| 3:08a | [Botany • 2022] Impatiens albocolumba, I. aureiflora, I. phasiana, I. psittacula, I. thunbergioides, etc. (Balsaminaceae) • Impatiens of Thailand
Dr Piyakaset Suksathan and Dr Saroj Ruchisansakun present, in this book on the balsams of Thailand, their revision of the genus Impatiens (Balsaminaceae), a technically competent yet well-illustrated and engaging account of a plant group with very many elegant and exquisite species. For plant-lovers, especially, this comes some 130 years following the description of the first Thai species, Impatiens mirabilis Hook.f., in 1891. Since then, there have been many discoveries, including new records and new species, detailed in this book. The research has spanned over a decade, covering an incredibly attractive and interesting array of species spanning the longitudinally and latitudinally diverse inclusion of Thailand, ranging from subtropical mountains to the wet tropical lowland rainforest regions. Balsams have an impressive taxonomic diversity, their basic floral structure already elaborate, represented by an incredibly large variation in form and structure, amply displayed in this iconic taxonomic account. This beautiful book details 91 taxa including 20 new species and a new variety, with 43 species only known from Thailand. It is a gem not only for botanists and specialists, but also amateurs and plant lovers everywhere.  20 new species and a new variety from Thailand: • Calcicola group • Impatiens centralis Suksathan & Triboun endemic to Central Thailand • Impatiens chamchumroonii Suksathan & Ruchis. endemic to NE Thailand • Impatiens chunkaoi Suksathan & Panitvong endemic to Central Thailand • Impatiens nakhonsriensis Suksathan & Triboun endemic to southern Thailand • Impatiens phonsenae Ruchis. & Suksathan endemic to eastern Thailand • Impatiens wongnakii Suksathan & La-ongsri endemic to northern Thailand * Impatiens kanburiensis T.Shimizu var. phuphanensis Suksathan & Ruchis.) endemic to NE Thailand  • Damrongii group • Impatiens doiwaoensis Suksathan & Wongnak endemic to northern Thailand • Impatiens phasiana Suksathan & Triboun endemic to northern Thailand • Impatiens shimizuana Suksathan & Ruchis.) endemic to northern Thailand • Kerriae group • Impatiens kaweesakii Suksathan endemic to NE Thailand   • Mirabilis group • Impatiens poomae Suksathan & Ruchis. endemic to southern Thailand • Psittacina group • Impatiens albocolumba Suksathan & Ruchis. endemic to NE Thailand • Impatiens aureiflora Suksathan & La-ongsri endemic to northern Thailand • Impatiens chanburiensis Suksathan & Wongnak endemic to eastern Thailand • Impatiens micropsitta Suksathan & Ruchis. endemic to northern Thailand • Impatiens phayaoensis Suksathan & La-ongsri endemic to northern Thailand • Impatiens psittacula Suksathan & Ruchis. endemic to northern Thailand • Impatiens purpureoscopioides Triboun, Tanutong & Ruchis. endemic to western Thailand • Impatiens thunbergioides Suksathan & Triboun endemic to northern Thailand • Violiflora group • Impatiens nanensis Suksathan & Srisanga endemic to northern Thailand

| 3:26a | [Botany • 2023] Nothoscordum itapetinga (Amaryllidaceae: Allioideae) • Woken up from A Hundred-Year Sleep: A New Species from the Brazilian Atlantic Forest
Abstract Background and aims: Serra do Itapetinga houses one of the most important remnants of Atlantic Forest in the macrometropolis of São Paulo, the most populous region of Brazil. In the context of monographic works on Brazilian Nothoscordum species, a new species with current distribution restricted to Serra do Itapetinga was identified, and is described and illustrated here. M&M: Recognition of the new species is based on morphological, molecular and cytological data. Descriptions and morphological comparisons were obtained from examination of herbarium collections or living plants. Based on nuclear (ITS) and plastid (ndhF and matK) DNA markers, a molecular phylogeny including the described species is presented. Its conservation status was assessed using the IUCN Red List Categories and Criteria. Results: Nothoscordum itapetinga bears free staminal filaments, a typical morphological characters of sect. Nothoscordum. Its placement in sect. Nothoscordum is also supported by molecular data and base chromosome number. We provide its chromosome count along with karyotype formula and DNA content. Comments on its distribution, habitat and conservation are furnished. Conclusions: With the data available the new species is considered Critically Endangered (CR). The localities of occurrence suffered decades of impacts resulting from intensive and uncontrolled use, in addition to human-induced fires, which modified the vegetation structure and floristic composition. Following the efforts of locating additional records, urgent protection and conservation measures are required to ensure the survival of the remaining populations of N. itapetinga. Key words: conservation, cytogenetics, Leucocoryneae, molecular phylogeny, rocky outcrops, Serra do Itapetinga, threatened species   Nothoscordum itapetinga Campos-Rocha & Sassone, sp. nov. Diagnosis: Nothoscordum itapetinga can be considered morphologically similar to N. aparadense Ravenna, a species described from high-altitude damp lawns of Aparados da Serra, in Southern Brazil. They can be distinguished by scape length and leaf thickness (scape of similar length to or longer than the leaves, which are not thickened in N. itapetinga vs. scape shorter than the leaves, which are thickened in N. aparadense), in addition to individual plant size, usually taller in N. itapetinga. Furthermore, N. itapetinga is a species that occurs in vegetation islands on granite outcrops of Southeastern Brazil, possibly endemic to Serra do Itapetinga whereas N. aparadense grows in damp lawns on the top of Aparados da Serra (São Joaquim, Santa Catarina; Ravenna, 2001).

