| 7:52a | [Invertebrate • 2022] Tonoscolex kalimpongensis • A New Species of the Genus Tonoscolex Gates, 1933 (Clitellata: Megascolecidae) from India
Abstract Tonoscolex kalimpongensis Ahmed & Julka sp. nov. is described from Neora Valley National Park in the Kalimpong district of West Bengal, India. The new species is easily distinguished by the presence of one pair of spermathecal pores at intersegmental furrow 7/8. An updated checklist of the genus Tonoscolex and an identification key to the Indian Tonoscolex species are provided as well.

| 7:52a | [Botany • 2022] Garcinia yaatapsap (Clusiaceae) • A New Species from northern Myanmar
Abstract Garcinia yaatapsap (Clusiaceae), a new species from northern Myanmar, is described and illustrated. The new species is most similar to G. stipulata and G. nujiangensis, but differs primarily by its subsessile, subcordate to cordate leaves and strongly angled branchlets (versus petiolate, cuneate leaves and terete branches in G. stipulata and G. nujiangensis). Keywords: Dicrananthera, Discostigma, Guttiferae, Htamanthi Wildlife Sanctuary, Sagaing, taxonomy
Garcinia yaatapsap K. Armstr. & P.W. Sweeney, sp. nov. Type:—MYANMAR. Sagaing Region: Hkamti District, Hkamti Township, Htamanthi Wildlife Sanctuary, Just upstream from Nam Eizu camp 1,184 m. a.s.l., 25.537833°, 95.465861°, 11 September 2016, K. Armstrong, D. Daly, P. P. Hnin, T. Y. Nwe, L. Zaw, K. Z. Aung, H. Aung 1406 (holotype NY [NY02654830]!; isotypes E!, RAF!). Diagnosis:—Garcinia yaatapsap is similar to G. stipulata T.Anderson in Hooker (1874: 267) and G. nujiangensis C.Y.Wu & Y.H.Li in Li (1981: 494), but branchlets distinctly 4-sided and winged on angles (particularly distally) (vs. terete); leaf bases subcordate to cordate (vs. cuneate); leaves nearly sessile, petiole length to leaf blade length ratio smaller (ca. <1:25 vs. >1:16). Distribution and Habitat:—Garcinia yaatapsap has only been collected four times in the vicinity of Htamanthi Wildlife Sanctuary (Fig. 3) and is likely to be endemic to this area of the upper Chindwin Basin. This species occurs from 123-184 m a.s.l. in the Kachin-Sagaing low elevation evergreen subtropical rainforest ecosystem (Armstrong et al. 2020; Murray et al. 2020), which is a lowland (ca. 100-300 m a.s.l.) evergreen closed forest ecosystem in northern Myanmar, where there is abundant rainfall (2,000+ mm) and generally moist conditions. Etymology:—The specific epithet “yaatapsap” is the Shan-ni (Red Shan) vernacular name for the plant, which translates as “medicine to join the liver [back together]”. This epithet is constructed as a noun in apposition. Locally, a tea made from Garcinia yaatapsap is used as tonic for repairing a damaged liver due to drinking excess alcohol. Patrick W.

| 7:53a | [Fungi • 2022] Multi-locus Phylogeny unmasks Hidden Species within the Specialised Spider-parasitic Fungus, Gibellula (Ascomycota: Hypocreales: Cordycipitaceae) in Thailand
Abstract Over 80 species of hypocrealean fungi are reported as pathogens of spiders and harvestmen. Among these fungi, the genus Gibellula is highly regarded as a specialised spider-killer that has never been reported to infect other arthropods. While more than 20 species of Gibellula are known, few attempts to identify the infected spiders have been made despite the fact that the host specificity can help identify the fungal species. Here, we morphologically describe and illustrate eight new species of Gibellula and three new records from Thailand of known species along with the multi-gene phylogeny that clearly showed the segregation among the proposed species. Examination of the Gibellula-infected spider hosts identified Oxyopidae, Uloboridae and, for the first time, the ant-mimicking genus Myrmarachne. Keywords: Gibellula; araneogenous fungus; new taxa; spider predator  Gibellula Kuephadungphan, W.; Petcharad, B.; Tasanathai, K.; Thanakitpipattana, D.; Kobmoo, N.; Khonsanit, A.; Samson, R.A. and Luangsa-ard, J.J. 2022.

| 7:53a | [Phycology • 2022] Gracilaria khanjanapajiae (Rhodophyta: Gracilariales) • A New Species from the Andaman Coast of Thailand
ABSTRACT Taxonomy and diversity of the Gracilariaceae has been increasingly investigated by using integrated morphological and genetic approaches. The Indo-Pacific is likely a hotspot for diversity of these macroalgae. Collections of flattened Gracilaria samples from Natai beach, Andaman coast of Thailand, were morphologically and genetically analysed. Our results clearly indicated the presence of a new species, G. khanjanapajiae sp. nov., in Thailand. In comparison to other known Indo-Pacific flattened species, G. khanjanapajiae can be distinguished by its dentate blade margin, deep spermatangial conceptacles (verrucosa-type) and numerous lateral and basal nutritive filaments within mature cystocarps. This new species resembles G. srilankia in having similar branching pattern and male reproductive structures, but differs in blade margin features. Phylogenetically, G. khanjanapajiae was more closely related to G. spinulosa from Taiwan than other Thai and Indian Ocean species. This present study highlights the continuing discovery of Gracilaria diversity and distribution in the tropical Indo-Pacific.
