| 3:04a | [Entomology • 2025] Lamellipalpodes asmita • A New Species of non-luminous firefly (Coleoptera: Lampyridae: Ototretinae) from West Bengal, India with SEM study of mechano- and chemoreceptive sensilla
Highlights • A new species of Lamellipalpodes discovered from India. • For the first time, the mechanosensitive and chemosensitive sensilla of this subfamily have been described. • Twenty-four different sensilla has been identified. • A significant difference in the type of sensilla present in palpomeres and antennomeres has been observed. • Three sensilla of distinct morphology and a specialized apico-marginal sensory field on maxillary palps has been identified. Abstract A new species of non-luminous firefly, Lamellipalpodes asmita Chakrovorty & Bhattacharjee sp. nov. (Coleoptera: Lampyridae: Ototretinae) discovered from the campus of the University of Kalyani, West Bengal, India is described, illustrated and compared with other known species of the genus from India. The male genitalia, morphometry and other important characters are illustrated and described. Additionally, a dichotomous identification key to Indian Lamellipalpodes is provided. The mechanoreceptive and chemoreceptive sensilla of Lamellipalpodes asmita Chakrovorty & Bhattacharjee sp. nov. were studied utilizing scanning electron microscopy. Ten different types of sensilla namely, sensilla ampullacea, sensilla basiconica, sensilla chaetica, sensilla coeloconica, sensilla placodea, sensilla styloconica, sensilla trichodia, cone-shaped sensillum, dome-shaped sensilla, peg-like sensilla and their twenty-four different subtypes have been identified with maxillary and labial palps possessing eight subtypes not found on antennomeres. Cone-shaped, dome-shaped and peg-like sensilla were of distinct, previously unknown morphology. This study unravels the significance of the atypical maxillary palp and labial palp morphology of the species and sheds light on structure–function relationship of these unusual morphological features.

| 9:57a | [Botany • 2025] Lespedeza jianghuensis (Fabaceae) • A New Species from riparian meadows of Yangtze River basin, China
Abstract Lespedeza jianghuensis (Fabaceae), from Yangtze River basin, China, is described and illustrated as a new species. It is a dwarf shrublet occurring in the riparian meadows along the banks of rivers and lakes. It is morphologically similar to L. cuneata, L. lichiyuniae, and L. caraganae, but differs by its prostrate or decumbent habit, angulate but not furrowed stems, and small stipules (ca. 1 mm). Phylogenetic analyses based on combination of five chloroplasts fragments and ITS sequence confirmed that it belongs to Lespedeza sect. Junceae. We also evaluate its conservation status as Least Concern (LC). Key words: Fabaceae, morphological traits, new species, taxonomy, wetland
Lespedeza jianghuensis Song Huang, Jia X. Li & B. Pan bis, sp. nov. Diagnosis: L. jianghuensis is morphologically most similar to L. cuneata, in having narrow leaflets and straight lateral veins to the margin, but differs from the latter by its prostrate or decumbent habit (vs. erect or ascending), stems strongly branched at the base (vs. stems simple), branches with appressed-pubescent (vs. densely ascending-pubescent), leaves sparse (vs. leaves crowded), leaflets narrowly obovate, terminal leaflets 5–16 mm long (vs. cuneate or linear-cuneate, terminal leaflets 7–30 mm long in L. cuneata), abaxial surfaces of leaves pubescent with obvious veins (vs. densely whitish pubescent, veins indistinct), stipules triangular, 0.7–1 mm long (vs. lanceolate, 1–4 mm long in L. cuneata) and calyx lobes narrowly triangular (vs. lanceolate) (Fig. 5). Etymology: The specific epithet “jianghuensis” refers to the distribution area, with “jiang” standing for Yangtze River and its tributaries, and “hu” standing for the lakes in Yangtze River Basin.

| 2:23p | [Botany • 2025] Lilium huanglongense (Liliaceae) • A Newly-discovered Species in north-western Sichuan, China
Abstract In this study, we describe Lilium huanglongense, a newly-discovered lily species identified following extensive surveys in an undeveloped area of the Huanglong National Nature Reserve in Sichuan, China. This region, located in the Hengduan Mountains of south-western China, is recognised as one of the world’s prominent biodiversity hotspots, providing diverse habitats for a wide range of plant species. Morphologically, L. huanglongense resembles Lilium fargesii Franch., which is distributed in central China, as well as other tepal-recurved members of the section Lophophora (Bureau & Franch.) F. T. Wang & Ts. Tang. This section comprises dwarf lilies predominantly found in the alpine scrub of the Hengduan Mountains, extending westwards into the Himalayas. Molecular phylogenetic analyses using both nuclear ITS and chloroplast genomes confirm the independent status of the new species and its placement within the section Lophophora. The identification of this new species helps to fill the distribution gap between broad-leaved forest and alpine scrub species within the section, thereby enhancing our understanding of the diversity and distribution history of Lophophora. Key words: Liliaceae, Lilium huanglongense, Lophophorum-clade, new species, section Lophophora
Lilium huanglongense T.Wang & Y.D.Gao, sp. nov. Common name: 黄龙百合 huang long bai he Diagnosis: Lilium huanglongense is most similar to L. fargesii and L. stewartianum, but can be distinguished from L. fargesii by its yellow tepals and stamens that are longer than the pistil and, in contrast to L. stewartianum, L. huanglongense lacks a deep, slender floral tubes (the height of the cone formed by the connivent tepals) and has a trilobed, non-inflated stigma. (Table 1, Suppl. material 1: table S1) Etymology: The epithet adopted here is derived from Huanglong National Natural Reserve, the site of discovery of this species.

