| 2:02a | [Cnidaria • 2024] Pseudopterogorgia nanjiensis • A New gorgonian (Octocorallia: Gorgoniidae) from the Nanji Islands, China
Abstract Members of the genus Pseudopterogorgia Kükenthal, 1919 are widely distributed in shallow water of the Indo-West Pacific. During an investigation of benthic biodiversity in the subtidal zone surrounding the Nanji Islands in the East China Sea, two specimens of Pseudopterogorgia were collected and described as a new species based on an integrated morphological-molecular approach. Pseudopterogorgia nanjiensis sp. nov. is most similar to P. fredericki Williams & Vennam, 2001 in the irregular branching form and indistinct scaphoids, but differs by the coenenchymal sclerite content of distinct capstans and a few warty spindles and radiates (vs. mostly warty spindles and a few capstans), and a purplish colony (vs. white, pink to deep rose). Molecular phylogenetic analyses, based on the mtMutS-COI gene sequences, delineated a monophyletic clade encompassing all assessed Pseudopterogorgia species. Within this clade, P. nanjiensis sp. nov. showed a close phylogenetic affinity with both P. fredericki and P. australiensis Ridley, 1884.

Pseudopterogorgia nanjiensis Sun, Xu & Zhan, sp. nov. Diagnosis: Colony non-pinnate and purplish. Branches divided dichotomously and irregularly, nearly in one plane. Polyp retracted and forming a small and oval-shaped protrusion. Sclerites in polyps small flat rodlets, colorless and rare to absent in numbers. Sclerites in coenenchyme red, mostly capstans, a few radiates and warty spindles, and rare scaphoids. Capstans have two whorls of tubercles and blunt ends with irregular arrangements of complex tubercles. Radiates and immature sclerites with two whorls of projections, spindles with 4–8 whorls of tubercles, and scaphoids with similar ornamentation of tubercles on both convex and concave sides.

| 2:14a | [Botany • 2024] Chiloschista breviseta (Orchidaceae: Epidendroideae) • A New Species from Northern Thailand
Abstract A new species, Chiloschista breviseta (Orchidaceae: Epidendroideae: Aeridinae) from Northern Thailand is described and illustrated, and notes on ecology and conservation status are provided. Chiloschista breviseta is morphologically similar to C. usneoides but differs in having much shorter seta on each side of the anther cap. Previous records of C. usneoides from Thailand refer to C. breviseta. Keyword: Aeridinae, Chiloschista, Chiloschista usneoides, Chiloschista viridiflava, Flora of Thailand, new taxon
Chiloschista breviseta Chanokkhun, Watthana & Schuit., sp. nov. Diagnosis: Chiloschista breviseta is similar to C. usneoides in the largely white flower and the shorts accate lip with a rudimentary mid-lobe, but differs in having a short seta (<0.3 mm long) on each side of the anther cap (vs. a long, thread-like seta, >1.7 mm long) and in the Y-shaped callus apex (vs. T-shaped). It can be distinguished from C. viridiflava Seidenf. in having a glabrous abaxial surface of sepals and petal (vs. pubescent), margin of petals entire (vs. erose), and white sepals and petals, sometimes with a purplish pink median line abaxially (vs. pure pale green), and in having short setae (vs. setae > 1.9 mm long). Etymology: From the Latin brevis, short, and seta, a
bristle-like hair, referring to the short appendages on the
anther cap, unlike the long wiry appendages seen in
species like C. usneoides Thotsaporn Chanokkhun, Nooduan Muangsan, Pongthep Suwanwaree, Rungtip Malaiphis, André Schuiteman and Santi Watthana. 2024. Chiloschista breviseta (Orchidaceae), A New Species from Thailand. Taiwania. 69(4); 449 - 453. DOI: 10.6165/tai.2024.69.449 | ||||||
| 2:14a | [Botany • 2022] Oreocharis hainanensis (Gesneriaceae) • A New Species from Karst Regions in Hainan Island, South China
Abstract Oreocharis hainanensis, a new species of Gesneriaceae is described and illustrated from low-altitudual karst areas in Hainan Island, South China. The new species is easily distinguished from its closely-related O. jasminina by campanulate floral tube, zygomorphic corolla and exserted stamens. It also shows different habitats from the four currently-recognized Oreocharis taxa on the island. Molecular phylogeny analysis based on plastid trnL-trnF and nuclear ITS1/2 sequences supported the delimitation of the new species, which forms a monophyletic clade with all the other Oreocharis taxa from Hainan Island. The roles of habitat and floral isolation in the evolution of the new species and its affinities are discussed. The species was assessed as Vulnerable (VU C1 and D2) according to IUCN Red List Categories and Criteria. Morphology, Molecular, New taxon, Karst, Eudicots   Oreocharis hainanensis S.J. Ling & M.X.

