| 2:25a | [Botany • 2024] Indigofera abbottii, I. ngwenyana, etc. (Fabaceae: Papilionoideae: Indigofereae) • New and poorly known Taxa of Indigofera from the Pondoland Centre of Endemism, South Africa: Part 2
Highlights: • Taxonomic description of new and little known Indigofera species from South Africa. • Four new Indigofera species, one new variety and two little known species are described. • One established taxon is raised to specific status and described with a new name. • An earlier name is found which has priority over an established species name. • All taxa are associated with the Pondoland Centre of Endemism, ranging to surrounding floristic areas. Abstract This second paper describes and clarifies new and poorly known Indigofera species, belonging to sect. Pinnatae (E.Mey.) Harv., from the Pondoland Centre of Endemism and associated neighbouring areas in the Eastern Cape and KwaZulu-Natal provinces, South Africa. Five new species (one with two infraspecific taxa) are recognized: Indigofera abbottii Schrire and K.W.Grieve, I. hillburttii Schrire and K.W.Grieve, I. tysonii Schrire and K.W.Grieve, I. herrstreyi Schrire and K.W.Grieve var. herrstreyi and I. herrstreyi var. helodes K.W.Grieve and Schrire, and I. ngwenyana Schrire and K.W.Grieve. Descriptions are provided for the poorly known I. corniculata E.Mey. and I. gerrardiana Harv., taxa rarely taken up in the literature and both having been mostly synonymised under I. dregeana E.Mey. that occurs outside the area of the present study. The name I. tenuissima E.Mey. was found to be the earliest, correct, name for the widespread species I. longipes N.E.Br. ex Baker f., leaving the coastal Zululand taxon – currently named I. tenuissima E.Mey. – requiring further evaluation.

| 2:25a | [Botany • 2020] Primulina titan (Gesneriaceae) • A New Species from Limestone Areas in Guangxi, China
Abstract A new species of Gesneriaceae, Primulina titan, is described and photographed from northern Guangxi, China. It resembles P. hunanensis, but can be distinguished by combined morphological characters of leaf, bract, corolla, stamen and pistil. We found only one population with approx. 800 mature individuals at the type locality. This species is provisionally assessed as vulnerable [VU D1] using IUCN criteria. Keywords: Flora of Guangxi, Limestone flora, Lithophytic, New taxon, Taxonomy
Primulina titan Z.B. Xin, W.C. Chou & F. Wen, sp. nov. Diagnosis: Primulina titan differs from P. hunanensis by its leaf blade glabrous (vs. covered with straight, pointed, white trichomes), petiole 1.2-2.5 cm in diam. (vs. 0.4-1.0 cm); bract pale green inside, margin obviously numerous serrate, sparsely pubescent outside, glabrous inside (vs. pink or purple-red inside, margin entire or repand, densely trichomes and pubescent outside, sparsely trichomes and pubescent inside); corolla white outside, with red-purple and brown stripes and spots inside ( vs. purple, with white stripes at corolla mouth); filament yellow, 1.5-1.7 cm long(vs. white, 0.8-1.2 cm); anther 7-8 mm long (vs. 3.5-4.5mm); pistil pale green, 4.2-5.0 cm long (vs. pale pink, 2.6-3.8 cm).

| 9:35a | [Invertebrate • 2024] Alloscopus arborealis • A New canopy-dwelling Species of the Genus Alloscopus Börner (Collembola: Orchesellidae: Heteromurinae) from Mt. Makiling, Philippines
Abstract A new species of Alloscopus Börner, 1906 (Orchesellidae: Heteromurinae), A. arborealis sp. nov., is herein described from Mt. Makiling, Laguna, Philippines. The new species is distinct from its blind congeners by the combination of: 7+7 macrochaetae on head ‘An’ series and 1+1 on ‘M’ series; 13+13 macrochaetae on thorax II (vs. 9–12) and 7+7 central on thorax III (vs. 6+6); absence of the microsensilla on abdomen I; abdomen IV with four sensilla (vs. three); and ventral tube with a small number of chaetae on its posterior face (4–5 vs. 11–23) and lateral flap (7 vs. 9–16). The complete body chaetotaxic pattern of the new species and a revised key to the world fauna of Alloscopus are also provided.

| 11:05a | [Mammalogy • 2024] Ecological Modeling, Biogeography, and Phenotypic Analyses setting the Tiger Cats’ Hyperdimensional Niches reveal A New Species, Leopardus pardinoides
Abstract Recently, the tiger-cat species complex was split into Leopardus tigrinus and Leopardus guttulus, along with other proposed schemes. We performed a detailed analysis integrating ecological modeling, biogeography, and phenotype of the four originally recognized subspecies—tigrinus, oncilla, pardinoides, guttulus—and presented a new multidimensional niche depiction of the species. Species distribution models used > 1400 records from museums and photographs, all checked for species accuracy. Morphological data were obtained from institutional/personal archives. Spotting patterns were established by integrating museum and photographic/camera-trap records. Principal component analysis showed three clearly distinct groups, with the Central American specimens (oncilla) clustering entirely within those of the Andes, namely the pardinoides group of the cloud forests of the southern Central-American and Andean mountain chains (clouded tiger-cat); the tigrinus group of the savannas of the Guiana Shield and central/northeastern Brazil (savanna tiger-cat); and the guttulus group in the lowland forests of the Atlantic Forest domain (Atlantic Forest tiger-cat). This scheme is supported by recent genetic analyses. All species displayed different spotting patterns, with some significant differences in body measurements/proportions. The new distribution presented alarming reductions from the historic range of − 50.4% to − 68.2%. This multidimensional approach revealed a new species of the elusive and threatened tiger-cat complex.
