| 4:11a | [Invertebrate • 2025] Kanchuria tripuraensis & K. priyasankari • Two New Earthworm Species of the Genus Kanchuria Julka, 1988 (Clitellata: Megascolecidae) from Tripura State, North-eastern India
Abstract Eastern Himalaya-Northeastern Hills are the second most earthworm species-rich region in India. Kanchuria Julka, 1988, is a small genus endemic to the north-eastern region of India, with eight known species. Two new species of the genus, namely Kanchuria tripuraensis Narayanan, Paliwal & Julka, sp. nov., and K. priyasankari Narayanan, Paliwal & Julka, sp. nov., are described from materials collected from the Tripura State in North-eastern India. K. tripuraensis sp. nov. is a unique species of the genus, distinguishable from all other known species by having single ventromedian spermathecae in segments 7 and 8. K. priyasankari sp. nov. belongs to the turaensis-species group characterized by three pairs of spermathecal pores. This group has a total of 5 species, including the new species described herein. Among the congeners of the group, K. priyasankari sp. nov. shows close similarity with K. turaensis Julka, 1988. K. priyasankari sp. nov. can be easily differentiated from the K. turaensis by the small body dimensions and characteristics of the spermathecae. The present work provides detailed descriptions of the new species along with photographs and illustrations of the key characters. A key to species of the genus Kanchuria is also provided. With the discovery of two new taxa, the total number of Kanchuria species has gone up to 10, and megadrile worm diversity reported from the Tripura State has increased to 38.

| 4:13a | [Botany • 2025] Camellia yangii (Theaceae) • A New Species of Tea Plants from Yunnan, China
Abstract Camellia sect. Thea contains plants of beverage sources with huge profits. Their natural germplasm resources have yet to be fully explored. Here, morphological, phenological and phylogenetic analyses were undertaken to reveal a new species of tea plants, C. yangii D.Wei Zhao. It is described with an illustration and photos of fresh characters provided. The new species is similar to C. fangchengensis and C. ptilophylla by the densely pubescent new branchlets, abaxial surface of leaves and pedicel, but differs from them in bearing a larger flower, fewer (3 vs. 5) but larger sepals, and the indumentum of the sepals. Molecular phylogenetic analysis using RPB2 introns 11–15 and 23 and waxy suggests that it is a member of C. sect. Thea and its phylogenetically closely related species are C. longissima and C. taliensis. Camellia yangii has a later flowering phase compared with other taxa of C. sect. Thea that occurred or were planted nearby, so it cannot naturally hybridize with other tea plants. The new species bears a red or purplish red and densely pubescent terminal bud, which suggests it is a rare germplasm resource of tea plants. Camellia yangii is only known from a single extremely vulnerable population and strict conservation and asexual propagations are urgently needed to avoid extinction.

Camellia yangii D.Wei Zhao, sp. nov.
Diagnosis. Similar to C. fangchengensis and C. ptilophylla by the densely pubescent new branchlets, abaxial surface of leaves and pedicel, but differs from them in bearing a larger flower (4–5.5 cm in diam. vs. 2–3.5 cm in diam.), less (3 vs. 5) but larger (8–9 × 10–13 mm vs. 2.5–7 × 3.5–7 mm) sepals, and sericeous (vs. glabrous) adaxial surface of the sepals (Table 1). Etymology. Camellia yangii is named after the leading collector of its type, Dr. Shixiong Yang, an expert of the family Theaceae at Kunming Institute of Botany, Chinese Academy of Sciences. The Chinese name of C. yangii is proposed as ”三萼茶” because it bears three sepals in the flower. Dongwei Zhao. 2025. Camellia yangii (Theaceae), A New Species of Tea Plants (Camellia section Thea).

| 2:29p | [Entomology • 2025] Ceraphron chularoipaad • Review of the Subgenus Larsoceraphron Dessart, 1981 of the Genus Ceraphron Jurine, 1807 (Hymenoptera: Ceraphronidae) with the Description of A New Species from Thailand
Abstract The subgenus Larsoceraphron Dessart, 1981 of the genus Ceraphron Jurine, 1807 is reviewed, and a new species, Ceraphron (Larsoceraphron) chularoipaad sp. nov., from Thailand is described and illustrated. This represents the first species-level record of the genus Ceraphron in Thailand. Additionally, we provide the redescriptions and illustrations of three previously known species viz., C. (L.) huggerti, C. (L.) sylviae, and C. (L.) tobiasi. We also include two identification keys for all known subgenera of Ceraphron and species of the subgenus Larsoceraphron.

Ceraphron (Larsoceraphron) chularoipaad Ghafouri Moghaddam, Salden & Butcher, sp. nov. Etymology. The specific epithet chularoipaad is derived from “Chula”, referring to Chulalongkorn University, and “roi paad”, which means “one hundred and eight” in Thai, commemorating the 108th anniversary of Chulalongkorn University in 2025. The name is treated as a noun in apposition. Mostafa Ghafouri Moghaddam, Tobias Salden, Minoo Heidari Latibari and Buntika A. Butcher. 2025.