| 9:21a | [Botany • 2024] Sophora phulangkaensis (Fabaceae: Sophoreae) • A New Species from Thailand based on morphological and molecular evidence
Abstract Sophora phulangkaensis is illustrated and newly described here. The species shows similarities with its congener, S. exigua, by having an obovate terminal leaflet and up to 15 leaflets but differs in the floral parts. A morphological comparison between the two species is provided along with a discussion. The phylogenetic placement of the new species is presented and discussed based on molecular evidence by nuclear (ITS) and chloroplast markers (matK). The results suggest that the new species is nested into sect. Rubriflorae, which includes S. exigua and S. huamotensis. The circumscription of sect. Rubriflorae is expanded after being redefined by our findings. In addition, the updated key to species of the genus Sophora for the Flora of Thailand is given based on recent specimen observations. Additionally, lectotypes for S. exigua, S. tonkinensis, and S. violacea var. pilosa are designated. Keywords: Fabaceae; Leguminosae; Nakhon Phanom; Phulangka; Sophora; lectotypification; molecular phylogeny
Sophora phulangkaensis Mattapha, K.Khamm. & Suddee,
sp. nov. Closely related to S. exigua Craib, from which it differs by being a small shrub
0.5–2 m tall (vs undershrub up to 0.5 m tall in S. exigua), with sparse to dense
hairs on midrib and margins of leaf blade (vs densely tomentose in S. exigua,
particularly when young), presence of bracteoles (absent in S. exigua), the
standard 15–16 mm long (18–20 mm long in S. exigua), filaments hairy
at base with hairy anthers (glabrous in S. exigua), ovary densely strigose
(tomentose in S. exigua) and longer pods (7–13 cm long vs 5–7 cm long
in S. exigua). Etymology. The specific epithet refers to the name of Phu Langka National
Park, where the species was discovered. Mattapha, S.; Suddee, S.; Khammongkol, K. and Kiewbang, W. 2024.

| 11:58p | [Ichthyology • 2024] Limnichthys koreanus • A New Species of creediid fish (Acropomatiformes: Creediidae) from Korea
Abstract Limnichthys koreanus sp. nov. is described on the basis of the holotype and 11 paratypes from subtidal waters of Seogwipo, Jeju Island, Korea. The new species had previously been regarded as the Northern Hemisphere population of the anti-equatorial L. fasciatus, but molecular analyses of mitochondrial COI and 16S genes recovers deep genetic divergences of 9.4% and 15.0% between the new species and topotypical specimens of L. fasciatus. Limnichthys koreanus sp. nov. is distinguished from all other species of Limnichthys based on the following combination of colouration and morphological characteristics: 38-40 vertebrae; 0–6 dorsal saddles joining mid-lateral stripe; small infraorbital sensory pores; a single median interorbital pore; and well-developed vomerine teeth. Summary characters for comparative congeneric species are provided. Key words: benthic species, Jeju Island, sand burrower, taxonomy
Acropomatiformes Gill, 1893 (new Korean name: Ban-dit-bul-ge-reu-chi-mok) Creediidae Waite, 1899 (new Korean name: Byeol-ba-ra-gi-gwa) Limnichthys Waite, 1904 (new Korean name: Byeol-ba-ra-gi-sok) Limnichthys koreanus sp. nov. English name: Korean sand burrower; new Korean name: Tti-byeol-ba-ra-gi Diagnosis: Combined number of dorsal and anal fin rays 52–55; vertebrae 38–40; lateral line scales 42–46; a single median interorbital pore; vomerine teeth well developed; pelvic girdle separated each other; dorsal saddle patterns 5–9; dorsal saddles joining mid-lateral stripe 0–6 (Fig. 3A, Table 2). Etymology: The epithet of the new species, koreanus, refers to the type locality (Korea) where the species were collected.  Yu-Jin Lee and Jin-Koo Kim. 2024.
