| 2:12a | [Botany • 2024] Didymocarpus pingyuanensis (Gesneriaceae) • A New Species endemic to Danxia Landscape from Guangdong Province, China, and two new combinations in Didymocarpus
Abstract Didymocarpus pingyuanensis, endemic to the Danxia landscape in Pingyuan County, Guangdong, China, is described and illustrated here. This species can be distinguished from other members of Didymocarpus sect. Heteroboea by its calyx deeply 5-lobed to about three quarters of its length. The phylogenetic position of the new species within Didymocarpus was examined using nuclear ribosomal internal transcribed spacer (ITS) sequences. Based on phylogenetics analysis and morphological evidence, we propose two new combinations, elevating the two varieties to species level, namely D. yinzhengii and D. gamosepalus. Key words: Didymocarpus heucherifolius var. gamosepalus, Didymocarpus heucherifolius var. yinzhengii, flora of Danxia, taxonomy
Didymocarpus pingyuanensis Ling H.Yang, Q.Fan & F.Wen, sp. nov. Diagnosis: Didymocarpus pingyuanensis is similar to D. heucherifolius var. gamosepalus and D. salviiflorus in having a similar zygomorphic corolla and pink to pinkish-purple funnel-shaped to tubular corolla tube, but can be distinguished from D. heucherifolius var. gamosepalus by its corolla size 1.8–3.8 cm long (vs. 3.6–4.3 cm long), calyx deeply 5-lobed to about three quarters of the calyx length, apex rounded, rarely cuspidate, overlapping at margin (vs. 5–lobed from middle to above middle); from D. salviiflorus, it differs by having calyx 5-lobed to about three quarters of the calyx length (vs. 5-lobed to about half of the calyx length from the base), bracts free, elliptic (vs. bracts free to connate, semiorbicular), and corolla glabrous outside (vs. puberulent outside). Etymology: The specific epithet refers to the type locality, Pingyuan County, Guangdong Province, China. The Chinese name of the new species is here given as 平远长蒴苣苔 (Píng Yuǎn Cháng Shuò Jù Tái).

| 3:37p | [Botany • 2024] Cattleya attenboroughiana (Orchidaceae: Laeliinae) • A New Species from the Diamantina Plateau, Minas Gerais, Brazil
Summary A new species of Cattleya ser. Parviflorae (Orchidaceae) is here described from the campos rupestres of the Diamantina Plateau, part of the Espinhaço Range, Minas Gerais, SE Brazil. The new species is named Cattleya attenboroughiana and it is here compared to the most similar taxa and illustrated with photographs. The new species is likely a microendemic but the available data is insufficient for a precise conservation status assessment, so we consider it Data Deficient (DD), reinforcing the need for further exploration in the Diamantina Plateau. Key Words: Campos rupestres, endemism, Espinhaço Range, orchid   Cattleya attenboroughiana E.L.F.Menezes, Giordani & R.A.Pinheiro sp. nov. ETYMOLOGY. The specific epithet is dedicated to Sir David Frederick Attenborough, a British anthropologist, naturalist, and documentary filmmaker who is an inspiration for new generations of scientists dedicated to the Natural Sciences, such as the authors of this work.

| 3:37p | [Mollusca • 2024] Pupinidius pulchellus • A New Species of Pupinidius Möllendorff, 1901 (Gastropoda: Stylommatophora: Enidae) from Jiuzhaigou, Sichuan, China
Abstract Background: The genus Pupinidius Möllendorff, 1901 is endemic in China and Nepal and consists of 15 species. China is the distribution centre of it with 12 species being recorded. New information: A new species, Pupinidius pulchellus Chen, Dai, Wu & Ouyang sp. nov. is described from Jiuzhaigou, Sichuan, China. It can be distinguished from congeneric species by the shell with wide and distinct radial stripes; the thin, slightly reflexed and reddish-brown peristome; the unpointed apex; the unfused A-1 and A-2; the sub-globular and well defined bursa copulatrix; the unexpanded diverticle and the presence of epiphallic caecum. Keywords: conchology, taxonomy, land snail, Sichuan
Pupinidius pulchellus Chen, Dai, Wu & Ouyang sp. nov. Diagnosis: Shell with wide and distinct radial stripes; peristome thin, slightly reflexed and reddish-brown; A-1 not fused with A-2; bursa copulatrix sub-globular and well defined; diverticle unexpanded; epiphallic caecum present. Etymology: The specific name is made from the Latin pulchellus for pretty, alluding to the pretty stripes on the shell of this species. Vernacular name: 丽纹蛹巢螺 (Pinyin: li wen yong chao luo). Zhong-Guang Chen, Yu-Ting Dai, Xiao-Ping Wu, Jiao Jiang and Shan Ouyang. 2024. A New Species of Pupinidius Möllendorff, 1901 (Gastropoda, Stylommatophora, Enidae) from Jiuzhaigou, Sichuan, China.
