| 2:00a | [Crustacea • 2024] Cherax rayko & C. phing • Two New Species of Crayfish of the Genus Cherax (Decapoda: Parastacidae) from Western and Eastern Indonesian New Guinea
Abstract Two new species of the genus Cherax are described and illustrated. Cherax rayko n. sp., endemic to the Bian River drainage basin in the Muting District, in the northern part of the Merauke Regency, South Papua, Indonesia, is described, figured, and compared with its closest relatives, Cherax alyciae, Lukhaup, Eprilurahman & von Rintelen, 2018, and Cherax peknyi Lukhaup & Herbert, 2008. The new species may be easily distinguished from both by the shape of the rostrum, the shape of the chelae, the shape of the scaphocerite, and the coloration. Cherax phing n. sp., endemic to the Kali Ombak River drainage basin in the western part of the Kepala Burung (Vogelkop) Peninsula, Southwest Papua, Indonesia, is described, figured, and compared with its closest relatives, Cherax pulcher Lukhaup, 2015a, Cherax boesemani Lukhaup & Pekny, 2008, Cherax wagenknechtae Lukhaup and Eprilurahman, 2022, and Cherax gherardii Patoka, Bláha & Kouba, 2015. The new species may be easily distinguished from the latter species by the shape of the chelae, rostrum, and body and by the coloration. A molecular phylogeny based on a mitochondrial gene fragment, 16S, supports the morphology-based description of the two new species, which can also be clearly distinguished by sequence differences. Keywords: morphology; molecular phylogeny; freshwater; New Guinea; taxonomy
Cherax rayko n. sp. Etymology. Cherax rayko n. sp. is named after Rayko Eloy Lukhaup, the son of the
first author. Rayko was very present in the process of the description, providing love and
understanding. Ecology. It is endemic to the Bian River drainage basin and its tributaries. One of the
creeks harboring these crayfish is shallow (20–100 cm) with a moderate flow. The temperature is around 25–26 °C. In most parts, no water plants are present. The substrate of the
creek is silt or sand and soil mostly covered with silt and detritus. Crayfish hide in short
burrows in the riverbank, under larger rocks, or in detritus that is present in all the parts
of the creek. The creek is surrounded by forest. To improve the knowledge of the distribution of this species, more field surveys will be necessary. Common name. As the common name for this crayfish, we propose the Tiger Crayfish, as it is already available under this name in the pet trade. Cherax phing n. sp. Etymology. C. phing n. sp. is named in honor of Liauw Pauw Phing, a crayfish enthusiast, for his noteworthy contribution to the knowledge of the crayfish of Papua.
His continuing effort to search and find unknown species is very needed work for
our better understanding of the crayfish of this region. Common name. As a common name for this crayfish, we propose the Green Hornet
Crayfish, as it is already available under this name in the pet trade. Christian Lukhaup, Rury Eprilurahman and Thomas von Rintelen. 2024.

| 2:37a | [Botany • 2024] Henckelia arunachalensis (Gesneriaceae) • A New Species from Patkai Hills of Arunachal Pradesh, India
Abstract Repeated expeditions conducted since 2018 in Arunachal Pradesh led to the collection of several taxa of Gesneriaceae, many of which are newly described. Among these, a peculiar species from the Patkai Hills of Arunachal Pradesh is described here as Henckelia arunachalensis, a species new to science. This new species is allied to Henckelia dibangensis but differs in its elliptic to obovate leaves with 9–13 pairs of lateral veins (vs ovate to ovate-elliptic with 5–8 pairs of lateral veins), erect to perpendicular cymes with 1–5 flowers (vs pendulous cymes with 1–2 flowers), broadly ovate to ovate lanceolate bracts (vs linear bracts), a leathery calyx, pale green and puberulous outside, glabrous inside (vs light green, glabrous calyx), and a purplish white corolla with white flaps (vs a pale pink corolla with no flaps).

| 8:38a | [Botany • 2024] Primula shimokitana (Primulaceae) • A New Species from the Northernmost Honshu Island, Japan
Reexamination of the primrose on the Shimokita Peninsula, northernmost Honshu, Japan, which has been treated as Primula modesta Bisset & Moore showed that it is closely related to P. sorachiana Miyabe & Tatew., endemic to Hokkaido, based on morphology and phylogenetic investigations. However, it can be distinguished from P. sorachiana by its smaller stature, flowering scape shorter than leaves, base of bracts non-saccate, larger and fewer flowers, and shallowly parted calyx lobes. Based on the results, the plants from the Shimokita Peninsula are described as a new species, P. shimokitana Mas. Yamam.

