the course), anatomy of trees, plant tissue culture and research techniques in forest biology (plant microtechniques) when the first author was an undergraduate student and a graduate student at Kasetsart University. He encouraged and supported the first author to work in the laboratory for plant tissue culture as an undergraduate student (1994 – 1997). He was the former co-advisor of the first author in his master's degree (1997 – 2000). He was a superb and a brilliant teacher, actively involved in many aspects of forest science in Thailand. VERNACULAR NAME. Som Kaeo Somkid (ส้มแก้วสมคิด) (suggested here); Som Kaeo (ส้มแก้ว) (Satun) (from A. F. G. Kerr 14580). USES. The ripe fruits are edible. The pericarp, sarcotesta, young shoots, leaves and flowers have a sour taste. It is suitable for cultivation as an ornamental.

| 3:37a | [Botany • 2022] Impatiens hambaeksanensis (Balsaminaceae) • A New Species from South Korea
Abstract A new species Impatiens hambaeksanensis from Gangwon-do, South Korea, is described and illustrated, based on its morphology and distribution. I. hambaeksanensis is different from I. furcillata, another similar Impatiens species in South Korea, in some ways: I. hambaeksanensis possesses a serrate leaf margin with flat tooth tip, while I. furcillata possesses a crenate leaf margin with erect tooth tip; it has an erect inflorescence, while I. furcillata has a pendulous inflorescence; it has a smaller flower which is 2–2.6 cm long, while I. furcillata has a flower of 2.3–3.2 cm; the flower is white or pinkish-white with yellowish and purplish spots, while I. furcillata has a white lower sepal and pinkish-white lateral united petals with yellowish spots; the distal part of the lower sepal is mostly not coiled or rarely 1-coiled, while that of I. furcillata is never coiled; the spur tip is expanded, round and slightly biparted, while that of I. furcillata is expanded, ellipsoidal and clearly biparted. A taxonomic description, a holotype and photos of morphological characteristics of the new species are provided. A table which includes the morphological comparison and a geographical distribution map are presented as well. Keywords: Gangwon-do, Korean endemic, morphology, new species, taxonomy
Impatiens hambaeksanensis B.U.Oh, sp. nov. Diagnosis: I. hambaeksanensis is similar to I. furcillata in its overall characteristics, including taproot, alternate phyllotaxis and racemose inflorescence, but different from it in some ways: I. hambaeksanensis has serrate leaf margin with flat tooth tip; inflorescence is erect; flower is smaller and mostly white or rarely pinkish-white; the distal part of the lower sepal is mostly non-coiled or rarely 1-coiled; the spur tip is expanded, round and slightly biparted.

| 4:06p | [Entomology • 2022] Dravidacris annamalaica • A New Pygmy Unicorn Grasshopper (Orthoptera: Tetrigidae) from South India
Abstract A new pygmy unicorn genus, Dravidacris Bhaskar et Kasalo, gen. nov., and its single species D. annamalaica Bhaskar et Kasalo sp. nov. are described, restricted to the Eastern coast of Tamil Nadu, one of the southern states of India. Dravidarcis gen. nov. is a unique pygmy grasshopper genus with its long, elevated, and projected vertex. Long and dorsally extended flat fastigium of Dravidacris gen. nov. is similar to that of Pseudomitraria from Africa, Rostella from SE Asia, and Indomiriatra from India. However, those species are different and are not closely related. The new genus is easily separated from the genera mentioned above by the shape of the horn, the way the horn is developed, the expression of medial and median carinae, and the shape of the anterior margin of the pronotum. The implications of differing horn morphologies are discussed, and some taxonomic comments are offered.

| 4:13p | [Crustacea • 2022] Cherax wagenknechtae • A New Species of Crayfish of the Genus Cherax (Decapoda: Parastacidae) from Indonesian New Guinea
Abstract A new species of the genus Cherax is described and illustrated. Cherax wagenknechtae sp. nov., endemic to the Beraur and Klasabun River drainages in the western part of the Kepala Burung (Vogelkop) peninsula, West Papua, Indonesia, is described, figured and compared with its closest relatives, Cherax pulcher Lukhaup, 2015. The new species may be easily distinguished from Cherax pulcher by the shape of the chelae, rostrum and body, and coloration. Key Words: freshwater, molecular phylogeny, morphology New Guinea, taxonomy  
Cherax wagenknechtae sp. nov. Diagnosis: Carapace surface covered with scattered small tubercles, three spines posterior to cervical groove on lateral carapace present. Eyes large, pigmented. Cornea as broad as eyestalk. Rostrum lance shaped with elevated, thickened margins, non-setose. Rostral margins with three prominent teeth. Posterior extensions of the rostral margins prominent. Postorbital ridges prominent with one acute spine at anterior terminus. Uncalcified patch on lateral margin of chelae of adult male, white, translucent. Propodal cutting edge with a few short setae in posterior part and one large tubercle. Chelae pinkish red, becoming dark red to black in the lateral and anterior part. Fixed finger and dayctyl with hooked yellow tips anteriorly. Dorsolateral margins of chelae slightly elevated, usually pink or creamy. Other walking legs blue-gray. Carapace and pleon pinkish red dorsally, becoming reddish gray laterally. Etymology. Cherax wagenknechtae sp. nov. is named after Sahra Wagenknecht, an outstanding German left-wing politician, economist, author and publicist. She inspired the first author to fight determinedly for a better and fairer future for us all. This is the best way we know to thank her for her much appreciated service and effort to represent the socially disadvantaged, her fight for freedom, peace and a rare talent to unite morals and politics.