| 2:23p | [Herpetology • 2024] Diploderma qiaojiaense • A New Species of Diploderma Hallowell, 1861 (Squamata: Agamidae) from Northeastern Yunnan Province, China
Abstract A new species of the genus Diploderma Hallowell, 1861 from Qiaojia County, Zhaotong City, northeastern Yunnan Province, China, is described. Phylogenetically, the new species is placed within the D. splendidum complex and has genetic distances of 7.3% and 7.5% from D. splendidum (Barbour & Dunn, 1919) sensu stricto and D. daduense Cai, Liu & Chang, 2024, respectively, based on the ND2 gene sequences. Morphologically, the new species closely resembles D. splendidum sensu stricto and D. daduense, however, it can be distinguished from D. splendidum sensu stricto by having a larger body size in males and relatively shorter limbs, and can be differentiated from D. daduense by having a relatively narrower head in males and relatively shorter forelimbs in males. In addition, the new species differs from D. splendidum sensu stricto and D. daduense by having different colorations, especially in the absence of transverse stripes on the dorsal head. This study further revealed that D. splendidum sensu lato is a complex containing multiple species and that more research is needed to clarify the taxonomy of the complex. Keywords: morphology; ND2; Qiaojia County; systematics; taxonomy
Class Reptilia Laurenti, 1768 Order Squamata Oppel, 1811 Family Agamidae Gray, 1827 Genus Diploderma Hallowell, 1861 Diploderma qiaojiaense sp. nov. Diagnosis: Body size relatively large, SVL 88.4–95.9 mm in adult males; tail moderately long, TAL/SVL 2.17–2.29; limbs relatively short, FLL/SVL 0.39–0.42, HLL/SVL 0.69–0.73; head relatively long, HL/SVL 0.32–0.35; tympanum concealed; ventral head and body scales strongly keeled, some enlarged scales interspersed on ventral head; nuchal crest well-developed, dorsal crest moderately developed; strongly erected skin folds under nuchal and dorsal crests present. Dorsal surface of head light brownish grey with no transverse bands; transverse black stripe on upper lip indistinct, region between stripe beneath eye and stripe on upper lip pure white; dorsolateral stripe light green in males in life, upper edge straight or slightly jagged, lower edge straight; gular spot absent, some white spots with indistinct black circle surrounded present on ventral head; oral cavity, inner lips, and tongue light flesh color. Etymology: The specific epithet refers to Qiaojia County, which is where the new species was discovered.

| 4:23p | [Mollusca • 2025] Delectopecten thermus • Integrative Morphological, Mitogenomic and Phylogenetic Analyses reveal New Vent-dwelling Scallop Species (Bivalvia: Pectinidae: Camptonectinae)
Abstract Delectopecten is a small genus of the family Pectinidae (Bivalvia: Pectinida) that remains poorly studied in terms of both morphology and phylogeny. Here, we describe the first member of this genus from deep-sea hydrothermal vent ecosystems, D. thermus sp. nov., based on morphological investigations and molecular analyses of a specimen collected from the Higashi–Ensei vent field (962-m depth) in the northern Okinawa Trough. Morphologically, this new species resembles D. vancouverensis and D. gelatinosus in shell size, shape, auricle size and sculpture. However, D. thermus sp. nov. can be distinguished from its congeneric species (including 9 extant and 12 fossil species) by its unequal auricles (the anterior one being larger than the posterior), inwardly recurved anterior auricle of the left valve and a large byssal notch angle of ~90°. Comparisons of genetic sequences from three mitochondrial and three nuclear gene fragments supported the placement of the new species in the genus Delectopecten. Further phylogenetic analyses using these gene markers support that Delectopecten is monophyletic and positioned as an early diverging clade of the family Pectinidae. Additionally, the mitogenome of D. thermus sp. nov. was assembled and annotated, a first for its genus – revealing significant divergences in gene order compared to other pectinids. The 16S rRNA amplicon analysis of the gill tissue indicated that this vent-dwelling scallop does not exhibit symbiosis with chemosynthetic bacteria. A key to all known species of Delectopecten is provided to aid the identification of species in this understudied genus. Keywords: bivalvia, deep sea, Delectopecten, heterotrophy, Higashi–Ensei, hydrothermal vent, identification key, new species, Okinawa Trough, Pectinidae, systematics, taxonomy, trophic mode.
