| 9:09a | [Entomology • 2025] Chelonastichus hanssoni • A New Genus (Hymenoptera: Eulophidae: Tetrastichinae) from Thailand: the first eulophid with a metasomal carapace
Abstract Chelonastichus Ranjith & Quicke, gen. nov., is described based on a new species, C. hanssoni Ranjith & Quicke, sp. nov., from Thailand. Whereas most Eulophidae exhibit a delicate, collapsible body, the new genus, is the first known case within the family that possesses a coarsely-sculptured metasomal carapace formed by Gt5, with Gt2–4 short. The possible affinities of the new genus are discussed and it is tentatively placed in the Tetrastichinae. Keywords: New genus and species, oriental region, Southeast Asia, Tetrastichinae
Chelonastichus Ranjith & Quicke, gen. nov. Etymology. The genus name derived from a combination of a generic name from the family Braconidae, ‘Chelonus’ because of the first instance of carapace-like metasoma in the family Eulophidae and ‘astichus’ from the subfamily name Tetrastichinae where this genus is provisionally included.

(Hymenoptera, Eulophidae, Tetrastichinae) from Thailand: the first eulophid with a metasomal carapace. Journal of Hymenoptera Research. 98: 499-507. DOI: doi.org/10.3897/jhr.98.144864 | ||||||
| 9:19a | [Ichthyology • 2025] Campellolebias insularis • A New and threatened Species of internally inseminating Seasonal Killifish of Campellolebias (Cyprinodontiformes: Rivulidae) endemic to a continental island in the Atlantic Forest, Southern Brazil
Abstract Campellolebias comprises small internally inseminating seasonal fishes that inhabit temporary pools in tropical and subtropical areas of the Atlantic Forest. It currently encompasses four species. Integrative taxonomy was used here to investigate a possible new species found in the island of Florianópolis, southern Brazil. The examined material confirm that it pertains to a new species. Furthermore, minimum genetic distances found between this and other species of Campellolebias regarding mitochondrial markers were higher than 3 %. This new species is distinguished from all other species of Campellolebias by the combination of a series of character states, including the color pattern in both sexes, pelvic-fin bases separated by an interspace, pelvic-fin tips reaching base of the 1st anal-fin ray in males and the urogenital papilla in females, by possessing 1–2+24-29 infraorbital neuromasts, 2–4 otic neuromasts, and by the anal-fin origin being positioned at a vertical between the base of the 4th and 6th dorsal-fin ray in females. Campellolebias insularis, new species, occurs exclusively in small temporary wetlands in areas under strong threat due to real estate development, in the island of Florianópolis. Due to the advanced stage of habitat loss and degradation, its restricted distribution area, and the reduced populations sizes, the species is considered Critically Endangered. Additionally, comments are provided on the putative relationships of the new species, its conservation status, and an identification key for the species of Campellolebias.

| 9:40a | [Botany • 2021] Aristolochia luudamcui (Aristolochiaceae) • A New Species from northern Vietnam
Abstract Aristolochia luudamcui (Aristolochia subgen. Siphisia, Aristolochiaceae), a new species from Vietnam, previously misidentified as A. utriformis, is described and illustrated here. The new species is most similar to A. pseudoutriformis and A. utriformis concerning the morphology of the leaf lamina, the color of the perianth, and the shape of the limb, but A. luudamcui can be distinguished from the other two species by having a deeply 3-lobed limb and a glabrous, yellow inner surface of limb lobes. A detailed description, information on ecology, phenology, distribution, usage, a provisional assessment of the conservation status of the new species, and a comparison with morphologically similar species are provided as well. Keywords: Aristolochiaceae, Aristolochia utriformis, misidentified, Piperales, Siphisia, Magnoliids
Aristolochia luudamcui T.V.Do, sp. nov. Aristolochia luudamcui is most similar to A. pseudoutriformis and A. utriformis by sharing an ovate to lanceolate-ovate leaf blade, alight yellow perianth, and a saccate-shaped limb, but it clearly differs from these two species by having a deeply 3-lobed limb (vs.shallowly 3-lobed limb in both A. pseudoutriformis and A. utriformis) and a yellow, glabrous inner surface of limb lobes (vs. dark-red, dense processes in A. pseudoutriformis and black-purple, sparse processes in A. utriformis). Etymology:—The specific epithet honors Prof. Dr. Luu Dam Cu, a former vice-director of Vietnam NationalMuseum of Nature who strongly supported botanical research at the museum during the past years.

| 9:48a | [Arachnida • 2024] Evarcha tsipikafotsy, E. vavannyangisy & Thyene volombavatanany • Three New Species of plexippine jumping spiders (Salticidae: Salticinae: Plexippini) from dry forest in Boeny Region, north-western Madagascar
Abstract Despite being the most diverse family of spiders, Salticidae (jumping spiders) are poorly studied in Madagascar with only 47 of the total 105 species recorded in the last 100 years. Here, we describe three new species of Plexippini Simon, 1901 from dry forests in North-western Madagascar as part of an ongoing biomonitoring programme. This paper increases the number of species in the genus Evarcha Simon, 1902 from 93 to 95 and Thyene Simon, 1885 from 55 to 56. Additionally, we publish specimen records of Plexippus petersi (Karsch, 1878) from Madagascar for the first time. All new species are diagnosed and illustrated through photographs and drawings.

| 10:28a | [Botany • 2021] Zingiber ultralimitale subsp. matarombeoense (Zingiberaceae) • A New Subspecies from South-East Sulawesi, Indonesia
Abstract A new subspecies of Zingiber ultralimitale Ardiyani & A.D.Poulsen was found at Matarombeo, South-East Sulawesi. Zingiber ultralimitale subsp. matarombeoense Ardiyani & Ardi, was described, illustrated and barcoded using four barcoding loci (rbcL, trnH-psbA, Internal Transcribed Spacer-ITS, and matK). Provisional conservation status assessment indicates a Critical Endangered (CR) status. The taxonomic placement into section was determined based on morphology, molecular, and pollen SEM data.

| 11:07a | [Botany • 2021] Tillandsia oliveirae (Bromeliaceae: Tillandsioideae) • A New Species from an inselberg in Bahia, Brazil
Abstract The authors describe, discuss, and illustrate Tillandsia oliveirae, a new species from the inselbergs of the Caatinga biome in the municipality of Itatim, Bahia, Brazil. The new species is similar to T. hofackeri, differing by morphological characters such as larger size of the plant, longer peduncle, more laxly arranged leaves, which are more numerous, and whitish petals. It is an endemic species with a restricted area of distribution, being considered critically endangered (CR) due to illegal extractivism, specifically for regional and international trade.