| 9:54a | [Crustacea • 2024] Proasellus mikhaili • A New stygobiotic Species of the genus Proasellus Dudich, 1925 (Isopoda: Asellidae) from the Black Sea coast of the Caucasus, Russia
ABSTRACT A new stygobiotic species of water louses of the genus Proasellus Dudich, 1925 (Crustacea: Isopoda), P. mikhaili sp. n., is described from springs and groundwaters in the vicinity of the town of Tuapse on the Black Sea coast of the northwestern Caucasus, Russia. Representatives of this genus are reported for the first time from this coastal area. This new species is characterized by a number of unique features that immediately distinguish it from all known other Caucasian species of the genus. At present, this is the only species described from the region that has three connecting hooks in the retinacula of male pleopods I, as well as a shortened exopodite of pleopod V, significantly shorter than the endopodite in length. Among the diagnostic characters of this species are also a poor ornamentation of pereopods I–VII and a specific chetotaxis of the pleotelson represented by a dense covering of thin, hair-like setae. Probably, this species is an endemic of the Tuapsinsky District. KEY WORDS: Crustacea, Asellidae, new species, stygobionts, crenobionts, local endemism, Transcaucasia.

| 2:34p | [Botany • 2024] Psychotria oxyalabastron (Rubiaceae) • A New Species and A New Record of Psychotria from Thailand
Abstract A new species, Psychotria oxyalabastron, is described, and P. laui is newly recorded from Thailand. The description, distribution area, ecological information and taxonomic note are provided. Keywords: Gentianales, Psychotria laui, Psychotria oxyalabastron, Psychotrieae, Taxonomy
 Psychotria oxyalabastron T.Srisuk & Chamch., sp. nov. Psychotria oxyalabastron is similar to P. cambodiana Pierre ex Pit. in having tomentose, puberulous or pilose indumentum on branches and the lower leaf surface (at least on the venation), bifid or bilobed stipules, elliptic or oblanceolate laminas, loose corymbose-like thyrsiform inflorescences, and glabrous floral buds. However, it differs from P. cambodiana in the glabrous upper leaf surface (vs pilose), glabrous on intercostal areas on the lower leaf surface (vs pilose), acute floral bud apex with corolla protrusion (vs rounded floral bud apex without corolla protrusion), shorter corolla tube 1.3–1.4 mm long (vs 2–2.3 mm long), and the glabrous to sparsely puberulent ovary (vs tomentose or pilose). Etymology.— The specific epithet ‘oxyalabastron’ refers to the acute shape of the floral bud, and is modified from the Greek “oxy-” for acute, combined with “alabastrum” for floral bud (alabastron = adjective form).

| 3:51p | [Herpetology • 2024] Hidden on the Roof of the World: Mitochondrial Data Reveals Exceptional Genetic Diversity of Himalayan Ablepharine Skinks (Reptilia: Scincidae)
Abstract Snake-eyed, or ablepharine skinks, are common residents of the highest mountain ranges on Earth, including the Himalayas, the Tibetan Plateau, Karakoram, Pamir, and Tian Shan, colloquially known as the Roof of the World. Historically, these skinks were alternatively assigned to the genera Scincella, Ablepharus, Asymblepharus, and Himalblepharus, but recent revisions proposed to group them in only two genera, namely Protoblepharus (the eastern Himalayan taxa) and Ablepharus (all other taxa). The taxonomy of this group yet remains in a state of flux due to the limited informativeness of available phylogenies (often with little material from the Himalayan region), discrepancies in morphological patterns of variation, and the potentially high yet unconsidered degree of diversity of the group. To shed some light, we assess the mitochondrial diversity and evolution of Himalayan snake-eyed skinks based on >200 individuals sampled across Pakistan, India, Nepal, and China, representing nine out of ten Himalaya currently recognized species. Phylogenetic relationships were inferred from 2998 bp of mitochondrial sequences (12S, 16S, ND2, cyt b). Our analyses reveal a remarkably high cryptic diversity, including 14 to 16 species-level lineages within Ablepharus and four species-level lineages within Protoblepharus, which would substantially increase the number of species by at least twofold. This hidden diversity highlights the Himalayas as a center of phylogeographic diversification and endemism, likely shaped by geological and climatic factors associated with orogenesis, which now houses over half of the ablepharine skink species.