| 3:32a | [Ichthyology • 2023] Rhyacoglanis beninei • Description and Phylogenetic Position of A New Species of Rhyacoglanis (Siluriformes: Pseudopimelodidae) from the Jamanxim River Basin
Abstract In this study, a new species of Rhyacoglanis is described from the Jamanxim River basin, Tapajós River basin. The new species differs from congeners based on the combination of the following diagnostic characters: two oblique dark bands formed by an agglomerate of melanophores on the predorsal region; dorsal confluence between the dark subdorsal and subadipose bands in large juveniles and adults; ventral confluence between the dark subadipose and caudal peduncle bands; body without conspicuous dark brown spots; complete dark band on caudal peduncle; body with three dark bands; a thin dark caudal-fin band; pectoral-fin spine with anterior serrae distributed along the entire margin; the posterior tip of the post-cleithral process reaching vertical through the base of the dorsal-fin spine; and hypural 5 free of hypural 3 and 4 and pointed caudal-fin lobes. Additionally, our molecular phylogenetic results using ultraconserved elements (UCEs) corroborate the new species as Rhyacoglanis and sister to an undescribed species of Rhyacoglanis from the Xingu River basin. Moreover, as pointed out in previous studies, we confirm Cruciglanis as a sister group to Pseudopimelodus plus Rhyacoglanis. Keywords: Amazon basin; Bumblebee catfishes; Phylogenomic; South America region; Pseudopimelodinae
 
Rhyacoglanis beninei, new species Diagnosis. Rhyacoglanis beninei can be diagnosed from all congeners by two oblique dorsal dark brown bars on the predorsal region (Fig. 2) (vs. absent). Additionally, R. beninei is distinguished from some congeners by having a dorsal confluence between the dark subdorsal and subadipose bands in large juveniles and adults (> 28 mm SL) (vs. lack dorsal confluence in R. paranensis, R. annulatus, R. varii, and R. rapppydanielae); ventral confluence between the dark subadipose and caudal peduncle bands (vs. lack ventral confluence in R. annulatus, R. epiblepsis, R. paranensis, R. seminiger, and R. rapppydanielae); body without conspicuous dark brown spots (vs. conspicuous dark brown spots in R. epiblepsis and R. rapppydanielae); complete dark band on caudal peduncle (vs. caudal peduncle-band with a unpigmented central region in R. annulatus); body with three dark bands (vs. two dark bands in R. seminiger); a thin dark caudal-fin bands (vs. large caudal-fin bands in R. paranensis and R. epiblepsis); pectoral-fin spine with anterior serrae distributed along the entire margin (restricted to the proximal half in R. pulcher and R. seminiger); posterior tip of the post-cleithral process reaching vertical through the base of the dorsal-fin spine (vs. not reaching in R. epiblepsis and R. rapppydanielae); hypural 5 free of hypural 3 and 4 (vs. hypurals 4 and 5 fused in R. rapppydanielae); pointed caudal-fin lobes (vs. rounded lobes in R. epiblepsis). Etymology. Rhyacoglanis beninei is named in honor of Ricardo Cardoso Benine, Professor at Universidade Estadual Paulista “Júlio de Mesquita Filho”, in recognition of his dedication and remarkable contributions to the knowledge of Neotropical freshwater fishes.
